Description

  The present invention relates to an alarm system that installs a plurality of alarm devices for detecting and alarming a fire in a grouped manner to perform an interlocking alarm.

  2. Description of the Related Art Conventionally, an alarm device that detects and warns of a fire in a house or the like has become widespread. Of these, residential fire alarms are referred to as residential alarms. For example, in such a house alarm, it is operated by a battery power source, and a sensor part for detecting a fire and an alarm part for alarming a fire are integrated in the house alarm, and a fire is generated based on a detection signal of the sensor part. When an alarm is detected, a fire alarm sound is output from the alarm unit, and a fire alarm and alarm notification can be performed by a single residential alarm without the need for a receiver as in the so-called automatic fire alarm system, so installation is easy. In terms of cost, it is inexpensive and has become widespread with the obligatory installation in ordinary houses.

  In addition, by performing wireless communication between multiple residential alarms, when a fire alarm sound is output from any residential alarm, other residential alarms also output a fire alarm sound. An alarm system using a type of house alarm is also in practical use and is widespread.

  For specific small-scale facilities with a floor area of less than 300 square meters, such as group homes that provide housework support for the elderly and people with intellectual disabilities, etc. Fire alarm equipment has been introduced. The automatic fire alarm system for specified small-scale facilities is composed of a sensor that integrally includes a sensor unit that detects a fire and an alarm unit that alarms the fire. When detected, all the detectors in the facility are notified and the entire facility is informed of the fire.

  Hereinafter, a sensor used in a wireless interlocking house alarm or an automatic fire alarm facility for a specific small-scale facility is referred to as an interlocking alarm.

  In such an interlocking alarm system, when a fire is detected by an interlocking alarm device, the interlocking alarm device that detected the fire is, for example, `` Check that the Wu-woo fire alarm has been activated. '' The alarm indicator LED is turned on and the alarm device that is linked to it outputs a fire alarm sound such as “Check if another fire alarm is activated”. The display LED blinks.

  However, in such a conventional wireless interlocking alarm system, when a certain interlocking alarm device receives a wireless signal from another interlocking alarm device, a plurality of wireless signals using the same communication frequency are used. May occur at the same time, causing signal collisions, and the frequency of signal collisions increases as the number of interlocked alarms installed in the alert area increases. Therefore, the number of interlocked alarms that can be installed in one alert area. The number is limited.

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

  In this group-linked alarm system, it is possible to increase the total number of linked alarm devices by linking multiple groups within the warning area. Even if a signal from an alarm device in the group and a signal from another group of alarm devices arrive at the same alarm device, signal collision does not occur, and signal transmission and reception can be performed reliably.

  The problem of this signal collision is the same in a system that does not distinguish between the main unit and sub unit of the alarm device when using a radio signal, or in a system of a parent and child system that arranges a plurality of sub units for the main unit. In the case of the parent-child method, for example, the master unit sequentially calls and processes the slave units using the individual IDs of the slave units. However, if the number of slave units increases, the overall communication is caused by an increase in the number of retries due to signal collision. take time. Therefore, in order to reduce the frequency of signal collisions with the base unit, a group is formed by limiting the number of slave units to a predetermined maximum number or less, and the base unit of each group is linked with a relay function. The alarm system uses different communication frequencies.

  For this reason, an alarm system that is larger than ordinary homes and that consists of ordinary radio-linked dwellers cannot cover the whole due to the limit on the maximum number of alarms, but in recent years it has been known as a private residence that is expected to be used. By installing an alarm system that links groups in facilities that operate simple lodging facilities under the Ryokan Business Law or specific small-scale facilities, the number of alarm devices linked to the entire facility is required while avoiding signal collision problems. Increased to a sufficient number, it is possible to provide a fire monitoring function at a low cost equivalent to the installation of a fire alarm system.

  However, in such a conventional alarm system that performs group linkage, in order to link a plurality of groups, a repeater is arranged for each group and connected by a transmission signal line. A commercial alarm can be used, but a repeater that functions as an inter-group transfer device that links the groups must be newly added. Compared to buildings, condominiums, and other facilities that are legally obligated to install, the number of products is limited and the number of production is limited.

  On the other hand, in an alarm system using a radio interlocking interlocking alarm device, a transition adapter that receives a fire interlocking signal from the interlocking alarm device and outputs a transition signal is commercially available. When the fire alarm device is connected to the migrating adapter via the migrating signal line, and the fire alarm signal is received from the interlocking alarm device by the migrating adapter, the fire alarm signal is output to the fire alarm device and automatically notified to 119 It is possible to make it.

