(1) Embodiment 1
(1.1) Overview Below, a master unit 1, which is an embodiment of a receiver according to the present disclosure, and an automatic fire alarm system 100 including the master unit 1 will be described with reference to the drawings.

As shown in FIG. 1, the parent unit 1 (receiver) of this embodiment is electrically connected to a pair of electric wires 31, 32 together with the child unit 2 (sensor), and can communicate with the child unit 2 by changing the current flowing through the pair of electric wires 31, 32. As shown in FIG. 2, the parent unit 1 is connected to a plurality of communication lines L1, with the pair of electric wires 31, 32 constituting one communication line L1. In addition, a plurality of child units 2 are connected to each of the plurality of communication lines L1.

As shown in FIG. 1, the parent unit 1 includes a receiving unit 14, a display unit 15, an acquisition unit 171, and a first change unit 172.

The receiver 14 receives signals transmitted from the slave unit 2 via the communication line L1. In particular, the receiver 14 receives a fire alert, which is a notification signal notifying the occurrence of a fire, from the slave unit 2.

The display unit 15 displays (outputs) fire information (display information, output information) showing information related to a fire (disaster prevention) based on the fire report received by the receiving unit 14. The fire information is expressed by at least one of letters, numbers, and symbols, and is displayed on the display unit 15 by, for example, letters, numbers, symbols, or a combination thereof. The content of the fire information includes, for example, information showing the communication line L1 connected to the handset 2 that notified the fire report, or information on the location where the handset 2 that notified the fire report is installed. The information showing the communication line L1 is, for example, a line number assigned in advance to each communication line L1, or information on the location where each communication line L1 is wired. The information on the location where the handset 2 is installed is, for example, the name of the location registered in advance in association with each handset 2 (the name of the location where the handset 2 is installed, for example, the room number in an apartment building), etc.

The display unit 15 is an example of a user interface unit that can output fire information related to fire (disaster prevention) based on the notification signal received by the receiving unit 14.

The acquisition unit 171 acquires user information related to the user who is using the base unit 1 (more specifically, for example, the face of the user). In this embodiment, the acquisition unit 171 is an imaging unit that captures an image including the face of the user who is using the base unit 1. That is, in this embodiment, the user information includes information obtained from an image captured of the user.

The first change unit 172 changes the display mode of the display information displayed on the display unit 15 based on the user information acquired by the acquisition unit 171. In this embodiment, the display mode is, for example, the type of language (Japanese, English, Chinese, etc.) used in the display information.

In this way, since the parent unit 1 of this embodiment includes the acquisition unit 171 and the first change unit 172, the display mode (output mode) of the display information (output information) displayed (output) on the display unit 15 can be automatically changed in accordance with the user. This makes it possible, for example, to automatically change the language used in the display information displayed on the display unit 15 to a language corresponding to the user.

(1.2) Overall Configuration In the following, a case where the automatic fire alarm system 100 of the present embodiment is used in an apartment building A1 (e.g., an apartment building) will be illustrated as an example, as shown in Fig. 2. Of course, the automatic fire alarm system 100 of the present embodiment may be used in various buildings, such as detached houses, commercial facilities, hospitals, hotels, and multi-tenant buildings, without being limited to the apartment building A1.

As shown in FIG. 2, the automatic fire alarm system 100 of this embodiment is provided with one parent unit 1 and multiple (here, 16) child units B1 to B16 for one apartment building A1. In addition, in this automatic fire alarm system 100, multiple (here, four) communication lines L1 (L11 to L14) are connected to the parent unit 1. Two or more (here, four) child units 2 are connected to each communication line L1. In detail, child units B1 to B4 are connected to communication line L11, child units B5 to B8 are connected to communication line L12, child units B9 to B12 are connected to communication line L13, and child units B13 to B16 are connected to communication line L14. In addition, at the end of each communication line L1 (the end opposite to the parent unit 1), a pair of electric wires 31 and 32 are electrically connected via a termination resistor C1. Therefore, the parent unit 1 can detect a break in the pair of electric wires 31, 32 by monitoring the current flowing between the pair of electric wires 31, 32. In the following explanation, when there is no need to distinguish between the child units B1 to B16, they will be referred to as "child unit 2."

Here, each of the multiple handset units 2 is either a first handset unit 21 or a second handset unit 22.

When the first handset 21 detects a fire, it shorts the pair of electric wires 31, 32, thereby transmitting a signal (hereinafter referred to as a "fire alarm") notifying the occurrence of a fire to the parent unit 1. That is, the first handset 21 here is a contact-type fire detector used in so-called P-type (proprietary-type) automatic fire alarm systems. When a fire alarm is transmitted from the first handset 21, the parent unit 1 cannot know which handset 2 (first handset 21) has transmitted the fire alarm. Therefore, in this case, the parent unit 1 identifies the source of the alarm on a communication line L1 basis.

When the second handset 22 detects the outbreak of a fire, it transmits a fire alert to the main unit 1 by communication using a transmission signal transmitted through a pair of electric wires 31, 32. Furthermore, after issuing an alert (after transmitting a fire alert), when the second handset 22 receives a transmission signal from the main unit 1 including an address request requesting the address (identifier) of the source of the fire alert, it transmits a pre-assigned address to the main unit 1 using the transmission signal. In other words, when a fire alert is transmitted from the second handset 22, the main unit 1 can identify the source of the alert on a handset 2 (second handset 22) basis by communicating with the second handset 22 that issued the alert.

The automatic fire alarm system 100 is basically configured to detect the occurrence of a fire using a slave unit 2, which is a detector (such as a heat detector, smoke detector, or flame detector), and to notify the occurrence of a fire (fire alarm) from the slave unit 2 to the master unit 1, which is a receiver. However, the slave unit 2 is not limited to a detector that detects the occurrence of a fire, and may also include a transmitter, etc. The transmitter is a device that has a push button switch (not shown) and notifies the master unit 1 of the occurrence of a fire by manually operating (pressing) the push button switch when a person discovers a fire.

The automatic fire alarm system 100 may have a function of linking with other equipment, such as a smoke control system (not shown) or an emergency broadcast system (not shown). In this case, the automatic fire alarm system 100 can control the fire doors of the smoke control system in the event of a fire, or can notify the emergency broadcast system of the occurrence of a fire by sound or voice.

Generally, there are two types of automatic fire alarm systems: proprietary type (P type) and record type (R type). In a P type automatic fire alarm system, the slave unit notifies the master unit of a fire by electrically shorting a pair of wires. In an R type automatic fire alarm system, the slave unit notifies the master unit of a fire by communicating with the master unit using a transmission signal transmitted along a transmission line.

The automatic fire alarm system 100 of this embodiment is based on the P type. In the automatic fire alarm system 100 of this embodiment, it is assumed that in an apartment building A1 where a P type automatic fire alarm system was installed, the existing wiring (communication line L1) is used as is, and the parent unit 1 and multiple child units 2 (first child unit 21, second child unit 22) are replaced. Here, some of the child units 2 may be the existing child units as is. Of course, the automatic fire alarm system 100 of this embodiment can also be adopted as a newly installed automatic fire alarm system.

The configuration of the parent unit 1 and child unit 2 will be described in detail below. Note that, in the following, one of the multiple child units 2, the first child unit 21, and one of the multiple child units 22 will be described, and a description of the remaining child units 2 will be omitted. In the following, the description will focus on one communication line L1 of the multiple communication lines L1.

(1.3) Configuration of the slave units First, the configuration of the slave units 2 (first slave unit 21 and second slave unit 22) will be described with reference to Fig. 1. Fig. 1 illustrates one each of the first slave unit 21 and the second slave unit 22, which are made up of sensors connected to one communication line L1, and does not illustrate the other slave units 2. Each slave unit 2 is installed in a room, staircase, hallway, etc. of the apartment building A1.

As shown in FIG. 1, the first slave unit 21 includes a (first) diode bridge 211, a (first) power supply unit 212, a (first) sensor 213, a thyristor 214, and a drive unit 215.

The diode bridge 211 has an input terminal electrically connected to a pair of electric wires 31, 32, and an output terminal electrically connected to a power supply unit 212 and a thyristor 214. The power supply unit 212 generates power for operating the first handset 21 by receiving power from the pair of electric wires 31, 32. The sensor 213 detects the occurrence of a fire by detecting, for example, a change in smoke concentration, a change in temperature, or a change in gas concentration such as carbon monoxide. The drive unit 215 shorts the pair of electric wires 31, 32 by turning on the thyristor 214 according to the output of the sensor 213.

With this configuration, when the first slave unit 21 detects the occurrence of a fire, it turns on the thyristor 214 to electrically short-circuit the pair of electric wires 31, 32, thereby notifying the master unit 1 of a fire alert.

As shown in FIG. 1, the second handset 22 includes a (second) diode bridge 221, a (second) power supply unit 222, a (second) sensor 223, a transmitter 224, a receiver 225, a controller 226, and a memory unit 227.

The diode bridge 221 has an input end electrically connected to a pair of electric wires 31, 32, and an output end electrically connected to a power supply unit 222, a transmitter 224, and a receiver 225. The power supply unit 222 generates power for operating the second slave unit 22 by receiving power from the pair of electric wires 31, 32. The sensor 223 detects the occurrence of a fire by detecting, for example, a change in smoke concentration, a change in temperature, or a change in gas concentration such as carbon monoxide. The control unit 226 controls the transmitter 224 and receiver 225 to transmit a fire alert and a transmission signal from the transmitter 224 to the master unit 1 and to receive a transmission signal from the master unit 1 at the receiver 225 according to the output of the sensor 223.

The transmitter 224 transmits a signal to the parent unit 1 by changing the current flowing through the pair of electric wires 31, 32. In other words, the transmitter 224 transmits a current signal to the parent unit 1 by drawing in and changing the current from the pair of electric wires 31, 32.

The receiver 225 receives the transmission signal from the parent unit 1 as a voltage signal (voltage change) on the pair of electric wires 31, 32. In other words, the current value of the current drawn by the parent unit 1 from the pair of electric wires 31, 32 corresponds to the magnitude of the voltage drop across resistor 12. Therefore, the receiver 225 receives the signal represented by the current value of the current drawn by the parent unit 1 as a voltage signal.

The memory unit 227 stores an address (identifier) that is assigned in advance to the second handset 22. A unique address is assigned to each of the multiple second handset units 22. Each address is associated with the installation location (e.g., room number) of each of the multiple second handset units 22 and stored in the memory unit 20 of the parent unit 1.

(1.4) Configuration of the Master Unit The master unit 1 in this embodiment has a function as a P-type receiver that receives a notification of a fire outbreak (fire alert) from the slave unit 2. The master unit 1 is installed, for example, in a management room of a building (apartment building A1).

As shown in FIG. 1, the parent unit 1 includes a receiving unit 14, a display unit 15 (user interface unit), and an acquisition unit 171, as well as an application unit 11, a resistor 12, a transmission unit 13, an operation unit 16, a control unit 17, a memory unit 20, a backup power supply 18, and a communication interface (referred to as "communication I/F" in FIG. 1) 19.

The application unit 11 is controlled by the control unit 17 to apply a predetermined voltage to the pair of electric wires 31, 32. As an example, the voltage applied by the application unit 11 between the pair of electric wires 31, 32 is 24 V DC, but this is not intended to be limiting.

The resistor 12 is connected between the application unit 11 and at least one of the pair of electric wires 31, 32. In the example of FIG. 1, the resistor 12 is inserted between one (high potential side) electric wire 31 of the pair of electric wires 31, 32 and the application unit 11. However, this is not the only example, and the resistor 12 may be inserted between the other (low potential side) electric wire 32 and the application unit 11, or between both of the pair of electric wires 31, 32 and the application unit 11.

The resistor 12 has two functions: a first function of converting the current flowing through the resistor 12 into a potential difference (voltage) between both ends of the resistor 12 by a voltage drop, and a second function of limiting the current flowing through the pair of electric wires 31, 32 when the pair of electric wires 31, 32 are shorted. In short, the resistor 12 has both a first function as a current-voltage conversion element and a second function as a current limiting element. Here, as an example, the resistance value of the resistor 12 is set to 470 Ω, but this is not intended to be limited to this value.

The transmitter 13 is electrically connected between the resistor 12 and the pair of electric wires 31, 32. The transmitter 13 transmits a transmission signal to the second handset 22 by changing the current flowing from the pair of electric wires 31, 32. In other words, the transmitter 13 transmits a transmission signal to the second handset 22 by changing the current flowing through the pair of electric wires 31, 32 by drawing in the current flowing from the application unit 11 to the resistor 12.

The receiver 14 is electrically connected between the resistor 12 and the pair of electric wires 31, 32. The receiver 14 distinguishes between a state in which the pair of electric wires 31, 32 is short-circuited by the first handset 21 and a state in which the pair of electric wires 31, 32 is not short-circuited. The receiver 14 thereby receives a fire alert transmitted by the first handset 21 shorting the pair of electric wires 31, 32.

