れ警報装置。[Scope of claim for utility model registration] Gas alarm that detects leakage of gas supplied by plugging the power plug into the power outlet of an AC power supply to which loads such as pole transformers and electrical equipment are connected in parallel. In the gas leak alarm device, the gas alarm includes an oscillation circuit and a level detection circuit that detects the output level of the oscillation circuit. The output of the oscillation circuit is led to the power plug, and the level detection circuit detects the output level of the oscillation circuit during a power outage and when the power plug is pulled out from the power outlet, and the output level of the oscillation circuit is led out to the power plug. A gas leak alarm device characterized in that the gas leak alarm device is configured to drive a gas circuit breaker by the detection output of the level detection circuit only when the device is unplugged from the power outlet.
