Description

The present invention relates to an inter-group alarm transfer device for an alarm system used for grouping a plurality of alarm devices that detect and give an alarm for a fire and perform 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 will 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 alarms restricted so that the frequency of signal collision does not increase is set, and between the plurality of groups formed in this way. We have proposed an alarm system in which repeaters are arranged and interlocked, and the communication frequencies used for each group are different (Patent Document 1).

In this group-linked warning system, the total number of alarms linked can be increased by linking multiple groups within the warning area, and different groups have different alarm communication frequencies, so a certain group. Even if a signal from an alarm device in the group concerned and a signal from an alarm device in another group arrive at the alarm device at the same time, signal collision does not occur and the signal can be reliably transmitted and received.

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 alarm when using a wireless signal, and in a parent-child system in which a plurality of slave units are arranged with respect to the master unit. In the case of the parent-child method, for example, the master unit sequentially calls and processes the slave units using the individual IDs of the slave units, but when the number of slave units increases, the number of retries due to signal collision increases, resulting in overall communication. time consuming. 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 wireless 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 a repeater that functions as an intergroup transfer device that links groups must be newly added, and private lodging facilities and group homes are equipped with fire alarms. Compared to facilities such as buildings and condominiums that are legally required to be installed, 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.

(Basic effect)
The present invention constitutes a plurality of groups consisting of a plurality of alarms for each warning area, sets different channel frequencies for each group, and wirelessly transmits and receives signals between the alarms in the group at the same channel frequency. , Each group's alarm outputs a fire alarm indicating the interlocking source when a fire is detected, and also sends a fire interlocking signal to other alarms in the group to output a fire alarm indicating the interlocking destination. The system is configured and placed in a position where it can communicate with both adjacent groups, and the fire interlocking signal received from the alarm of one group is transmitted to the alarm of the other group to give an alarm. In the alarm device, since the first report adapter and the second report adapter that mutually transfer information between groups are provided in the device housing of the inter-group information transfer device, the alarm device is provided in the device housing. By incorporating two existing transfer adapters equipped with a wireless communication function and a transfer signal input / output function as the first transfer adapter and the second transfer adapter as they are with only slight changes, between groups. It is possible to easily and inexpensively manufacture an inter-group alarm system that links fire alarms with, and a warning system that links fire alarms between multiple groups consisting of multiple alarms is provided at facilities such as private lodgings and group homes. It will be possible to promote the spread as a specific small-scale wireless fire alarm system.

In addition, since the first transfer adapter and the second transfer adapter are incorporated in the inter-group transfer device, it is not necessary to install them separately and transfer the transfer by external wiring, and the installation location in the target facility Since the selection can be done in one place, the installation location can be easily and easily determined, and since there is no need to externally wire each other, the installation work can be easily and easily performed.

(Effect of transfer connection between 1st transfer adapter and 2nd transfer adapter)
Further, the first transfer adapter and the second transfer adapter are provided with a transfer output terminal and a transfer input terminal, and the transfer output terminal of the first transfer adapter is used as the transfer input terminal of the second adapter in the device housing. Since the transfer output terminal of the second transfer adapter is connected to the transfer input terminal of the first adapter by the internal wiring in the device housing, the first transfer adapter and the second transfer are connected. As an information adapter, two existing transfer adapters equipped with a wireless communication function with an alarm and a transfer input / output function will be incorporated into an intergroup transfer device, and each input / output terminal will be connected by internal wiring. With simple work, it is possible to make an inter-group transfer device, and the device cost can be significantly reduced.

Further, since the connection between the transfer input / output terminals of the first transfer adapter and the second transfer adapter is a connection by internal wiring, there is a risk of disconnection due to the external environment in the connection by external wiring between the conventional repeaters. It is not necessary to provide a disconnection monitoring function, which is required because of its potential, and the manufacturing is easy and the cost can be reduced accordingly.

