Description

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

Conventionally, alarm devices that detect and give an alarm in a house or the like have become widespread. Of these, residential fire alarms are called residential alarms. For example, such a resident fire alarm operates on a battery power source, and has a sensor unit for detecting a fire and an alarm unit for warning a fire in the resident fire alarm, and fires based on the detection signal of the sensor unit. When it is detected, a fire alarm sound is output from the alarm unit, and unlike the so-called automatic fire alarm system, it does not require a receiver, etc., and the fire alarm can be monitored and alarmed by itself, so installation is easy. It is also inexpensive and has become widespread as it becomes mandatory to install it in ordinary houses.

In addition, when a fire alarm sound is output by any of the smoke detectors by mutually 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 a fire alarm system, 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 specified small-scale facilities consists of a sensor that has a sensor unit that detects a fire and an alarm unit that warns of a fire. When a fire is detected, all the sensors in the facility issue a fire alarm 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, please check that the fire alarm has been activated." While outputting a fire alarm sound such as, and turning on the alarm display LED, on the other hand, the interlocking destination alarm output a fire alarm sound such as "Woo, another fire alarm has been activated. Please check" and an alarm. 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 limited.

In order to solve this problem, when forming a group consisting of multiple interlocking alarms, the maximum number of interlocking alarms restricted so that the frequency of signal collisions does not increase is set, and the multiple 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 in another group arrive at the interlocking alarm of a certain group at the same time, no signal collision occurs 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 for 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 number of slave units is limited to a predetermined maximum number or less to form a group, and the master unit of each group is provided with a relay function to work together. 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 have 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, a repeater is 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 compulsory 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 widespread use.

On the other hand, in an alarm system using a wireless interlocking type interlocking alarm, a transfer adapter that receives a fire interlocking signal from the interlocking alarm and outputs an interlocking transfer signal is commercially available, for example. , When the fire alarm device is connected to the transfer adapter by the transfer signal line and the fire interlocking signal is received by the transfer adapter from the interlocking alarm, the fire interlocking transfer signal is output to the fire alarm device and dialed 119. It is possible to make an automatic report.

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 interlocked transfer signals. Since it is an existing product, there are few cost issues.

Therefore, if the 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 consisting of a plurality of alarms. Therefore, the existing transfer is possible. The applicant of the present application is proceeding with the study of incorporating two alarm adapters into the housing to form an inter-loop alarm transfer device.

When multiple groups of interlocking alarms are interlocked using such an intergroup transfer device, the two transfer adapters incorporated in the intergroup transfer device use their respective transfer output terminals as the other party. By connecting a signal line to the transfer input terminal, the fire interlocking transfer signal is input and output to each other.

However, in addition to the fire interlocking signal, the fire alarm sends and receives various signals such as an alarm stop interlocking signal, a device failure interlocking signal, a battery exhaustion interlocking signal, and a communication test signal. In order to link in the same way, it is necessary to transfer other linked signals other than fire with the intergroup transfer device, but there is a problem that the existing transfer adapter is vulnerable to sending and receiving linked transfer signals and cannot handle it. ..

In addition to the fire interlocking signal, when various signals such as alarm stop interlocking signal, equipment failure interlocking signal, battery exhaustion interlocking signal, communication test signal, etc. are transferred between groups, each of them is transferred between groups. The problem remains as to how to establish the optimum interlocking form for the method of alarming between groups for signals.

(Setting the same channel frequency for a group of remote alert areas)
The same channel frequency is set for a group placed in a monitoring area that exceeds the communication range of the alarms of a predetermined group .

