Description

The present invention relates to an operation confirmation aid for automatic fire alarm systems (hereinafter referred to as "fire alarms"), a fire alarm operation testing device, and a fire alarm operation testing method. More specifically, the present invention relates to a fire alarm operation confirmation aid, a fire alarm operation testing device, and a fire alarm operation testing method that allow a single user to efficiently perform fire alarm operation confirmation work, are easy to operate, and can be applied to fire receivers from various manufacturers with different specifications.

Japan's Fire Service Act (Article 17-3-3) requires buildings equipped with fire-fighting equipment to undergo twice-yearly inspections of the equipment (hereinafter referred to as "equipment inspections") and to report the results of the inspections to the local fire department (once a year for designated fire-prevention structures, and once every three years for non-designated fire-prevention structures; hereinafter referred to as "comprehensive inspections"). In particular, comprehensive inspections require that the overall functionality of the fire-fighting equipment be confirmed in accordance with standards set forth in public notices, depending on the type of fire-fighting equipment, by operating all or part of the equipment or using the equipment.

General inspections and equipment inspections (collectively referred to as "fire alarm operation check work") have generally been carried out by fire protection equipment engineers or qualified fire protection equipment inspectors. Traditionally, fire alarm operation check work has been carried out by at least two people, with one person working on the detector or alarm and testing it, while the other works on the fire receiver and checking whether the fire indicator light is illuminated. However, due to recent labor shortages and other factors, there have been cases where work has been delayed or workers have been overworked.

To solve the above problems, for example, a testing system has been proposed, as described in Patent Document 1 below. This testing system is capable of outputting test result information based on second test information corresponding to first test information output from the disaster prevention receiver. This allows a single worker to both output the alarm signal and check the test results, which is said to improve the efficiency of testing disaster prevention systems.

Patent No. 6510294

The test system described in Patent Document 1 is described as "triggering the display of first test information on the display means of the disaster prevention receiver to capture an image and transmit image information showing the captured image (specification paragraph 0016)," and the basic concept of the embodiment is described as "broadly speaking, the embodiment relates to a test system that, when first test information is output, transmits second test information based on the first test information, and outputs test result information showing the results of the disaster prevention system test based on the transmitted second test information (specification paragraph 0027)." Similar content is also described in specification paragraphs 0085-86.

In other words, the trigger for starting the test system can be said to be "the display of the first test information on the display means of the disaster prevention receiver," and an example of the first test information is information indicating that the indicator light 221 of the receiver 2 is lit.

However, the light interval of the indicator light of fire alarms can differ depending on the manufacturer; for example, Company A's indicator light may have a light interval of 1 second, while Company B's may have a light interval of 3 seconds. Furthermore, although this is not explicitly stated in Patent Document 1, given that the test system described therein was created by a fire alarm manufacturer, it is presumed that the light interval of the indicator light, which is the first test information, is based on that manufacturer's own standards. Therefore, a light interval of an indicator light according to another manufacturer's standards may not trigger the first test information for the test system, or may result in reduced detection accuracy.

In other words, the testing system described in Patent Document 1 is difficult to apply to fire alarms made by other manufacturers (i.e., other companies), and since the reliability of test results is expected to be reduced due to the possibility of reduced detection accuracy, it can be said that the system is difficult to use for those involved in inspecting fire alarms made by various manufacturers.

Furthermore, considering the specification of Patent Document 1, it is presumed that "indicator lights" refer to district indicator lights, and considering Figures 2 and 4 of Patent Document 1, it is clear that the receiver 2 is equipped with multiple indicator lights indicating districts. If all of the district indicator lights located above, below, left and right are to be photographed, it would be necessary to adjust the photographing area and confirm that all district indicator lights have been recognized for each test, making operation cumbersome.

Furthermore, for small-scale fire alarms with five or fewer circuits, there are "P-type Class 2 receivers" that do not have indicator lights, and the test system described in Patent Document 1 cannot be used for these.

The present invention was devised in light of the above points, and aims to provide a fire alarm operation confirmation aid, a fire alarm operation testing device, and a fire alarm operation testing method that allow a single user to efficiently perform fire alarm operation confirmation work, are easy to operate, and can be applied to fire receivers from various manufacturers with different specifications.

To achieve the above objective, the fire alarm operation confirmation aid of the present invention comprises: a take-out section, one end of which is attached to the fire alarm signal output terminal of a fire receiver; a detection section to which the other end of the take-out section is connected and which has a detection function capable of detecting fire alarm signals transmitted through the output terminal and a test signal transmission function that transmits a test signal generated when the detection function detects a fire alarm signal; a control section connected to the detection section and having a test signal reception function capable of receiving the test signal; an alarm start determination function that can determine whether an alarm should be started based on whether the test signal is detected; an alarm continuation determination function that determines whether an alarm should be continued based on the detection time of the test signal; and an audio output function that receives the determination results of the alarm start determination function and the alarm continuation determination function, and generates and outputs to an external device a sound notifying the user of the situation based on the determination results.

To use the fire alarm operation confirmation aid, first attach one end of the take-out section to the output terminal of the fire receiver. The fire receiver receives signals from the detector or alarm and emits a fire alarm signal to various pieces of equipment, such as security devices, via its output terminal. One end of the take-out section is connected to this output terminal, and the other end of the take-out section is connected to a detection section, which can use its detection function to detect the fire alarm signal emitted by the fire receiver and transmitted via its output terminal.

The "extraction unit" may be, for example, an electric wire, cord, cable, etc., with one end connectable to an output terminal and the other end connectable directly or indirectly to a fire alarm operation confirmation aid (detection unit). The "extraction unit" or "detection unit" may also be provided with a relay, photocoupler, or similar component, in which case a no-voltage signal can be extracted even if the output terminal is a voltage-applied contact.

The aforementioned one end is not particularly limited as long as it is a component or configuration that can be connected to the output terminal. For example, it may be configured such that a crimp terminal or the like is attached to the tip of a cord, or it may simply be configured such that the coating at the tip of the cord or the like is stripped off to allow current to flow.

With regard to the other end mentioned above, an example of one that is "directly connectable" is one whose other end is fixed to a fire alarm operation confirmation auxiliary device, while an example of one that is "indirectly connectable" is one whose other end is equipped with a connector, coupler, pin plug, etc. that can be connected to the fire alarm operation confirmation auxiliary device (detection unit) and is detachably attached to the fire alarm operation confirmation auxiliary device.

The detection unit has a test signal transmission function, which allows it to generate a test signal when it detects a fire alarm signal and transmit the test signal to the control unit. This "test signal" may be a signal of a different type other than a fire alarm signal converted from a fire alarm signal, or it may be a converted fire alarm signal itself.

The control unit connected to the detection unit has a test signal reception function, allowing it to receive test signals. The control unit has an alarm start determination function, allowing it to determine whether or not an alarm start is necessary based on whether or not a test signal is detected. More specifically, the alarm start determination function determines that an alarm start is necessary when a test signal is detected (detected), and determines that an alarm start is not necessary when a test signal is not detected (not detected).

The control unit has an alarm continuation determination function that allows it to determine whether or not to continue alarming based on the detection time of the test signal. More specifically, the alarm continuation determination function determines that alarming should continue when the test signal is detected for a predetermined time (detected), and determines that alarming should not begin (this can also be described as a "restored state") when the test signal is not detected for a predetermined time (not detected).

By having a voice output function, the control unit can generate and output to the outside a voice that notifies the user of the situation determined by the alarm start determination function and the alarm continuation determination function. More specifically, for example, an example of a "voice that notifies the user of the situation determined by the alarm start determination function" is "The fire indicator light has been activated," and an example of a "voice that notifies the user of the situation determined by the alarm continuation determination function" is "The alarm is continuing." However, this is not limited to these examples, and the voice may read out other words with a similar meaning.

The generated audio can be output externally via an audio output component connected directly or indirectly to the control unit so that it can be heard by the user. For example, an audio output component "directly connected to the control unit" may include a speaker or the like further provided inside or outside the control unit, and audio generated by the audio output function being output from the speaker or the like. An audio output component "indirectly connected to the control unit" may include a smartphone, tablet device, speaker, or the like capable of wireless communication further provided, and audio generated by the audio output function being transmitted as a wireless signal, and the signal received by the smartphone or the like being converted into audio and output.

As mentioned above, fire alarm operation confirmation work was previously performed by at least two people in pairs. However, with the fire alarm operation confirmation aid of the present invention, which is equipped with the above-mentioned configuration, the user is responsible for activating the detector or alarm, and the fire receiver receives the fire alarm transfer signal, and the user can check whether the fire alarm transfer signal has been sent to each piece of equipment, such as security devices, via the output terminal by listening to the audio generated by the fire alarm operation confirmation aid. This eliminates the need for dedicated personnel to check whether the fire alarm transfer signal has been sent at the fire receiver's installation location. In other words, a single user can perform the fire alarm operation confirmation work.

As mentioned above, some small-scale fire alarms with five or fewer circuits do not have indicator lights, and specifications such as the presence or absence of fire indicator lights vary depending on the manufacturer. However, almost all manufacturers' fire receivers are equipped with a fire alarm signal output terminal. The fire alarm operation confirmation aid of the present invention utilizes the fire alarm signal output terminal equipped on almost all manufacturers' fire receivers. The detection unit detects the fire alarm signal passing through the output terminal, a test signal is generated upon detection of the fire alarm signal, and the control unit determines the start and continuation of the alarm based on the received test signal. This makes it applicable to fire receivers from various manufacturers with different specifications, including existing, relatively older models of fire receivers, making it highly versatile. Furthermore, the fire alarm operation confirmation aid of the present invention has a simple structure in which the removal unit is simply attached to the fire alarm signal output terminal on the fire receiver, making it easy to operate and highly convenient to use.

Furthermore, if the aforementioned fire alarm operation confirmation auxiliary device has at least one output terminal, either a buzzer terminal for the auxiliary receiver or a district bell terminal, the fire alarm signal can be extracted from these output terminals. These terminals often have a voltage of 24V DC (24 volts direct current), and a relay unit (relay, photocoupler, etc.) is installed at the "extraction unit" or "between the extraction unit and the detection unit." It is also preferable to install a photocoupler to further improve insulation.

Furthermore, if the aforementioned fire alarm operation confirmation auxiliary device has at least one output terminal, either a fire representative terminal or a signal transfer terminal, the fire signal can be extracted from these output terminals. Furthermore, these terminals are often voltage-free, which eliminates the need for the aforementioned "relay section," making the structure simpler and more convenient.

Furthermore, if the aforementioned fire alarm operation confirmation aid further includes a use date and time determination unit connected to the control unit, and the use date and time determination unit has a first date and time acquisition function that acquires the date and time when use began, a second date and time acquisition function that acquires any date and time after use began, and a date calculation function that calculates the difference between the results of the first date and time acquisition function and the second date and time acquisition function, it can accommodate usage methods with limited time or date and time.

For example, the fire alarm operation confirmation aid of the present invention is suitable for use when rented out for use for a limited time or period (hereinafter referred to as "rental use"). The usage date and time determination unit acquires the date and time when use began using the first date and time acquisition function, acquires any date and time after use began using the second date and time acquisition function, and calculates the difference between the results of the first date and time acquisition function and the second date and time acquisition function using the date calculation function. This allows the owner of the fire alarm operation confirmation aid of the present invention to manage the period of use and, for example, to collect a usage fee from the person who rented it out based on the period of use.