  In addition, the migrating adapter has a migrating input terminal to enable test transmission. As a result, in addition to the wireless communication function with the interlocking alarm device, the migrating signal can be input and output. Since it is an existing product, there are few cost problems.

  For this reason, if an existing transfer adapter is used, an intergroup transfer device that links fire alarms between multiple groups of multiple alarm devices can be realized easily and at low cost. The applicant of the present application is proceeding with the study of incorporating the two information adapters into the case to make the inter-loop transfer device.

  When interlocking multiple groups of interlocking alarms using such an inter-group transfer device, when a certain interlocking alarm is activated due to a fire, for example, “Please confirm that Woo Woo Fire Alarm has been activated”. A fire alarm sound indicating the source of the interlock is output, and other interlocked alarms in the same group are also activated by sending a fire interlock signal from the activated interlocking alarm. For example, “Woooo another fire alarm is activated. Fire alarm sound indicating the link destination is output. In addition, by sending a fire interlocking signal via the inter-group transfer device, the interlocking alarms of other groups also operate, and as a result, the interlocking alarms of all groups operate and fire alarms are output. become.

  If a fire alarm is output in this way, for example, if it is a private accommodation facility, the facility manager will check the fire site and if it is confirmed that there is no fire, it will be installed in the interlocked alarm device. The fire alarm is stopped by operating the test switch.

  However, in order to stop the fire alarm, it is necessary to enter the room where the interlocking alarm is installed and perform the stop operation. In some cases, if the situation is not sufficiently explained, there may be a problem later, and there is a problem that the operation management of the alarm system cannot be performed smoothly.

  The present invention makes it possible to stop and restart a fire alarm with a simple operation by an authorized administrator or the like when a plurality of groups of alarm devices are linked by an inter-group message transfer device, thereby facilitating operation management. It is an object to provide an alarm system that can proceed to

(Basic effect)
The present invention forms a plurality of groups of a plurality of alarm devices for each warning area, and sets different channel frequencies for each group, and wirelessly transmits and receives signals between the alarm devices in the group at the same channel frequency. When each group of alarm devices detects a fire, it outputs a fire alarm indicating the interlock source, and sends a fire interlock signal to other alarm devices in the group to output a fire alarm indicating the interlock destination. In an alarm system in which a fire interlocking signal received from an alarm device of one group is transmitted to an alarm device of the other group by an inter-group message transfer device arranged between adjacent groups, the inter-group message transfer device When the alarm simultaneous stop switch is detected, the inter-group message transfer device sends an alarm simultaneous stop signal to its own group. Fire alarms are output because the fire alarms sent from each alarm device are stopped at the same time by sending them to the alarm devices of each group via the alarm device of the group and other inter-group transfer devices. If the administrator is divided into floor groups, for example, he / she goes to the inter-group relocation device installed in the staircase landing between adjacent groups to check for non-fire. By operating the alarm simultaneous stop switch as necessary, it is possible to easily stop the fire alarms output from the alarms of all groups at once, such as the room where the alarm is installed. There is no need to enter and operate, and it is possible to smoothly proceed with the operation management of an alarm system in which a plurality of groups of alarm devices are linked by an inter-group transfer device.

(Effect of simultaneous alarm stop via the message adapter)
In addition, the inter-group transfer device includes a first transfer adapter and a second transfer adapter housed in an apparatus housing having an openable / closable panel door, and the first transfer adapter is an alarm device of its own group or When a fire-linked signal is received from an inter-group transfer device arranged between adjacent groups, a fire transfer signal is output to the second transfer adapter, and the alarm device in its own group is output from the second transfer adapter. The fire alarm signal indicating the interlock destination is output by sending a fire interlock signal to the second alarm adapter, and the second migrating adapter sends a fire interlock signal from the alarm device of its own group or the inter-group alarm device arranged between adjacent groups. When received, output a fire alarm signal to the first adapter, send a fire interlock signal from the first adapter to the alarm device in its own group, and output a fire alarm indicating the interlock destination, 1st transfer adapter and (2) When the alarm adapter detects the operation of the alarm simultaneous stop switch, it sends an alarm simultaneous stop signal to the alarm devices in each group to stop the fire alarm and alarms to other inter-group alarm devices. Since the fire alarms of the alarm devices in each group are stopped by sending a simultaneous stop signal, two adapters equipped with a wireless communication function with the alarm device and an input / output function for a transfer signal are incorporated into the group. By configuring an inter-system message transfer device and installing this inter-group message transfer device in a place where a fire-linked signal from an adjacent group such as a group boundary can be received, an alarm device of a group detects a fire. In addition to fire-linked alarms within the group, fire-linked alarms are output from all alarm devices in other groups by transferring fire-linked signals from inter-group transfer devices. Hitoshi by operating the stop switch transmits an alarm broadcast stop signal the fire alarm of the alarm device of the entire group can be stopped at once.