(Basic effect)
The present invention is an alarm system in which a plurality of groups consisting of a plurality of alarm devices are configured, and a different channel frequency is set for each group, and signals are wirelessly transmitted and received between the alarm devices in the group at the same channel frequency. , The alarms provided in each group perform the control operation of the event source when a predetermined event is detected, transmit the event interlocking signal to other alarms, and the other alarms in their own group specify. When the event interlocking signal when the event of is detected or the signal based on the event interlocking signal is received, the control operation of the event destination when the event source is in the group is performed , and one group is placed between the adjacent groups. The first transfer adapter for transmitting and receiving signals wirelessly with the alarm device of the above and the second transfer adapter for transmitting and receiving signals wirelessly with the alarm device of the other group are provided, and the first transfer adapter and the second transfer adapter are provided. An inter-group transfer device that transmits and receives a predetermined signal is arranged, and the first transfer adapter and the second transfer adapter of the inter-group transfer device are based on an event-linked signal or an event -linked signal from an alarm device of its own group. When a signal is received, an event-linked transfer signal is transmitted to the other transfer adapter, and the transfer event- linked signal is transmitted from the other transfer adapter to the alarm device in the group to which the other transfer adapter belongs . Since the control operation of the event destination is performed when the event source is different from the case where the event source is in the group, the first transfer adapter and the second transfer adapter provided in the intergroup transfer device have a predetermined signal. When a signal based on various event-linked signals or event -linked signals transmitted from an alarm is received, it is converted into a corresponding event-linked transfer signal and transferred from the first transfer adapter to the second transfer. By transmitting the event interlocking signal sent to the adapter and from the second transfer adapter to the first transfer adapter and transmitted by the alarm of one group to the alarm of another group, the alarm of each group The control operation can be surely linked. In addition, when performing the control operation of the event destination, the control operation of the event destination differs depending on whether the event source is its own group, so it is possible to perform the control operation in consideration of the group (location) of the event source. Become.

(Effect of group linkage of failure alarm)
In addition, the alarms provided in each group output a failure alarm indicating the interlocking source when a failure including equipment failure or battery exhaustion is detected, and also transmit a failure interlocking signal to other alarms to detect their own. When another alarm in the group receives a failure interlocking signal or a signal based on the failure interlocking signal when a failure including a device failure or a dead battery is detected, a failure indicating that the interlocking source is in the group and the interlocking destination. An alarm is output , and the first transfer adapter and the second transfer adapter of the intergroup transfer device receive a failure interlocking signal or a signal based on the failure interlocking signal from the alarm device of its own group, and the interlocking source is the group. A group to which a failure alarm indicating the interlocking destination is output and a failure transfer signal is transmitted to the other transfer adapter, and the transfer failure interlocking signal is sent from the other transfer adapter to the other transfer adapter. Since the signal is transmitted to another intergroup transfer device that can send and receive signals at the channel frequency of, and a fault alarm indicating the link destination when the link source is outside the group is output, a failure alarm is output from the alarm device of the own group. The intergroup transfer device that has received the interlocking signal or the signal based on the failure interlocking signal outputs a failure alarm indicating the interlocking destination when the interlocking source is in the group, and outputs the failure interlocking signal to another intergroup transfer device. By transmitting and outputting a failure alarm indicating the interlocking destination when the interlocking source is outside the group, and outputting the failure alarm only from multiple intergroup transfer devices, the room where the alarm is installed, etc. Only the administrator can confirm the failure without causing anxiety to general users. In addition, it is possible to output a failure alarm after considering whether or not the interlocking source is its own group.

(Effect of group interlocking of alarm stop)
In addition, the interlocking source alarm stops the fault alarm indicating the interlocking source when an alarm stop operation is detected during the fault alarm, and also sends a fault alarm stop interlocking signal to another alarm, and the interlocking source alarm. The alarm device of the interlocking destination of the group stops the fault alarm indicating the interlocking destination when the interlocking source is in the group when receiving the fault alarm stop interlocking signal or the signal based on the fault alarm stop interlocking signal, and between the groups. The first transfer adapter and the second transfer adapter of the transfer device are within the group when the failure alarm stop interlocking signal or the signal based on the failure alarm stop interlocking signal is received from the alarm device of its own group . The fault alarm indicating the interlocking destination of the case is stopped, and the fault alarm stop transfer signal is transmitted to the other transfer adapter, and the signal is transmitted and received from the other transfer adapter at the channel frequency of the group to which the other transfer adapter belongs . Since the transfer failure alarm stop interlocking signal is transmitted to other possible intergroup transfer devices to stop the failure alarm indicating the interlocking destination when the interlocking source is outside the group, including equipment failure or battery exhaustion. When the administrator confirms the failure and performs the stop operation of the failure alarm with the alarm device of the interlocking source during the failure alarm that detected the failure, the same group is transmitted by transmitting the alarm stop interlocking signal or the signal based on the failure alarm stop interlocking signal. The failure alarm of the interlocking destination alarm is stopped, and the failure alarm by all the intergroup transfer devices can be stopped by the alarm stop interlocking signal transmitted via the intergroup transfer device. Operation management for fault alarms can be easily performed.