(Effect of connecting the battery power supply of the first transfer adapter and the battery power supply of the second transfer adapter)
Further, the first transfer adapter and the second transfer adapter are provided with a battery power source, and the battery power source of the first transfer adapter and the battery power source of the second transfer adapter are connected by an internal power supply line in the device housing. As a result, the lifespan of the battery power supplies provided separately for the first and second transfer adapters is different, and one of the battery power supplies drops below the threshold voltage that issues a predetermined battery voltage drop warning prompting battery replacement. However, it is backed up by the other battery power source at a higher voltage, and it is possible to substantially extend the battery life, and either the first transfer adapter or the second transfer adapter can be used. It is possible to prevent the function as an inter-group information transfer device from being lost due to a decrease in battery voltage.

(Effect of transfer between group transfer devices)
Further, the first transfer adapter outputs a fire transfer signal to the second transfer adapter when it receives a fire interlocking signal of the first channel frequency from another intergroup transfer device, and outputs the fire transfer signal from the second transfer adapter. The fire interlocking signal of the second channel frequency is transmitted to the alarm device in its own group to output the interlocking destination fire alarm, and the second adapter is another intergroup alarm system different from the other intergroup alarm system. When the fire interlocking signal of the second channel frequency is received from, the fire interlocking signal of the first channel frequency is output to the first transfer adapter, and the fire interlocking signal of the first channel frequency is output from the first transfer adapter to the alarm in its own group. Because the interlocking destination fire alarm is output by sending to, for example, when the alarm device of the first group to which the first transfer adapter belongs detects a fire, the fire interlocking from the alarm device that detected the fire The signal is sent via an intergroup alarm to an adjacent second group of alarms, followed by another intergroup transfer between the second group and the next third group. It is sent sequentially from the alarm device to the third alarm, but if wireless communication is possible between multiple intergroup alarms arranged between groups, a fire will occur between the multiple intergroup alarms. By sending the interlocking signals in sequence, it is possible to output a fire alarm with the alarms of all groups.

(Effect of delay control 1 for inter-group transfer)
In addition, the first transfer adapter outputs a fire transfer signal to the second transfer adapter when it receives a fire interlocking signal of the first channel frequency from its own group alarm or another intergroup transfer device. Then, after a predetermined delay time has elapsed from the second transfer adapter, a fire interlocking signal of the second channel frequency is transmitted to an alarm device in its own group to output an interlocking destination fire alarm, and the second transfer adapter , When a fire interlocking signal of the second channel frequency is received from an alarm device of its own group or another inter-group signal transfer device, the fire transfer signal is output to the first transfer adapter and from the first transfer adapter. After a predetermined delay time has elapsed, a fire interlocking signal of the first channel frequency is transmitted to an alarm device in its own group to output an interlocking destination fire alarm. Therefore, for example, the first transfer adapter is its first. At the timing when the fire interlocking signal is received from the group alarm, communication is being performed between the alarms in the first group, and the second transfer adapter receives the fire transfer signal from the first transfer adapter. If a fire interlocking signal is immediately transmitted to the second group, the first group and the second group will communicate at the same time. In this case, the adjacent first and second transfer adapters have adjacent channel frequencies. The signal is transmitted and received in, and the signals between the alarms of each other become an interfering wave, which hinders communication. However, in the present invention, communication from the transfer adapter on the side receiving the transfer is performed. By delaying, communication interference can be avoided.

(Effect of delay control 2 for inter-group transfer)
The first transfer adapter fires to the second transfer adapter after a predetermined delay time elapses when a fire interlocking signal of the first channel frequency is received from its own group alarm or another intergroup transfer device. A transfer signal is output, and a fire interlocking signal of the second channel frequency is transmitted from the second transfer adapter to an alarm device in its own group to output an interlocking destination fire alarm.
The second transfer adapter fires to the first transfer adapter after a predetermined delay time elapses when a fire interlocking signal of the second channel frequency is received from its own group alarm or another intergroup transfer device. In the case of delayed communication 1, since the transfer signal is output and the fire interlocking signal of the first channel frequency is transmitted from the first transfer adapter to the alarm device in its own group to output the interlocking destination fire alarm. Similarly, the first and second transfer adapters that are close to each other transmit and receive signals at adjacent channel frequencies, and the signals between the alarms of each other become interference waves, which hinders communication. In the present invention, communication interference can be avoided by delaying communication from the transfer adapter on the side receiving the transfer.

