Claims (1)

[Scope of utility model registration request] A plurality of detector connection terminals that are pulled up to the power supply voltage via a resistor, and a common ground terminal that commonly connects the other ends of the switch parts of the detectors that have one end connected to one of the detector connection terminals. A push button connection terminal that connects one end of the push button switch section to the detector connection terminal of the device, and a push button connection terminal that connects the other end of the push button switch section, and a detector that is provided corresponding to each of the above detector connection terminals and connected to each of the detector connection terminals. An alarm sound output section that operates when the switch section or push button switch section of the sensor is turned on, and a detection signal that is captured when the switch section of the detector connected between the detector connection terminal and the common ground terminal is turned on, and the detection signal is output. In the signal processing circuit for notification, the signal processing circuit is equipped with a detection output section that stops sending out the detection signal when the push button switch section is turned on, and the push button switch section connects a parallel circuit of a capacitor and a resistor in series to the push button switch. A notification signal processing circuit characterized in that it is configured as follows.