Furthermore, if the aforementioned fire alarm operation confirmation aid further comprises a usability determination unit that cooperates with the use date and time determination unit, and the usability determination unit has a usability determination function that cooperates with the use date and time determination unit to determine usability, and a usability stop function that stops the operation of the control unit based on a signal from the usability determination function, it can determine whether the fire alarm operation confirmation aid is usable and stop its use after a certain time or date has passed. This can deter unauthorized use when renting.

The aforementioned fire alarm operation confirmation aid also includes an external key interface connected to the control unit, and the external key interface has a storage medium connection unit capable of accepting a storage medium serving as an external key storing the activation permission password for the control unit, an authentication function that reads the storage medium connected to the storage medium connection unit and authenticates the validity of the activation permission password stored on the storage medium, and a password transmission function that transmits the activation permission password authenticated by the authentication function to the control unit. If the control unit has a password processing function that receives the activation permission password, cancels the usage suspension function, and enables the control unit to be used, the storage medium storing the activation permission password can be used to restrict whether the control unit can be activated. This can deter unauthorized use in rental applications and further improve the convenience of the aid.

To achieve the above objective, the fire alarm operation testing device of the present invention comprises: a fire alarm operation confirmation aid having a take-out section, one end of which is attached to the fire alarm signal output terminal of a fire receiver; a detection section to which the other end of the take-out section is connected and which has a detection function capable of detecting fire alarm signals transmitted through the output terminal and a test signal transmission function that transmits a test signal when the detection function detects a fire alarm signal; a test signal reception function connected to the detection section and capable of receiving the test signal; an alarm start determination function that can determine whether an alarm should be started based on whether the test signal is detected; an alarm continuation determination function that determines whether an alarm should be continued based on the detection time of the test signal; and an audio output function that receives the determination results of the alarm start determination function and the alarm continuation determination function, generates audio notifying the user of the situation based on the determination result, and outputs the audio to an external device; and a mobile communication terminal that has the function of capturing video including audio and the function of transmitting the captured video and audio, and is positioned so that the fire alarm operation confirmation aid and the fire receiver to which it is attached can be photographed.

To use the fire alarm operation testing device, first attach one end of the take-out portion of the fire alarm operation confirmation aid to the output terminal of the fire receiver. As mentioned above, the fire receiver emits a fire alarm signal via the output terminal. One end of the take-out portion is connected to this output terminal, and the other end of the take-out portion is connected to a detection unit that can use its detection function to detect the fire alarm signal emitted by the fire receiver and transmitted via the output terminal.

The detection unit has a test signal transmission function, which allows it to generate a test signal when it detects a fire alarm signal and transmit the test signal to the control unit. This "test signal" may be a signal of a different type other than a fire alarm signal converted from a fire alarm signal, or it may be a converted fire alarm signal itself.

The control unit connected to the detection unit has a test signal reception function, allowing it to receive test signals. The control unit has an alarm start determination function, allowing it to determine whether or not an alarm start is necessary based on whether or not a test signal is detected. More specifically, the alarm start determination function determines that an alarm start is necessary when a test signal is detected (detected), and determines that an alarm start is not necessary when a test signal is not detected (not detected).

The control unit has an alarm continuation determination function that allows it to determine whether or not to continue alarming based on the detection time of the test signal. More specifically, the alarm continuation determination function determines that alarming needs to continue when the test signal is detected for a predetermined time (detected), and determines that a recovery state has occurred when the test signal is not detected for a predetermined time (not detected).

By having an audio output function, the control unit can generate and output to the outside a sound notifying the user of the situation determined by the alarm start determination function and the alarm continuation determination function. The generated sound can be output to the outside via a sound output component connected directly or indirectly to the control unit so that it can be heard by the user.

The mobile communication terminal has the aforementioned imaging and transmission functions, and by positioning the fire alarm operation confirmation aid so that it can capture video and activating it, it is possible to transmit video of the fire alarm's operating status and the audio generated by the fire alarm operation confirmation aid to an external device.

The fire alarm operation test device of the present invention allows a user to receive and observe video and audio transmitted from a mobile communication terminal related to the fire alarm operation test device on another mobile communication terminal they have on hand. This allows a single user to perform the fire alarm operation check work, which previously required at least two people working together.

Furthermore, the fire alarm operation testing device of the present invention is configured so that the aforementioned fire alarm operation confirmation auxiliary device detects the fire alarm signal passing through the output terminal in the detection unit, generates a test signal upon detection of the fire alarm signal, and determines the start and continuation of the alarm in the control unit based on the received test signal. Therefore, it can be applied to fire receivers of various manufacturers with different specifications, including existing relatively old fire receivers and small fire alarms with five or fewer circuits that do not have indicator lights, making it highly versatile. Furthermore, the fire alarm operation testing device of the present invention has a simple structure in which the extraction unit is simply attached to the fire alarm signal output terminal of the fire receiver, making it easy to operate and highly efficient to work with.