(Effect of the representative indicator light of the inter-group transfer device)
The first and second transfer adapters incorporated in the device housing display operations such as fire transfer alarms and fault alarms by the operation indicators provided for each, but they open and close with respect to the device housing. By providing a representative operation light on the freely provided panel door, the operation display of the first transfer adapter or the second transfer adapter is displayed as a representative, and the first transfer adapter and the second transfer adapter and the second transfer adapter can be displayed without opening the panel door. The operating status of the transfer adapter can be checked from the outside.

(Effect of fire transfer alarm of transfer adapter)
In addition, the first and second transfer adapters provided in the inter-group transfer device output a predetermined fire alarm sound when a fire interlocking signal is received from an alarm device in its own group. Since the operation indicator and the representative operation light are activated to notify the fire alarm, it is possible to confirm the occurrence of a fire from the output of the fire alarm even with the intergroup alarm installed in the warning area.

(Effect of interlocking stop control of fire alarm)
In addition, when the first transfer adapter and the second transfer adapter receive the alarm stop interlocking signal from the alarm device in their own group, the fire alarm sound, the operation indicator light, and the representative operation light give the fire alarm. Since the notification is stopped, the interlocking control to stop the fire alarm is performed within the same group, and by transferring the alarm to another group and not stopping the alarm, unnecessary confusion can be avoided.

In addition, the first and second transfer adapters provided in the inter-group transfer device stop the fire transfer alarm when the alarm stop interlocking signal is received from the alarm device in its own group. Therefore, the fire transfer alarm can be stopped appropriately in conjunction with the alarm stop operation by the alarm in the same group.

(Effect of interlocking control of fault alarm)
In addition, the first transfer adapter and the second transfer adapter receive a failure interlocking signal transmitted when a communication failure, failure, or a decrease in battery voltage is detected by an alarm in its own group. Since the specified failure alarm sound is output and the own operation indicator light and representative operation light are activated to notify the failure alarm, the failure alarm remains in the same group and the failure alarm is not output from other groups. This makes it possible to avoid unnecessary confusion.

(Effect of notification of transfer source)
In addition, since the inter-group transfer device is provided with a panel door, one or both of the transfer adapters, and an indicator or an audio output device indicating which of the transfer adapters is the transfer source, a fire alarm is output. In such a case, the group that is the source of the report can be easily identified by tracing the notification of the source of the report of the plurality of inter-group transfer devices.

(Effect of transfer source indicator light)
In addition, the inter-group transfer device is operated on the panel door when the first transfer adapter is the transfer source and the first transfer source indicator light is activated, and when the second transfer adapter is the transfer source. A second transfer source indicator light is provided, or the first transfer adapter is the transfer source and the second transfer adapter is the transfer source on the panel door of the intergroup transfer device. Since a transfer source indicator light is provided to identify and display, when a fire alarm is output, the group that became the issue source can be identified by looking at the transfer source indicator lights of multiple intergroup transfer devices. It's easy to find out.

[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. Different channel frequencies f1, f2, f3, and f4 are assigned to each of G4, and the interlocking alarms 10 of each group G1 to G5 use the channel frequencies f1 to f4 assigned to their own group. Sends and receives 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.

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. When it is not necessary to distinguish between the intergroup transfer devices 12-12, 12-23, and 12-34 in the following description, it may be referred to as an intergroup transfer device 12.

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 are provided with a transfer input terminal and a transfer output terminal, and provide a transfer output terminal of the first transfer adapter 14. The transfer input terminal of the second transfer adapter 16 is connected by internal wiring, and the transfer output terminal of the second transfer adapter 16 is connected to the transfer input terminal of the first transfer adapter 14 by internal wiring. There is.

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

Further, the second transfer adapter 16 incorporated in the inter-group transfer device 12-12 transfers the first when it receives a fire interlocking signal of channel frequency f2 from the interlocking alarm 10 belonging to its own group G2. A fire transfer signal is output to the information adapter 14. The first transfer adapter 14 that has input the fire transfer signal from the second transfer adapter 16 transmits the fire interlocking signal of the channel frequency f1 to the interlocking alarm 10 in its own group G1 to indicate the interlocking destination. Output a fire alarm.

