Description

TECHNICAL FIELD The present invention relates to an alarm system that performs interlocking alarms by installing a plurality of alarm devices that detect and alarm fires by grouping them.

2. Description of the Related Art Conventionally, an alarm device that detects and warns a fire in a house or the like has been widely used. Among them, the residential fire alarm is called the residential alarm. For example, such a residential alarm operates on a battery power supply, and is equipped with a sensor unit that detects fire and an alarm unit that alarms fire. When a fire is detected, the alarm unit outputs a fire alarm sound, and unlike so-called automatic fire alarm equipment, a receiver or the like is not required. It is also inexpensive in terms of cost, and has become widely used due to the compulsory installation in general houses.

In addition, by performing mutual wireless communication between a plurality of fire alarms, when a fire alarm sound is output by an arbitrary fire alarm, other fire alarms are also interlocked to output a fire alarm sound Wireless interlocking An alarm system using a type of residential alarm has also been put into practical use and is in widespread use.

In addition, for specific small facilities with a floor area of less than 300 square meters, which are not obligated to install fire alarm equipment, such as group homes that provide housekeeping support for the elderly and intellectually disabled, automatic fire alarm systems for specific small facilities A fire alarm system has been installed. The automatic fire alarm system for specified small-scale facilities consists of detectors that integrate a sensor unit that detects fires and an alarm unit that warns of fires. When the fire is detected, all the detectors in the facility are triggered to inform the entire facility of the fire.

Hereinafter, detectors used in wireless interlocking residential alarms and automatic fire alarm equipment for specific small-scale facilities will be referred to as interlocking alarms.

In such an interlocking alarm system, when a fire is detected by an interlocking alarm, the interlocking alarm that detected the fire will say, for example, "Woo-woo fire alarm has been activated. Please check." While outputting a fire alarm sound and turning on the alarm display LED, on the other hand, the interlocking alarm device outputs a fire alarm sound such as "Woo woo another fire alarm has been activated. The display LED blinks.

However, in such a conventional wireless interlocking alarm system, when one interlocking alarm device receives a radio signal from another interlocking alarm device, a plurality of radio signals using the same communication frequency are used. may arrive at the same time and cause a signal collision. Limited number of units.

In order to solve this problem, when forming a group consisting of a plurality of interlocked alarms, the maximum number of interlocked alarms is set so that the frequency of signal collision does not increase, and multiple groups formed in this way An alarm system has been proposed in which a repeater is arranged between the groups so that they are interlocked, and the communication frequency used is different for each group (Patent Document 1).

In this group-linked alarm system, by linking a plurality of groups within a warning area, the total number of linked alarm devices can be increased, and the communication frequency of the linked alarm device differs depending on the group. Therefore, even if a signal from an interlocked alarm device in a certain group and a signal from an interlocked alarm device in another group arrive at the same time, signal collision does not occur and signals can be transmitted and received. can be done reliably.

This problem of signal collision is the same in systems that do not distinguish between the parent and child units of interlocking alarms when using wireless signals, and in parent-child systems in which multiple child units are arranged for the parent unit. In the case of the parent-child method, for example, the parent device uses the individual ID of each child device to sequentially call and process the child devices. Communication takes time. Therefore, in order to reduce the frequency of signal collision with the parent device, the number of child devices is limited to a predetermined maximum number or less to form a group, and the parent device of each group is provided with a relay function to work together. The alarm system uses different communication frequencies for

For this reason, the alarm system, which is larger than a general house and consists of ordinary wireless interlocking residential alarms, cannot cover the entire area due to the limitation on the maximum number of alarms. By installing an alarm system that works with groups in facilities that operate simple lodgings under the Inns and Hotels Act and specified small-scale facilities, it is possible to avoid the problem of signal collision and increase the number of interlocking alarm devices throughout the facility. By increasing the number to a sufficient level, it is possible to provide a fire monitoring function equivalent to installing a fire alarm system at a low cost.

However, in an alarm system that performs such group interlocking, group interlocking is performed for groups within the range in which the alarm system is installed, and it is impossible to perform interlocking by a specific group for all groups. It's not necessarily good, and it can cause unnecessary confusion depending on the cohesive content and the situation of each group.

