ス漏れ警報器。[Claim for Utility Model Registration] A gas detection circuit that detects raw gas by a change in resistance of a gas detection element, an alarm delay circuit, and an initial buzzer avoidance timer circuit based on the capacitor charging time are provided, and the output of the gas detection circuit is delayed in alarm. In a gas leak alarm that is connected to the input of the circuit and the buzzer is connected to the output of the alarm delay circuit,
A relaxation oscillation circuit is provided, its output is connected to the input of the initial buzzer avoidance timer circuit E and the buzzer 42, and the outputs of the gas detection circuit C and the initial buzzer avoidance timer circuit E are connected to the input of the alarm delay circuit F. The capacitance of the capacitor 30 of the initial buzzer avoidance timer circuit E is reduced, and the gas detection element 8 detects raw gas. Therefore, the gas leak alarm is characterized in that the buzzer 42 sounds intermittently.