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 alarm 10 of the group G1 and the intergroup transfer. Device 12-12, group G2 alarm 10, intergroup transfer device 12-23, group G3 interlocking alarm 10, intergroup transfer device 12-34, and group G4 interlocking alarm 10. One route and the group G1 alarm 10 sent the inter-group alarms 12-12, 12-23, 12-34, and the inter-group alarms 12-12, 12-23, 12-34 each loop. There is a second route sent to the interlocking alarm 10 of 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.

[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 wireless 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. However, 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.

[Functional configuration of inter-group transfer device]
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 includes an adapter control unit 32, a communication unit 34 to which the antenna 36 is connected, an operation indicator 42, a speaker 44, and a test switch 46. It is composed of a transfer output unit 38 connected to the transfer output terminal 83a, a transfer input unit 40 connected to the transfer input terminal 40a, and a battery power supply 48. The second transfer adapter 16 has the same configuration.

The transfer output terminal 38a of the first transfer adapter 14 is connected to the transfer input terminal 40a of the second transfer adapter 16 by the internal wiring 52, and the transfer input terminal 40a of the first transfer adapter 14 is connected to the transfer input terminal 40a of the first transfer adapter 14. The internal wiring 54 from the transfer output terminal 38a of the second transfer adapter 16 is connected.

The transfer output unit 38 outputs a non-voltage contact signal by connecting the transfer input unit 40 on the second transfer adapter 16 side with the internal wiring 52. That is, the transfer input unit 40 of the second transfer adapter 16 applies a power supply voltage to one of the internal wirings 52 via a pull-up resistor, and the transfer output unit 38 of the first transfer adapter 14 has a power supply voltage. A non-voltage a contact that is turned on by the operation of the relay is connected between the internal wirings 52.

When the first transfer adapter 14 outputs a transfer signal, the non-voltage a contact of the transfer output unit 38 is turned on by the operation of the relay to pass a current through the internal wiring 52, and the transfer of the second transfer adapter 16 is performed. The voltage between the internal wirings seen from the input unit 40 drops to substantially zero volt, and the voltage drop of the internal wiring 52 is detected to detect the input of the fire signal. The transfer output unit 38 of the second transfer adapter 16 and the transfer input unit 40 of the first transfer adapter 4 also input and output non-contact voltage signals in the same manner.

The transfer 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.

A representative operation light 50 is provided corresponding to the operation indicator 42 of the first transfer adapter 14 and the operation indicator 42 of the second transfer adapter 16. As will be clarified later, the representative operation light 50 is provided on a panel door that is openable and closable with respect to the device housing, and is an indicator light branched from a signal line for each operation indicator light 42. The wiring 58 is connected to the representative operation light 50, and the representative operation light 50 is displayed and driven by taking the logical sum (or) of the two display signals.

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 30 performs operations such as alarm stop, communication test, report transfer stop, and report transfer stop release.

The battery power supply 48 uses a primary battery such as a lithium battery, and the battery life of more than 10 years is guaranteed by reducing the power consumption of the adapter circuit.

Each adapter circuit of the information adapter 14 and the second information transfer adapter 14 is supplied with power by two battery power sources 48 connected in parallel.

Therefore, the life of the battery power supply 48 individually provided for the first transfer adapter 14 and the second transfer adapter 16 is different, and one of the battery power supplies prompts the battery to be replaced. ) Is output, even if the voltage drops below the threshold voltage, backup is performed by the other battery power supply at a higher voltage, and the battery life can be substantially extended. It is possible to prevent one of the second transfer adapters 16 from becoming inoperable due to a voltage drop of the battery power supply 48 and losing the function as the intergroup transfer device 12.

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, the adapter control unit 32 operates the transfer output unit 42 to perform the second transfer. Control is performed to output a fire alarm signal to the signal transfer adapter 16.

