Description

The present invention relates to an alarm system that provides linked alarms by installing a plurality of alarm devices that detect abnormalities and issue alarms in groups.

2. Description of the Related Art Conventionally, alarm devices that detect and warn of fires in houses and the like have been in widespread use. Among these, residential fire alarms are called residential alarms. For example, such residential alarms operate on battery power, and are equipped with a sensor section that detects fire and an alarm section that alarms fire, and detect fires based on the detection signal of the sensor section. When a fire alarm is detected, a fire alarm sound is output from the alarm unit, and unlike so-called automatic fire alarm equipment, a receiver etc. is not required and fire monitoring and alarm notification can be performed with the residential alarm itself, making it easy to install. It is also inexpensive and has become widely popular as it has become compulsory to install it in general homes.

In addition, by mutually communicating wirelessly between multiple residential alarms, when a fire alarm sound is output from any residential alarm, other residential alarms will also output a fire alarm sound in conjunction with each other. Alarm systems using type of residential alarms have also been put into practical use and are becoming widespread.

In addition, for specified small-scale facilities with a floor area of less than 300 square meters that are not required to install fire alarm equipment, such as group homes that provide housework support for the elderly and intellectually disabled, automatic Fire alarm equipment has been installed. Automatic fire alarm equipment for specified small-scale facilities consists of a sensor that is integrated with a sensor unit that detects fire and an alarm unit that issues a fire alarm, and by wirelessly linking the sensors, it is possible to detect a fire using any one of the sensors. When a fire is detected, all the detectors in the facility will set off an alarm, alerting the entire facility to the fire.

Hereinafter, the sensors used in wireless interlocking residential alarms and automatic fire alarm equipment for specified 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, "Woooo fire alarm has activated. Please confirm." It outputs a fire alarm sound such as ``Woooooo, another fire alarm has activated, please check'' and lights up the alarm display LED, while the linked alarm outputs a fire alarm sound such as ``Woooooo, another fire alarm has activated, please check'' and also causes an alarm. The display LED is made to blink.

However, in such conventional wireless linked alarm systems, when one linked alarm receives a wireless signal from another linked alarm, multiple radio 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 a warning area increases. The number of units is limited.

In order to solve this problem, when forming a group consisting of multiple linked alarms, we set a maximum number of linked alarms to prevent the frequency of signal collisions from increasing. They have proposed an alarm system in which a repeater is placed between them and the communication frequencies used are different for each group (Patent Document 1).

In this group-linked alarm system, the total number of linked alarms can be increased by linking multiple groups within a warning area, and the communication frequency of the linked alarms differs depending on the group. Therefore, even if a signal from an interlocking alarm in a certain group and a signal from an interlocking alarm in another group arrive at the same time on an interlocking alarm in a certain group, no signal collision will occur, and the signal transmission and reception will not occur. can be done reliably.

This problem of signal collision is the same in systems that do not distinguish between the master unit and slave units of interlocking alarms when using wireless signals, and in parent-child systems in which multiple slave units are placed in relation to the master unit. In the parent-child system, for example, the parent device sequentially calls and processes the child devices using their individual IDs, but as the number of child devices increases, the overall number of retries increases due to signal collisions. Communication takes time. Therefore, in order to reduce the frequency of signal collisions with the base unit, the number of slave units is limited to a predetermined maximum number or less to form groups, and the base unit of each group is provided with a relay function to interlock, and furthermore, each group The alarm system uses different communication frequencies.

For this reason, the alarm system, which is larger than a typical residential building and consists of regular wireless alarms, cannot cover the entire situation due to the limit on the maximum number of alarms. By installing a group-linked alarm system in facilities that operate simple lodging facilities under the Hotel Business Act and specified small-scale facilities, it is possible to avoid the problem of signal collision and reduce the number of alarms required for the entire facility. By increasing the number to a sufficient number, it is possible to provide a fire monitoring function that is essentially equivalent to installing fire alarm equipment at a low cost.