In order to achieve the above-mentioned objectives, the method for testing the operation of a fire alarm of the present invention is carried out using a fire alarm operation confirmation aid having a removal section, a detection section connected to the removal section, and a control section connected to the detection section, a transmitting mobile communication terminal having a photographing function and a function for transmitting photographed video and audio, and a receiving mobile communication terminal having a function for receiving video and audio photographed and transmitted by the transmitting mobile communication terminal. The method comprises the following steps: a first step: placing the fire alarm operation confirmation aid on the fire receiver of the fire alarm; attaching the removal section to one end of the fire receiver's fire alarm signal output terminal and activating the control section; and positioning the transmitting mobile communication terminal so that it can photograph the fire alarm operation confirmation aid and the fire receiver; a second step: activating a detector or alarm constituting the fire alarm for testing purposes; and a second step: using the detection function of the detection section to detect the fire alarm signal transmitted via the output terminal in response to a signal from the detector or alarm, and transmitting a test signal using the detection section's test signal transmission function. The system comprises: a third step of transmitting a test signal generated when the detection function detects a fire alarm transfer signal; a fourth step of receiving the test signal using the test signal receiving function of the control unit, determining whether to start an alarm based on whether the test signal is detected using the alarm start determination function of the control unit, determining whether to continue an alarm based on the detection time of the test signal using the alarm continuation determination function of the control unit, and generating and outputting to the outside using the audio output function of the control unit audio notifying the situation based on the determination results received from the alarm start determination function and the alarm continuation determination function; a fifth step of photographing the fire alarm operation confirmation aid and the fire receiver using the imaging function of the transmitting mobile communication terminal and transmitting the captured video and audio using the transmitting function; and a sixth step of receiving the video and audio transmitted from the transmitting mobile communication terminal at the receiving mobile communication terminal, allowing the user to view the video and audio to confirm the operation of the fire receiver.

The user attaches one end of the fire alarm operation confirmation aid to the fire receiver's fire alarm signal output terminal and activates the control unit, thereby attaching the fire alarm operation confirmation aid to the fire receiver and positioning the transmitting mobile communication terminal, and is ready to photograph the fire alarm operation confirmation aid and fire receiver (first step). This eliminates the need for personnel to be stationed in front of the fire receiver.

Then, the detector or alarm is activated and the test begins (second step). At this time, a user who activates the detector or alarm with a heating appliance or smoke generating appliance only needs to be present at the location of the detector or alarm.

The fire receiver receives a signal from the detector or alarm and transmits a fire alarm transfer signal to each piece of equipment, such as a security device, via its output terminal. At this time, the fire alarm operation confirmation aid extracts the fire alarm transfer signal via an extraction unit connected to the output terminal, and the detection unit connected to the extraction unit can detect the fire alarm transfer signal via the fire receiver's output terminal using its detection function. The detection unit then generates and transmits a test signal using its test signal transmission function when it detects a fire alarm transfer signal (third step). Furthermore, the control unit of the fire alarm operation confirmation aid receives the test signal, determines whether to start an alarm, determines whether to continue an alarm, and generates and outputs a sound to notify the user of the situation based on the determination result (fourth step).

The transmitting mobile communication terminal captures a video of the fire alarm operation confirmation aid and the fire receiver, and transmits the captured video and audio (step 5). The receiving mobile communication terminal then receives the video and audio transmitted from the transmitting mobile communication terminal, and the user watches and listens to the video and audio to confirm the operation of the fire receiver (step 6).

The fire alarm operation test method of the present invention, which includes the steps described above, allows a user to receive and observe the video and audio transmitted from the transmitting mobile communication terminal on a receiving mobile communication terminal held by the user. This allows a single user to perform the fire alarm operation check, which previously required a team of at least two people.

Furthermore, by using the aforementioned fire alarm operation confirmation aid, the fire alarm operation test method of the present invention can be applied to fire receivers from various manufacturers with different existing specifications, making it highly versatile. Furthermore, the fire alarm operation test method of the present invention is easy to operate and has good workability, as the fire alarm operation confirmation aid used has a simple structure in which the aforementioned extraction part is simply attached to the fire alarm transfer signal output terminal on the fire receiver.

Although it is common to perform the second step after the first step, it is also possible to perform the second step before the first step. In other words, the first and second steps do not necessarily have to be performed in numerical order, and the order in which they are performed can be reversed.

The present invention provides a fire alarm operation confirmation aid, a fire alarm operation testing device, and a fire alarm operation testing method that allow a single user to efficiently perform fire alarm operation confirmation work, are easy to operate, and can be applied to fire receivers from various manufacturers with different specifications.

Embodiments of the present invention will be described in more detail with reference to Figures 1 to 7. The following description will be given in the order of [First Embodiment], [Variation 1], [Variation 2], [Second Embodiment], and [Variation 3]. Furthermore, the reference numerals in each drawing are assigned to the extent necessary to reduce complexity and facilitate understanding, and in some cases, the same reference numeral may be assigned to only some of the equivalent parts.

First Embodiment
[Fire alarm operation test device 1]
The fire alarm operation test device 1 includes a fire alarm operation check aid 2 and a transmitting portable communication terminal 3 (see FIG. 1).

(Fire alarm operation confirmation aid 2)
The fire alarm operation confirmation aid 2 has a removal section 20, a detection section 21, and a control section 22 (see FIGS. 1 and 2). A casing 202 is provided with a casing attachment section 203 (see FIGS. 1 and 2(a)). Each section will be described in detail below.

The extraction unit 20 has two cores, a cable 200 of a predetermined length split into two at the tip, and a crimp terminal 201 attached to the tip of the cable 200, the base end of which is connected to the detection unit 21. The crimp terminal 201 is attached to the output terminal of the fire detector 5, which will be described later.

In this embodiment, the crimp terminal 201 is an open-end terminal (also known as a Y terminal), but this is not limited to this. For example, it may be a round terminal (also known as an R terminal or ring terminal) or a flat connection terminal (also known as a plate-shaped terminal, etc.).

The casing 202 is a hollow steel box that contains the detection unit 21, the test signal receiving function part 223, the alarm start determination function part 224, the alarm continuation determination function part 225, the audio output function part 226, and the power supply part 227.

The casing mounting portion 203 is a leg-like portion that protrudes toward the side of the casing 202 when the fire alarm operation confirmation aid 2 is installed, and has a magnet (not shown) at the position opposite the casing 202 (tip portion).