Also, in addition to the wireless communication function with the interlocking alarm device, it is conceivable to use multiple alarm transfer adapters that are capable of inputting and outputting alarm signals to function as repeaters, but use the alarm transfer adapter Depending on the setting of the notification from the transfer adapter, it may be difficult to recognize the notification in the case of the repeater, which may cause unnecessary confusion in this case as well.

SUMMARY OF THE INVENTION An object of the present invention is to provide an alarm system in which an inter-group alarm device, which is an alarm device and a repeater, is controlled so that persons in an area where the alarm system is installed are not unnecessarily confused. do.

[Outline of alarm system]
FIG. 1 is an explanatory diagram showing an embodiment of an alarm system arranged in a building with a hierarchical structure.
As shown in FIG. 1, the alarm system of the present embodiment is installed, for example, in a four-story building 11 such as a private lodging facility. In each security area, for example, five wireless interlocking interlocking alarms 10 functioning as alarms are installed.

Here, five interlocking alarm devices 10 installed on the 1st to 4th floors constitute groups G1, G2, G3, and G4, as shown on the left side of the building 11. Groups G1, G2, and G3 , G4 are assigned different channel frequencies f1, f2, f3, and f4, and the interlocking alarm devices 10 of each group G1 to G4 use the channel frequencies f1 to f4 assigned to their own groups. to transmit and receive signals.

The interlocked alarm devices 10 provided in groups G1 to G4 output a fire alarm indicating the interlocking source when a fire is detected, and transmit a fire interlocking signal to the other interlocked alarm devices 10 in their own group. to output a fire alarm indicating the interlocking destination.

Inter-group alarm transfer devices 12-12, 12-23 and 12-34 are installed between the groups G1 to G4 corresponding to the security areas on each floor of the building 11. FIG. The inter-group alarm transfer devices 12-12, 12-23, 12-34 enable transmission and reception of signals between both interlocked alarm devices 10 provided in groups on adjacent floors. It is installed on the wall of the landing of the stairs connecting the

A first report transfer adapter 14 and a second report transfer adapter 16 are incorporated in the inter-group report transfer devices 12-12, 12-23 and 12-34.

For example, taking the inter-group alarm device 12-12 installed between the group G1 on the 1st floor and the group G2 on the 2nd floor as an example, the first alarm transfer adapter 14 has an interlocking alarm device for the group G1 on the 1st floor. The same channel frequency f1 as 10 is set, and various signals including fire interlocking signals are transmitted and received with the interlocking alarm devices 10 of group G1 installed on the first floor.

In addition, the second alarm transfer adapter 16 is set to the same channel frequency f2 as the interlocked alarm device 10 of group G2 on the 2nd floor, and the interlocked alarm device 10 of group G2 installed on the second floor Sends and receives various signals including fire interlocking signals.

The first report transfer adapter 14 and the second report transfer adapter 16 incorporated in the inter-group report transfer device 12-12 are provided with a transfer input terminal and a transfer output terminal. The report transfer input terminal of the second report transfer adapter 16 is connected by internal wiring, and the report transfer output terminal of the second report transfer adapter 16 is connected to the report transfer input terminal of the first report transfer adapter 14 by internal wiring. there is

When the first report transfer adapter 14 incorporated in the inter-group report transfer device 12-12 receives the fire interlocking signal of the channel frequency f1 from the interlocked alarm device 10 belonging to its own group G1, the second report transfer adapter 16 outputs a fire alarm signal. The second alarm transfer adapter 16, which has received the fire alarm transfer signal from the first alarm transfer adapter 14, transmits the fire interlocking signal of the channel frequency f2 to the interlocking alarm device 10 in its own group G2, and selects the interlocking destination. to output the indicated fire alarm.

Further, when the second alarm transfer adapter 16 incorporated in the inter-group alarm transfer device 12-12 receives the fire interlocking signal of the channel frequency f2 from the interlocked alarm device 10 belonging to its own group G2, the first transfer adapter 16 A fire alarm signal is output to the information adapter 14 . The first alarm transfer adapter 14, which has received the fire alarm transfer signal from the second alarm transfer adapter 16, transmits the fire interlocking signal of the channel frequency f1 to the interlocking type alarm device 10 in its own group G1 to select the interlocking destination. to output the indicated fire alarm.