However, in such conventional group-linked alarm systems, in order to link multiple groups, a repeater is placed for each group and connected with a mobile signal line, and a wireless linkage type alarm system is used. Commercially available interlocking alarms can be used, but a new repeater must be added to interlock between groups, and private lodging facilities, group homes, etc. are not legally required to install fire alarm equipment. Compared to mandated facilities such as buildings and condominiums, there are fewer of them, and production is limited, which increases costs and is a bottleneck to their widespread use.

On the other hand, for alarm systems using wireless interlocking alarms, there are mobile alarm adapters on the market that receive fire interlock signals from interlocking alarms and output mobile alarm signals. Connect the fire alarm device to the mobile alarm adapter with a mobile signal line, and when the mobile adapter receives a fire interlocking signal from the interlocking alarm, the fire alarm signal will be output to the fire alarm device and an automatic call will be made to 119. This makes it possible to

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 linked alarm, it is also possible to input and output transfer signals. Since it is an existing product, there are few cost issues.

Therefore, by using an existing alarm transfer adapter, it is possible to easily and at low cost realize an inter-group transfer device that links fire alarms between multiple groups of alarm devices.

On the other hand, when multiple groups of interlocking alarms are linked using such an inter-group transfer device, the interlocking alarms other than the one that detected the fire will be linked to other interlocking alarms or groups. When a fire interlocking signal is received from an interlocking alarm device, it simply outputs the fire alarm sound of the interlocking destination, such as "Woooooo, another fire alarm has activated. Please check," and the activated interlocking alarm is When it is not possible to distinguish between interlocking alarms in the same group and interlocking alarms in other groups, and it takes time and effort to confirm the location of the fire, which impedes initial fire extinguishing and evacuation. There is.

It is an object of the present invention to provide an alarm system that can output an abnormality alarm that can distinguish between groups in which alarms are activated when a plurality of groups consisting of a plurality of alarms are linked by an inter-group transfer device. purpose.

(basic effect)
The present invention configures a plurality of groups consisting of a plurality of alarm devices, sets a different channel frequency for each group, and wirelessly transmits and receives signals between the alarm devices in the group using the same channel frequency. In an alarm system, when an alarm device detects an abnormality, it outputs an abnormal alarm of the linked source, and also sends an abnormal link signal to other alarm devices in the group to output the abnormal alarm of the linked destination. When an abnormality interlocking signal is received from an alarm in one group between groups, an abnormality interlocking signal of the channel frequency of the other group is sent to cause the alarm in the other group to output the abnormality alarm of the interlocking destination. The inter-group transfer device is equipped with an inter-group transfer device, and at least one of the abnormality-linked signal transmitted from the interlocking source alarm that detected the abnormality, or the abnormality-linked signal transmitted from the inter-group transfer device on the channel frequency of the other group. Predetermined discrimination information (type information, group code, address, etc.) that makes it possible to determine whether the alarm of a 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, Based on the discrimination 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 it is determined that the alarm in the same group is the interlocking source, other alarms belonging to the same group are The alarm system outputs an abnormal alarm of the interlocking destination indicating the activation of the alarm, and if it is determined that the alarm of a different group is the interlocking source, outputs an abnormal alarm of the interlocking destination indicating the activation of an alarm belonging to a different group. The installed alarm determines whether the alarm is in the same group or another group based on predetermined identification information (type information, group code, address, etc.) and outputs a fire alarm to which it is linked, and This makes it possible to determine whether other alarms within the same group or from a different group are activated, allowing the location of the fire to be quickly identified and appropriate initial extinguishing and evacuation guidance. .

In addition, by installing the inter-group transfer device in a place where it can receive abnormality linked signals from adjacent groups, such as at group boundaries, it is possible to issue an abnormality linked alarm within the group when an alarm in a certain group detects an abnormality. In addition, by transferring the abnormality interlocking signal by the intergroup transfer device, the abnormality interlocking alarm can be outputted from all alarm devices in other groups.