  In addition, the two transfer adapters incorporated as the first transfer adapter and the second transfer adapter in the inter-group transfer device have an existing wireless communication function with an alarm device and an input / output function of a transfer signal. It can be realized by changing the transfer adapter by adding a function to send an alarm simultaneous stop signal by a signal from the alarm simultaneous stop switch, making it possible to manufacture the inter-group transfer device easily and at low cost. Dissemination can be promoted as specified small-scale wireless self-reporting equipment for facilities such as group homes.

(Effect by transferring alarm stop signal between alarm adapters)
In addition, when the first migrating adapter receives an alarm simultaneous stop signal from the alarm device of its own group or another inter-group migrating device arranged between adjacent groups, the first migrating adapter stops alarm simultaneously to the second migrating adapter. The second signal adapter outputs an alarm signal and transmits an alarm simultaneous stop signal from the second alarm adapter to the alarm device in its own group to stop the fire alarm. When an alarm simultaneous stop signal is received from another inter-group transfer device arranged between adjacent groups, the alarm simultaneous stop transfer signal is output to the first transfer adapter, and the first transfer adapter An alarm simultaneous stop signal is sent to the alarm devices in the group to stop the fire alarm, so the alarm simultaneous stop / transfer signal is internally sent between the two adapters incorporated in the inter-group transfer device. Send and receive In Rukoto, the transmission of the alarm broadcast stop signal to all groups of alarm devices via the inter-group transfer paper device assigned to the right to allow simultaneous stopping of the fire alarm from the alarm device of the entire group.

(Effect of stop control of linked fire alarm and linked fire alarm)
In addition, the alarm device stops both the fire alarm indicating the interlock source and the fire alarm indicating the interlock destination when the alarm simultaneous stop signal is received, so that it does not enter the room where the alarm device is installed, The fire alarms of all alarm devices can be stopped simultaneously and easily by operating the inter-group message transfer device installed in the common space such as the stair landing.

(Effect of stop control only for linked fire alarm)
In addition, when the alarm device receives the alarm simultaneous stop signal, the fire alarm indicating the link source is not stopped, but the fire alarm indicating the link destination is stopped. All fire alarms from other alarm devices are stopped, and the fire extinguisher sound that is continuously output can be used to know the location of the fire and enable early fire extinguishing and evacuation guidance to be performed promptly and appropriately.

(Effects of alarm display and acoustic alarm stop control)
In addition, the alarm device stops the acoustic alarm without stopping the alarm display of the fire alarm indicating the interlock source when the alarm simultaneous stop signal is received, and the fire alarm indicating the interlock destination is the alarm display and the acoustic alarm. Since both are stopped, it is easy to see the alarm indication that the alarm is activated when the fire alarm is stopped at the same time and you visit the site and confirm a non-fire. Can be confirmed.

(Effect of interlock prohibition by alarm stop operation of alarm device)
In addition, when an alarm is detected during a fire alarm, the alarm stops the fire alarm without sending an alarm stop interlock signal, so that an unauthorized person, such as a guest, is alerted during the fire. Even if the stop operation is performed, only the fire alarm of the operated alarm device is stopped, and the problem that the fire alarm is interlocked and stopped during the fire can be solved.

(Effects of arrangement of alarm simultaneous stop switch)
In addition, the alarm simultaneous stop switch is provided in the device casing inside the child door provided on the panel door, so that the alarm simultaneous stop switch can only be operated by an authorized administrator who knows it. This makes it possible to reliably prevent unnecessary operations by other people.