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

Further, when the adapter control unit 32 of the first transfer adapter 14 detects the input of the fire transfer signal from the second transfer adapter 16, it instructs the communication unit 34 to transmit the fire interlocking signal of the 1-channel frequency f1 by itself. Control is performed to output a fire alarm indicating the interlocking destination by transmitting to the interlocking alarm 10 in the group G1 of the above.

Further, when the adapter control unit 32 of the first transfer adapter 14 receives a fire interlocking signal from the interlocking alarm 10 in its own group G1, it confirms that the “Woo fire alarm has been activated” from the speaker 44. The alarm sound "Please" is repeatedly output, and at the same time, the operation indicator 42 and the representative operation light 50 are controlled to blink, for example, to output a fire 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 and the representative operation lamp 50.

Further, the adapter control unit 32 of the first transfer adapter 14 stops the fire transfer alarm when it receives an alarm stop interlocking signal from the interlocking alarm 10 in its own group G1 during the fire transfer alarm. Control to make it.

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 and the representative operation light 50 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 second transfer adapter 16 may receive a fire interlocking signal having a channel frequency f2 set in the group G2 transmitted from the adjacent intergroup transfer devices 12-23 shown in FIG. In this case, the adapter control unit 32 of the second transfer adapter 16 operates the transfer output unit 42 to control the output of the fire transfer signal to the first transfer adapter 14.

When the adapter control unit 32 of the first transfer adapter 14 detects the input of the transfer signal from the second transfer adapter 16, it instructs the communication unit 34 to interlock with the fire of the channel frequency f1 set in the group G1. Control is performed by transmitting a signal to the interlocking alarm device 10 in its own group G1 to output an interlocking destination fire alarm.

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.

As shown in FIG. 7, a circuit board is incorporated in the adapter housing of the first transfer adapter 14 and the second transfer adapter 16 from which the cover has been removed, and an operation display using an LED is used on the circuit board. A light 42, a speaker 44 behind an acoustic hole, a transfer terminal block 72, and an extension terminal block 74 are arranged.

Of these, the extension terminal block 74 is a member not found in the existing transfer adapter 100 of FIG. 6, and is newly added for the arrangement of the representative operation light 50 and the interconnection of the battery power supply. Other than that, the structure is the same as that of the existing transfer adapter 100 of FIG.

FIG. 8 is an explanatory diagram showing the terminal connection by the internal wiring of the first transfer adapter and the second transfer adapter incorporated in the intergroup transfer device.

As shown in FIG. 8, the transfer terminal block 72 provided on the first transfer adapter 14 and the second transfer adapter 16 includes a pair of transfer output terminals 38a and a pair of transfer input terminals 40a. It has terminals, and a wiring attachment / detachment knob 76 is provided corresponding to each terminal.When the wiring attachment / detachment knob 76 is pushed to insert the wiring into the terminal and the wiring attachment / detachment knob 76 is released in this state, the wiring can be pinched and fixed by the force of the spring. Wiring terminals can be connected by so-called one-touch operation.

The pair of transfer output terminals 38a of the first transfer adapter 14 are connected to the non-voltage a contact 78 operated by the relay provided in the transfer output unit 38, and the second transfer adapter is connected by the internal wiring 52. One of the pair of 16 transfer input terminals 40a is connected to the positive power supply line via the pull-up resistor 80 at the transfer input unit 40, and the other is connected to the negative power supply line.

The wiring connection for the transfer input / output is the same for the connection between the transfer output terminal 38a of the second transfer adapter 16 and the transfer input terminal 40a of the first transfer adapter 14 by the internal wiring 54.

The pair of power supply terminals 48a provided on the extension terminal block 74 of the first transfer adapter 14 and the second transfer adapter 16 are connected by the power supply wiring 56, and therefore the first transfer adapter 14 and the second transfer adapter 14 and the second transfer are transferred.

It is not necessary to provide the disconnection monitoring function required for the connection by, and the manufacturing is easy and the cost can be reduced accordingly.

