器。A gas detection circuit B which connects the gas detection element 10 to its input and outputs a low level when it does not detect gas and a high level when it detects gas, and a buzzer circuit C which operates only when it outputs a high level. Similarly, a relay circuit that opens and closes the contact 2-1 connected in series with the electric appliance 4, and a reset switch circuit E that operates the relay 2 in the circuit when it is not operated are provided, and the output of the gas detection circuit B is set. The buzzer circuit C and the relay circuit are connected, and the reset switch circuit E is connected to the thyristor 25 of the relay circuit, and the gas detection element 10
When gas is detected, the buzzer circuit C operates and the relay circuit operates to open the contact 2-1, and then by turning on the reset switch circuit E, the contact 2-1 is closed and the electric appliance 4 is operated. A gas leak alarm featuring:
