Description

The present invention relates to an alarm system in which a plurality of alarm devices that detect an abnormality and give an alarm are installed by grouping to give an interlocking alarm.

Conventionally, alarms that detect and warn fires in houses and the like have become widespread. Of these, residential fire alarms are called residential alarms. For example, in such a resident fire alarm, it operates on a battery power source, and a sensor unit for detecting a fire and an alarm unit for warning a fire are integrally provided in the resident fire alarm, and a fire is generated based on the detection signal of the sensor unit. When a fire alarm is detected, a fire alarm sound is output from the alarm unit, and unlike the so-called automatic fire alarm system, fire monitoring and alarm notification can be performed by the Smoke Detector alone without the need for a receiver, etc., so installation is easy. It is also inexpensive and has become widespread due to the mandatory installation in ordinary houses.

In addition, when a fire alarm sound is output by any of the smoke detectors by performing wireless communication between multiple smoke detectors, the other smoke detectors also work together to output a fire alarm sound. An alarm system using a type of smoke detector has also been put into practical use and has become widespread.

In addition, for specific small-scale facilities with a floor area of less than 300 square meters that are not obliged to install fire alarm equipment, such as group homes that support household chores for the elderly and people with intellectual disabilities, automatic for specific small-scale facilities. Fire alarm system has been introduced. The automatic fire alarm system for specific small-scale facilities is composed of a sensor that detects a fire and an alarm that warns of a fire, and the sensors work together wirelessly to cause a fire. When it is detected, all the sensors in the facility issue a report to notify the entire facility of the fire.

Hereinafter, the detector used for the wireless interlocking residential police device and the automatic fire alarm system for a specific small-scale facility will be referred to as an interlocking alarm device.

In such an interlocking alarm system, when a fire is detected by the interlocking alarm, the interlocking alarm that detected the fire is, for example, "Woo Woo fire alarm activated. Please check." While outputting a fire alarm sound such as, and turning on the alarm display LED, the interlocking destination alarm output a fire alarm sound such as "Woo, another fire alarm has been activated. Please check." The display LED is blinking.

However, in such a conventional wireless interlocking alarm system, when one interlocking alarm receives a radio signal from another interlocking alarm, a plurality of wireless signals using the same communication frequency are used. May arrive at the same time and cause a signal collision, and the frequency of signal collisions increases as the number of interlocking alarms installed in the warning area increases, so the interlocking alarms that can be installed in one warning area The number is restricted.

In order to solve this problem, when forming a group consisting of a plurality of interlocking alarms, the maximum number of interlocking alarms restricted so that the frequency of signal collision does not increase is set, and the plurality of groups formed in this way. We have proposed an alarm system in which repeaters are arranged and interlocked between them, and the communication frequencies used for each group are different (Patent Document 1).

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

This problem of signal collision is the same in a system that does not distinguish between the master unit and the slave unit of the interlocking alarm when using a wireless signal, and in a parent-child system in which multiple slave units are arranged with respect to the master unit. Yes, 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, but when the number of slave units increases, the total number of retries due to signal collision increases. Communication takes time. Therefore, in order to reduce the frequency of signal collisions with the master unit, the slave units are limited to a predetermined maximum number or less to form a group, and the master units of each group are interlocked with each other by providing a relay function. It is an alarm system with different communication frequencies used for.

For this reason, the warning system, which is larger than ordinary houses and consists of ordinary wirelessly interlocking residential alarms, cannot cover the entire area due to the limitation of the maximum number of alarms, but in recent years, it is known as a private lodging that is expected to be used. By installing an alarm system that links groups to facilities that operate simple lodgings under the Ryokan Business Law and specific small-scale facilities, it is necessary to increase the number of alarms linked to the entire facility while avoiding the problem of signal collision. The number has been increased to a sufficient number, and it is possible to provide a fire monitoring function equivalent to the installation of fire alarm equipment at low cost.

However, in such a conventional alarm system that performs group interlocking, in order to interlock between a plurality of groups, repeaters are arranged for each group and connected by a transfer signal line, which is a wireless interlocking type. Commercially available interlocking alarms can be used, but it is necessary to add a new repeater for interlocking between groups, and it is legal to install fire alarm equipment in private lodging facilities and group homes. Compared to mandatory facilities such as buildings and condominiums, the number is small and the number of production is limited, so the cost is high and it is a bottleneck for popularization.