[Delay control of inter-group transfer 1]
FIG. 9 is a time chart showing an embodiment of delay control in which a fire interlocking signal is delayed and transmitted from the second transfer adapter that received the transfer when the fire interlocking signal is received by the first transfer adapter. FIG. 9A shows the reception of the fire interlocking signal by the first transfer adapter 14 of FIG. 3, and FIG. 9B shows the fire transfer signal from the first transfer adapter 14 to the second transfer adapter 16. The transfer is shown, and FIG. 9C shows the transmission of the fire interlocking signal from the second transfer adapter 16.

In the present embodiment, as shown in FIG. 9A, the adapter control unit 32 of the first transfer adapter 14 shown in FIG. 3 has a first channel frequency f1 from the Smoke Detector of its own group G1. When the fire interlocking signal of No. 1 is received at time t1, as shown in FIG. 9B, for example, at time t2 when a predetermined time T1 within 5 seconds elapses, the transfer output unit 38 sends to the second transfer adapter 16. Controls the output of the fire alarm signal.

The adapter control unit 32 of the second transfer adapter 16 that received the fire transfer signal from the first transfer adapter 14 at time t2 is at time t3 when a predetermined delay time T2 longer than the predetermined time T1 has elapsed from time t2. The communication unit 34 is instructed to transmit a fire interlocking signal having a frequency f2 of the second channel to the fire alarm 10 in its own group G2 to output a fire alarm at the interlocking destination. Here, the delay time T2 is set to a predetermined time of, for example, 60 seconds to 50 seconds or less.

When the fire interlocking signal is received by the first transfer adapter 14 in this way, the fire interlocking signal is arranged close to each other by delaying the transmission of the fire interlocking signal from the second transfer adapter 16 which is the side receiving the transfer. When signals are transmitted and received from the first transfer adapter 14 and the second transfer adapter 16 at adjacent channel frequencies f1 and f2, the signals between the two alarm systems become interference waves and interfere with communication. It is possible to surely prevent it from coming out.

Such delay control of inter-group transfer is the same when the fire interlocking signal is received by the second transfer adapter 16. That is, when the adapter control unit 32 of the second transfer adapter 16 shown in FIG. 3 receives a fire interlocking signal of the second channel frequency f2 from the Smoke Detector 10 of its own group G2, for example, within 5 seconds. Control is performed to output a fire transfer signal from the transfer output unit 38 to the first transfer adapter 14 when the predetermined time T1 has elapsed.

Upon receiving the fire transfer signal from the second transfer adapter 16, the adapter control unit 32 of the first transfer adapter 14 instructs the communication unit 34 when the predetermined delay time T2 has elapsed, and the first channel frequency f1. It controls to send a fire interlocking signal to the residential police 10 in its own group G1 to output an interlocking destination fire alarm.

Further, when the adapter control unit 32 of the first transfer adapter 14 and the second transfer adapter 16 receives a fire interlocking signal from another adjacent intergroup transfer device, the same group as shown in FIG. 9 is obtained. Controls the delay of inter-communication.

[Delay control of transfer between groups 2]
FIG. 10 is a time chart showing another embodiment of delay control in which the fire interlocking signal is delayed and transmitted from the second transfer adapter that received the transfer when the fire interlocking signal is received by the first transfer adapter. 10 (A) shows the reception of the fire interlocking signal by the first transfer adapter 14 of FIG. 3, and FIG. 10 (B) shows the fire transfer from the first transfer adapter 14 to the second transfer adapter 16. The signal transfer is shown, and FIG. 10C shows the transmission of the fire interlocking signal from the second transfer adapter 16.

In the present embodiment, as shown in FIG. 10A, the adapter control unit 32 of the first transfer adapter 14 shown in FIG. 3 has a first channel frequency f1 from the Smoke Detector of its own group G1. When the fire interlocking signal is received at time t1, as shown in FIG. 10B, the transfer output unit 38 sends the second transfer adapter 16 to the second transfer adapter 16 at time t2 when a predetermined delay time T2 has elapsed from time t1. Controls the output of fire alarm signals. Here, the delay time T2 is set to a predetermined time of 60 seconds to 50 seconds or less, which is longer than the predetermined time T1 described later, for example.