(Effect of communication test by transfer adapter)
Further, the first transfer adapter or the second transfer adapter provided in the inter-group transfer device transmits a communication test signal to the alarm device in the own group, and all the members in the own group within a predetermined time. When the communication test response signal is received from the alarm device, the test result is judged to be normal, and when the communication test response signal is not received from all the alarm devices in the own group within the specified time, the test result abnormality is judged. Because the alarm is given from the alarm in the own group, the radio wave is normally transmitted to all the alarms in the own group using the same channel frequency every communication test cycle such as once every 72 hours. It is possible to easily check whether or not the alarm is moving, and it is possible to ensure the reliability of the alarm system by wirelessly interlocking the alarm.

(Effect of communication test of the other transfer adapter by request of one transfer adapter)
Further, either the first transfer adapter or the second transfer adapter of the intergroup transfer device is further transferred to the other transfer adapter when transmitting a communication test signal to the alarm device in its own group. When the communication test request signal is transmitted and the other transfer adapter receives the communication test request signal from one transfer adapter, the other transfer adapter transmits the communication test signal to the alarm device in its own group within a predetermined time. When the communication test response signal is received from all the alarms in the own group, the test result is judged to be normal, and when the communication test response signal is not received from all the alarms in the own group within the specified time. Because the test result abnormality is judged and an alarm is given, the communication test of the alarm device in another group can be performed by the other transfer adapter in conjunction with the communication test of one transfer adapter. It is not necessary to separately test the communication of the alarm with the 1st transfer adapter and the 2nd transfer adapter.

(Effect of communication test when another intergroup transfer device belongs to one of the transfer adapter groups)
Further, when the first transfer adapter or the second transfer adapter provided in the inter-group transfer device belongs to one of the other inter-group transfer devices in its own group , the first transfer adapter or the second transfer adapter belongs to its own group. The communication test signal was transmitted to the alarm device in the room and the other inter-group signal transfer device, and the communication test response signal was received from all the alarm devices in the own group and the other inter-group signal transfer device within a predetermined time. In this case, the test result is judged to be normal, and if the communication test response signal is not received from all the alarms in the own group and other intergroup transfer devices within the specified time, the test result abnormality is judged and the self is judged. Since the alarm is issued from the alarm device in the group and the other inter-group signal transfer device, the communication test with the other inter-group signal transfer device belonging to the same group is accompanied by the communication test operation by any of the transfer adapters. Specifically, it is possible to perform a communication test with a transfer adapter using the same channel frequency built into another intergroup transfer device, which allows intergroup transfer by any transfer adapter. Whether or not radio waves are reaching between the devices can be confirmed, and the reliability of the wireless communication connection between the intergroup transfer devices can be ensured.

(Effect of internal wiring)
Further, since the transmission line for transmitting and receiving a predetermined signal between the first transfer adapter and the second transfer adapter is provided as the internal wiring inside the housing of the intergroup transfer device, the external wiring to the device housing is provided. Since there is a risk of disconnection due to the external environment, it is necessary to provide a disconnection monitoring function, but since it is an internal wiring, it is not necessary to provide an electric wire monitoring function, which makes manufacturing easier and reduces costs. Make it possible.

(Effect of setting the same channel frequency for groups in remote alert areas)
In addition, the same channel frequency is set for groups placed in multiple monitoring areas that exceed the communication range of the alarms of the specified group, so if there is no risk of interference, the same channel frequency will be used multiple times. By being able to repeatedly set to groups, it is possible to reduce the number of channel frequencies to be set even if the number of interlocking groups increases.

Explanatory diagram showing another embodiment of the warning system arranged in a hierarchical building

[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 floor-based warning area 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 each 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. 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. Then, fire monitoring control is performed to output a fire alarm indicating the interlocking destination.

The signal format of the fire interlocking signal transmitted by the interlocking alarm device 10 is composed of, for example, a source code, a group code, an event code, and the number of relays. The source code is a code indicating a source, and for example, a serial number of an alarm is used. The group code indicates the group to which the self belongs. The event code is a code representing an event content such as a fire, an alarm stop, or a failure. The number of relays is a code that decreases by 1 each time the interlocking alarm 10 relays the fire interlocking signal. For example, if 3 times is initially set as the number of relays, the number of relays becomes zero after 3 relays. , Do not perform the next relay. This prevents the fire interlocking signal from being relayed indefinitely.