The receiver 14 also receives the signal transmitted from the second handset 22 as a voltage change between the pair of electric wires 31, 32 by drawing current from the pair of electric wires 31, 32. In other words, the current value of the current drawn by the second handset 22 from the pair of electric wires 31, 32 corresponds to the magnitude of the voltage drop across the resistor 12. Therefore, the receiver 14 receives, as a transmission signal, the voltage change (voltage signal) that occurs on the pair of electric wires 31, 32 when the second handset 22 changes the current drawn from the pair of electric wires 31, 32. The receiver 14 also receives the address that the second handset 22 transmits in response to the address request. This allows the master unit 1 to know which second handset 22 has notified the fire alarm.

The display unit 15 is provided, for example, on the front of the housing of the parent unit 1. The display unit 15 displays various information. As shown in FIG. 3, the display unit 15 includes a plurality of indicator lights 151 and a liquid crystal display unit 152.

Each of the multiple indicator lights 151 is equipped with, for example, an LED (Light Emitting Diode). The control unit 17 controls the lighting, extinguishing, blinking, etc. of each of the multiple indicator lights 151. Some of the multiple indicator lights 151 (in the example of FIG. 3, the 20 indicator lights 151 on the left side) are respectively associated with multiple communication lines L1. Each of these indicator lights 151 associated with the communication line L1 is equipped with, for example, a red LED, and when it is lit, it indicates that a fire alarm has been notified through the corresponding communication line L1, and when it blinks, it indicates that a break has occurred in the corresponding communication line L1. In addition, some of the other indicator lights 151 respectively indicate the state of the parent unit 1. These indicator lights 151 include, for example, a transmitter light equipped with a red LED, an AC power light equipped with a green LED, a trouble light equipped with a red LED, etc. The transmitter light blinks to indicate that the push button of a transmitter connected to any of the communication lines L1 has been pressed. The AC power light turns on to indicate that the parent unit 1 is powered on. The trouble light blinks to indicate that there is an abnormality in the parent unit 1 or one of the communication lines L1.

The LCD display unit 152 displays various information under the control of the control unit 17. The LCD display unit 152 displays information using at least one of letters, numbers, and symbols. In particular, the LCD display unit 152 displays information indicating the contents of the fire report received from the handset 2. The LCD display unit 152 displays, as fire information (display information, output information), information indicating, for example, that a fire has occurred, the floor on which the fire has occurred, or the location on which the fire has occurred. The LCD display unit 152 also displays information (including confirmation messages, etc.) when making various settings of the automatic fire alarm system 100.

The operation unit 16 accepts input operations when performing various settings of the automatic fire alarm system 100. The operation unit 16 is equipped with a plurality of push buttons 161. The plurality of push buttons 161 includes a selection switch button for switching the display content displayed on the liquid crystal display unit 152, and an execution switch button for executing the display content displayed on the liquid crystal display unit 152. The plurality of push buttons 161 further includes an input switch button for displaying letters, numbers, symbols, etc. on the liquid crystal display unit 152.

Here, the communication interface 19 is a card slot into which a recording medium such as a memory card can be inserted. The communication interface 19 transmits information stored in the inserted card slot to the control unit 17 in response to, for example, an input operation to the operation unit 16. Note that the communication interface 19 may also be a connector to which a communication line from an external device is connected.

The backup power supply 18 is equipped with a storage battery. Here, the parent unit 1 uses a commercial power supply, a private power generating facility, etc. as its main power supply. The application unit 11 automatically switches the power supply source from the main power supply to the backup power supply 18 when the main power supply is interrupted, and automatically switches from the backup power supply 18 to the main power supply when the main power supply is restored. In this way, by providing the backup power supply 18, it is possible to ensure a power supply for the operation of the automatic fire alarm system 100 even in the event of a power outage.

The acquisition unit 171 acquires user information related to the user who is using the parent unit 1. The user information acquired by the acquisition unit 171 is output to a first change unit 172 (described later) of the control unit 17. In this embodiment, the acquisition unit 171 is an imaging unit that captures an image including the face of the user who is using the parent unit 1. The imaging unit is configured, for example, by a CCD image sensor. In this embodiment, the imaging unit captures a video, but may capture a still image. One frame of the video captured by the imaging unit is used as the user information. The imaging unit is provided in the parent unit 1 so as to capture an image of a person who is in a predetermined position around the parent unit 1 and is trying to view the display information displayed on the liquid crystal display unit 152 of the parent unit 1. The imaging unit is provided at a predetermined location around the liquid crystal display unit 152 on the front side of the housing of the parent unit 1 (see FIG. 3).

The control unit 17 controls the transmission unit 13 and the reception unit 14 to transmit a signal from the transmission unit 13 and to receive a signal from the handset 2 at the reception unit 14. The control unit 17 also controls the on/off of the indicator light 151 of the display unit 15 and controls the display content displayed on the liquid crystal display unit 152. The control unit 17 mainly comprises, for example, a computer having a CPU (Central Processing Unit) and memory, and realizes various functions by executing a program stored in the memory with the CPU. The program may be recorded in the computer's memory in advance, may be provided by recording it on a recording medium such as a memory card, or may be provided via a telecommunications line such as the Internet.

When the receiver 14 receives a fire alert via any of the communication lines L1, the control unit 17 turns on the indicator light 151 based on the fire alert, and also displays fire information indicating information related to the fire on the liquid crystal display unit 152. In one example, the content of the fire information includes information indicating the communication line L1 connected to the handset 2 that notified the fire alert. For example, when the control unit 17 receives a fire alert from the first handset 21, the control unit 17 displays information indicating the communication line L1 that received the fire alert on the liquid crystal display unit 152. In another example, the content of the fire information includes information on the location where the handset 2 that notified the fire alert is installed. For example, when the control unit 17 receives a fire alert from the second handset 22, the control unit 17 displays information indicating the second handset 22 that received the fire alert on the liquid crystal display unit 152 based on the address transmitted from the second handset 22. The content of these fire information (content displayed on the liquid crystal display unit 152) is stored in the memory unit 20. The control unit 17 reads information from the memory unit 20 based on which communication line L1 and/or slave unit 2 sent the fire alert, and displays the read information on the LCD display unit 152.

For example, if the communication line L11 is wired to the first floor of the apartment building A1, when the receiver 14 receives a fire alert via the communication line L11, the control unit 17 causes the liquid crystal display unit 152 to display information indicating that a fire has broken out on the first floor. In this case, for example, a message such as "1F HOUSEHOLD FAILURE" is displayed on the liquid crystal display unit 152.

