After being received by 4b and having the house code match determination means 4c confirming the match of the house code, it is input to the signal processing unit 4e and the timer circuit 4f is reset. When the timer circuit 4f is reset, the signal processing unit 4e does not operate the notification control unit 40, and as a result, the emergency signal received by the wireless receiver is separately received via the telephone line lt (not shown). To be sent to

300 → 307 in FIG. 7 and 400 → 409 in FIG. 8 are flowcharts showing operations of the wireless emergency transmitter and the wireless receiver in the wireless emergency notification system.

When the timer circuit times out, the communication control unit of the wireless receiver automatically calls the receiving device (not shown), connects the radio wave line, transmits the received emergency signal, and automatically completes the transmission when the transmission is completed. Although the operation of cutting off the telephone line is performed, in step 409, when the reset switch is operated, the operation of the alarm means is stopped and the state is restored to the initial state.

In the emergency report system using such a two-way wireless transmission / reception system, the configuration can be such that the emergency transmitter, which has transmitted the emergency signal, can also know the operation state of the receiver. As a reception acknowledgment signal for confirming reception of an emergency signal, a notification acknowledgment signal for confirming the transmission operation of the notification control unit via the telephone line, and transmission from a command signal generation provided on the wireless receiver side, these signals are transmitted. On the side of the received wireless emergency transmitter, the sound output of the ringing means may be changed from intermittent output to continuous output, or a corresponding display unit may be provided and turned on.