On the other hand, in an alarm system using a wireless interlocking interlocking alarm, a transfer adapter that receives a fire interlocking signal from the interlocking alarm and outputs a transfer signal is commercially available, for example. When a fire alarm device is connected to the transfer adapter via a transfer signal line and a fire interlocking signal is received by the transfer adapter from the interlocking alarm, the fire transfer signal is output to the fire alarm device and automatically notified to No. 119. It is possible to make it happen.

In addition, the transfer adapter is equipped with a transfer input terminal to enable test transmission, and as a result, in addition to the wireless communication function with the interlocking alarm, it is possible to input and output transfer signals. Since it is an existing product, there are few cost issues.

Therefore, if an existing transfer adapter is used, it is possible to easily and at low cost realize an intergroup transfer device that links a fire alarm between a plurality of groups composed of a plurality of alarms.

On the other hand, when multiple groups of interlocking alarms are interlocked using such an intergroup transfer device, the interlocking alarms other than the interlocking alarm that detected the fire are other interlocking alarms or groups. When a fire interlocking signal is received from the interlocking device, it only outputs the interlocking destination fire alarm sound, for example, "Woo, another fire alarm has been activated. Please check." When it is not possible to distinguish between other interlocking alarms in the same group or interlocking alarms of another group, it takes time and effort to confirm the location of the fire, and the initial fire extinguishing or evacuation is supported. There is.

The present invention provides an alarm system that enables the output of an abnormality alarm that can distinguish the group in which the alarm is activated when a plurality of groups consisting of a plurality of alarms are linked by an intergroup transfer device. The purpose.

(Basic effect)
The present invention constitutes a plurality of groups consisting of a plurality of alarms, sets different channel frequencies for each group, and wirelessly transmits and receives signals between the alarms in the group at the same channel frequency, and alarms for each group. When an abnormality is detected, the device outputs an abnormality alarm of the interlocking source, and at the same time, sends an abnormality interlocking signal to other alarms in the group to output an abnormality alarm of the interlocking destination. When an abnormal interlocking signal is received from an alarm in one group between groups, an abnormal interlocking signal of the channel frequency of the other group is transmitted so that the alarm in the other group outputs an abnormal interlocking alarm. The same as at least one of the anomaly interlocking signal transmitted from the interlocking source alarm that has detected an abnormality or the anomaly interlocking signal transmitted from the intergroup alarm device at the channel frequency of the other group. Predetermined identification information (type information, group code, address, etc.) that enables the determination of whether the alarm of the group is the interlocking source or the alarm of another group is the interlocking source is set, and the alarm that receives the abnormal interlocking signal is Based on the determination information of the predetermined information, it is determined whether the alarm in the same group is the interlocking source or the alarm in another group is the interlocking source, and if the alarm in the same group is determined to be the interlocking source, another alarm belonging to the same group is determined. An abnormality alarm of the interlocking destination indicating the operation of the device is output, and when an alarm device of another group determines that it is the interlocking source, an abnormality alarm of the interlocking destination indicating the operation of the alarm device belonging to another group is output. The provided alarm outputs a fire alarm of the interlocking destination that determines whether the alarm of the same group or another group is the interlocking source based on the predetermined discrimination information (type information, group code, address, etc.), and the alarm is concerned. By this, it is possible to know whether another alarm in the same group is operating or another group's alarm is operating, and it is possible to quickly identify the location of the fire and appropriately perform initial fire extinguishing and evacuation guidance. ..

In addition, by installing an inter-group signal transfer device in a place where an abnormality interlocking signal from an adjacent group such as a group boundary can be received, an abnormality interlocking alarm within the group when an alarm of a certain group detects an abnormality In addition, the abnormality interlocking alarm can be output from all the alarms of other groups by transferring the abnormality interlocking signal by the intergroup transfer device.