For example, if handset B1 is the second handset 22 and is installed in room 1021 of apartment complex A1, when the receiver 14 receives a fire alert from handset B1, the control unit 17 causes the liquid crystal display 152 to display information indicating that a fire has broken out in room 1021. In this case, for example, a message such as "1021 Room Fire" is displayed on the liquid crystal display 152.

The control unit 17 in this embodiment includes a first change unit 172 that changes the display format (e.g., language) of the display information (e.g., fire information) displayed on the liquid crystal display unit 152.

The first change unit 172 changes the display mode of the display information displayed on the liquid crystal display unit 152 based on the user information acquired by the acquisition unit 171 (in this embodiment, a captured image including the user's face).

More specifically, the first change unit 172 first uses face recognition technology to determine whether or not a human face is captured in the captured image captured by the acquisition unit 171. If the first change unit 172 determines that a human face is captured in the captured image, it regards the captured image (one frame of image) as user information. Then, the first change unit 172 identifies the user who is using the parent unit 1 based on the user information acquired from the acquisition unit 171. More specifically, in this embodiment, the user information includes information obtained from the captured image including the user's face. In the storage unit 20, a captured image of the user's face is stored (registered) as a matching image for each user in advance. That is, a user who uses the parent unit 1 has registered a matching image of the user's face in advance in the storage unit 20. The above matching image is stored in association with the user's identification information (e.g., name). The first change unit 172 compares the captured image acquired by the acquisition unit 171 (i.e., the captured image including the user's face) with a plurality of matching images preregistered in the storage unit 20. More specifically, the first change unit 172, for example, extracts facial feature points from the user information and the reference image, and authenticates the face (person) based on the degree of agreement of the feature points. Then, the first change unit 172 identifies a matching image of the same face as the face included in the captured image acquired by the acquisition unit 171 from among the plurality of matching images. In this way, the first change unit 172 identifies the user who is using the base unit 1 based on the user information acquired by the acquisition unit 171.

The first change unit 172 changes the display mode of the display information displayed on the liquid crystal display unit 152 to a candidate mode corresponding to the specified user from among multiple candidate modes (e.g., Japanese, English, Chinese, etc.). In this embodiment, the display mode is the type of language (Japanese, English, Chinese, etc.) used in the display information displayed on the liquid crystal display unit 152. That is, in this embodiment, the display information displayed on the liquid crystal display unit 152 is stored in the memory unit 20 in multiple candidate modes (Japanese, English, Chinese, etc.). The users (e.g., Mr. A, Mr. B, Mr. C, Mr. D) registered in the parent unit 1 are associated with one of the multiple candidate modes (Japanese, English, Chinese, etc.). For example, Mr. A and Mr. D are associated with the Japanese display mode, Mr. B is associated with the English display mode, and Mr. C is associated with the Chinese display mode. The first change unit 172 changes the display mode of the display information displayed on the liquid crystal display unit 152 to a candidate mode corresponding to the specified user from among the multiple candidate modes. As a result, for example, if the user using parent unit 1 is Mr. A, the display information displayed on liquid crystal display unit 152 is displayed in a Japanese display format corresponding to Mr. A. Also, if the user using parent unit 1 is Mr. B, the display information displayed on liquid crystal display unit 152 is displayed in an English display format corresponding to Mr. B.

If the first change unit 172 does not acquire user information, or if it acquires user information but is unable to identify the user, it displays the display information on the liquid crystal display unit 152 in Japanese (i.e., the default language).

In this way, the first change unit 172 changes the display mode of the display information displayed on the liquid crystal display unit 152 based on the user information, and automatically changes the display mode of the display information displayed on the liquid crystal display unit 152 to a display mode that corresponds to the user according to the user.

The first change unit 172 also changes the display mode of the display information displayed on the liquid crystal display unit 152 based on the input operation of the operation unit 16. More specifically, when a display mode is specified by the input operation of the operation unit 16, the first change unit 172 changes the display mode of the display information displayed on the liquid crystal display unit 152 to the display mode specified by the input operation of the operation unit 16.

When an automatic change and a manual change overlap in changing the display mode of the display information displayed on the liquid crystal display unit 152, the first change unit 172 prioritizes the manual change. As a result, even if the display mode of the display information displayed on the liquid crystal display unit 152 is automatically changed to, for example, English, it is possible to manually change the display mode to a language other than English by inputting information into the operation unit 16. Note that an automatic change is when the first change unit 172 automatically changes the display mode of the display information displayed on the liquid crystal display unit 152 based on user information. A manual change is when the first change unit 172 changes the display information displayed on the liquid crystal display unit 152 based on inputting information into the operation unit 16.

(1.5) Operation of the Master Unit 1 Next, the operation of the master unit 1 will be described with reference to Fig. 4. In the following description, a case where fire information is displayed on the liquid crystal display unit 152 of the master unit 1 will be illustrated as an example of display information.

When a fire breaks out, the receiving unit 14 of the parent unit 1 receives a fire alert from the detector 2 that detected the fire (S1). When the receiving unit 14 of the parent unit 1 receives the fire alert, the control unit 17 displays the fire information on the liquid crystal display unit 152 in the default display mode (for example, Japanese) (S2). Then, the first change unit 172 of the parent unit 1 judges whether the acquisition unit 171 has acquired user information (S3). If the first change unit 172 judges that the acquisition unit 171 has not acquired user information as a result of this judgment, the process returns to step 2. Then, the process is continued from step S2. On the other hand, if the first change unit 172 judges that the acquisition unit 171 has acquired user information as a result of the judgment in step S3, the first change unit 172 identifies the user who is using the parent unit 1 (i.e., the user who is looking at the liquid crystal display unit 152) based on the user information acquired by the acquisition unit 171 (S4). If the first change unit 172 is unable to identify the user based on the user information as a result of this identification, the process returns to step S2. Then, the process continues from step S2.

On the other hand, as a result of the processing in step S4, if the control unit 17 identifies the user using the parent unit 1 based on the user information, it selects a candidate mode (e.g., English) corresponding to the identified user from among multiple candidate modes (multiple languages such as Japanese, English, Chinese, etc.). The control unit 17 then changes the fire information displayed on the liquid crystal display unit 152 to the selected candidate mode (S5). As a result, the language (Japanese) used in the fire information displayed on the liquid crystal display unit 152 is changed to a language (e.g., English) corresponding to the user viewing the fire information.