(Effect of simultaneous ringing by canceling alarm simultaneous stop)
In addition, the inter-group transfer device will sound an alarm when it detects a release operation of the alarm simultaneous stop switch while the alarm output of all alarm devices is stopped all at once by operating the alarm simultaneous stop switch. Fire alarms are temporarily output because signals are sent to the alarm devices of each group via the alarm device of the own group and the inter-group alarm device, and the fire alarms are output simultaneously from each alarm device. When a fire is confirmed by going to the site in a state of being stopped at once, the alarm simultaneous stop switch is released to simultaneously output the fire alarm output from the alarms of all groups to promote prompt evacuation action Therefore, it is possible to appropriately perform operation management by alarm stop and alarm stop cancellation based on the fire confirmation result.

(Effects of alarm ringing via a message adapter)
In addition, when the first transfer adapter and the second transfer adapter detect the release operation of the alarm simultaneous stop switch, the alarm transfer signal is sent to the alarm device in each group to release the alarm stop. In addition to restarting the output of the fire alarm, the alarm alarm signal in each group was released by sending an alarm simultaneous ringing signal to the other inter-group transfer device, so that the output of the fire alarm was restarted. An inter-group alarm device that incorporates two adapters equipped with a wireless communication function with an alarm device and an input / output function of an alarm signal is installed in a location where a fire-linked signal from an adjacent group such as a group boundary can be received. By sending the alarm simultaneous stop switch after the alarm simultaneous stop, the alarm simultaneous ringing signal is sent and the fire alarms can be output simultaneously from all the alarm devices of the alarm stopped. That.

(Effect of transferring alarm ringing signal between alarm adapters)
In addition, when the first transfer adapter receives an alarm simultaneous ring signal from the alarm device of its own group or another group inter-group transfer device arranged between adjacent groups, the first broadcast adapter transmits an alarm simultaneous ring to the second transfer adapter. Output a warning signal, send a warning ringing signal from the second warning adapter to the alarm device in its own group, restart the alarm output by releasing the alarm stop, and the second warning adapter When an alarm simultaneous alarm signal is received from the alarm device of its own group or another inter-group alarm device arranged between adjacent groups, the alarm alarm alarm signal is output to the first alarm adapter. Because one alarm adapter sends an alarm ringing signal to the alarm devices in its own group and the alarm stop is released to restart the output of the fire alarm, the two alarms installed in the inter-group alarm device are transferred. By sending and receiving the alarm simultaneous alarm signal between the adapters internally, the alarm alarm signal of all groups can be properly transmitted to the alarms of all groups via the inter-group alarm device. Enables simultaneous fire alarms.

(Effects of failure alarm and simultaneous alarm stop)
Each group alarm device outputs a failure alarm indicating the interlock source when a predetermined failure is detected, and sends a failure interlock signal to other alarm devices in the group to indicate a failure alarm indicating the interlock destination. Output the fault interlocking signal received from the alarm device of one group to the alarm device of the other group by the inter-group transmission device arranged between adjacent groups, and output the fault alarm between the groups. When the operation of the alarm simultaneous stop switch is detected, the transfer device transmits an alarm simultaneous stop signal to the alarm device of each group via its own alarm device and other inter-group transfer devices. Since the failure alarms output from each alarm device are stopped at the same time, the alarm devices of all groups can be detected based on the failure detection such as device failure of the alarm device, dead battery, or abnormal automatic communication test. When a failure alarm is output, it is possible to easily stop the failure alarm and deal with the failure by operating the inter-group transfer device, and to further facilitate the operation management of the alarm system. To do.

[Outline of alarm system]
FIG. 1 is an explanatory diagram showing an embodiment of an alarm system arranged in a hierarchical building. As shown in FIG. 1, the alarm system of the present embodiment is installed in a four-story building 11 such as a private lodging facility, for example, and the alarm area is an alarm area according to floors 1F to 4F. For example, five wireless interlocking interlocking alarm devices 10 functioning as alarm devices are installed in each of the alert areas.

  Here, five interlocking alarms 10 installed in 1F to 4F constitute groups G1, G2, G3, G4 as shown on the left side of the building 11, and groups G1, G2, G3, Each of G4 is assigned a different channel frequency f1, f2, f3, f4, and the interlocking alarm device 10 of each group G1-G5 uses the channel frequencies f1-f4 assigned to its own group. Send and receive.

  The interlocking alarm device 10 provided in each of the groups G1 to G4 outputs a fire alarm indicating the interlocking source when a fire is detected, and transmits a fire interlocking signal to other interlocking alarm devices 10 in its own group. To output a fire alarm indicating the link destination.