(Effect of direct communication between intergroup transfer devices)
Further, when the inter-group transfer device receives an abnormal interlocking signal of the channel frequency of one group from another inter-group transfer device, predetermined discrimination information (type information, group code, address, etc.) is set. Since the abnormality interlocking signal of the channel frequency of the other group is transmitted and the alarm device in the other group outputs the abnormality alarm of the interlocking destination, for example, wireless communication is performed between a plurality of intergroup transfer devices. If it is not possible, if one group of alarms detects an anomaly, the anomaly interlocking signal from the alarm that detected the anomaly will be sent to the other adjacent group via the intergroup transfer device. Multiple intergroup signals sent to the alarm, followed by another intergroup transfer device located between the other group and a different group, sequentially sent to a different group of alarms, but arranged between the groups. When wireless communication is possible between group-to-group information transfer devices, anomalous interlocking signals are sequentially sent between multiple group-to-group information transfer devices without going through alarms of other groups, so that all groups It is possible to output an interlocking destination abnormality alarm based on predetermined discrimination information (type information, group code, address, etc.) with the alarm device of.

(Effect of interlocking destination abnormality alarm indicating the location of abnormality)
Further, the intergroup transfer device transmits and receives an abnormal interlocking signal of the channel frequency of the other group in which the group code of one group is set when the group code is not set in the received abnormal interlocking signal. When the group code is already set for the abnormal interlocking signal, the abnormal interlocking signal of the channel frequency of the other group for which the set group code is set is transmitted, and the alarm is an alarm belonging to another group. As an abnormality alarm of the interlocking destination indicating the operation of, an abnormality alarm indicating that the place where the alarm of another group is installed is the place where the abnormality occurred is output. Outputs an abnormality alarm of the interlocking destination indicating the abnormality occurrence floor from the alarm device, and makes it possible to easily and surely determine the abnormality occurrence location and quickly and appropriately deal with the abnormality.

[Overview of alarm system]
FIG. 1 is an explanatory diagram showing an embodiment of an alarm system arranged in a building having a hierarchical structure.
As shown in FIG. 1, the warning system of the present embodiment is installed in a four-story building 11 such as a private lodging facility, and the warning area is a warning area for each floor on the 1st to 4th floors. For example, five wirelessly interlocking interlocking alarms 10 that function as alarms are installed in each of the warning areas.

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

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

Further, when a fire is detected, the interlocking alarm device 10 transmits a fire interlocking signal in which an alarm device type code indicating that the alarm device is used is set as its own type information. The signal format of the fire interlocking signal is composed of, for example, a source code, a type code, and an event code. The source code is a code indicating a source, and for example, a serial number of an alarm is used. The type code indicates the type of device such as an alarm or adapter. The event code is a code representing the content of an event such as a fire, an alarm stop, or a failure.

Inter-group transfer devices 12-12, 12-23, 12-34 are installed between groups G1 to G4 corresponding to the warning areas for each floor of the building 11. Since the inter-group signal transfer device 12-12, 12-23, 12-34 enables signals to be transmitted and received to and from both interlocking alarms 10 provided in groups on adjacent floors, for example, each floor. It will be installed on the wall of the landing of the stairs connecting the two.

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

For example, taking the intergroup transfer device 12-12 installed between the group G1 on the first floor and the group G2 on the second floor as an example, the first transfer adapter 14 is an interlocking alarm device of the group G1 on the 1st floor. The same channel frequency f1 as 10 is set, and various signals including a fire interlocking signal are transmitted and received to and from the interlocking alarm 10 of the group G1 installed on the first floor.

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

The first transfer adapter 14 and the second transfer adapter 16 incorporated in the inter-group transfer device 12-12 include, for example, a transmission unit that performs serial transmission, and are connected by a parallel transmission line that serves as internal wiring.

When the first transfer adapter 14 incorporated in the inter-group transfer device 12-12 receives a fire interlocking signal having a channel frequency f1 from an interlocking alarm 10 belonging to its own group G1, it transmits a fire transfer signal. It is generated and instructed to the transmission unit 36 to transmit a fire alarm signal to the second transfer adapter 16.

Upon receiving the fire transfer signal from the first transfer adapter 14, the second transfer adapter 16 sends a fire interlocking signal in which the adapter type code of the channel frequency f2 is set to the interlocking alarm 10 in its own group G2. Is sent to, and an interlocking destination fire alarm indicating the operation of the alarm of another group is output based on the adapter type code.

Further, the second transfer adapter 16 incorporated in the inter-group transfer device 12-12 receives a fire interlocking signal having a channel frequency f2 from the interlocking alarm 10 belonging to its own group G2, and causes a fire transfer. A signal is generated, and the transmission unit 36 is instructed to transmit the fire alarm signal to the first transfer adapter 14.