When the adapter control unit 32 of the second transfer adapter 16 receives the fire transfer signal from the first transfer adapter 14 at time t3, the adapter control unit 32 instructs the communication unit 34, for example, when a predetermined time T1 within 5 seconds elapses. , It controls to transmit the fire interlocking signal of the second channel frequency f2 to the fire alarm 10 in its own group G2 to output the interlocking destination fire alarm.

When the fire interlocking signal is received by the first transfer adapter 14 in this way, the fire interlocking signal is arranged close to each other by delaying the transmission of the fire interlocking signal from the second transfer adapter 16 which is the side receiving the transfer. By preventing the transmission and reception of signals from the first transfer adapter 14 and the second transfer adapter 16 at adjacent channel frequencies f1 and f2 at the same time, the signals between the first and second signal adapters are disturbing waves. This makes it possible to reliably prevent communication problems.

Such delay control of inter-group transfer is the same when the fire interlocking signal is received by the second transfer adapter 16. That is, when the adapter control unit 32 of the second transfer adapter 16 shown in FIG. 3 receives a fire interlocking signal of the second channel frequency f2 from the fire alarm of its own group G2, the predetermined delay time T2 is set. When the elapse has passed, the transfer output unit 38 controls the output of the fire transfer signal to the first transfer adapter 14, and the adapter control unit 32 of the first transfer adapter 14 transfers the fire from the second transfer adapter 16. When the alarm signal is received, for example, when a predetermined time T1 within 5 seconds elapses, the communication unit 34 is instructed, and a fire interlocking signal of the first channel frequency f1 is transmitted to the smoke detector 10 in its own group G1. Controls to output the interlocking destination fire alarm.

Further, when the adapter control unit 32 of the first transfer adapter 14 and the second transfer adapter 16 receives a fire interlocking signal from another adjacent intergroup transfer device, the group is the same as that shown in FIG. Controls the delay of inter-communication.

[Modification of the present invention]
In the above embodiment, the inter-group transfer device 12 is provided with a representative indicator light 50 and an acoustic port 64 on the panel door, but the device housing is configured to be hermetically sealed by screwing or the like, and the representative indicator light 50 and the acoustic port are provided. It may be configured by a closed box not provided with 64. In this case, the effect of being able to check the fire alarm status at a glance disappears, but the sealed structure makes it possible to obtain waterproof performance, making it semi-outdoor like an apartment with exposed stairs and corridors. It can be installed. At this time, it is possible to take measures against dew condensation or the like by making a hole in a specific place of the housing, for example, the lower part and covering the place with a waterproof / breathable material.

(Transfer indicator light)
Although the above embodiment does not indicate the group of the transfer source, in addition to the representative indicator light 50, which of the first transfer adapter and the second adapter housed in the inter-group transfer device is the transfer source. An inter-group transfer device may be provided with a transfer source indicator light indicating the presence or absence.

That is, when the first transfer source indicator light is activated when the first transfer adapter 14 is the transfer source and the second transfer adapter 16 is the transfer source on the panel door of the intergroup transfer device 12. A second source indicator light that is operated on the door is provided.

Therefore, for example, when the number of groups is 2, the group in which the transfer source indicator light is lit is the issue group, so that the issue group can be known at a glance. Also, if the number of groups is 3 or more, there is a report source group in the direction in which the transfer source is displayed, so the report group can be confirmed by following the transfer source of the transfer source indicator light. Can be done.

For example, when a report is issued in the group G3, the inter-group transfer device 12-12 lights the second transfer source indicator lamp on the second transfer adapter 16 side to display the group G2 as the transfer source, and transfers between groups. In the information device 12-23, the second transfer source indicator lamp on the second transfer adapter 16 side lights up to display the group G3 as the transfer source, and the intergroup transfer device 12-34 is on the first transfer adapter 14 side. The first transfer source indicator lamp of the above lights up to display the group G3 as the transfer source. As a result, the group G3 sandwiched between the ascending direction and the descending direction of the reporting source group becomes the issuing source.