Then, the first change unit 172 judges whether or not the display mode has been specified by the input operation of the operation unit 16 (S6). If the first change unit 172 judges that the display mode has not been specified by the input operation of the operation unit 16 as a result of this judgment, the process returns to step S3, and the process continues from step S3. On the other hand, if the first change unit 172 judges that the display mode has been specified by the input operation of the operation unit 16 as a result of the judgment of step S6, the display mode (e.g., English) of the fire information displayed on the liquid crystal display unit 152 is changed to the display mode (e.g., Chinese) specified by the input operation of the operation unit 16 (S7). This allows the display mode (e.g., English) automatically changed in step S5 to be changed to a different display mode (e.g., Chinese) by the input operation of the operation unit 16. Then, the process returns to step S3, and the process continues from step S3.

(1.6) Main Effects The parent unit 1 (receiver) according to this embodiment is a receiver that receives a signal related to a fire (disaster prevention). The parent unit 1 includes a display unit 15 (user interface unit), an acquisition unit 171, and a first change unit 172. The display unit 15 is capable of displaying (outputting) fire information (information related to disaster prevention) based on the received signal. The acquisition unit 171 acquires user information related to the user who is using the parent unit 1. The first change unit 172 changes the display mode (output mode) of the display information (output information) displayed on the display unit 15 based on the user information acquired by the acquisition unit 171. This makes it possible to automatically change the display mode of the display information displayed on the display unit 15 according to the user.

(1.7) Modification (Modification 1)
In the first embodiment, the acquisition unit 171 is an imaging unit that captures an image including the user's face, but may be a device that acquires the user's biometric information (fingerprint, voiceprint, veins, iris, etc.). For example, when acquiring the user's fingerprint, the acquisition unit 171 is a fingerprint reader that reads the user's fingerprint. When acquiring the user's voiceprint, the acquisition unit 171 is a sound collector that collects the user's voice. When acquiring the user's veins (e.g., finger veins), the acquisition unit 171 is a vein reader that reads the user's veins. When acquiring the user's iris (e.g., pupil iris), the acquisition unit 171 is an iris reader that reads the user's iris.

(Variation 2)
In the first embodiment, the display mode is a type of language, but the display mode (output mode) may be a mode related to the restriction of the display information (output information). That is, the first change unit 172 may restrict the display information (output information) output from the liquid crystal display unit 152 (user interface unit) according to the user based on the user information. More specifically, the display information (output information) is composed of a plurality of pieces of information (element information), and each piece of element information is assigned an importance level. Each user registered in the parent unit 1 is associated with an importance level. The first change unit 172 displays (outputs) the element information corresponding to the importance level set by the user out of the display information (output information) on the liquid crystal display unit 152 based on the user information.

For example, if the liquid crystal display unit 152 is configured with a touch panel and the operation screen of the touch panel is displayed on the liquid crystal display unit 152 as display information, the contents of the operation screen may be made different depending on the importance corresponding to the user. This makes it possible to restrict the information accessible via the touch panel depending on the user.

Note that in this modified example, the output information is display information, but the output information is not limited to display information and may be information other than display information (e.g., audio information).

(Variation 3)
In the first embodiment, the user information may include the identification information of the user held by the entrance/exit management system that manages the entry and exit of the user. As shown in FIG. 5, in the above-mentioned entrance/exit management system, a user Q1 registered in the entrance/exit management system carries an ID tag 95 (information terminal) in which the identification information of the user Q1 is recorded. A reading device 90 is installed in one or more locations P1 (rooms, corridors, etc.) that are managed by the entrance/exit management system. The reading device 90 is a device for reading the identification information of the user Q1 from the ID tag 95 carried by the user Q1 who passes through the location P1 where the reading device 90 is installed. In the example of FIG. 5, a room is illustrated as an example of the location P1, and a case is illustrated in which the reading device 90 is installed near the entrance and exit of the room, and the master unit 1 is installed on an inner wall of the room.

When user Q1 passes through each location P1, the identification information on his/her ID tag 95 is read by a reading device 90 installed at that location P1. The entrance/exit management system includes a server that stores the identification information read by each reading device 90. The server is connected to each reading device 90 so that it can communicate with them. The entrance/exit management system manages the identification information stored in the server. This makes it possible for the entrance/exit management system to manage the actions of user Q1 (such as when and where the user was). The reading device 90 is an example of an identification information acquisition unit that acquires the identification information of user Q1.

As shown in FIG. 5, the parent unit 1 in this modified example is installed at a specified location P1, and is connected to a reading device 90 installed at the specified location P1 so as to be able to communicate data with the reading device 90. In this modified example, the reading device 90 at the location P1 where the parent unit 1 is installed reads the identification information of user Q1 from an ID tag 95 carried by user Q1, and transmits the read identification information to the parent unit 1. When the acquisition unit 171 of the parent unit 1 acquires the identification information of user Q1 from the reading device 90, the first change unit 172 of the parent unit 1 regards the user's identification information acquired by the acquisition unit 171 as user information. That is, in this modified example, the user information includes information obtained from the user's identification information.

Then, based on the acquired identification information, the first change unit 172 changes the display mode (e.g., language) of the display information displayed on the liquid crystal display unit 152 to a display mode corresponding to user Q1. As a result, for example, when user Q1 enters location P1 where parent unit 1 is installed, the reading device 90 reads his/her own identification information from his/her ID tag 95. Then, when user Q1 goes to parent unit 1, the display information displayed on the liquid crystal display unit 152 of parent unit 1 is automatically changed to a display mode corresponding to user Q1. Note that the dotted line in FIG. 5 shows an example of a travel route that user Q1 travels by passing through the reading device 90 and parent unit 1 in that order.

(2) Embodiment 2
(2.1) Overview This embodiment is different from the first embodiment in that a first change unit 174 is provided. The following description will focus on the differences from the first embodiment. Components similar to those in the first embodiment are denoted by the same reference numerals, and descriptions thereof will be omitted as appropriate.

In this embodiment, the first change unit 174 changes the display mode of the display information displayed on the display unit 15. In this embodiment, the display mode is, for example, the type of language (Japanese, English, Chinese, etc.) used in the display information.

In this way, since the parent unit 3 of this embodiment is equipped with the first change unit 174, the display mode (output mode) of the display information (output information) displayed (output) on the display unit 15 can be automatically changed according to the user. This makes it possible to change, for example, the language used in the display information displayed on the display unit 15.