Upon receiving the fire transfer signal from the second transfer adapter 16, the first transfer adapter 14 transmits the fire interlocking signal of the channel frequency f1 in which the adapter type code is set to the interlocking alarm 10 in its own group G1. It sends and outputs an interlocking destination fire alarm that indicates the alarm operation of another group based on the adapter type information.

According to the method of distinguishing the fire interlocking signal from the interlocking alarm and the fire interlocking signal from the transfer adapter using the type information as described above, the signal exchange between the transfer adapters is the presence or absence of the fire transfer signal. It only needs to be, and does not require complicated communication.

The first transfer adapter 14 and the second transfer adapter 16 may output a fire transfer alarm when receiving a fire interlocking signal or a fire transfer signal, but this point will be described later. It will be clarified in the explanation of.

The functions of the first transfer adapter 14 and the second transfer adapter 16 are the same for the intergroup 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 in the first transfer adapter 14 of the intergroup transfer device 12-23, and the channel frequency f3 of the group G3 is set in the second transfer adapter 16.

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

Here, the communication route of the fire interlocking signal between the groups G1 to G4 is, for example, when a fire is detected by the interlocking alarm 10 of the group G1, the interlocking alarm 10 of the group G1 and the intergroup. Transfer device 12-12, group G2 interlocking alarm 10, intergroup transfer device 12-23, group G3 interlocking alarm 10, intergroup transfer device 12-34 and group G4 interlocking alarm The first route to be 10, and the interlocking alarm 10 of the group G1 sent the inter-group alarms 12-12, 12-23, 12-34, and the inter-group alarms 12-12, 12-23, There is a second route sent from 12-34 to the interlocking alarms 10 of each group G2, G3, G4.

As shown in FIG. 1, when the inter-group transfer devices 12-12, 12-23, 12-34 are arranged at the landing of the stairs or the like and adjacent devices can transmit and receive wireless signals, the first Communication is performed by two routes. On the other hand, when the intergroup transfer devices 12-12, 12-23, and 12-34 are far from the communicable area, the communication follows the first route. Further, it is assumed that the first route and the second route are mixed communication.

When it is not necessary to distinguish between the intergroup transfer devices 12-12 to 12-34 in the following description, it may be referred to as an intergroup transfer device 12.

[Functional 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 battery power (not shown).

The interlocking alarm control unit 18 is composed of a computer circuit including 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 the instruction from the interlocking alarm control unit 18 based on the initial settings and the like. , Signals can be wirelessly transmitted and received to and from other interlocking alarms 10 belonging to the same group.

In the case of Japan, the communication unit 20 has a configuration compliant with STD-30 (low power security system radio station radio equipment standard), which is known as a standard for a specific low power radio station in the 400 MHz band, for example. .. Of course, the communication unit 20 will have the contents conforming to the standard of the assigned radio station in the area for the place other than Japan.

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

The operation indicator lamp 26 displays an abnormality such as a fire by blinking, lighting, blinking, or the like of the LED based on the instruction of 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 between the display of the interlocking source and the display of the interlocking destination.

The speaker 28 outputs a voice message or an alarm sound by voice synthesis based on the instruction of the interlocking alarm control unit 18.

The alarm stop switch 30 also functions as an inspection switch, and can input an alarm stop instruction only when the alarm sound of the speaker 28 and the alarm display of the operation indicator lamp 26 are being performed, and an alarm is given in a normal state. When the stop switch 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 has the following control functions.

When the interlocking alarm control unit 18 detects a fire from the smoke detection unit provided in the sensor unit 24 based on the smoke detection signal, the interlocking source alarm sound, for example, "Woo Woo fire alarm has been activated" is confirmed from the speaker 28. "Please do" is repeatedly output, and the operation indicator lamp 26 is turned on, for example, to output the interlocking source fire alarm.

Further, when a fire is detected, the interlocking alarm control unit 18 directs a fire interlocking signal in which an alarm type code is set as its own type information from the communication unit 20 to another interlocking alarm using the channel frequency f1. Controls the transmission.

