連動型ガスもれ警報器。Consists of a gas alarm circuit including a buzzer circuit that sounds different buzzers for two gas leak notifications and a cutoff valve operation notification, and a cutoff valve control circuit that drives and controls the gas cutoff valve based on the alarm signal from this alarm circuit, The cutoff valve control circuit includes a trigger circuit and a charging circuit that are activated by the alarm signal, a gate circuit that supplies power from the charging circuit to the gas cutoff valve in response to a trigger signal from the trigger circuit, and a gate circuit that controls the operation of the gas cutoff valve. a control circuit that detects and disables the l-trigger circuit and controls the buzzer circuit to notify the shutoff valve operation, and the gas shutoff valve is a switch that opens and self-maintains when activated. A gas leak alarm interlocked with a shutoff valve, characterized in that a gas leak alarm is provided in series with its power supply terminal.