The functions of the first information transfer adapter 14 and the second information transfer adapter 16 are the same for the inter-group information transfer devices 12-23 and 12-34, except that the channel frequencies used are different.

Therefore, the channel frequency f2 of the group G2 is set to the first information transfer adapter 14 of the inter-group information transfer device 12-23, and the channel frequency f3 of the group G3 is set to the second information transfer adapter 16. FIG.

In addition, the channel frequency f3 of group G3 is set to the first information transfer adapter 14 of the inter-group information transfer device 12-34, and the channel frequency f4 of group G4 is set to the second information transfer adapter 16. FIG.

Here, the communication route of the fire interlocking signal between the groups G1 to G4 is, for example, when the interlocking alarm 10 of the group G1 detects a fire, the interlocking alarm 10 of the group G1, Alarm transfer device 12-12, interlocked alarm device 10 of group G2, inter-group alarm transfer device 12-23, inter-group alarm device 10 of group G3, inter-group alarm transfer device 12-34 and interlocked alarm device of group G4 10, and the inter-group alarm transfer devices 12-12, 12-23, 12-34 are sent from the interlocked alarm device 10 of the group G1, and the inter-group alarm transfer devices 12-12, 12-23, There is a second route from 12-34 to the interlocked alarms 10 of each group G2, G3, G4.

As shown in FIG. 1, inter-group signal transfer devices 12-12, 12-23, and 12-34 are arranged on a stair landing or the like, and if adjacent devices can transmit and receive signals wirelessly, Communication is performed by two routes. On the other hand, when the inter-group information transfer devices 12-12, 12-23, and 12-34 are far from each other's communicable area, communication follows the first route. In addition, it is assumed that the first route and the second route are used for mixed communication.

[Function configuration of interlocking alarm]
FIG. 2 is a block diagram showing the functional configuration of the interlocking alarm device. As shown in FIG. 2, the interlocking alarm 10 is composed of an interlocking alarm control unit 18, a communication unit 20 having an antenna 22, a sensor unit 24, an operation indicator lamp 26, a speaker 28, and an alarm stop switch 30. , operates on a battery power supply (not shown).

The interlocking alarm controller 18 is composed of a computer circuit having a CPU, memory, and various input/output ports.

The communication unit 20 sets one of the four channel frequencies f1, f2, f3, f4 in the 400 MHz band, for example, the channel frequency f1, based on the instruction from the interlocked alarm control unit 18 based on the initial settings. , and other interlocking alarm devices 10 belonging to the same group can transmit and receive signals wirelessly.

The communication unit 20 has a configuration conforming to STD-30 (low-power security system radio station radio equipment standard) known as a standard for specified low-power radio stations in the 400 MHz band in Japan, for example. . Of course, for places other than Japan, the communication unit 20 will have contents conforming to the standard of the assigned radio station in that area.

The sensor unit 24 is provided with a smoke detection unit, which detects a fire when the smoke caused by the fire reaches a predetermined concentration. In addition to the smoke detection unit, a temperature detection element such as a thermistor for detecting temperature due to fire, or various elements for detecting changes in other physical phenomena due to fire may be provided.

The operation indicator lamp 26 indicates an abnormality such as a fire by blinking, lighting, blinking, etc. of the LED based on the instruction from the interlocking alarm controller 18 . Alternatively, a two-color LED or two LEDs with different display colors may be provided so that the display of the interlocking source and the display of the interlocking destination are displayed in different colors.

The speaker 28 outputs a voice message and an alarm sound by voice synthesis based on instructions from the interlocking alarm controller 18 .

The alarm stop switch 30 also functions as an inspection switch, and an alarm stop instruction can be input only when the alarm sound of the speaker 28 and the alarm display of the operation indicator lamp 26 are being performed. When the stop switch 30 is operated, a function check is performed and the result is reported.

The control functions of the interlocked alarm control unit 18 are realized by executing a program, and have the following control functions.

