FIG. 6 and FIG. 6 are time charts showing a processing example caused by a battery voltage drop in the wireless residential fire alarm of FIG.

  The emergency radio notification system (hereinafter referred to as the present system) according to the second embodiment of the present invention illustrated in FIGS. 4 to 6 is a fire alarm from the radio notification receiver 2 in the system illustrated in FIGS. The difference is that information transmission to the device 1 is also possible. In this system, a radio notification transmitter / receiver 7 is provided instead of the radio notification receiver 2, and a radio transmission / reception circuit 69 inside the fire alarm 6 is provided instead of the radio transmission circuit 19 inside the fire alarm 1. Is the same as the system of FIG. 1 and FIG. 2 in the circuit configuration, and the description of the same part is omitted.

  Similar to the fire alarm 1 in FIG. 2, when the battery voltage drop is detected, the fire alarm 6 starts timing and sends out the battery deadline notice information from the radio transmission / reception circuit 69 to the radio notification transmitter / receiver 7. Execute. Further, when the first predetermined time comes from the start of timing and the timer circuit 61 counts up, the control circuit 65 activates the alarm circuit 64 and causes the buzzer 63 to sound an alarm for battery exhaustion. Also in this example, the display device and its display control may be performed together with or instead of the buzzer sound as an alarm.

  The control circuit 65 in this system activates the alarm circuit 64 and causes the buzzer 63 to sound an alarm for battery exhaustion, and at the same time operates the radio transmission / reception circuit 69 to cause the radio notification transmitter / receiver 7 to wirelessly transmit the battery exhaustion information. .

  Thus, this system is based on the above-described transmission of the battery exhaustion information from the fire alarm device 6 to the radio notification transmitter / receiver 7. The fire alarm device 6 in this system includes means (for example, a wireless transmission / reception circuit 69) that receives an instruction to stop the alarm for a second predetermined time as a response from the wireless notification transmitter / receiver 7 to the battery exhaustion information. The alarm means exemplified by the control circuit 65, the alarm circuit 64, and the buzzer 63 stops the alarm for the second predetermined time according to the stop instruction received here.

A battery exhaustion notification means for reporting information to the center device 5 via the network. Further, the radio notification transmitter / receiver 7 has a stop instruction receiving means for receiving an instruction to stop the battery low alarm for a second predetermined time from the center device 5 as a response to the notification by the battery low notification means, And a stop instructing means for stopping the alarm issued by the radio alarm device side alarm means for a second predetermined time based on the instruction received in step (b).

  In this way, when the radio notification transmitter / receiver 7 receives the battery exhaustion information from the fire alarm device 6, it issues an alarm indicating that the battery is out of power (preferably a sound is also generated here) The state is reported to the center device 5. An alarm at the radio notification transmitter / receiver 7 is not essential, but is preferably issued.

  The center device 5 needs to transmit such an alarm stop instruction. Therefore, when the center device 5 receives a report from the battery exhaustion notification means, the center device 5 determines a second predetermined time based on the time of the notification, and issues an instruction to stop the battery exhaustion alarm for the determined second predetermined time. It transmits to the wireless report transceiver 7 via the network. If the center device 5 is provided with a clock and a communication interface, such processing can be incorporated into the center device 5 as a program so as to be executable.