Further, as for the transfer source indicator light, the wiring branched from the internal wiring may be connected to the transfer source indicator light. Specifically, the first transfer source indicator lamp indicating the transfer from the first transfer adapter 14 is the rear side of the non-voltage a contact 78 and the second transfer of the output terminals 38a of the first transfer adapter 14. The signal line connecting the negative power supply line side of the input terminal 40a of the adapter 16 is branched and connected to the transfer source indicator lamp. The second transfer source indicator lamp indicating the transfer from the second transfer adapter 16 is the rear side of the non-voltage a contact 78 of the output terminals 38a of the second transfer adapter 16 and the input terminal of the first transfer adapter 14. Of 40a, the signal line connecting to the negative power supply line side is branched and connected to the transfer source indicator lamp.

Further, the transfer source indicator lamp has a first transfer source indicator lamp indicating the transfer of the first transfer adapter 14 and a second transfer source indicator lamp indicating the transfer of the second transfer adapter 16. Alternatively, the transfer source may be distinguished by changing the light emission method such as the emission color of a single transfer indicator lamp.

In addition, it is preferable to provide the transfer source indicator light on the panel door in order to grasp the transfer source at a glance, but the transfer source indicator light is not provided on the panel door and the transfer source is attached to the transfer adapter respectively. An indicator light for indicating may be provided, or the light emission display of the operation indicator light may be distinguished by making the transfer source and the transfer destination different. Further, only the transfer adapter of the transfer source may emit an alarm sound so that it can be identified which is the transfer source.

(Internal wiring)
In the transfer adapter shown in the above embodiment, the internal wiring may be taken out from the front of the transfer adapter, may be taken out from the back, or may be taken out from an appropriate place such as a side surface. Is also good.

When the internal wiring can be taken out from the front, the transfer adapter may be connected to the transfer terminal from the front of the transfer adapter in a state where the transfer adapter is attached to the intergroup transfer device housing.

Further, when the internal wiring can be taken out from the back surface, it is preferable to have a raised bottom structure in which the back surface of the transfer adapter is floated from the inner surface of the device housing which opposes the back surface of the transfer adapter. This makes it possible to secure a space for taking out the internal wiring from the back surface of the adapter and a space for routing the internal wiring. As the raised bottom structure, a structure may be adopted in which a roughly rectangular parallelepiped structure is erected from a position on the inner surface of the device housing corresponding to the vicinity of the side peripheral portion on the back surface of the transfer adapter when the transfer adapter is attached. Of the locations corresponding to the back of the transfer adapter, the approximate rectangular parallelepiped structure should be provided at the positions corresponding to the four corners or at the center of the four sides in order to specify the height of the transfer adapter from the inner surface of the housing. Although suitable, the location of the rectangular parallelepiped structure is not limited to this. Further, although the raised bottom structure is an approximately rectangular parallelepiped structure, an appropriate structure such as a cylindrical structure, a semi-cylindrical structure, or a polygonal prism structure can be adopted to keep the surface inside the device housing facing the back surface of the transfer adapter approximately parallel. ..

(Connection between transfer adapters by the inter-group transfer device circuit section)
Further, in the inter-group transfer device and the transfer adapter shown in the above embodiment, a circuit unit is provided in the inter-group transfer device and transferred without performing a direct wired connection by internal wiring between the transfer adapters. The information adapter and the inter-group information transfer device circuit unit may be connected, and the information transfer adapter may be connected via the inter-group information transfer device circuit unit. The circuit section conducts the connector corresponding to the output section of the first transfer adapter and the connector corresponding to the input section of the second transfer adapter. The multiple connectors corresponding to the transfer input section and transfer output section of the transfer adapter are connectors that protrude vertically from the back of the transfer adapter, and the connector of the circuit section is located at the position corresponding to the connector of the transfer adapter. It is preferable to use a plurality of connectors that project perpendicularly to the back surface of the transfer adapter and the corresponding intergroup transfer device surface, and to make a push-type connection between the connector of the transfer adapter and the connector of the circuit section. This enables electrical connection between the transfer adapters simply by attaching the transfer adapter to the intergroup transfer device.

(Fixed structure of transfer adapter housing)
Further, in the above embodiment, as a structure for fixing the transfer adapter to the device housing, a wall surface is erected from the surface inside the device housing that opposes the back surface of the transfer adapter, and the transfer adapter is sandwiched between the wall surfaces.