When the interlocking alarm control unit 18 detects a fire based on the smoke detection signal from the smoke detection unit provided in the sensor unit 24, the interlocking alarm control unit 18 emits an alarm sound indicating the interlocking source from the speaker 28. Please check." is repeatedly output, and control is performed such that the operation indicator lamp 26 is turned on, for example, to output an alarm indicating the interlocking source.

Further, the interlocking alarm device control unit 18 controls transmission of a fire interlocking signal from the communication unit 20 to other interlocking alarm devices using the channel frequency f1 when a fire is detected.

Further, when the communication unit 20 receives a fire interlocking signal of channel frequency f1 from another interlocking alarm device, the interlocking alarm control unit 18 outputs an alarm sound indicating the interlocking destination from the speaker 28, for example, "Woo woo another fire The alarm has been activated. Please check." is repeatedly output, and at the same time, the operation indicator lamp 26 is flashed, for example, to output a fire alarm indicating the interlocking destination.

In addition, when the interlocking alarm control unit 18 detects an alarm stop operation of the alarm stop switch 30 during the output of a fire alarm or failure alarm, the interlocking alarm control unit 18 groups a control/alarm stop interlocking signal for stopping the alarm sound from the speaker 28. control to transmit to other interlocking alarm device 10 in.

Furthermore, the interlocking alarm controller 18 performs communication tests, battery voltage drop monitoring, and circuit failure monitoring. When a communication error, battery voltage drop, or circuit failure is detected, a predetermined fault alarm A sound is output, the operation indicator lamp 26 is flashed to output a failure alarm, and a failure interlocking signal is transmitted from the communication unit 20 to other interlocking alarm devices using the channel frequency f1. .

[Functional configuration of inter-group signal transfer device]
FIG. 3 is a block diagram showing the functional configuration of the inter-group information transfer device, taking as an example the inter-group information transfer device 12-12 installed between the group G1 on the 1st floor and the group G2 on the 2nd floor of FIG. , and other inter-group information transfer devices 12-23 and 12-34.

As shown in FIG. 3, the inter-group report transfer device 12-12 has a first report transfer adapter 14 and a second report transfer adapter 16 in one device housing. The difference is that the channel frequency f1 of the group G1 is set to the first information transfer adapter 14 and the channel frequency f2 of the group G2 is set to the second information transfer adapter 16, but other configurations and functions are the same. , will be essentially the same.

The first report transfer adapter 14 includes an adapter control section 32, a communication section 34 to which an antenna 36 is connected, an operation indicator lamp 42, a speaker 44, a test switch 46, a report transfer output section 38 connected to a report transfer output terminal 38a, It is composed of a report input unit 40 connected to a report input terminal 40a, and operates with a battery power supply (not shown). The second information transfer adapter 16 also has the same configuration.

The report input terminal 40a and the report output terminal 38a may be configured as a connector structure that is gripped when wiring is inserted. Also, the antenna 36 may be built in the case of the transfer adapter.

The inter-group report transfer device has a panel door that can be opened and closed on the front of a box-shaped device housing that opens to the front. The structure is visible.

The report transfer output terminal 38a of the first report transfer adapter 14 is connected to the report transfer input terminal 40a of the second report transfer adapter 16 by an internal wiring 48, and the report transfer input terminal 40a of the first report transfer adapter 14 is connected to An internal wiring 50 from the report transfer output terminal 38a of the second report transfer adapter 16 is connected.

The information transfer output unit 38 of the first information transfer adapter 14 outputs a non-voltage contact signal by connection with the information transfer input unit 40 on the second information transfer adapter 16 side and the internal wiring 48 . That is, the report transfer input unit 40 of the second report transfer adapter 16 applies a power supply voltage to one of the internal wirings 48 via a pull-up resistor, and the report transfer output unit 38 of the first report transfer adapter 14 A non-voltage contact that is turned on by the operation of the relay is connected between the internal wirings 48 .

