JP7523640B2 - Disaster prevention system and test method for disaster prevention system - Google Patents

Description

The present invention relates to a disaster prevention system and a method for testing a disaster prevention system in which sensors and system repeaters are installed in a monitoring area, separated by system, messages sent from the sensors are received and processed by the system repeater belonging to the same system, and the processed results are transmitted from the system repeater to a receiver.

Conventionally, in wireless disaster prevention monitoring systems that monitor for fires, multiple wireless sensors are installed in monitoring areas such as each floor of a building or private areas of an apartment building, and are divided into systems, such as by floor. When a wireless sensor detects a fire, it wirelessly transmits a message indicating the fire to a system repeater installed for that system. In addition, when the propagation distance becomes long, radio wave repeaters are installed as necessary, and the message from the wireless sensor is relayed by the radio wave repeater before being transmitted to the system repeater.

The system repeater is connected to the detector line from the receiver, and when it receives a message indicating a fire from a wireless detector, it turns on the relay contacts or switching element to send an alarm current to the detector line and transmits a fire alarm signal to the receiver. When the receiver receives this fire alarm signal, it issues a fire alarm by means of sound, display, etc.

This type of wireless disaster prevention system can eliminate some of the sensor lines that are typically installed in the ceiling, simplifying wiring work and allowing the installation locations of sensors to be determined without being restricted by wiring, etc. Also, system changes such as adding more sensors can be easily accommodated.

However, with such wireless disaster prevention systems, during regular inspections it is necessary to enter the private areas of the home or other buildings where the wireless detectors are installed and use a test device to heat or apply smoke to the sensor section of the wireless detectors to perform alarm tests. However, depending on the facility, it may not be possible to enter the private areas where the wireless detectors are installed without the consent or presence of the user.

To solve this problem, it is conceivable to prepare wireless testing equipment, wirelessly transmit a test signal to a system repeater installed in the exclusive area, and then wirelessly transmit the test signal from the system repeater to a wireless sensor installed in the exclusive area to perform remote testing.

However, system repeaters are often installed in private areas that are separated by, for example, exterior walls. Therefore, even if you enter the common area during regular inspections and transmit a test signal wirelessly from a test device, it may be difficult for the radio waves of the test signal to reach the system repeater installed in the private area separated by an exterior wall, and in order to ensure that the radio waves of the test signal reach the system repeater, it may be necessary, for example, to increase the transmission power of the test device. However, wireless disaster prevention systems generally use specific low-power radio stations that do not require radio station approval, so the transmission power (antenna power) is limited to 10 mW or less, and there remains a possibility that it cannot be guaranteed that the radio waves of the test signal will reach the area.

Furthermore, system repeaters and wireless sensors are installed by system, for example, on a floor-by-floor basis, and it is necessary to move from floor to floor and use wireless testing equipment to test the wireless sensors installed by system, which creates the problem of making inspection of the wireless disaster prevention system time-consuming and laborious.

The present invention aims to provide a disaster prevention system and a testing method thereof that allows testing of detectors installed in separate systems in private areas of a facility to be easily performed across systems by operating in a common area where test workers (inspectors) can freely enter and exit.

[Basic Concept of the Embodiment]
1 is an explanatory diagram showing an outline of a wireless disaster prevention system according to the present invention. The basic concept of the embodiment of the wireless disaster prevention system of the present invention is that a telegram signal (hereinafter simply referred to as "telegram") wirelessly transmitted from one or more wireless sensors 14 installed in a monitoring area, for example, a building 11, is received and processed by system repeaters 12-1 to 12-3 provided for each system, and the processed results of the system repeaters 12-1 to 12-3 are transmitted to a receiver 10 via a system transmission line 16 for notification, and the system repeaters 12 to 12-3 are connected to a test device connection means. Functioning test wiring terminals 15-1 to 15-3 are pulled out by wires and installed in the common areas 11b-1 to 11b-3 of the building 11, and a test device 20 is connected to any of the test wiring terminals 15-1 to 15-3, for example the test wiring terminal 15-1, and a test signal is transmitted from the test device 20 to the system repeater 12-1. The test signal is then transmitted from the system repeater 12-1 to the wireless sensor 14 installed in the exclusive area 11a-1 on the 1st floor, which is the system to which the system repeater 12-1 belongs (the system under its jurisdiction), thereby causing a test to be performed.

In this way, by connecting the test device 20 to the test wiring terminals 15-1 to 15-3 drawn out from the system repeaters 12-1 to 12-3, even if the system repeaters 12-1 to 12-3 are installed in the exclusive areas 11a-1 to 11a-3 separated by an exterior wall or the like, it is possible to transmit a test signal from the test device 20 to the system repeaters 12-1 to 12-3 and reliably perform remote testing of the wireless sensors for each system.

Furthermore, the test device 20 transmits a test signal from the system repeater 12-1 via the receiver 10 to another system, for example the system repeater 12-2 on the 2nd floor, to test the wireless sensor 14 installed in the exclusive area 11a-2 on the 2nd floor, which is another system.

For this reason, even if the system repeaters 12-1 to 12-3 and the wireless sensors 14 are installed in separate systems for each floor, by connecting the test device 20 to one of the test wiring terminals 15-1 to 15-3, the inspector can test all systems from one location without moving between floors, allowing for efficient regular inspection of the wireless disaster prevention system. This is explained in detail below.

[Wireless Disaster Prevention System Overview]
As shown in FIG. 1, each of the first to third floors of a building 11 to be monitored is divided into private areas 11a-1 to 11a-3 surrounded by exterior walls or the like, where designated users such as tenants enter and exit (inspectors of the wireless disaster prevention system cannot enter without permission), and shared areas 11b-1 to 11b-3, such as corridors outside the exterior walls, where people other than designated users can also enter and exit (inspectors of the wireless disaster prevention system can enter and exit as needed). System repeaters 12-1 to 12-3 are installed in the private areas 11a-1 to 11a-3, separated into systems by floor, and are connected to a system transmission line 16 drawn from the receiver 10 and a common power line 18.

In addition, wireless sensors 14 are installed in the private areas 11a-1 to 11a-3 on each of the first to third floors, corresponding to the system repeaters 12-1 to 12-3 for each system.

In the following explanation, when there is no need to distinguish between the system repeaters 12-1 to 12-3, they may be referred to as system repeater 12. Note that a radio wave repeater (repeater repeater) may be installed in order to prevent signals from wireless sensors 14 located far away from the system repeater 12 from failing to reach the system repeater due to attenuation of radio waves.

Each of the system repeaters 12-1 to 12-3 and the wireless detector 14 has its own device ID preregistered (stored). When the smoke concentration or temperature caused by a fire exceeds a predetermined threshold, the wireless detector 14 determines that a fire event has occurred and intermittently wirelessly transmits a predetermined fire information signal, for example, a fire alert message indicating a fire.

The system repeaters 12-1 to 12-3 have the device IDs of the wireless sensors 14 in the same system that are to receive and process messages preregistered, for example, as table information in memory.

By registering the device IDs for the system repeaters 12-1 to 12-3 in this way, when the system repeater 12 receives a message from a wireless sensor 14, it compares the sender ID (the device ID of the wireless sensor 14 that sent the message) contained in the message with the device IDs registered in advance, and if the ID is registered in the system repeater 12, it will process the message as a valid message.

In addition, in Japan, wireless communication between the wireless sensor 14 and the system repeater 12 is based on the standard for specific low-power radio stations in the 400 MHz band, and allows the use of any of 48 channels with a 12.5 KHz band from 426.2500 MHz to 426.8375 MHz.

Therefore, the channel frequency to be used is set to one of the 48 channels available under the 400 MHz band specific low-power radio station standard for the system repeater 12 and the wireless sensor 14. In this case, the channel frequency may be the same on each floor, or, for example, different channel frequencies may be used on adjacent floors to avoid interference.

[Wireless detector]
2 is a block diagram showing the functional configuration of the wireless sensor 14. As shown in FIG. 2, the wireless sensor 14 includes a sensor control unit 22, a wireless communication unit 24 connected to an antenna 26, a sensor unit 28, a display unit 30, an operation unit 32, and a battery power source 34.

The sensor control unit 22 is, for example, a computer circuit equipped with a CPU, memory, various input/output ports, etc. The wireless communication unit 24 transmits messages intermittently in accordance with the standard for specific low-power wireless stations in the 400 MHz band, for example, in Japan.

The format of the message sent by the wireless communication unit 24 is composed of, for example, a preamble (phase correction data), sender ID, message type, data such as smoke concentration and temperature, and an error check code. Among these, the message type indicates, for example, a message indicating the sensor status, a message indicating a periodic report, a message indicating a test result, etc.

The wireless communication unit 24 also receives messages transmitted from the system repeater 12. The messages received by the wireless communication unit 24 have the same format as the transmitted messages, and the message types include test messages that function as test signals.

The sensor unit 28 detects smoke, for example, by a scattered light type smoke detection mechanism, and outputs a smoke detection signal according to the smoke concentration. The detector control unit 22 detects a fire based on this and controls the fire alarm. The sensor unit 28 may be provided with a temperature detection element such as a thermistor, and a temperature detection signal may be output to the detector control unit 22, based on which a fire may be detected. The display unit 30 is equipped with an alarm indicator light that turns on when a fire is detected. The operation unit 32 is equipped with a registration switch, etc.

The detector control unit 22 is a function realized by executing a program, and performs the following control: The detector control unit 22 detects a fire when, for example, a smoke concentration detection signal output from the sensor unit 28 exceeds a predetermined fire threshold, generates a fire alert message indicating the fire, and instructs the wireless communication unit 24 to transmit the message to the system repeater 12 (fire alert control).

When the detector control unit 22 receives a test message including a test command specifying its own ID (its own device ID) via the wireless communication unit 24, it performs a test operation to simulate a fire detection state, for example, to issue a test alert, generates a fire alert message indicating a fire based on the test alert, and instructs the wireless communication unit 24 to transmit the message to the system repeater 12.

In addition, when the sensor control unit 22 detects an event such as a fire recovery or a fault, it generates a message indicating the details of the detected event and instructs the wireless communication unit 24 to transmit the message to the system repeater 12.

[Grid repeater]
3 is a block diagram showing the functional configuration of the system repeater 12. As shown in FIG. 3, the system repeater 12 includes a repeater control unit 36, a wireless communication unit 38 connected to an antenna 40, an operation unit 42, a display unit 44, a test transmission unit 46, a system transmission unit 48, and a power supply unit 50.

The relay control unit 36 is, for example, a computer circuit equipped with a CPU, memory, various input/output ports, etc. The wireless communication unit 38 receives messages from the wireless sensor 14 in accordance with the standard for specific low-power radio stations in the 400 MHz band in the case of Japan, for example, and transmits and receives messages with the test device 20 in accordance with a specified communication standard. As described above, the format of the message received by the wireless communication unit 38 from the wireless sensor 14 is composed of, for example, a preamble, sender ID, communication type, data, and an error check code.

The test transmission unit 46 is wired to a test wiring terminal 15 (test device connection means) installed in the common section, and transmits and receives messages between the test device 20 connected to the test wiring terminal 15. The format of the messages transmitted and received by the test transmission unit 46 between the test device 20 is, for example, composed of a preamble, a sender ID, a destination ID, a command, data, and an error check code, and messages received from the test device 20 include test messages that specify the system to be tested (system number, etc.) and the sensor ID (device ID of the wireless sensor 14), which function as a test signal (test command). On the other hand, messages sent to the test device 20 include test response messages received in response to the transmission of the test message to the wireless sensor 14.

The operation unit 42 is equipped with a registration switch for registering the unit's own ID and the ID of the wireless sensor that the unit is responsible for, and performs various settings required for relay control. The display unit 44 is provided with various indicator lights such as a power light, an alarm indicator light, and an obstruction light. Note that each ID can be registered by any method, including using or not using the registration switch.