Further, the interlocking alarm 10 performs failure monitoring control and automatic communication test control in addition to fire monitoring control.

An inter-group transfer device 12-12, 12-23, 12-34 is installed between the groups G1 to G4 corresponding to the caution area for each floor of the building 11. Since the inter-group transfer device 12-12, 12-23, 12-34 enables transmission and reception of signals 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 stairs.

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

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 has an interlocking alarm of 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 and received to and from the interlocking alarm device 10 of the group G1 installed on the first floor. Therefore, the first transfer adapter 14 of the intergroup transfer device 12-12 is included in the group G1 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 second floor, and is between the second transfer adapter 16 and the interlocking alarm 10 of the group G2 installed on the second floor. Sends and receives various signals including fire interlocking signals. Therefore, the second transfer adapter 16 of the intergroup transfer device 12-12 is included in the group G2 on the second floor.

The first transfer adapter 14 and the second transfer adapter 16 incorporated in the intergroup transfer device 12-12 include a transmission unit for serial transmission or parallel transmission, and the first transfer adapter 14 and the second transfer adapter Appropriate signals can be transmitted and received between 16.

When the first transfer adapter 14 incorporated in the intergroup 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 as intergroup fire interlocking control. In addition, a fire interlocking transfer signal is output to the second transfer adapter 16. The second transfer adapter 16 to which the fire interlocking transfer signal from the first transfer adapter 14 is input transmits the fire interlocking signal of the channel frequency f2 to the interlocking alarm 10 in its own group G2, and the interlocking destination. A fire alarm is output.

The second transfer adapter 16 incorporated in the intergroup transfer device 12-12 also receives a fire interlocking signal having a channel frequency f2 from the interlocking alarm 10 belonging to its own group G2 as intergroup fire interlocking control. In this case, the fire interlocking transfer signal is output to the first transfer adapter 14. The first transfer adapter 14 to which the fire interlocking transfer signal from the second transfer adapter 16 is input transmits the fire interlocking signal of the channel frequency f1 to the interlocking alarm 10 in its own group G1 to interlock the destination. A fire alarm is output.

Such inter-group fire interlocking control of the first transfer adapter 14 and the second transfer adapter 16 is the same for the inter-group transfer devices 12-23, 12-34, except that the channel frequencies used are different. Become.

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 channel frequency f3 of the group G3 is set in the first transfer adapter 14 of the intergroup 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 and 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 are sent to the intergroup transfer devices 12-12, 12-23, 12-34, and the intergroup transfer devices 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 intergroup transfer devices 12-12, 12-23, 12-34 are arranged at the landing of the stairs, etc., and the 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.

Further, in the first transfer adapter 14 and the second transfer adapter 16 provided in the inter-group transfer device 12, in addition to the inter-group fire interlocking control, the interlocking alarm 10 has a failure such as a device failure or a dead battery. Inter-group failure interlocking control when detected, and inter- group automatic communication test control for confirming whether or not radio waves have reached the interlocking alarm 10 in its own group are performed.

[Interlocking alarm]
(Functional configuration of interlocking alarm)
FIG. 2 is a block diagram showing a functional configuration of an interlocking alarm. 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 a test switch 30. It operates on a battery power supply (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. , It is possible to wirelessly transmit and receive signals 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 specific low power radio stations 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 due to the fire reaches a predetermined concentration.

The first transfer adapter 14 is set to the channel frequency f1 of the group G1, 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 includes an adapter control unit 32, a communication unit 34 to which the antenna 36 is connected, a transmission unit 38, an operation indicator lamp 42, a speaker 44, and a test switch 46, and operates with a battery power supply (not shown).

The inter-group transfer device 12-12 is provided with a panel door that can be opened and closed on the front surface of a box-shaped device housing that opens to the front. By opening the panel door, the first transfer adapter 14 and the second transfer adapter 14 and the second are provided. The transfer adapter 16 has a structure that can be visually recognized.