When the first report transfer adapter 14 outputs a report signal, the relay operates to turn on the no-voltage contact of the report output unit 38 to supply a current to the internal wiring 48, and the second report transfer adapter 16 inputs the transfer signal. The voltage across the internal wiring seen from the unit 40 drops to approximately zero volts, and the voltage drop in the internal wiring 48 is detected to detect the input of the fire signal. Similarly, the information transfer output unit 38 of the second information transfer adapter 16 and the information transfer input unit 40 of the first information transfer adapter 14 input and output contactless voltage signals.

The adapter control unit 32 is composed of a computer circuit having a CPU, memory, and various input/output ports.

The communication unit 34 is the same as the communication unit 20 provided in the interlocked alarm device 10 of FIG. In Japan, for example, it is known as the standard for specified low-power radio stations in the 400 MHz band. It has a configuration that complies with STD-30 (low-power security system radio station radio equipment standard).

The operation indicator lamp 42 displays a fire alarm, a failure alarm, etc. by blinking, lighting, blinking, etc. of the LED based on an instruction from the adapter control unit 32 . The speaker 44 outputs voice messages and warning sounds by voice synthesis based on instructions from the adapter control unit 32 . The test switch 46 performs operations such as alarm stop, communication test, report transfer stop, and report transfer stop release.

The control function of the adapter control unit 32 of the first information transfer adapter 14 is realized by executing a program, and has the following control functions.

When the adapter control unit 32 of the first report transfer adapter 14 receives the fire interlocking signal of the first channel frequency f1 from the interlocked alarm device 10 of its own group G1, the adapter control unit 32 operates the report transfer output unit 38 to perform the second Control is performed to output a fire report signal to the report transfer adapter 16 .

The adapter control unit 32 of the second report transfer adapter 16, which has detected the input of the fire report signal from the first report transfer adapter 14, instructs the communication unit 34 to send the fire interlocking signal of the channel frequency f2 set to the group G2. is transmitted to the interlocked alarm device 10 in its own group G2 to output a fire alarm indicating the interlocked destination.

Further, when the adapter control section 32 of the first report transfer adapter 14 detects the input of the fire report signal from the second report transfer adapter 16, it instructs the communication section 34 to transmit the fire interlocking signal of the channel frequency f1 to its own. Control is performed to output a fire alarm that is transmitted to the interlocked alarm device 10 in the group G1 and indicates the interlocked destination.

In addition, when the adapter control unit 32 of the first alarm transfer adapter 14 receives the fire interlocking signal from the interlocking alarm device 10 in its own group G1, the speaker 44 says, "Woooo! The fire alarm has been activated. Please control to repeatedly output the alarm sound "Please, please" and at the same time to output the fire alarm by flashing the operation indicator lamp 42, for example. It should be noted that the fire alarm to be issued by the first alarm adapter 14 may be displayed only by the operation indicator lamp 42 without outputting an alarm sound.

Further, when the adapter control unit 32 of the first alarm transfer adapter 14 receives the alarm stop interlocking signal from the interlocked alarm device 10 in its own group G1 during the fire alarm or failure alarm, the fire transfer adapter 14 control to stop alarms and failure alarms.

In addition, the adapter control unit 32 of the first report transfer adapter 14 receives a failure interlocking signal transmitted by detecting a communication failure, failure, or battery voltage drop in the interlocking alarm device 10 in its own group G1. In this case, a voice message indicating the details of the failure is output from the speaker 44, and the action of blinking the operation indicator lamp 42 a predetermined number of times is repeated at predetermined time intervals to output a failure alarm.

Such a control function of the adapter control section 32 is the same as that of the adapter control section 32 of the second information transfer adapter 16 .

Also, the first alarm transfer adapter 14 that receives the fire interlocking signal from the interlocking alarm device 10 in its own group G1 outputs the fire alarm and the fire alarm signal of the second alarm transfer adapter 16, but the fire transfer The second alarm transfer adapter 16 that receives the alarm signal transmits the fire interlocking signal to the interlocking alarm device 10 in its own group G2, but may not perform alarm operation.

Such an alarm operation of the alarm transfer adapter 14 is the same when the second alarm transfer adapter 16 receives the fire interlocking signal from the interlocking alarm device 10 in its own group G2.