(2.2) Configuration of parent unit 3 As shown in FIG. 6 , the parent unit 3 includes an application unit 11, a resistor 12, a transmission unit 13, a reception unit 14, a display unit 15 (user interface unit), an operation unit 16, a control unit 17, a memory unit 20, a standby power supply 18, and a communication interface (referred to as “communication I/F” in FIG. 1) 19.

The control unit 17 of this embodiment also includes a first change unit 174 that changes the display format (e.g., language) of the display information (e.g., fire information) displayed on the display unit 15.

The first change unit 174 changes the display mode of the display information displayed on the display unit 15 based on the input operation of the operation unit 16. More specifically, when a display mode is specified by the input operation of the operation unit 16, the first change unit 174 changes the display mode of the display information displayed on the display unit 15 to the display mode specified by the input operation of the operation unit 16.

In this embodiment, the display mode refers to the type of language (Japanese, English, Chinese, etc.) used in the display information displayed on the display unit 15. That is, in this embodiment, the display information displayed on the display unit 15 is stored in the memory unit 20 in multiple candidate modes (Japanese, English, Chinese, etc.). The user of the parent unit 3 selects one of the multiple candidate modes (Japanese, English, Chinese, etc.) and changes the display mode of the display information displayed on the display unit 15. This makes it possible to change to a display mode that corresponds to the user of the parent unit 3.

(2.3) Operation of the Master Unit 3 Next, the operation of the master unit 3 will be described with reference to Fig. 7. In the following description, a case where fire information is displayed on the display unit 15 of the master unit 3 as an example of display information will be illustrated.

When a fire breaks out, the receiver 14 of the parent unit 3 receives a fire alert from the detector 2 that detected the fire (S10). When the receiver 14 receives the fire alert, the control unit 17 of the parent unit 3 displays the fire information on the display unit 15 in the default display format (e.g., Japanese) (S11).

Then, the first change unit 174 judges whether or not the display mode has been specified by the input operation of the operation unit 16 (S12). If the first change unit 174 judges that the display mode has not been specified by the input operation of the operation unit 16 as a result of this judgment, the process returns to step S12, and the process continues from step S12. On the other hand, if the first change unit 174 judges that the display mode has been specified by the input operation of the operation unit 16 as a result of the judgment of step S12, the display mode of the fire information displayed on the display unit 15 (e.g., Japanese) is changed to the display mode (e.g., Chinese) specified by the input operation of the operation unit 16 (S13). Then, the process returns to step S12, and the process continues from step S12.

(2.4) Main Effects The parent unit 3 according to this embodiment is a receiver that receives signals related to a fire. The parent unit 3 includes a display unit 15 and a first change unit 174. The display unit 15 is capable of displaying fire information based on the received signal. The first change unit 174 changes the display mode of the display information displayed on the display unit 15. This makes it possible to change the display mode of the display information displayed on the display unit 15. For example, the parent unit 3 can be used even if there are multiple users, including a foreigner.

(3) Embodiment 3
(3.1) Overview In this embodiment, the parent unit 4 is different from the first and second embodiments in that it includes a second change unit 175. Below, the differences from the first and second embodiments will be mainly described, and the same components as those in the first and second embodiments will be denoted by the same reference numerals and descriptions thereof will be omitted as appropriate.

As shown in FIG. 8, the parent device 4 includes a second change unit 175. The second change unit 175 further changes the display mode changed by the first change unit 174 to a default display mode when a predetermined condition is satisfied.

Since the parent unit 4 of this embodiment is equipped with the second change unit 175, after the display mode (output mode) of the display information (output information) displayed (output) on the display unit 15 is changed by the first change unit 174, it can be further changed to the default display mode if a specified condition is satisfied.

As a result, even if, for example, the installer (user) of the parent unit 4 changes the language used in the display information displayed on the display unit 15 to English during construction, the language is further changed back to a default language (for example, Japanese) during operation, preventing the language from being forgotten to be changed back. Therefore, for example, it is possible to provide a parent unit 4 that can be used by both the installer performing the construction and the administrator performing the management, even if they primarily use different languages.

(3.2) Configuration of parent unit 4 As shown in FIG. 8 , the parent unit 4 includes the components of the parent unit 1 of embodiment 1, that is, an application unit 11, a resistor 12, a transmission unit 13, a reception unit 14, a display unit 15 (user interface unit), an operation unit 16, a control unit 17, a memory unit 20, a standby power supply 18, and a communication interface (referred to as “communication I/F” in FIG. 8 ) 19.

In this embodiment, the control unit 17 includes, in addition to the first change unit 174, a second change unit that further changes the display mode changed by the first change unit 174 to a default display mode when a predetermined condition is satisfied.

The second change unit 175 changes the display mode changed by the first change unit 174 to a default display mode when a predetermined condition is satisfied. In this embodiment, the display mode refers to the type of language (Japanese, English, Chinese, etc.) used in the display information displayed on the display unit 15, and multiple candidate modes (Japanese, English, Chinese, etc.) are stored in the memory unit 20. Here, the default display mode refers to a display language arbitrarily selected from multiple candidate languages, and it is preferable to select a language that can be understood by users who frequently use the management room of the building (apartment building A1) in which the master unit 4 is installed.

The second change unit 175 changes the display mode from the display mode changed by the first change unit 174 to the default display mode in response to a certain period of time during which the operation unit 16 is not operated after the first change unit 174 changes the display mode. In other words, the aforementioned "predetermined condition" refers to a certain period of time during which the operation unit 16 is not operated after the first change unit 174 changes the display mode.

With this configuration, if the parent unit 4 has not been operated for a certain period of time, the display mode can be automatically changed to the default display mode. In detail, for example, by setting the default display mode of the parent unit 4 to display in Japanese, even if the installer of the parent unit 4 changes the language used in the display information displayed on the display unit 15 to English during construction, the display will automatically be changed to Japanese, which is the default language, when the parent unit 4 is put into operation after a certain period of time has passed since construction.

In addition, without being limited to the above configuration, the second change unit 175 may change the display mode from the display mode changed by the first change unit 174 to the default display mode in response to the power being cut off after the first change unit 174 has changed the display mode. Here, "the power being cut off" includes a case where the user turns off the power of the parent unit 4, and also a case where power is no longer supplied to the parent unit 4 from the main power source such as a commercial power source or a private power generating facility due to a power outage at the facility.

With this configuration, the display mode can be automatically changed to the default display mode when the parent unit 4 is powered off.

Furthermore, after the first change unit 174 changes the display mode, the second change unit 175 may change the display mode to the default display mode in response to the parent unit 4 receiving a signal related to disaster prevention or crime prevention from the child unit 2.