The system transmission unit 48 has, for example, a serial transmission function, and when it receives a specific fire information signal, for example a fire alert message, from the wireless sensor 14, it relays and transmits the fire alert message to the receiver 10 via the system transmission line 16 based on instructions from the relay control unit 36 to output a fire alarm. Also, when the relay control unit 36 receives a specific fault information signal due to a malfunction or the like, for example a fault message, from the wireless sensor 14, or detects a fault such as poor communication with the wireless sensor 14, it transmits the fault message to the receiver 10 to output a fault alarm.

In addition, when the relay control unit 36 detects the reception of a test message specifying the other system and the wireless sensor 14 of the other system from the test device 20 connected to the test wiring terminal 15 via the test transmission unit 46, the system transmission unit 48 transmits the test message specifying the other system and the wireless sensor 14 of the other system to the receiver 10.

The relay control unit 36 is a function realized by executing a program, and performs the following control. When the relay control unit 36 receives a fire alert message from a wireless detector 14 in its own system via the wireless communication unit 38, it instructs the system transmission unit 48 to control relay transmission of the fire alert message to the system transmission line 16, and causes the receiver 10 to output a fire alarm. Note that the relay transmission here is not limited to the message being exactly the same before and after the relay.

In addition, when the relay control unit 36 receives a fire restoration message after receiving a fire alert message from the wireless detector 14, it instructs the system transmission unit 48 to control the relay transmission of the fire restoration message to the system transmission line 16, thereby restoring the fire alarm operation of the receiver 10.

In addition, when the relay control unit 36 receives a fault message due to a malfunction or the like from the wireless sensor 14 via the wireless communication unit 38, it instructs the system transmission unit 48 to control relay transmission of the fault message to the system transmission line 16, and causes the receiver 10 to output a fault alarm.

In addition, when the relay control unit 36 receives a test message specifying the sensor ID of its own system from the test device 20 connected to the test wiring terminal 15 via the test transmission unit 46, it instructs the wireless communication unit 38 to control the transmission of the test message to the wireless sensor 14 of its own system.

In addition, after transmitting a test message specifying the sensor ID of its own system to the wireless sensor 14, if the relay control unit 36 receives a test response message indicating a normal test via the wireless communication unit 38, it controls the relay transmission of the test response message to the receiver 10 via the system transmission line 16.

In addition, when the relay control unit 36 receives a test message specifying a sensor ID of another system from the test device 20 connected to the test wiring terminal 15 via the test transmission unit 46, it instructs the system transmission unit 48 to control the transmission of the test message specifying the sensor ID of the other system to the system repeater 12 of the other system via the receiver 10.

In addition, if the relay control unit 36 receives a test response message indicating a normal test within a predetermined time after sending a test message specifying the sensor ID of its own system, it instructs the test transmission unit 46 to relay and transmit the test response message to the test device 20.

In addition, when the relay control unit 36 receives a test message specifying the sensor ID of its own system transmitted by the system repeater of another system via the receiver 10 and transmits it from the wireless communication unit 38, and then receives a test response message indicating that the test was normal within a predetermined time, it instructs the system transmission unit 48 to control relay transmission of the test response message via the receiver 10 to the system repeater 12 of the other system to which the test device 20 is connected.

In addition, if the relay control unit 36 does not receive a test response message indicating a normal test within a specified time after sending a test message specifying the sensor ID of its own system, it determines that the test is abnormal and instructs the test transmission unit 46 to send a test response message indicating the abnormal test to the test device 20.

In addition, if the relay control unit 36 receives a test message specifying the sensor ID of its own system transmitted by a system repeater of another system via the receiver 10 and transmits the test message from the wireless communication unit 38 to the wireless sensor 14 of its own system, and then determines that the test is abnormal if a test response message indicating a normal test is not received within a specified time, it instructs the system transmission unit 48 to relay and transmit a test response message indicating the abnormal test via the receiver 10 to the system repeater of the other system (the system that issued the test command) to which the test device 20 is connected.

After transmitting a test message specifying the detector ID of its own system to the wireless detector 14, the relay control unit 36 may process a fire alert message received within a specified time as a test response message indicating a normal test. The system transmission line 16 may be divided into separate lines as appropriate according to the transmitted message (information) for fire, recovery, failure, test, test response, etc. The power supply line 18 may also be shared with the transmission line.