If the first report transfer adapter 14 and the second report transfer adapter 16 give alarms at the same time, the sounds are mixed and it becomes difficult to hear. avoid that.

Also, the second report transfer adapter 16 may receive a fire interlocking signal of channel frequency f2 set for group G2 transmitted from the adjacent inter-group report transfer device 12-23 shown in FIG. In this case, the adapter control section 32 of the second report transfer adapter 16 operates the report transfer output section 38 to control outputting the fire report signal to the first report transfer adapter 14 .

When the adapter control unit 32 of the first report transfer adapter 14 detects the input of the fire report signal from the second report transfer adapter 16, it instructs the communication unit 34 to detect the fire of the channel frequency f1 set to the group G1. The interlocking signal is transmitted to the interlocking alarm device 10 in its own group G1, and control is performed to output the interlocking destination fire alarm.

In this way, the transfer of the fire interlocking signal via the inter-group alarm transfer devices 12-12, 12-23, 12-34 does not include communication via the interlocking alarm device 10 of each group. It is possible to interlock the fire alarm of, for example, the group G4, which is the farthest from the group G1 in which a fire has been detected, in a shorter communication time.

[Control operation of the transfer adapter]
FIG. 4 is a flow chart showing the control operation of the report transfer adapter device incorporated in the inter-group report transfer device. For example, the description is as follows.

As shown in FIG. 4, the adapter control unit 32 of the first information transfer adapter 14 selects the channel frequency f1 of the group G1 assigned to itself by a predetermined registration operation or the like in the initial setting in step S1 when the battery power is turned on. is set.

Subsequently, when the adapter control unit 32 determines in step S2 that the fire interlocking signal with the channel frequency f1 transmitted from the interlocking alarm device 10 in its own group G1 is received, the process proceeds to step S3, and the alarm output unit 38 outputs the 2. A fire alarm signal is output to the alarm transfer adapter 16, and then, in step S4, a fire alarm is output by the alarm sound from the speaker 44 and the operation of the operation indicator lamp 42. FIG.

Further, when the adapter control section 32 determines in step S5 that the fire report input section 40 has input the fire report signal from the second report transfer adapter 16, the process proceeds to step S6, where it instructs the communication section 34 to select its own group G1. Then, in step S7, the alarm sound from the speaker 44 and the action of the operation indicator light 42 cause the fire alarm to be output.

Further, when the adapter control unit 32 determines in step S8 that the alarm stop interlocking signal from the interlocking alarm device 10 of its own group is received via the communication unit 34, the process proceeds to step S9, where the fire alarm is being issued or the failure alarm is being issued. If it is determined that it is inside, the process proceeds to step S10 to stop the fire alarm.

Further, when the adapter control unit 32 determines in step S11 that the failure interlocking signal has been received from the interlocking alarm device 10 of its own group via the communication unit 34, the process proceeds to step S12, and an alarm sound and an operation indicator light are emitted from the speaker 44. Activation of 42 causes a fault alarm to be output.

[Group channel frequency setting]
FIG. 5 is an explanatory diagram showing another embodiment of an alarm system arranged in a building with a hierarchical structure. As shown in FIG. 5, the alarm system of the present embodiment targets a six-story building 11, divides it into groups according to the floors of 1F to 6F, and arranges a plurality of interlocked alarm devices 10, and each group Group-to-group signal transfer devices 12-12, 12-23, 12-34, 12-45, and 12-56 are arranged on the landings of the stairs that serve as boundaries.

Allocation of channel frequencies f1 to f4 of groups G1 to G4 of 1F to 4F in this embodiment is the same as in the embodiment of FIG. , and 6F is assigned a group G2 in which the same channel frequency f2 as that of 2F is set.

Here, the interlocked alarm device 10 installed in each group has a limit in its communicable distance. It does not reach the alarm 10.

In this way, even if the interlocked alarm devices 10 set to the same channel frequency f1 are installed in the 1F and 5F, which are the warning areas that are separated beyond the communication area of the interlocked alarm device 10, signals are sent to each other. Since it is not possible to send and receive, there is no problem of interference. This point is the same between 2F and 6F.

