The speaker 58 outputs a voice message or an alarm sound from a voice synthesis circuit unit (not shown). The LED 22 displays a warning such as a fire by blinking, blinking, or lighting. Instead of the speaker 48, a buzzer or the like may be used.

  The operation unit 38 is provided with an alarm stop switch 20. The alarm stop switch 20 is effective only when an alarm is displayed with an alarm sound from the notification unit 36 through the speaker 56. If the alarm stop switch 20 is operated during the alarm indicating the interlock source, the alarm sound is stopped and the alarm display is continued. On the other hand, if the alarm stop switch 20 is operated during the alarm indicating the interlock destination, the alarm sound is similarly displayed. Stops and alarm display continues.

On the other hand, the alarm stop switch 20 functions as an inspection switch in a normal monitoring state in which an alarm indicating the interlocking source or the interlocking destination is not performed. When the inspection switch is pressed in this state, a predetermined inspection operation is performed and the notification unit 36 An inspection message indicating the inspection result is output. This check message outputs, for example, “pipe beep fire fire is normal” once when it is normal, “pipe failure” once when the sensor is faulty, and “peep” when the battery is low. The battery power source 40 uses, for example, a predetermined number of lithium batteries or alkaline batteries, and the battery capacity is the entire circuit unit including the wireless communication unit 30 in the residential alarm device 10-1. For example, the battery life of 10 years is guaranteed by the low power consumption.

In addition, an event signal indicating a fire alarm is transmitted to other home alarm devices.

  More specifically, the alarm processing unit 66 indicates the link source from the speaker 58 of the notification unit 36 when the event detection unit 60 detects a fire from the smoke detection signal from the smoke detection unit 16 provided in the sensor unit 34. An alarm sound, for example, “It ’s a fire is a fire,” is repeatedly output, the LED 22 blinks to display an alarm indicating the interlocking source, and an event signal indicating the fire is sent to the antenna by the transmitter circuit 42 of the wireless communication unit 30. 11 to the other home alarm devices 10-2 to 10-3 and the notification broadcast receiver 100.

  Further, the alarm processing unit 62 receives an event signal indicating a fire alarm from any of the other residential alarm devices 10-2 to 10-5 by the reception circuit 44 of the wireless communication unit 30, and is effective in the reception processing unit 62. When the alarm sounds, the alarm sound indicating the link destination is repeatedly output from the speaker 58 of the notification unit 36, for example, “Please confirm that another fire alarm has been activated”, and the LED 22 blinks at the same time. Displays an alarm indicating the link destination.

  When the alarm stop unit 68 detects an alarm stop operation of the alarm stop switch 20 provided in the operation unit 38 during the output of the abnormality alarm indicating the interlock source, an alarm sound from the speaker 58 indicating the interlock source, for example, “pip pip fire. "It is a fire" and the alarm display due to blinking of the LED 22 is stopped, and an event signal indicating the alarm stop is transmitted to the other residential alarm devices 10-2 to 10-3 and the notification broadcast receiver 100.

  In addition, the alarm stop unit 68 stops the alarm sound from the speaker 58 indicating the interlocking destination when detecting the reception of the event signal indicating the alarm stop from another dwelling alarm device during the output of the abnormality alarm indicating the interlocking destination. The alarm display by blinking of the LED 22 is also stopped.

  FIG. 6 is an explanatory diagram showing the format of the event signal used in this embodiment. In FIG. 6, the event signal 46 includes a serial number 48, a transmission source code 50, a group code 52, and an event code 54.

  The serial number 48 is a serial number indicating the order of event signals, and is incremented by one each time an event signal is transmitted. Further, the serial number 48 is generated asynchronously by each of the residential alarm devices 10-1 to 10-3 and the notification broadcast receiver 100. The serial number 48 is for managing the relay processing of the event signal in the communication between the alarm devices, but will not be described in detail because it is not directly related to the present embodiment.

  The transmission source code 50 is a 26-bit code, for example. The group code 52 is, for example, an 8-bit code, and the same group code is set for, for example, the residential alarm devices 10-1 to 10-3 and the notification broadcast receiver 100 of FIG.

  In addition, as the group code 52, in addition to setting the same group code to the same group of house alarms, a reference code common to the house alarms constituting a predetermined group, and a transmission source unique to each house alarm A different group code may be used for each residential alarm obtained from the calculation with the code.

  The event code 54 is a code representing the event contents such as fire and gas leak. In this embodiment, a 3-bit code is used. For example, “001” indicates a fire and “010” indicates a gas leak (for example, Gas leak alarm and fire gas leak combined type alarm), "011" for theft (eg for theft alarm), "100" for alarm stop, "101" for recovery, "110" for inspection, The rest is reserved. Note that the number of bits of the event code 42 can be further increased to 4 bits and 5 bits when the types of events increase, thereby expressing more event contents.

In FIG. 7, when power supply is started from the battery power supply 40 of the residence guard 10-1, initialization and self-diagnosis are executed in step S <b> 1, and if there is no abnormality, the process proceeds to step S <b> 2 and monitoring by the event detection unit 60 is performed. The presence / absence of event detection is checked, and when monitoring event detection is determined, the process proceeds to step S3, and processing corresponding to the detection event is executed.

  Subsequently, in step S4, it is checked whether or not a monitoring event signal has been received from another house alarm device. When it is determined that a monitoring event signal has been received, the process proceeds to step S5, and processing corresponding to the received event is executed.

  FIG. 8 is a flowchart showing details of the detection event response processing in step S3 of FIG.

  In FIG. 8, the detection event response process monitors the fire alarm in step S11. When the smoke detection signal output from the sensor unit 34 exceeds a predetermined fire level, the fire alarm is determined and the process proceeds to step S12. Then, an event signal including a serial number, a transmission source code, a group code, and an event code indicating a fire alarm is wirelessly transmitted to other residential alarm devices and notification broadcast receivers, and then an alarm sound from the speaker 58 is received in step S13. And a fire alarm indicating the interlocking source is output by the alarm display by blinking of the LED 22.

  Subsequently, in step S14, it is determined whether or not there is a fire recovery in which the smoke detection signal from the sensor unit 34 is reduced and the fire is not generated. When the fire recovery is determined, a serial number, a transmission source code, and a group code are determined in step S15. Then, an event signal including an event code indicating a fire recovery is transmitted to the other residential alarm device and the notification broadcast receiver.

  Subsequently, in step S16, it is determined whether or not the alarm stop switch 20 is operated.