[Receiving machine]

The receiver 10 is a so-called R type (Record-type) receiver, and as shown in FIG. 4, includes a reception control unit 52, a system transmission unit 54, a display unit 62, an operation unit 64, an audio alarm unit 66, and a reporting unit 68.

The receiving control unit 52 is, for example, a computer circuit equipped with a CPU, memory, various input/output ports, etc.

The system transmission unit 54 connects the system repeaters 12-1 to 12-3 via the system transmission line 16 and the power line 18, receives fire alert messages and fault messages from the system repeaters 12-1 to 12-3 and outputs them to the reception control unit 52, and also receives and transmits (via transmission) test messages specifying the detector IDs of other systems from the system repeaters 12-1 to 12-3, and receives and transmits (via transmission) test response messages, etc.

The audio alarm unit 66 is provided with a speaker and outputs an audio alarm in the event of a fire. The reporting unit 68 outputs a reporting signal to an external device in the event of a fire, causing it to perform a specified operation, etc.

When the reception control unit 52 receives a fire alert message from the system repeater 12 via the system transmission unit 54, it turns on the fire representative light on the display unit 62, outputs a predetermined main sound alarm indicating a fire from the speaker of the sound alarm unit 66, and displays the fire area on the display unit 62, for example, "room XX on XX floor," indicating the system where the fire started and the compartment where the fire started. Furthermore, it outputs a fire alert signal to the outside via the alert transfer unit 68, and performs predetermined alert transfer control, etc.

In addition, when the reception control unit 52 receives a test message specifying another system and its sensor ID from, for example, the system repeater 12-1 via the system transmission unit 54, it instructs the system transmission unit 54 to control the transmission of the test message to the other system, for example, the system repeater 12-2.

In addition, when the reception control unit 52 receives a test response message from the system repeater 12-2 after transmitting a test message specifying another system and its sensor ID to, for example, the system repeater 12-2 via the system transmission unit 54, it instructs the system transmission unit 54 to control the transmission of the test response message to the system repeater 12-1 that is the test source.

The test message and test response message transmitted and received between the system repeater 12 and the receiver 10 may be transmitted using a transmission line provided separately from the system transmission line 16. The receiver 10 may also be a so-called P-type (Proprietary-type). In this case, as described above, the system transmission line 16 is appropriately divided into signal lines such as fire, recovery, fault, test, and test response depending on the message (information) to be transmitted, for example in the case of an R-type, and the system transmission unit 54 transmits signals such as fire, recovery, fault, test, and test response for each signal line. In addition, any multiple pieces of information may be transmitted using a common signal line.

[Test Equipment]
Fig. 5 is a block diagram showing the functional configuration of the test device 20. As shown in Fig. 5, the test device 20 includes a test control unit 70, a test transmission unit 72 connected to a connection plug 74, an operation unit 76, a display unit 78, a storage unit 80, an I/F circuit unit 82 that connects to an external device via a connector port 84, and a power supply unit 86.

The test control unit 70 is, for example, a computer circuit equipped with a CPU, memory, various input/output ports, etc. The test transmission unit 72 transmits and receives messages required for testing the wireless sensor 14, for example by serial transmission, between the system repeater 12 connected via the test wiring terminal 15 and the connection plug 74.

The operation unit 76 is provided with various switches and operation buttons necessary for testing the wireless sensor 14, such as a test start switch, a system designation switch, and an ID designation switch.

The display unit 78 can be provided with the function of the operation unit 76 by providing a touch panel on the display.

The memory unit 80 stores the test results of the wireless sensor 14 performed by the test control unit 70, such as whether the test was normal or abnormal, as well as, for example, the reception strength of the message received during the test, as test history information.

The I/F circuit unit 82 connects to the management server of the manufacturer of the wireless disaster prevention system via the connector port 84, reads the test history information of the wireless sensor 14 from the memory unit 80 of the test device 20, and transmits the data for storage in the management server for use.