  Between the groups G1 to G4 corresponding to the warning areas according to the floor of the building 11, inter-group transfer devices 12-12, 12-23, and 12-34 are installed. The inter-group transfer devices 12-12, 12-23, and 12-34 can transmit and receive signals to and from both interlocking alarm devices 10 provided in adjacent floor groups. It is installed on the wall of the landing of the staircase that connects the two. In the following description, when there is no need to distinguish between the inter-group transfer devices 12-12, 12-23, and 12-34, the inter-group transfer device 12 may be referred to.

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

  For example, when an inter-group transfer device 12-12 installed between a group G1 on the first floor and a group G2 on the second floor is taken as an example, the first alarm adapter 14 has an interlocked alarm for the group G1 on the first floor. The same channel frequency f1 as that of the device 10 is set, and various signals including a fire interlocking signal are transmitted to and received from the interlocking alarm device 10 of the group G1 installed on the first floor.

  The second transfer adapter 16 has the same channel frequency f2 as that of the interlocking alarm device 10 of the group G2 on the second floor, and is connected to the interlocking alarm device 10 of the group G2 installed on the second floor. Send and receive various signals including fire-linked signals.

  The first transfer adapter 14 and the second transfer adapter 16 incorporated in the inter-group transfer device 12-12 include a transmission unit and are connected by a transmission line that functions as an internal wiring.

  The first transfer adapter 14 incorporated in the inter-group transfer device 12-12 receives the fire interlock signal having the channel frequency f1 from the interlocking alarm device 10 belonging to its own group G1. 16 outputs a fire signal. The second transfer adapter 16 that has received the fire transfer signal from the first transfer adapter 14 transmits the fire interlock signal of the channel frequency f2 to the interlock alarm 10 in its own group G2 to indicate the interlock destination. A fire alarm is output.

  In addition, the second message transfer adapter 16 incorporated in the inter-group message transfer device 12-12 receives the fire-linked signal having the channel frequency f2 from the linked alarm device 10 belonging to its own group G2, and then the first message transfer adapter 16-12. A fire alarm signal is output to the information adapter 14. The first transfer adapter 14 that has input the fire transfer signal from the second transfer adapter 16 transmits the fire link signal of the channel frequency f1 to the link type alarm device 10 in its own group G1 to indicate the link destination. A fire alarm is output.

  The functions of the first transfer adapter 14 and the second transfer adapter 16 are the same for the inter-group transfer apparatuses 12-23 and 12-34 except that the channel frequency to be used is different.

  For this reason, the channel frequency f2 of the group G2 is set in the first message transfer adapter 14 of the inter-group message transfer device 12-23, and the channel frequency f3 of the group G3 is set in the second message transfer adapter 16.

  Further, the channel frequency f3 of the group G3 is set in the first transfer adapter 14 of the inter-group transfer device 12-34, and the channel frequency f4 of the group G4 is set in the second transfer adapter 16.

  Here, the communication route of the fire interlocking signal between the groups G1 to G4 is, for example, a case where a fire is detected by the interlocking alarm device 10 of the group G1. Transfer device 12-12, Group G2 interlocking alarm device 10, Intergroup transfer device 12-23, Group G3 interlocking alarm device 10, Intergroup transfer device 12-34, and Group G4 interlocking alarm device 10 and the group G1 interlocking alarm device 10 are sent to the inter-group transfer devices 12-12, 12-23, 12-34, and the inter-group transfer devices 12-12, 12-23, There is a second route sent from 12-34 to the interlocking alarm 10 of each loop G2, G3, G4.

  As shown in FIG. 1, when the inter-group message transfer devices 12-12, 12-23, and 12-34 are arranged at a stair landing, etc., wireless transmission and reception of signals between adjacent devices is possible. Communication by two routes is performed. On the other hand, when the inter-group transfer devices 12-12, 12-23, and 12-34 are away from the communicable area, communication is performed according to the first route. Further, mixed communication of the first route and the second route is also assumed.

  The inter-group message transfer devices 12-12, 12-23, and 12-34 are provided with alarm simultaneous stop switches. When the alarm simultaneous stop switch is operated, the alarm simultaneous stop signal is sent to the interlocking alarm of the own group. Fire alarms that are transmitted to the interlocking alarm devices 10 of the respective groups via the alarm device 10 and other inter-group transfer devices and are output from the interlocking alarm devices 10 of the respective groups can be stopped simultaneously. . Details of the simultaneous stop of the fire alarm by the inter-group transfer device 12 will be clarified in later explanation.