Therefore, in this embodiment, 1F and 5F, which are separated from each other beyond the communicable area of the interlocked alarm device 10, are grouped into group G1, and the same channel frequency f1 is set. The frequency f2 is set, and even if the number of interlocked groups increases, the number of channel frequencies to be set can be reduced without causing interference.

[Modification of the present invention]
Although the above embodiment does not distinguish between the interlocking signal by the mobile adapter and the interlocking signal by the interlocking alarm device, the interlocking signal by the mobile adapter and the interlocking signal by the interlocking alarm device may be distinguished. Regarding the method of distinguishing, it is possible to distinguish by using the device type or device-specific identification information included in the interlocking signal, or when setting the interlocking alarm and the alarm transfer adapter in the same group, transfer as an address within the group. The data adapter may be made to use a fixed in-group address.

Further, by distinguishing the interlocking signals, the fire interlocking signal by the alarm transfer adapter and the fire interlocking signal by the interlocking type alarm device may be distinguished. The fire interlocking signal from the alarm transfer adapter is the fire interlocking signal from the alarm transfer adapter that received the fire alarm signal. can be identified by the interlocking alarm device that receives the information, and the contents of the alarm can be differentiated. For example, it is possible to give an alarm such as ``Woo-woo, another group's fire alarm has been activated.'' This makes it possible to grasp the urgency of the fire and how to respond.

Further, in the above-described embodiment, by not transferring failures between report transfer adapters, failures in interlocked alarm devices are prevented from being alarmed by interlocked alarm devices in different groups. , and from the transfer adapter to which the fault was transferred, a fault interlocking signal that can be distinguished from the fault interlocking signal of the interlocking alarm device is transmitted. Alternatively, a report transfer adapter different from the one that transmitted the failure interlocking signal may receive the failure interlocking signal and perform an operation to warn of the failure. As a result, while the interlocking alarm does not warn of a failure in another group, the relay operation of the group is possible by the report transfer adapter, so it is possible to check whether a failure has occurred just by looking at the report transfer adapter. will be understood.

Also, in the report transfer adapter, it is possible to distinguish whether the fault interlocking signal is from the interlocking type alarm device or from the report transfer adapter, and to give different alarms at the time of fault. As a result, it becomes possible to distinguish between the interlocked alarm device in the group where the failure occurred and the interlocked alarm device that was transferred, and it is possible to check which group the failure occurred by simply checking the transfer adapter. .

Further, in the above-described embodiment, the interlocked alarm stop signal by the interlocked alarm that is the source of the alarm and the interlocked alarm stop signal by the interlocked alarm that is the destination of the alarm are not distinguished, but they may be distinguished. In the above embodiment, the alarm transfer adapter does not transfer the interlocked alarm stop signal. The alarm transfer adapter may transmit an interlocked alarm stop signal to the interlocked alarm device of its own group. Only with the interlocked alarm signal from the interlocked alarm that triggered the alarm, the interlocked alarm for the interlocked alarm in another group can be stopped. You will be able to cancel the alarm. In addition, since the interlocking alarm stop signal from the alarm device that is not the source of the alarm is not transferred, it is possible to prevent the alarm from being canceled for the entire facility when the safety is not confirmed.

In the above embodiment, interference is prevented by arranging groups to which the same channel frequency is assigned in places where the communication distance does not reach. It may be made possible to identify whether or not they are in the same group. When a group is set for an interlocking alarm device and an alarm transfer adapter, identification information unique to the device is exchanged, and whether or not the source of the interlocking signal is truly the same group depends on whether or not it matches the identification information stored when the interlocking signal is received. Identifies another group with a matching group number. As a result, even if a communication from another group with the same group number arrives, the signal can be discarded.

In the above embodiment, each alarm device communicates with each other without distinguishing between the parent unit and the child unit. Two report transfer adapters may be incorporated in the inter-group report transfer device, and the internal wiring may be used for input/output connection of the report transfer.

In the above embodiment, an interlocking alarm that detects a fire and gives an alarm is taken as an example, but the same applies to an alarm system in which gas leak alarms, CO alarms, and various crime prevention alarms are arranged. can be applied to