Further, when the interlocking alarm control unit 18 receives a fire interlocking signal having a channel frequency f1 from another interlocking alarm in the communication unit 20, and determines the alarm type code from the received fire interlocking signal, the speaker From 28, for example, an alarm sound such as "Woo, another fire alarm has been activated, please check" is repeatedly output as an interlocking destination alarm sound, and at the same time, the operation indicator light 26 is blinked, for example, and other interlocking types in the same group. Controls to output an interlocking fire alarm that indicates the operation of the alarm.

Further, when the interlocking alarm control unit 18 determines the adapter type code from the received fire interlocking signal, the fire interlocking signal is sent from another group via the intergroup transfer device 12. Since it is a signal, the speaker 28 repeatedly outputs an alarm sound such as "Woo, another group of fire alarms have been activated. Please check" as an interlocking destination alarm sound, and at the same time, the operation indicator light 26 blinks, for example. It controls to output an interlocking destination fire alarm indicating the operation of the interlocking alarms of other groups.

In addition, the interlocking alarm can be distinguished by displaying by making the blinking speed of the operation indicator different when receiving the fire interlocking signal of the alarm type code and when receiving the fire interlocking signal of the adapter type code. It will be possible.

Further, the interlocking alarm control unit 18 groups a control / alarm stop interlocking signal for stopping the alarm sound from the speaker 28 when the alarm stop operation of the alarm stop switch 30 is detected during the output of the fire alarm or the failure alarm. Controls transmission to other alarms in.

Further, the interlocking alarm control unit 18 performs failure monitoring such as communication test, battery voltage drop monitoring, circuit failure monitoring, etc., and when a communication error, battery voltage drop, or circuit failure is detected, the speaker 28 is used. A predetermined failure alarm sound is output, the operation indicator lamp 26 is blinked to output a failure alarm, and a failure interlocking signal is transmitted from the communication unit 20 to another interlocking alarm device using the channel frequency f1.

FIG. 3 is a block diagram showing the functional configuration of the inter-group transfer device, and the inter-group transfer device 12-12 installed between the group G1 on the 1st floor and the group G2 on the 2nd floor in FIG. 1 is taken as an example. The same applies to the other intergroup transfer devices 12-23, 12-34.

As shown in FIG. 3, the intergroup transfer device 12-12 is provided with a first transfer adapter 14 and a second transfer adapter 16 in one device housing. The first transfer adapter 14 is different in that the channel frequency f1 of the group G1 is set, and the second transfer adapter 16 is set to the channel frequency f2 of the group G2. , Basically the same.

The first transfer adapter 14 is composed of an adapter control unit 32, a communication unit 34 to which the antenna 35 is connected, an operation indicator 42, a speaker 44, a test switch 46, and a transmission unit 36, and operates with a battery power supply (not shown). The second transfer adapter 16 has the same configuration.

The transmission unit 36 of the first transfer adapter 14 and the second transfer adapter 16 has, for example, a serial transmission function, and is connected by a transmission line 38. The transmission line 38 is an internal wiring provided in the housing of the intergroup transfer device 12-12, and therefore it is not necessary to provide a disconnection monitoring function required for wiring outside the housing.

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

The communication unit 34 is the same as the communication unit 20 provided in the interlocking alarm device 10 of FIG. 2, sets the channel frequency f1 assigned to the group G1 based on the initial settings, etc., and is an interlocking type belonging to the same group G1. Signals can be transmitted and received wirelessly to and from the alarm 10, and in the case of Japan, for example, STD-30 (low power security system radio) known as a standard for specific low power radio stations in the 400 MHz band. It has a configuration that conforms to the station radio equipment standard).

The operation indicator 42 displays a fire transfer alarm, a failure alarm, or the like by blinking, lighting, blinking, or the like of the LED based on the instruction of the adapter control unit 32. The speaker 44 outputs a voice message or an alarm sound by voice synthesis based on the instruction of 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 transfer adapter 14 is realized by executing a program, and has the following control functions.

When the adapter control unit 32 of the first transfer adapter 14 receives a fire interlocking signal of the first channel frequency f1 from the interlocking alarm 10 of its own group G1, it generates a fire transfer signal in which the adapter type code is set. Then, the transmission unit 36 is instructed to control the transmission of the fire alarm signal to the second transfer adapter 16.