With this configuration, the default display mode can be used reliably in the event of an emergency involving crime prevention or disaster prevention.

As described above, the second change unit 175 can prevent forgetting to change the language back by changing the display mode changed by the first change unit 174 to the default display mode when a predetermined condition is met. Therefore, it is possible to provide a parent unit 4 that can be used by both a contractor who performs construction and a manager who performs management, even if they primarily use different languages.

(3.3) Operation of the Master Unit 4 Next, the operation of the master unit 4 will be described with reference to Fig. 9. In the following description, a case where setting information during construction is displayed on the display unit 15 of the master unit 4 as an example of display information will be illustrated.

If the installer is a foreigner, the installer specifies a language that he or she can understand by inputting information into the operation section 16 of the master unit 4 when installing the automatic fire alarm system 100 including the master unit 4 (S20). The first change section 174 of the master unit 4 displays the setting information, which is information required for installation, in the display format (e.g., English) specified based on the inputting information (S21).

Then, the second change unit 175 judges whether or not a predetermined condition is satisfied (S22). Here, the "predetermined condition" includes, as described above, that a certain period of time has elapsed during which the operation unit 16 has not been operated, that the power supply to the master unit 4 has been cut off, and that the master unit 4 has received a disaster prevention or crime prevention signal from the slave unit 2.

If the second change unit 175 determines as a result of this determination that the predetermined condition is not satisfied, the process returns to step S21, and the process continues from step S21. On the other hand, if the second change unit 175 determines as a result of the determination in step S22 that the predetermined condition is satisfied, the display mode of the setting information changed by the first change unit 174 (e.g., English) is changed to the default display mode (e.g., Japanese) (S23). Then, the process returns to step S20, and the process continues from step S20.

(3.4) Main Effects The master unit 4 according to this embodiment is a receiver that receives signals related to a fire. The master unit 1 includes a display unit 15, a first change unit 174, and a second change unit 175. The second change unit 175 further changes the display mode of the display information displayed on the display unit 15, which has been changed by the first change unit, to a default display mode. This makes it possible to prevent forgetting to return the display mode of the display information displayed on the display unit 15 after changing it. Therefore, it is possible to provide a master unit 4 that can be used by both a contractor who performs construction and a manager who performs management, even if they primarily use different languages.

(4) Modifications The above embodiment is merely one of various embodiments of the present disclosure. The above embodiment can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. In addition, the same function as the control unit 17 of the parent units 1, 3, and 4 may be embodied as a control method, a computer program, or a non-transitory recording medium on which a computer program is recorded.

The control method according to one embodiment is a control method for a parent unit 1, 3, or 4 equipped with a display unit 15 capable of receiving a signal related to disaster prevention or crime prevention and outputting information related to disaster prevention or crime prevention based on the received signal. It includes acquiring user information related to a user who is using the parent unit 1, 3, or 4, and changing the display mode of the display information displayed on the display unit 15 based on the user information.

In one embodiment, the program causes a computer system to execute the above-mentioned control method.

(Variation 1)
In the first to third embodiments, the display mode is the type of language used in the display information. However, the display mode may also be the type of color (black, red, blue, etc.) of the characters used in the display information, or the type of thickness or size of the characters.

In this modified example, in the case of embodiment 1, the display information displayed on the display unit 15 is automatically changed in terms of the color, thickness, or size of the characters in response to the user. In the cases of embodiments 2 and 3, the display information displayed on the display unit 15 is automatically changed in terms of the color, thickness, or size of the characters in response to the user's input operation.

(Variation 2)
In the first to third embodiments, the user interface unit is the display unit 15 that displays display information (for example, fire information), but may also be an audio output unit that outputs output information (for example, fire information) by voice. In the first embodiment, the first change unit 172 changes the output mode of the output information output from the voice output unit based on the user information acquired by the acquisition unit 171. In the second and third embodiments, the first change unit 174 changes the output mode of the output information output from the voice output unit based on an input operation by the user. The output mode is the type of language (for example, Japanese, English, Chinese, etc.) used in the output information.

(Variation 3)
10, it is possible to display the same display information (output information) as that displayed on display 15 (first user interface unit) of parent unit 1 on display 62 (second user interface unit) of external terminal 60 carried by the user of parent unit 1. In other words, the user of parent unit 1 can view, on display 62 of the user's external terminal 60, the same display information as that displayed on display 15 of parent unit 1.

Although not shown in the figure, it goes without saying that the same modified example is also applicable to the second and third embodiments. In other words, the display unit 62 (second user interface unit) of the external terminal 60 carried by the user of the parent units 3 and 4 may be caused to display the same display information (output information) as the display information (output information) displayed on the display unit 15 (first user interface unit) of the parent units 3 and 4.

More specifically, the external terminal 60 has an information acquisition unit 61 and a display unit 62. The information acquisition unit 61 is a device that acquires specific information. The information acquisition unit 61 is, for example, a QR code reader that reads a QR code (registered trademark) as the specific information. The display unit 62 is a dot-matrix display unit that can display various information. The parent units 1, 3, and 4 of this modified example further include an information output unit 173 that outputs the specific information described above in the parent units 1, 3, and 4 of the above embodiment. The information output unit 173 includes, for example, a display unit that can display a QR code.

In this modified example, in the case of embodiment 1, the information output unit 173 generates modification information by changing the display mode of the display information that is the same as the display information displayed on the display unit 15, based on the user information acquired by the acquisition unit 171. In other words, the modification information is information in which the display mode of the display information displayed on the display unit 15 has been changed to a display mode corresponding to the user. Then, the information output unit 173 outputs the generated modification information as specified information.

In this modified example, when a user uses the parent unit 1 (for example, when viewing display information displayed on the display unit 15), the acquisition unit 171 of the parent unit 1 acquires user information related to the user using the parent unit 1. The information output unit 173 of the parent unit 1 generates the above-mentioned change information from the user information acquired by the acquisition unit 171 and the display information displayed on the display unit 15. The information output unit 173 then outputs the generated change information as specified information. The user then acquires the above-mentioned specified information output from the information output unit 173 of the parent unit 1 by the information acquisition unit 61 of the external terminal 60, generates change information from the acquired specified information, and displays it on the display unit 62 of the external terminal 60. That is, the information output unit 173 of the parent unit 1 outputs the specified information and has the information acquisition unit 61 of the external terminal 60 read it, thereby displaying the above-mentioned change information on the display unit 62 of the external terminal 60.