The transmission unit 38 of the first transfer adapter 14 and the second transfer adapter 16 are connected by a transmission line 40, and the transmission line 40 is provided as internal wiring. When the transmission line 40 is externally wired to the device housing, it is necessary to provide a disconnection monitoring function because there is a risk of disconnection due to the external environment. However, in the present embodiment, the transmission line 40 is internally wired. As a result, it is not necessary to provide a wire monitoring function, which makes it easier to manufacture and reduce costs.

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, and the communication unit 34 of the first transfer adapter 14 is the channel frequency f1 assigned to the group G1 based on the initial settings and the like. Is set so that signals can be transmitted and received wirelessly to and from the interlocking alarm 10 belonging to the same group G1. It has a configuration compliant with the STD-30 (low power security system radio station radio equipment standard).

The transmission unit 38 has, for example, a serial transmission function or a parallel transmission function, and transmits and receives signals including various interlocking transfer signals and communication test related signals.

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, transfer stop, and 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 performs predetermined control including inter-group fire interlocking control, inter-group failure interlocking control, and inter-group automatic communication test control. The inter-group fire interlocking control includes inter-group alarm stop interlocking control.

(Fire interlocking control between groups)
When the adapter control unit 32 of the first transfer adapter 14 receives the fire interlocking signal of the channel frequency f1 from the interlocking alarm 10 of its own group G1, it instructs the transmission unit 38 to instruct the transmission unit 38 and the second transfer adapter 16 Controls to transmit a fire-linked transfer signal via the transmission line 40.

The adapter control unit 32 of the second transfer adapter 16 that received the fire interlocking transfer signal from the first transfer adapter 14 via the transmission unit 38 instructs the communication unit 34 to set the channel in the group G2. It controls to transmit a fire interlocking signal having a frequency f2 to an interlocking alarm 10 in its own group G2 and output a fire alarm indicating an interlocking destination outside the group.

[Group channel frequency setting]
FIG. 12 is an explanatory diagram showing another embodiment of the warning system arranged in the building having a hierarchical structure. As shown in FIG. 12, in the alarm system of the present embodiment, a plurality of interlocking alarm devices 10 are arranged in groups on the 1st floor to the 6th floor of a 6-story building 11 and each group is arranged. Intergroup transfer devices 12-12, 12-23, 12-34, 12-45, 12-56 are arranged at the landing of the stairs that serve as the boundary.

The allocation of the channel frequencies f1 to f4 of the groups G1 to G4 of the 1F to 4F of the present embodiment is the same as that of the embodiment of FIG. 1, but the group G1 having the same channel frequency f1 as the 1F is assigned to the 5F. Further, a group G2 having the same channel frequency f2 as the 2F is assigned to the 6F.

Here, the interlocking alarm 10 installed in each group has a limit in its communicable distance. For example, the radio wave from the interlocking alarm 10 installed on the 1st floor is the interlocking type installed on the 5th floor. It does not reach the alarm 10.

Even if the interlocking alarm 10 with the same channel frequency f1 is installed in the 1st floor and the 5th floor, which are warning areas separated from the communicable area of the interlocking alarm 10, signals are sent to each other. Since it cannot send and receive, there is no problem of interference. This point is the same between the 2nd floor and the 6th floor.

Therefore, in the present embodiment, the same channel frequency f1 is set with the 1F and 5F separated beyond the communicable area of the interlocking alarm 10 as the group G1, and similarly, the same channel with the 2F and 6F as the group G2. The frequency f2 is set, and even if the number of interlocking groups increases, the number of channel frequencies to be set can be reduced without causing interference.

[Modified example of the present invention]
In the above embodiment, the alarm devices communicate with each other regardless of whether the master unit or the slave unit is used. However, a master unit and a slave unit are provided in each channel group, and input / output is connected to the master unit of the adjacent group. It is also possible to incorporate two transfer adapters into the intergroup transfer device so that the transfer can be input / output and connected by internal wiring.

Further, the above embodiment is an example of an interlocking alarm device that detects a fire and gives an alarm, but the same applies to an alarm system in which a gas leak alarm device, a CO alarm device, and various security alarm devices are arranged. Can be applied to.

Further, the flowchart in the above embodiment explains a schematic example of the processing, and the order of the processing and the like is not limited to this. In addition, a delay time can be provided for each process or between processes as needed, or another determination can be inserted.

Further, the present invention is not limited to the above-described embodiment, includes appropriate modifications that do not impair its purpose and advantages, and is not further limited by the numerical values shown in the above-described embodiment.