The adapter control unit 32 of the second transfer adapter 16 that has received the fire transfer signal from the first transfer adapter 14 via the transmission unit 36 generates a fire interlocking signal in which the adapter type code is set, and is a communication unit. Instructs 34 to transmit a fire interlocking signal of channel frequency f2 set in group G2 to the interlocking alarm 10 in its own group G2, and controls to output an interlocking pre-disaster alarm corresponding to the adapter type code. ..

Further, when the adapter control unit 32 of the first transfer adapter 14 receives the fire transfer signal for which the adapter type code is set from the second transfer adapter 16 via the transmission unit 36, the adapter type code is set. Generates a fire interlocking signal, instructs the communication unit 34 to transmit the fire interlocking signal of channel frequency f1 to the interlocking alarm 10 in its own group G1, and the interlocking alarm in another group based on the adapter type code. Controls to output an interlocking fire alarm that indicates the operation of.

Further, when the adapter control unit 32 of the first transfer adapter 14 receives a fire interlocking signal in which the alarm type code is set from the interlocking alarm device 10 in its own group G1, the adapter control unit 32 determines the alarm device type code. Based on the above, the speaker 44 repeatedly outputs an alarm sound that says "Woo Woo fire alarm has been activated. Please check." At the same time, the operation indicator 42 blinks, for example, to activate the interlocking alarm in the same group. Controls the output of the indicated fire alarm.

Further, when the adapter control unit 32 of the first transfer adapter 14 receives the fire transfer signal in which the adapter type code is set from the second transfer adapter 16, the speaker 44 “Woo Woo another group of fire alarms. Is activated. Please check. ”Is repeatedly output, and at the same time, the operation indicator 42 is controlled to blink slowly, for example, to output a fire transfer alarm indicating the operation of another group's interlocking alarm. ..

The fire transfer alarm by the first transfer adapter 14 may not output an alarm sound, but may only display the fire transfer alarm by the operation indicator lamp 42.

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

Further, the adapter control unit 32 of the first transfer adapter 14 receives a failure interlocking signal transmitted by detecting a communication failure, a failure, or a decrease in the battery voltage with the interlocking alarm 10 in its own group G1. In this case, a voice message indicating the content of the failure is output from the speaker 44, and a failure alarm is output by repeating the operation of blinking the operation indicator 42 a predetermined number of times at predetermined time intervals.

The control function of the adapter control unit 32 is the same as that of the adapter control unit 32 of the second transfer adapter 16.

Further, the first transfer adapter 14 that receives the fire alarm interlocking signal from the interlocking alarm 10 in its own group G1 outputs the fire transfer alarm and transmits the fire transfer signal to the second transfer adapter 16. However, the second transfer adapter 16 that has received the fire transfer signal transmits a fire interlocking signal in which the adapter type code is set to the interlocking alarm 10 in its own group G2, but the fire transfer alarm You may not output.

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

As a result, if the first transfer adapter 14 and the second transfer adapter 16 give an alarm at the same time, the voices are mixed and it becomes difficult to hear. However, by not performing the alarm operation of the transfer adapter on the side where the fire transfer signal is received, it is possible to hear. Avoid becoming difficult.

Further, the second transfer adapter 16 transmits a fire interlocking signal in which the adapter type code of the channel frequency f2 assigned to the group G2 transmitted from the adjacent intergroup transfer device 12-23 shown in FIG. 1 is set. May be received. In this case, the adapter control unit 32 of the second transfer adapter 16 controls the transmission unit 36 to transmit a fire transfer signal in which the adapter type code is set to the first transfer adapter 14.

When the adapter control unit 32 of the first transfer adapter 14 receives the fire transfer signal from the second transfer adapter 16, it generates a fire interlocking signal in which the adapter type code is set and instructs the communication unit 34. A fire interlocking signal in which the adapter type code of the channel frequency f1 assigned to the group G1 is set is transmitted to the interlocking alarm 10 in its own group G1, and the interlocking alarm in another group is transmitted based on the adapter type code. Controls to output an interlocking fire alarm that indicates operation.

In this way, the transfer of the fire interlocking signal via the intergroup transfer device 12-12, 12-23, 12-34 does not include communication via the interlocking alarm 10 of each group during that time. For example, it is possible to link the fire alarm of the group G4 farthest from the group G1 when the fire is detected in a shorter communication time.