Detection unit 21 is connected to the base end of cable 200 and has a detection function that can detect a fire alarm signal transmitted via the output terminal, and a test signal transmission function that generates a test signal when the detection function detects a fire alarm signal (see Figure 2(b)). The test signal transmission function is configured to generate a test signal when the detection function detects a fire alarm signal transmitted via the output terminal and transmit the test signal to control unit 22.

(Control unit 22)
The control unit 22 is connected to the detection unit 21, and has a test signal receiving function part 223, an alarm start determination function part 224, an alarm continuation determination function part 225, an audio output function part 226, and a power supply part 227 (see FIG. 2(b)). Note that the test signal receiving function part 223, the alarm start determination function part 224, the alarm continuation determination function part 225, and the audio output function part 226 are structures that are realized by using an integrated circuit such as a microcomputer or a program installed in the integrated circuit.

The test signal receiving function portion 223 corresponds to the "test signal receiving function" described above and is capable of receiving test signals.

The alarm start determination function part 224 corresponds to the "alarm start determination function" described above, and is connected to the test signal receiving function part 223 so that it can determine whether or not an alarm start is required based on whether or not a test signal received via the test signal receiving function part 223 is detected.

The alarm continuation determination function part 225 corresponds to the "alarm continuation determination function" described above, and is connected to the test signal receiving function part 223 so that it can determine whether or not to continue the alarm based on the detection time of the test signal received via the test signal receiving function part 223.

The audio output function part 226 corresponds to the "audio output function" described above, and is connected to the alarm start determination function part 224 and the alarm continuation determination function part 225. It is configured to receive the determination results of the alarm start determination function part 224 and the alarm continuation determination function part 225, and generate and output to the outside audio notifying the situation based on the determination results. The audio output function part 226 has an audio generation function (not shown) and an audio output function that has a speaker part (not shown).

The power supply unit 227 is a storage battery that supplies power to the various parts of the detection unit 21 and control unit 22 that require power as needed.

(Sending portable communication terminal 3)
The transmitting mobile communication terminal 3 is a smartphone that has the function of shooting video including audio and transmitting the video and audio. The transmitting mobile communication terminal 3 is also positioned on a tripod so that it can shoot the fire alarm operation confirmation aid 2 and the fire receiver 5 to which it is attached (see Figure 1).

In this embodiment, the casing mounting portion 203 has the above-described arrangement and shape, but is not limited to this. For example, it may have a shape other than a strip, and may be provided at any one or more locations near the periphery of the casing 202. Furthermore, this does not exclude the possibility of it being located on the same side as the cable 200.

In this embodiment, the casing 202 is made of steel, but this is not limited to this and may be made of a material with a certain rigidity that can protect the contents, such as plastic or carbon.

In this embodiment, the casing mounting portion 203 has the configuration described above, but is not limited to this. For example, it may be located on the bottom or mounting surface of the casing when the fire alarm operation confirmation aid 2 is installed, or the entire bottom surface of the casing or a portion thereof may serve as the casing mounting portion. Furthermore, the casing mounting portion may be replaced with a fixing means other than a magnet (for example, an adhesive or suction cup), and this does not exclude configurations that do not have a fixing means such as a magnet.

In this embodiment, the power supply unit 227 is a storage battery, but this is not limited to this and may be, for example, a primary battery or external power.

In this embodiment, the transmitting mobile communication terminal 3 is a smartphone, but is not limited to this. For example, it could be a tablet device or a personal computer with a camera, or it could be a dedicated device with at least the ability to shoot video including audio and the ability to transmit the captured video and audio. Also, a tripod is used as the member for placing the transmitting mobile communication terminal 3, but is not limited to this. For example, it could be a fixed stand, a fixed frame, or any other known member.

[Functions and effects of each part of the fire alarm operation test device 1 including the fire alarm operation confirmation auxiliary device 2, and the fire alarm operation test method]
With reference to Figures 1 to 4, the effects of each part of the fire alarm operation testing device 1, including the fire alarm operation confirmation auxiliary device 2, will be explained, and a method for testing the operation of a fire alarm, which includes a first step S1, a second step S2, a third step S3, a fourth step S4, a fifth step S5, and a sixth step S6 shown in Figure 3, will be explained.

<First step S1>
In the first step, the fire alarm operation confirmation aid 2 is placed on the fire receiver 5 of the fire alarm, the crimp terminal 201 (i.e., one end of the extraction part 20) is attached to the output terminal 51 of the fire receiver 5 (either or both of the fire representative terminal 511 or the signal transfer terminal 512), and the control part 22 is started. Then, the transmitting portable communication terminal 3 is placed so that it can photograph the fire alarm operation confirmation aid 2 and the fire receiver 5, thereby completing preparations to photograph the fire alarm operation confirmation aid 2 and the fire receiver 5. In other words, the first step can also be described as a pre-work preparation process.

In addition, if necessary, stop the main sound system (the buzzer built into the fire receiver), stop the local sound system (bells installed in hallways, etc.), stop the transmission of alerts from linked devices (such as to security companies), change the test recovery switch to test recovery mode, and disable the storage function.

Here, the test recovery switch refers to a functional switch that releases the self-holding function of the fire detector during an operational test and automatically restores it. The accumulation function accumulates the set time (in other words, the accumulation period) from when the detector detects heat or smoke until it rings the bell. Even if a fire signal is received from the detector, there is a possibility of a false alarm, so the signal is held for a certain period of time, and if the signal continues to be received, the bell or siren will sound. By disabling the accumulation function, the fire light will come on when the detector detects a fire.

The photographing range of the transmitting mobile communication terminal 3 does not necessarily have to be the entire fire alarm operation confirmation aid 2 or the entire fire receiver 5, but it is preferable that it includes at least the fire indicator light (and the district indicator light, if installed).

