Claims (1)
ガス漏れ検出不能状態を示す障害信号を送出するガス検
出器を接続したガス漏れ警報装置に於いて、 前記ガス検出器の送出する信号が所定時間継続したとき
に出力するタイマ回路と、該タイマ回路の出力により付
勢されて警報を発する警報−路と、前記タイマ回路の機
能を停止してタイマ回路の入力信号により前記警報回路
を直接付勢させるタイマ停止回路とを受信機に設けたこ
とを特徴とするガス漏れ警報装置。[Scope of Claim for Utility Model Registration] In a gas leak alarm device in which a gas detector is connected to a signal line drawn out from a receiver and transmits a gas leak detection signal and a failure signal indicating a state where gas leak detection is impossible, There is a timer circuit that outputs an output when the signal sent by the gas detector continues for a predetermined period of time, an alarm circuit that is energized by the output of the timer circuit and issues an alarm, and a circuit that stops the function of the timer circuit and activates the timer circuit. A gas leak alarm device characterized in that a receiver is provided with a timer stop circuit that directly activates the alarm circuit in response to an input signal.
