を続けることを特徴とする防犯受信回路。A detection circuit is connected between the power lines of the security reception circuit, a security switch is connected to this detection circuit, and the detection circuit has a self-holding type first switching element that responds to the operation of the security switch. An alarm circuit that issues an alarm in response to conduction of the first switching element, and a pulse generation circuit that generates a pulse voltage at regular intervals in response to conduction of the first switching element are connected to the detection circuit. and a recovery circuit having a second switching element that releases self-holding of the first switching element by the pulse voltage is connected between the pulse generation circuit and the detection circuit,
If the security switch is restored when the self-holding of the switching element is released, the alarm is stopped, and if the security switch is not restored, the alarm is continued.