Incidentally, many fire alarm receivers 5 have a front door or front display panel made of steel. For this reason, when placing the casing 202 of the fire alarm operation confirmation aid 2, the casing mounting portion 203, which has the aforementioned structure, can be magnetically attached to the front door of the fire alarm receiver 5, etc. This eliminates the need for a long connection cord 215, improving ease of handling.

Furthermore, when photographing the fire alarm operation confirmation aid 2 and fire receiver 5 with the transmitting mobile communication terminal 3, if the fire alarm operation confirmation aid 2 is far from the fire receiver 5, the distance between them and the transmitting mobile communication terminal 3 must be long. If the fire receiver 5 is installed in a small room where this distance is short, it may be difficult to photograph with the transmitting mobile communication terminal 3. However, with the fire alarm operation confirmation aid 2, the device can be placed close to the fire receiver 5, so the fire alarm operation confirmation aid 2 and fire receiver 5 can be photographed with the transmitting mobile communication terminal 3 even from a relatively short distance.

<Second step S2>
After completing the first step, the user moves to the location of the detector or alarm that is the target of the operation test, activates the detector or alarm, and starts the test. In this test, the user carries the receiving mobile communication terminal 4 that can communicate with the sending mobile communication terminal 3.

<Third step S3>
After the test starts, the fire alarm operation confirmation aid 2 receives a signal from the detector or alarm, and the detection unit 21 detects the fire alarm signal transmitted to each piece of equipment such as a security device via its output terminal 51. More specifically, the detection unit 21 detects the fire alarm signal extracted via the extraction unit 20 using the detection function, generates a test signal, and transmits the generated test signal to the control unit 22 using the test signal transmission function (see S3 "Yes" in FIG. 4). Note that if the detection function does not detect the fire alarm signal, the test signal is not generated or transmitted to the control unit 22 (see S3 "No" in FIG. 4).

In addition, the output terminals 51 (either the fire representative terminal 511 or the signal transfer terminal 512, or both) used in the fire alarm operation confirmation auxiliary device 2 are often voltage-free, eliminating the need for relays, photocouplers, or other relays, thereby simplifying the structure.

<Fourth step S4>
The control unit 22 receives the test signal, determines whether or not it is necessary to start an alarm, determines whether or not it is necessary to continue the alarm, and generates and outputs a sound to notify the situation based on the determination result. More specifically, the control unit 22 receives the test signal transmitted by the test signal receiving function part 223, and transmits the test signal to the alarm start determination function part 224 and the alarm continuation determination function part 225 connected to the test signal receiving function part 223.

The alarm start determination function part 224 determines whether an alarm start is necessary based on whether the received test signal is detected, and if the determination result is "necessary," it sends an "alarm start necessary" signal to the audio output function part 226 (see S4 "Yes" in Figure 4). The audio output function part 226 receives the determination result of the alarm start determination function part 224 (the "alarm start necessary" signal), generates audio notifying the situation based on the determination result (for example, "The fire indicator light has activated an alarm"), and outputs this audio externally.

If the determination result of the alarm start determination function part 224 is "no alarm start (unnecessary)," no signal is generated and transmitted to the audio output function part 226 (see S4 "No" in Figure 4).

The alarm continuation determination function part 225 determines whether or not it is necessary to continue the alarm based on the detection time of the received test signal, and transmits a signal indicating "continue alarming" or "not necessary to continue alarming" (see S4 "Yes" in Figure 4). When the audio output function part 226 receives the determination result of the alarm continuation determination function part 225 (a "continue alarming" signal), it generates an audio message (e.g., "The fire is continuing") notifying the user of the situation based on the determination result, and outputs the audio message externally.

When the determination result of the alarm continuation determination function part 225 is "No alarm continuation (unnecessary)," the audio output function part 226 generates and outputs to the outside as audio (for example, "The fire indicator light has been restored") notifying the situation based on the determination result when the first "No alarm continuation (unnecessary)" determination result is received (see S4 "Yes" in Figure 4), and when the second or subsequent "No alarm continuation (unnecessary)" determination result is received, no signal is generated and no signal is sent to the audio output function part 226 (see S4 "No" in Figure 4).

<Fifth step S5>
The transmitting mobile communication terminal 3 photographs the fire alarm operation confirmation aid 2 and the fire receiver 5, and transmits the photographed video and audio. This transmission is preferably performed using a wireless communication method that does not require wiring (Internet line, wireless LAN, Wi-Fi, etc.), but wired communication is not excluded. The photographed video and audio can also be transmitted using a relay function provided in the transmitting mobile communication terminal 3, a relay application (live streaming application) installed on the transmitting mobile communication terminal 3, or the like.

<Sixth step S6>
The user receives the video and audio transmitted from the transmitting mobile communication terminal 3 on the receiving mobile communication terminal 4 that the user possesses, and checks the operation of the fire receiver 5 by viewing the video and audio.

In the second step, the user activates the detector or alarm to begin the test, and in the sixth step, if the user can confirm that a fire alarm transfer signal (test signal) has been issued through the video and audio received and viewed on the receiving mobile communication terminal 4, the user can determine that the fire alarm is functioning normally.

On the other hand, if the user activates the detector or alarm in step 2 to start the test, but is unable to confirm the issuance of a fire alarm signal (test signal) from the video and audio received and viewed on the receiving mobile communication terminal 4 in step 6, a malfunction in one of the parts of the fire alarm (including the detector or alarm, or fire receiver 5) is suspected.

Note that while the receiving mobile communication terminal 4 used here is a smartphone, it is not limited to this and could also be, for example, a tablet device or a personal computer. Furthermore, in this embodiment, the video and audio transmitted from the transmitting mobile communication terminal 3 are viewed on the receiving mobile communication terminal 4, but the video and audio could also be recorded on a server, or the user's superior administrator could share and monitor the video and audio information.

<Effects of the fire alarm operation test device 1>
As explained in the first step S1, when using the fire alarm operation testing device 1, first, the crimp terminal 201 of the fire alarm operation confirmation aid 2 is attached to the output terminal 51 of the fire receiver 5. As explained in the second step S2 to the third step S3, the detection unit 21, which has a detection function and a test signal transmission function, transmits a test signal to the control unit 22 when it detects a fire alarm transfer signal.

As explained in the fourth step S4, after receiving the test signal, the control unit 22 determines whether or not to start an alarm based on whether or not the test signal is detected using the alarm start determination function part 224, and determines whether or not to continue the alarm based on the detection time of the test signal using the alarm continuation determination function part 225. Then, the control unit 22 generates and outputs to the outside using the audio output function part 226 an audio signal notifying the user of the status determined by the alarm start determination function part 224 and the alarm continuation determination function part 225.

The transmitting mobile communication terminal 3 transmits video footage of the operation status of the fire alarm 5 and audio generated by the fire alarm operation confirmation aid 2.

The casing 202, with its aforementioned configuration, protects the detection unit 21 and control unit 22 contained therein from shocks that may occur during transportation or handling. Furthermore, the power supply unit 227 uses a storage battery, which means that it can be used without a nearby outlet, making it easier to handle than devices powered by external sources. Furthermore, this ease of handling also makes it possible to attach the fire alarm operation confirmation aid 2 near the fire receiver 5.

As described above, the fire alarm operation testing method using the fire alarm operation testing device 1 including the fire alarm operation confirmation aid 2 includes the steps described above, allowing the user to receive video and audio transmitted from the transmitting mobile communication terminal 3 on the receiving mobile communication terminal 4 held by the user, and observe the operating status of the fire alarm 5.

This allows a single user to check the operation of a fire alarm, something that previously required a team of at least two people. In other words, the user who activates the detector or alarm with a heating appliance or smoke generator only needs to be located in the location of the detector or alarm. There is no need to station personnel in front of the fire control receiver 5, allowing the work to be performed with a minimum number of people.

By the way, fire alarm receivers are often installed in nurse centers in hospitals, offices in hotels, and matron rooms in nursing homes. In the past, when fire alarm operation tests were conducted, the person in charge of monitoring the fire alarms would stay in these rooms for long periods of time (sometimes as long as half a day).

In contrast, the use of the fire alarm operation testing device 1 and fire alarm operation testing method of the present invention eliminates the need for a fire alarm monitor (leaving the fire alarm unmanned), which is expected to have the following effects: preventing the introduction of infectious diseases (COVID-19, influenza, etc.), alleviating labor shortages by saving labor, maintaining confidentiality and preventing information leaks, reducing operation testing costs by keeping labor costs down, and reducing the distraction of the monitoring staff (who may be perceived as a hindrance to work from the facility's perspective) (in other words, it is particularly suitable for work in buildings or spaces where the entry of large numbers of people is undesirable from the perspective of privacy protection, security management, infection prevention, etc.).

Furthermore, because fire alarms typically have an output terminal, the fire alarm operation confirmation aid 2 can be used with fire receivers from different manufacturers. In other words, because the control unit 22 is designed to determine the start and continuation of an alarm based on the fire alarm transfer signal detected by the fire alarm operation confirmation aid 2, it can be applied to existing fire receivers from various manufacturers with different specifications, making it highly versatile. Furthermore, the fire alarm operation confirmation aid 2 has a simple structure that allows operation confirmation tests to be performed simply by attaching the removal unit 20 to the output terminal 51, making it easy to operate and highly efficient.

[Variation 1]
Please refer to Fig. 5. The fire alarm operation confirmation aid 2a shown in Fig. 5 is a modified example of the fire alarm operation confirmation aid 2, in which a relay unit 204 (relay, photocoupler, etc.) is provided inside the casing 202 between the base end of the cable 200 of the extraction unit 20 and the detection unit 21.

In this modified example, the crimp terminal 201 is connected to one of the output terminals 51, either the auxiliary receiver buzzer terminal 513 or the district bell terminal 514. This allows the fire alarm signal to be extracted from either the auxiliary receiver buzzer terminal 513 or the district bell terminal 514. Even if the auxiliary receiver buzzer terminal 513 or the district bell terminal 514 (output terminal) is a voltage-applied contact, the relay unit 204 allows the signal to be extracted without voltage.

As a further modification, the fire alarm operation confirmation aid 2a in this modified example may have a cable separate from the cable 200 of the extraction unit 20 shown in Figure 5, which is connected directly to the detection unit 21 without going through the relay unit 204 (not shown).

In this case, cable 200 is installed in conjunction with another cable, and as mentioned above, cable 200 can be connected to the fire representative terminal 511 or the signal transfer terminal 512, while this other cable can be connected to the sub-receiver buzzer terminal 513 or the district bell terminal 514. This means that a single unit can be used with a variety of output terminals 51, improving convenience.

The configuration of this modified example can also be applied to the fire alarm operation confirmation aids described in Modification 2 and the second embodiment onwards, which will be described later, and the same effects and advantages can be achieved by applying them.

[Variation 2]
As a modified example, the fire alarm operation confirmation aid 2 may be provided with an audio output terminal (not shown) connected to the audio output function part 226 in the control part housing part 221 of the control part 22. Then, the other end (audio input terminal) of the audio cord inserted into the audio output terminal (not shown) is connected to the audio terminal of the transmitting mobile communication terminal 3.

As a result, the fire alarm operation confirmation aid 2 and the transmitting mobile communication terminal 3 are connected by wire, and sound is not output directly from the fire alarm operation confirmation aid 2 to the outside of the device, so sound generated by the fire alarm operation confirmation aid 2 can be suppressed in the vicinity where the fire alarm operation confirmation aid 2 is installed.

In addition, because the sound generated by the sound output function section 226 is input directly to the transmitting mobile communication terminal 3, mixing of the sound generated in the vicinity of the fire alarm operation confirmation aid 2 and the sound picked up by the transmitting mobile communication terminal 3 is suppressed, ensuring that the sound heard by the receiving mobile communication terminal 4 is clear and preventing the user from mishearing the sound.

The configuration of this modified example can also be applied to the fire alarm operation confirmation aid described in the second embodiment and beyond, and the same effects and advantages are achieved by applying it.

Second Embodiment
(Fire alarm operation confirmation aid 2b)
6, a fire alarm operation confirmation aid 2b, which is a second embodiment of the fire alarm operation confirmation aid 2, will be described. Note that only the structure and effects that differ from the fire alarm operation confirmation aid 2 will be described, and descriptions of other common parts will be omitted, and common parts will be assigned the same numbers in the drawings. The fire alarm operation confirmation aid 2b has a detection unit 21 and a control unit 22b (see FIG. 6). Since the detection unit 21 is common to the fire alarm operation confirmation aid 2, description thereof will be omitted.

(Control unit 22b)
The control unit 22b has a casing 202, a casing attachment portion (not shown), a test signal receiving function portion 223, an alarm start determination function portion 224, an alarm continuation determination function portion 225, an audio output function portion 226, a power supply portion 227, a use date and time determination portion 229, and a usability determination portion 230 (see FIG. 6). Note that the casing 202, the casing attachment portion, the test signal receiving function portion 223, the alarm start determination function portion 224, the alarm continuation determination function portion 225, the audio output function portion 226, and the power supply portion 227 are common to the fire alarm operation confirmation auxiliary device 2, and therefore a description of the configuration and effects will be omitted.

The usage date and time determination section 229 and the usability determination section 230 correspond to the "usage date and time determination unit" and "usability determination section" described above, and are structures realized by using an integrated circuit such as a microcomputer or a program installed on the integrated circuit.

The usage date and time determination unit 229 has a first date and time acquisition function that acquires the date and time when usage began, a second date and time acquisition function that acquires any date and time after usage began, and a date calculation function that calculates the difference between the first date and time acquisition function and the second date and time acquisition function. The usage date and time determination unit 229 is combined with GPS to obtain the first date and time acquisition function and the second date and time acquisition function, but is not limited to this. For example, it may be combined with a radio-controlled clock to receive JJY radio waves.

In the usage date and time determination unit 229, the first date and time acquisition function acquires the date and time when usage began, the second date and time acquisition function acquires any date and time after usage began, and the date calculation function calculates the difference between the results of the first date and time acquisition function and the second date and time acquisition function.

The usability determination section 230 has a usability determination function that determines usability in cooperation with the use date and time determination section 229, and a usage stop function that stops the operation of the control section 22b based on a signal from the usability determination function. The usability determination section 230 determines whether the fire alarm operation confirmation auxiliary device 2b can be used, and can stop its use if a certain time or date has passed.

The usability determination section 230 is also directly connected to the audio output function section 226, and the usability determination section 230 determines whether the device is usable and sends a signal indicating the determination result to the audio output function section 226. If the signal indicates that the device is usable, the audio output function section 226 generates a sound notifying the user of the situation based on the determination result (for example, "This device is usable") and outputs the sound externally. On the other hand, if the signal indicates that the device is not usable, the audio output function section 226 generates a sound notifying the user of the situation based on the determination result (for example, "This device is not usable") and outputs the sound externally.

The use date and time determination section 229 and usability determination section 230 of the control section 22b achieve the above-mentioned effects, allowing the owner of the fire alarm operation confirmation aid 2b to manage the usage period of the fire alarm operation confirmation aid 2b to those to whom it is rented, making it easy to collect usage fees based on the usage period and further preventing unauthorized use for rental purposes.

[Variation 3]
In the fire alarm operation confirmation aid 2b', the control unit 22b' may further include an external key interface section 231 (see FIG. 7). The external key interface section 231 corresponds to the above-mentioned "external key interface section," is connected to the usability determination section 230, and includes a storage medium connection section (not shown), an authentication function (not shown), and a password transmission function (not shown).

The storage medium connection portion is configured to accept a memory card (corresponding to the storage medium described above) that stores the startup permission password for the control unit 22b'. The authentication function is configured to read the memory card connected to the storage medium connection portion and authenticate the validity of the startup permission password stored on the memory card. The password transmission function is configured to transmit the startup permission password authenticated by the authentication function to the availability determination portion 230 of the control unit 22b'. The availability determination portion 230 then has a password processing function that receives the startup permission password, cancels the usage suspension function, and enables the control unit 22b' to be used.

In the fire alarm operation confirmation aid 2b' of Variation 3, a restriction is placed on whether the control unit 22b' can be activated, and an activation permission password is used to lift the restriction. The owner of the fire alarm operation confirmation aid 2b' also lends a memory card storing the activation permission password to the person to whom the aid is rented. In other words, the person to whom the fire alarm operation confirmation aid 2b' is rented needs both the fire alarm operation confirmation aid 2a and the memory card to use it, which serves as a deterrent to unauthorized use when renting and further improves the convenience of the fire alarm operation confirmation aid 2b'.

In this modified example, a memory card is used, but this is not limited to this and other storage media such as USB memory may also be used. Also, in this modified example, the storage media connection part is a memory card slot, but this is not limited to this and the shape and structure of the storage media connection part can be modified as appropriate to match the shape of the connection part for other storage media such as USB memory.

The terms and expressions used in this specification and claims are for explanatory purposes only and are not intended to exclude terms and expressions equivalent to the features described in this specification and claims, or portions thereof. It goes without saying that various modifications are possible within the scope of the technical concept of the present invention. Furthermore, terms such as "first," "second," etc., do not imply rank or importance, but are used to distinguish one element from another.