In the case of the second and third embodiments, the information output unit 173 generates modification information by changing the display mode of the same display information as the display information displayed on the display unit 15 based on the user's input operation. In other words, the modification information is information in which the display mode of the display information displayed on the display unit 15 has been changed to a display mode corresponding to the user's input operation. Then, the information output unit 173 outputs the generated modification information as the specified information.

In this modified example, when the user operates the operation unit 16 of the parent units 3 and 4, the information output unit 173 of the parent units 3 and 4 generates the above change information from the display information displayed on the display unit 15 based on the user's input operation. The information output unit 173 then outputs the generated change information as specified information. The user then acquires the above specified information output from the information output unit 173 of the parent units 3 and 4 using the information acquisition unit 61 of the external terminal 60, generates change information from the acquired specified information, and displays it on the display unit 62 of the external terminal 60. In other words, the information output unit 173 of the parent units 3 and 4 outputs the specified information and has the information acquisition unit 61 of the external terminal 60 read it, thereby displaying the above change information on the display unit 62 of the external terminal 60.

As a result, users of parent units 1, 3, and 4 can view the same display information displayed on display unit 15 of parent units 1, 3, and 4 on display unit 62 of the user's external terminal 60 in a display format that corresponds to the user.

(Variation 4)
In the above-mentioned third modification, the change information is directly transmitted and received between the base unit 1 and the external terminal 60. However, as shown in Fig. 11, the change information may be transmitted and received between the base unit 1 and the external terminal 60 via an external server 70.

Although not shown in the figure, it goes without saying that the same modified example is also applied to the second and third embodiments. In other words, the above change information is sent and received directly between the parent units 3 and 4 and the external terminal 60.

In this case, the parent units 1, 3, and 4 and the external terminal 60 are each connected to an external server 70 via a communication network (such as a public line network) in a wired or wireless manner so as to be able to communicate with the server 70. For example, the communication I/F 19 of the parent unit 1 functions as a communication unit for communicating with the server 70. The external terminal 60 has a communication unit 63 for communicating with the server 70. The server 70 stores, for each parent unit 1, various display information and various display modes possessed by the parent unit 1. The above various display information is stored in association with identification information for identifying each other. The above various display modes are stored in association with identification information for identifying each other. The above various display information and various display modes are, for example, transmitted from the parent units 1, 3, and 4 to the server 70 and stored in the server 70.

In the case of embodiment 1, the parent unit 1 outputs information including the first to fourth information as the above-mentioned specified information. The first information is identification information for identifying the parent unit 1. The second information is identification information for identifying the display information displayed on the display unit 15 of the parent unit 1. The third information is identification information for identifying the display mode corresponding to the user. The fourth information is information for identifying the location (address) of the server 70.

When the information acquisition unit 61 of the external terminal 60 acquires the above-mentioned specific information from the information output unit 173 of the parent unit 1, information specified by the first to third pieces of the above-mentioned specific information is acquired from the server 70 based on the acquired specific information (i.e., the first to fourth pieces of information), and is displayed on the display unit 62 of the external terminal 60. As a result, it is possible to display, on the display unit 62 of the external terminal 60 carried by the user of the parent unit 1, modified information that is the same display information as the display information displayed on the display unit 15 of the parent unit 1 but has been modified to a display mode corresponding to the user. This allows the user of the parent unit 1 to view, on the display unit 62 of the user's external terminal 60, the same display information as the display information displayed on the display unit 15 of the parent unit 1 in a display mode corresponding to the user.

In the case of the second and third embodiments, the parent units 3 and 4 output information including the first, second, and fourth information as the above-mentioned specific information. When the information acquisition unit 61 of the external terminal 60 acquires the above-mentioned specific information from the information output unit 173 of the parent units 3 and 4, the information specified by the first and second information of the above-mentioned specific information is acquired from the server 70 based on the acquired specific information (i.e., the first, second, and fourth information), and is displayed on the display unit 62 of the external terminal 60. As a result, it is possible to display the same display information as the display information displayed on the display unit 15 of the parent units 3 and 4 on the display unit 62 of the external terminal 60 carried by the user of the parent units 3 and 4. This allows the user of the parent units 3 and 4 to view the same display information as the display information displayed on the display unit 15 of the parent units 3 and 4 on the display unit 62 of the user's external terminal 60 in a display mode corresponding to the user.

(Variation 5)
In the first to third embodiments, the communication I/F 19 may be a communication unit that communicates with an external device using a wired or wireless communication network (e.g., a public line network, etc.). In this case, the first change units 172 and 174 operate based on a signal from the external device received via the communication I/F 19. More specifically, the first change units 172 and 174 change the display mode of the display information displayed on the display unit 15 to a display mode specified by the signal received from the external device based on the signal received from the external device. This makes it possible to control the first change units 172 and 174 of the parent units 1, 3, and 4 by a signal from the outside.

(Variation 6)
In the first to third embodiments, the present invention is applied to an automatic fire alarm system that receives a signal related to a disaster (disaster prevention), but may also be applied to an automatic crime prevention alarm system that receives a signal related to crime prevention.

(Other Modifications)
In the automatic fire alarm system 100 of the present disclosure, the control unit 17 of the parent unit 1, 3, 4, etc. includes a computer system. The computer system is mainly composed of a processor and a memory as hardware. The processor executes a program recorded in the memory of the computer system, thereby realizing the function of the control unit 17 of the parent unit 1 of the present disclosure. The program may be pre-recorded in the memory of the computer system, may be provided through an electric communication line, or may be recorded and provided in a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive that can be read by the computer system. The processor of the computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large scale integrated circuit (LSI). The integrated circuits such as IC or LSI here are called by different names depending on the degree of integration, and include integrated circuits called system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). Furthermore, a field-programmable gate array (FPGA) that is programmed after the manufacture of an LSI, or a logic device that allows reconfiguration of the connection relationship within the LSI or reconfiguration of the circuit partition within the LSI, can also be adopted as a processor. The electronic circuits may be integrated into one chip, or may be distributed among multiple chips. The chips may be integrated into one device, or may be distributed among multiple devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

Furthermore, it is not essential for the control unit 17 of the parent units 1, 3, and 4 to have multiple functions concentrated in one housing. In other words, the components of the control unit 17 may be distributed across multiple housings. Furthermore, at least some of the functions of the control unit 17 may be realized by the cloud (cloud computing) or the like.

In addition, the automatic fire alarm system 100 in the above embodiment is illustrated as being applied to a P-type automatic fire alarm system, but may also be applied to an R-type automatic fire alarm system.