[Functional structure 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 device 10 includes an interlocking alarm device control unit 18, a communication unit 20 including an antenna 22, a sensor unit 24, an operation indicator lamp 26, a speaker 28, and a test switch 30. Operates with battery power (not shown).

  The interlocking alarm control unit 18 is constituted by a computer circuit having a CPU, a memory, and various input / output ports.

  The communication unit 20 sets, for example, one of the four channel frequencies f1, f2, f3, and f4 in the 400 MHz band, for example, the channel frequency f1, based on an instruction from the interlocking alarm control unit 18 based on the initial setting or the like. A signal can be transmitted and received wirelessly with another interlocking alarm device 10 belonging to the same group.

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

  The sensor unit 24 is provided with a smoke detector, which detects a fire when smoke from the fire reaches a predetermined concentration. In addition to the smoke detector, a temperature detection element such as a thermistor for detecting the temperature due to a fire, and various elements for detecting other physical phenomenon changes accompanying the fire may be provided.

  The operation indicator lamp 26 displays an abnormality such as a fire by blinking, lighting, or blinking of an LED based on an instruction from the interlocking alarm control unit 18. Further, a two-color LED or two LEDs having different display colors may be provided, and the display colors may be different depending on the link source display and the link destination display. The speaker 28 outputs a voice message or warning sound by voice synthesis based on an instruction from the interlocking alarm control unit 18.

  The test switch 30 also functions as an inspection switch. An alarm stop instruction can be input only when the alarm sound of the speaker 28 and the alarm indicator 26 are displayed. When 30 is operated, a function check is performed and the result is notified.

  The control function of the interlocking alarm control unit 18 is realized by executing a program, and includes the following control functions. When the interlock type alarm device control unit 18 detects a fire based on the smoke detection signal from the smoke detecting unit provided in the sensor unit 24, an alarm sound indicating the source of the interlock from the speaker 28, for example, “Woo Woo fire alarm has been activated. “Please check” is repeatedly output, and the operation indicator lamp 26 is lit, for example, to output an alarm indicating the interlocking source.

  The interlocking alarm control unit 18 performs control to transmit a fire interlocking signal from the communication unit 20 to another interlocking alarm using the channel frequency f1 when a fire is detected.

  When the communication unit 20 receives a fire-linked signal with a channel frequency f1 from another linked alarm device, the linked alarm control unit 18 generates an alarm sound indicating the linked destination from the speaker 28, for example, “Wooly-specific fire”. Control is performed to repeatedly output an alarm sound “Please check that the alarm has been activated” and simultaneously output a fire alarm indicating the interlocking destination by blinking the operation indicator 26, for example.

  In addition, when the interlock type alarm device control unit 18 detects the alarm stop operation of the test switch 30 during the output of the fire alarm, the interlock type alarm device control unit 18 performs control to stop the alarm sound from the speaker 28 and stop the display of the operation indicator lamp 26. Do.

  Here, even if the interlock type alarm device control unit 18 detects an alarm stop operation of the test switch 30 during the output of the fire alarm, the control for transmitting the alarm stop interlock signal to the other interlock type alarm device 10 is not performed. For this reason, even if the test switch 30 is operated, the fire alarm is not stopped. This solves the problem that the fire alarm of the interlocking alarm device of another guest room that has not been stopped during a fire is stopped by a warning stop operation of a general user such as a guest.

  Furthermore, the interlocking alarm control unit 18 performs a communication test, a battery voltage drop monitoring, and a circuit failure monitoring. When a communication error, a battery voltage drop, or a circuit failure is detected, a predetermined failure alarm is output from the speaker 28. A sound is output and the operation indicator lamp 26 blinks to output a failure alarm. Further, a failure interlock signal is transmitted from the communication unit 20 to the other interlocking alarm device 10 and the inter-group transfer device 12 using the channel frequency f1. By transmitting to, control to output a failure alarm from the interlocking alarm device 10 of all groups is performed.

  By operating the alarm simultaneous stop switch provided in the inter-group transfer device 12 for the output of the failure alarm from the interlocking alarm device 10 of all the groups, all the groups are grouped as in the case of the fire alarm. Control is performed to simultaneously stop the fault alarms output from the interlocking alarm device 10.