(Effects of direct communication between inter-group transfer devices)
In addition, 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 system transmits an abnormality interlocking signal on the channel frequency of the other group and causes the alarms in the other group to output the abnormality alarm of the interlocking destination, for example, wireless communication between multiple intergroup transfer devices can be prevented. If this is not possible, and an alarm in one group detects an abnormality, the abnormality interlock signal from the alarm that detected the abnormality will be transmitted to the adjacent group via the inter-group transfer device. The signal is sent to the alarm device, and then sequentially sent to the alarm device in a different group from another inter-group transfer device installed between the other group and a different group. If wireless communication is possible between inter-group transfer devices, the abnormal interlock signal is sent sequentially between multiple inter-group transfer devices without going through the alarms of other groups. The alarm device can output a linked abnormality alarm based on predetermined discrimination information (type information, group code, address, etc.).

(Effect of linked abnormality alarm indicating the location of abnormality)
In addition, if the group code is not set in the received abnormal interlocking signal, the intergroup transfer device transmits an abnormal interlocking signal of the channel frequency of the other group to which the group code of one group is set, and the received abnormal interlocking signal is If a group code is already set for the abnormality interlock signal, the abnormality interlock signal of the channel frequency of the other group to which the set group code is set is transmitted, and the alarm is connected to the alarm that belongs to the other group. As a linked abnormal alarm that indicates the activation of the alarm, an abnormal alarm that indicates that the abnormality has occurred is output at a place where an alarm of another group is installed. In this case, a linked abnormality alarm indicating the floor where the abnormality has occurred is outputted from the alarm, and the location where the abnormality has occurred can be easily and reliably determined, making it possible to quickly and appropriately deal with the abnormality.

[Overview of alarm system]
FIG. 1 is an explanatory diagram showing an embodiment of an alarm system placed in a building with a hierarchical structure.
As shown in FIG. 1, the alarm system of this embodiment is installed in a four-story building 11 such as a private lodging facility, and the warning areas are for each floor from the 1st to 4th floors. For example, five wirelessly linked alarm devices 10 functioning as alarm devices are installed in each of the warning areas.

Here, the five interlocking alarms 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. , G4 are assigned different channel frequencies f1, f2, f3, f4, and the linked alarm devices 10 of each group G1 to G4 use the channel frequencies f1 to f4 assigned to their own group. to send and receive signals.

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

Furthermore, when the interlocking alarm 10 detects a fire, it transmits a fire interlocking signal in which an alarm type code indicating that it is an alarm is set as its own type information. The signal format of the fire-related signal includes, for example, a source code, a type code, and an event code. The transmission source code is a code indicating the transmission source, and uses, for example, the serial number of an alarm device. The type code indicates the type of device such as an alarm or an adapter. The event code is a code representing event details such as fire, alarm stop, failure, etc.

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

The inter-group transfer devices 12-12, 12-23, and 12-34 incorporate a first transfer adapter 14 and a second transfer adapter 16.

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

In addition, the second mobile adapter 16 is set to the same channel frequency f2 as the linked alarm device 10 of group G2 on the second floor. Transmits and receives various signals including fire-related 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 section that performs serial transmission, and are connected by a parallel transmission line serving as internal wiring.

The first transfer adapter 14 incorporated in the inter-group transfer device 12-12 transmits the fire transfer signal when receiving the fire interlock signal of channel frequency f1 from the interlock alarm 10 belonging to its own group G1. and instructs the transmission section 36 to transmit a fire alarm signal to the second alarm shifting adapter 16.

The second mobile adapter 16, which has received the fire alarm signal from the first mobile alarm adapter 14, transmits the fire interlock signal to which the adapter type code of channel frequency f2 is set to the interlocking alarm device 10 in its own group G2. and outputs a linked fire alarm indicating activation of alarms in other groups based on the adapter type code.

In addition, the second transfer adapter 16 incorporated in the inter-group transfer device 12-12 performs fire transfer when receiving a fire interlocking signal of channel frequency f2 from the interlocking alarm 10 belonging to its own group G2. It generates a signal and instructs the transmission section 36 to transmit the fire alarm signal to the first alarm shifting adapter 14.

The first mobile adapter 14, which has received the fire alarm signal from the second mobile alarm adapter 16, transmits the fire interlock signal of the channel frequency f1 to which the adapter type code is set to the interlocking alarm device 10 in its own group G1. A linked fire alarm indicating activation of alarms in other groups is output based on the adapter type information.