The test control unit 70 is a function that is realized by executing a program. When the test system (system number, etc.) and its detector ID are specified using the operation unit 76 and the test switch is operated (test start operation), the test control unit 70 instructs the test transmission unit 72 to transmit a test message specifying the test system and its detector ID to the system repeater 12 via the test wiring terminal 15 connected by the connection plug 74.

In addition, when the test control unit 70 receives a test response message from the system repeater 12 via the test wiring terminal 15 connected by the connection plug 74 after sending the test message, the test control unit 70 controls the display unit 78 to display the test result included in the test response message, that is, a normal test or an abnormal test, and stores the result in the memory unit 80 as test history information.

[Wireless disaster prevention system testing]
1 during inspection will be explained as follows. An inspector carries a test device 20, and when testing a wireless detector 14 installed in the private area 11a-1 on the first floor, for example, the inspector goes to the common area 11b-1 on the first floor and connects the test device 20 by plugging it into the test wiring terminal 15-1 installed there. Note that when inspecting the wireless disaster prevention system, the receiver 10 is switched to a maintenance inspection mode, and even if a fire is determined to have occurred, the main sound alarm, district sound alarm, report transfer control, etc. are stopped. Switching the receiver 10 to the maintenance inspection mode may also be performed from the test device 20.

For example, when testing a wireless sensor 14 installed in the 1st floor private area 11a-1, an inspector who has connected the test device 20 to the test wiring terminal 15-1 sets the 1st floor system number and the sensor ID of the wireless sensor 14 to be tested first in the test device 20 and operates the test switch, and a test message specifying the test system and sensor ID is sent to the system repeater 12-1 via the signal line 17.

The system repeater 12-1 detects that the test system in the received test message is its own system, and wirelessly transmits a test message specifying the ID of the detector to be tested. When the test message transmitted from the system repeater 12-1 is received by the wireless detector 14 with a matching ID, a test report is issued by a test operation that simulates, for example, a fire detection state, and a test response message is transmitted indicating that the test was successful.

When the system repeater 12-1 receives a test response message from the wireless sensor 14 that issued a test alert within a specified time from the transmission of the test message, it relays the test response message to the receiver 10, causing it to display the test alert, and an inspector at the receiver 10 confirms that the wireless sensor 14 issued a test alert normally.

In addition, when the system repeater 12-1 receives a test response message due to a test alert within a specified time from the transmission of the test message, it relays the test response message to the test device 20 connected to the test wiring terminal 15-1, and the test result indicating a normal test is displayed on the test device 20. The inspector can then confirm that the test of the wireless sensor 14 of the specified system and sensor ID was performed normally and that the result is normal, and proceed to test the next wireless sensor 14.

If the system repeater 12-1 does not receive a test response message within a specified time from the transmission of the test message, it determines that a test abnormality has occurred, and relays and transmits a test response message indicating the test abnormality to the test device 20 connected to the test wiring terminal 15-1 for display.

In addition, inspectors can test the wireless sensors 14 installed in the private areas 11a-2 and 11a-3 on the second and third floors with the test device 20 connected to the test wiring terminal 15-1 in the shared area 11b-1 on the first floor.

When an inspector who has connected the test device 20 to the test wiring terminal 15-1 tests a wireless sensor 14 installed in the private area 11a-2 on the 2nd floor, for example, sets the 2nd floor system number and the sensor ID of the wireless sensor 14 to be tested first in the test device 20 and operates the test switch, a test message specifying the other system to be tested and the sensor ID is sent to the system repeater 12-1 via the signal line 17.

The system repeater 12-1 detects from the received test message that the test system is another system, which is 2F, and relays a test message specifying the test system and detector ID to the receiver 10. The receiver 10 receives this test message and transmits a test message specifying the test system and detector ID to the system repeater 12-2 installed on 2F, which is the test system, and the system repeater 12-2 transmits a test message specifying the detector ID. A test alarm is issued by the wireless detector 14 with a matching ID, and a fire alarm message is transmitted.