According to the method described above that uses type information to distinguish between the fire interlocking signal from the interlocking alarm and the fire interlocking signal from the mobile alarm adapter, the exchange of signals between the mobile adapters is based on the presence or absence of the fire mobile signal. No complicated communication is required.

Note that 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 discussed later. This will be clarified in the explanation.

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

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

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

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

As shown in FIG. 1, if the inter-group transfer devices 12-12, 12-23, and 12-34 are placed at a staircase landing, etc., and it is possible to transmit and receive signals wirelessly between adjacent devices, Communication is performed through two routes. On the other hand, when the inter-group transfer devices 12-12, 12-23, and 12-34 are far from each other's communicable area, communication follows the first route. It is also assumed that the first route and the second route may be used for mixed communication.

In the following explanation, when there is no need to distinguish between the inter-group transfer devices 12-12 to 12-34, they may be referred to as the inter-group 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 includes an interlocking alarm control section 18, a communication section 20 equipped with an antenna 22, a sensor section 24, an operation indicator 26, a speaker 28, and an alarm stop switch 30. , operates on battery power (not shown).

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

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

In Japan, the communication unit 20 has a configuration that complies with STD-30 (Low Power Security System Radio Station Radio Equipment Standard), which is known as the standard for specified low power radio stations in the 400 MHz band, for example. . Of course, for locations outside Japan, the communication section 20 will have content that complies with the standards of the assigned radio station in that region.

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

The operation indicator light 26 indicates an abnormality such as a fire by blinking, lighting, or blinking an LED based on instructions from the interlocking alarm controller 18. Alternatively, a two-color LED or two LEDs with different display colors may be provided, and the display colors may be made different between the link source display and the link target display.

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 speaker 28 is making an alarm sound and the operation indicator light 26 is making an alarm display. When the stop switch 30 is operated, a functional check is performed and the results are notified.

The control functions of the interlocking alarm controller 18 are realized by executing a program, and include 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 outputs the interlocking source alarm sound from the speaker 28, for example, “Woo-woo! The fire alarm has activated.” "Please do so" is repeatedly output, and the operation indicator light 26 is turned on, for example, to output the interlocking source fire alarm.

Furthermore, when a fire is detected, the interlocking alarm controller 18 directs a fire interlock signal in which the alarm type code is set as its own type information from the communication section 20 to other interlocking alarms using the channel frequency f1. control the transmission.

In addition, when the communication unit 20 receives a fire interlocking signal of channel frequency f1 from another interlocking alarm, and determines the alarm type code from the received fire interlocking signal, the interlocking alarm control unit 18 28 repeatedly outputs an alarm sound such as "Woo-woo, another fire alarm has activated. Please check" as the interlocking destination alarm sound, and at the same time causes the operation indicator light 26 to blink, for example, and other interlocking types in the same group Performs control to output a linked fire alarm indicating activation of the alarm.

In addition, when the interlocking alarm control unit 18 determines the adapter type code from the received fire interlock signal, this fire interlock signal is a fire interlock signal 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-woo, another group's fire alarm has activated. Please confirm" as the interlocking alarm sound, and at the same time, the operation indicator light 26 flashes, for example. control to output a linked fire alarm indicating the activation of linked alarms in other groups.

In addition, interlocking alarms can be distinguished on the display by making the operation indicator blink at different speeds when the fire interlocking signal of the alarm type code is received and when the fire interlocking signal of the adapter type code is received. It becomes possible.

In addition, when the interlocking alarm control unit 18 detects an alarm stop operation of the alarm stop switch 30 while outputting a fire alarm or a fault alarm, the interlocking alarm control unit 18 sends a group control/alarm stop interlocking signal to stop the alarm sound from the speaker 28. Controls sending to other alarms within the alarm.

Furthermore, the interlocking alarm control unit 18 performs fault monitoring such as communication tests, battery voltage drop monitoring, and circuit failure monitoring, and when a communication error, battery voltage drop, or circuit failure is detected, an alarm is sent from the speaker 28. A predetermined fault alarm sound is output, the operation indicator light 26 flashes to output a fault alarm, and a fault interlocking signal is further transmitted from the communication unit 20 to other interlocking alarm devices using channel frequency f1. control.

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

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

The first transmission adapter 14 includes an adapter control section 32, a communication section 34 to which an antenna 35 is connected, an operation indicator light 42, a speaker 44, a test switch 46, and a transmission section 36, and operates on a battery power source (not shown). The second transfer adapter 16 also has a similar configuration.

The transmission sections 36 of the first transfer adapter 14 and the second transfer adapter 16 have, for example, a serial transmission function, and are connected by a transmission line 38. The transmission line 38 is an internal wiring provided within the casing of the inter-group transfer device 12-12, and therefore there is no need to provide a disconnection monitoring function required for the wiring outside the casing.

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

The communication unit 34 is the same as the communication unit 20 provided in the interlocking type alarm device 10 in FIG. 2, and sets the channel frequency f1 assigned to the group G1 based on initial settings etc. It is possible to transmit and receive signals wirelessly to and from the alarm 10, and in Japan, for example, STD-30 (low power security system wireless Equipped with a configuration that complies with station radio equipment standards).

The operation indicator light 42 displays a fire alarm, a failure alarm, etc. by blinking, lighting, flickering, etc. of an LED based on instructions from the adapter control unit 32. The speaker 44 outputs a voice message and an alarm sound by voice synthesis based on instructions from the adapter control unit 32 . The test switch 46 performs operations such as stopping the alarm, testing communication, stopping shifting, and canceling the stopping of shifting.

The control function of the adapter control unit 32 of the first transfer adapter 14 is realized by executing a program, and includes 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 with an adapter type code set. Then, it instructs the transmission section 36 to perform control to transmit a fire alarm signal to the second alarm shifting adapter 16.

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

Further, upon receiving the fire transfer signal in which the adapter type code is set from the second transfer adapter 16 via the transmission unit 36, the adapter control unit 32 of the first transfer adapter 14 receives the fire transfer signal in which 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 transmits the fire interlocking signal with the channel frequency f1 to the interlocking alarm 10 in another group based on the adapter type code. Controls the output of a linked fire alarm indicating the activation of the fire alarm.

In addition, when the adapter control unit 32 of the first transfer adapter 14 receives a fire interlocking signal in which an alarm type code is set from an interlocking type alarm 10 in its own group G1, the adapter control unit 32 determines the alarm type code. Based on this, the speaker 44 repeatedly outputs an alarm sound saying "Woooooo, the fire alarm has been activated. Please confirm", and at the same time, the operation indicator light 42 is blinked, for example, to activate the interlocking alarms in the same group. Control is performed to output the fire transfer alarm shown.

In addition, when the adapter control unit 32 of the first alarm shifting adapter 14 receives a fire alarm signal in which the adapter type code is set from the second alarm shifting adapter 16, the adapter control unit 32 of the first alarm shifting adapter 14 outputs a message from the speaker 44 saying "Woooooo! Fire alarm of another group. is activated, please confirm.'' is repeatedly output, and at the same time, the operation indicator light 42 is blinked slowly, for example, to output a fire transfer alarm indicating the activation of an interlocking alarm in another group. .

Note that the fire alarm by the first alarm adapter 14 may not output an alarm sound, but may only be displayed by the operation indicator light 42.

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

In addition, 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 drop in battery voltage 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 an operation of blinking the operation indicator light 42 a predetermined number of times is repeated at predetermined intervals, thereby controlling to output a failure alarm.

The control function of the adapter control section 32 is similar to that of the adapter control section 32 of the second transfer adapter 16.

Further, the first transfer adapter 14 that receives the fire alarm interlocking signal from the interlocking alarm device 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 alarm signal transmits a fire interlock signal in which the adapter type code is set to the interlocking alarm device 10 in its own group G2. You may choose not to output the .

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

As a result, if the first alarm adapter 14 and the second alarm adapter 16 issue an alarm at the same time, the voices will be mixed and it will be difficult to hear the alarm. avoid becoming difficult.

Further, the second transfer adapter 16 receives a fire interlocking signal set with an adapter type code of channel frequency f2 assigned to group G2, which is transmitted from the adjacent inter-group transfer device 12-23 shown in FIG. may be received. In this case, the adapter control section 32 of the second transfer adapter 16 controls the transmission section 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 interlock signal in which the adapter type code is set, and instructs the communication unit 34 to A fire interlocking signal in which the adapter type code of channel frequency f1 assigned to group G1 is set is sent to the interlocking alarm 10 in its own group G1, and the interlocking alarm in other groups is activated based on the adapter type code. Performs control to output a linked fire alarm indicating activation.

In this way, the fire interlock signal is transferred via the inter-group transfer devices 12-12, 12-23, and 12-34, since there is no communication via the interlocking alarms 10 of each group during that time. It becomes possible to link fire alarms of group G4, which is farthest from group G1, in which a fire has been detected, for example, in a shorter communication time.

[Control operation of transfer adapter]
FIG. 4 is a flowchart showing the control operation of the transfer adapter device incorporated in the inter-group transfer device, and shows the control operation of the first transfer adapter 14 incorporated in the inter-group transfer device 12-12 of FIG.

A fire transfer signal with an adapter type code set is transmitted to the alarm adapter 16, and then, in step S4, the alarm type code set in the fire transfer signal is determined and the interlocking type alarm in group G1 is transmitted. An interlocked fire alarm indicating the operation of is output by the alarm sound from the speaker 44 and the operation of the operation indicator light 42.

Further, when the adapter control section 32 determines in step S5 that the transmission section 36 has received a fire transfer signal in which the adapter type code is set from the second transfer adapter 16, the process proceeds to step S6, where the adapter type code is set. The communication unit 34 is instructed to transmit the fire interlock signal of the channel frequency f1 assigned to the own group G1, and then the adapter type set as the fire transfer signal in step S7 is generated. The code is discriminated, and a fire transfer alarm indicating the operation of the interlocking alarms in group G2 is output by the alarm sound from the speaker 44 and the operation of the operation indicator light 42.

Further, when the adapter control unit 32 determines in step S8 that an alarm stop 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 S9, and the adapter control unit 32 proceeds to step S9 to indicate whether a fire transfer alarm is in progress or a failure alarm is in progress. If it is determined that the fire alarm is inside, the process proceeds to step S10, and the fire transfer alarm is stopped.

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

Please check", and the operation indicator light 26, for example, flashes, and other linked alarms in the same group are output. Outputs a linked fire alarm indicating the operation of the device.

On the other hand, if the alarm type code cannot be determined in step S28, the process proceeds to step S30, and if the adapter type code is determined, the process proceeds to step S31, where the speaker 28 outputs, for example, "Woooo, the fire alarm of another group has activated. Please check. "Please" is repeatedly outputted, and the operation indicator light 26 is blinked, for example, to output an interlocked fire alarm indicating the operation of another group's interlocked alarm.

Subsequently, when the interlocking alarm control unit 18 determines in step S32 that the alarm stop interlocking signal has been received, or determines that the alarm stop switch 30 has been operated in step S33, the interlocking alarm control unit 18 proceeds to step S34 and outputs the signal in step S29.

Please check", and the operation indicator light 26 is blinked, for example. , outputs a linked fire alarm indicating the activation of other linked alarms in the same group.

On the other hand, if the source address is not the address assigned to the interlocking alarm in step S68, the process proceeds to step S70, and if it is determined that the source address is the adapter-assigned address, the process proceeds to step S71, where the speaker 28 emits, for example, "Woooo other... "The fire alarm of the group has activated. Please confirm" is repeatedly output, and the operation indicator light 26 is blinked, for example, to output a linked fire alarm indicating the operation of the linked alarm of another group.

Subsequently, when the interlocking alarm control unit 18 determines in step S72 that the alarm stop interlocking signal has been received, or when it determines that the alarm stop operation has been performed in step S73, the process proceeds to step S74, and the interlocking destination fire output in step 69 is performed.