When the system repeater 12-2 receives a test response message indicating that the test was successful from the wireless detector 14 that issued a test alert within a specified time from the transmission of the test message, it relays the test response message to the receiver 10 to display a fire alert, and also transmits the test response message indicating that the test was successful to the system repeater 12-1 that is the source of the test. The system repeater 12-1 transmits a test response message indicating that the test was successful to the test device 20 connected to the test wiring terminal 15-1, and the test result indicating that the test was successful is displayed on the test device 20, allowing the inspector to confirm that the test of the wireless detector 14 of the specified other system and detector ID on 2F was successful.

[Embodiment in which test wiring terminals are gathered in one place]
FIG. 6 is an explanatory diagram showing an outline of a wireless disaster prevention system in which test wiring terminals are all installed in one place.

As shown in FIG. 6, in this embodiment, the signal lines 17 drawn from the system repeaters 12-1 to 12-3 provided for each system are led into the test wiring terminal 15 installed in the shared section 11b-1 on the 1st floor. The test wiring terminal 15 has three wiring terminals corresponding to the system repeaters 12-1 to 12-3, and by selecting the plug-in of the test device 20, the test device 20 can be connected to one of the system repeaters 12-1 to 12-3 to test the wireless sensor 14 for each system. The other configurations and functions are the same as those of the embodiment shown in FIG. 1 to FIG. 5.

According to this embodiment, inspectors can test the wireless sensors 14 for all systems in the common area 11b-1 on the first floor, where the test wiring terminals 14 for the system repeaters 12-1 to 12-3 are all installed, without having to travel to other floors, further improving the efficiency of the testing process.

In addition, one terminal may be provided in the test wiring terminal 15, and the signal lines from the system repeaters 12-1 to 12-3 to the terminal may be selectively switched and connected using a rotary switch or the like.

[Testing other systems via a system repeater]
FIG. 7 is an explanatory diagram showing an outline of a wireless disaster prevention system that performs tests on other systems without going through a receiver.

As shown in FIG. 7, in this embodiment, system repeaters 12-1 to 12-3 installed in the 1F to 3F systems are connected to each other via a system transmission line 90 for serial transmission. For example, when a test device 20 is connected to the test wiring terminal 15-1 drawn out from the system repeater 12-1, a test message specifying the other system and the sensor ID is sent to the system repeater of the system to be tested, for example, the system repeater 12-2, via the system transmission line 90 without passing through the receiver 10, and the wireless sensor 14 of the other system is tested. The other configurations and functions are the same as those of the embodiment shown in FIG. 1 to FIG. 5.

[Test Equipment Wireless Link]
Fig. 8 is an explanatory diagram showing an embodiment in which a test device is linked to a test wiring terminal of a system repeater by a wireless line. As shown in Fig. 8, in this embodiment, a wireless adapter 92 is connected by a signal line 94 to a test wiring terminal 15 connected to a system repeater 12 via a signal line 17, and a test device 20 has a wireless communication function and transmits and receives messages required for testing wirelessly between the test device 20 and the wireless adapter 92. Here, the test wiring terminal 15 and the wireless adapter 92 constitute a test device connecting means.

The wireless adapter 92 receives a test message wirelessly from the test device 20 and transmits it to the system repeater 12 via the signal line 94, the test wiring terminal 15, and the signal line 17. In addition, a test response message indicating the test result from the system repeater 12 is received by the wireless adapter 92 via the signal line 17, the test wiring terminal 15, and the signal line 94, and this is transmitted to the test device 20 to display the test result.

In this way, the test device 20 and the system repeater 12 are linked by a wireless line via the wireless adapter 92, eliminating the need to attach and detach the test device 20 to the test wiring terminal 15. As long as the test device 20 is within an area where communication with the wireless adapter 92 is possible, remote testing of the wireless sensor can be easily performed by operating the test device 20 from a remote location.

Figure 9 is an explanatory diagram showing another embodiment in which a test device is linked to the test wiring terminal of a system repeater via a wireless line, in which the test wiring terminal 15 shown in Figure 8 has been removed, and a wireless adapter 92 is connected to the system repeater 12 via a signal line 17. This simplifies the configuration by eliminating the need for the test wiring terminal 15. In the case of Figure 9, the wireless adapter 92 serves as the test device connection means.
