を特徴とするガス漏れコ報装置。In a gas leak alarm device in which a gas detector is connected to each of a plurality of signal lines drawn out from a receiver, the gas detector transmits a gas leak detection signal and a failure signal indicating a state in which gas leak detection is impossible. The signal line is provided for each signal line that receives the transmitted signal, distinguishes between the gas leak detection signal and the failure signal, and outputs the signal. an identification means, a first timer means provided for each identification means that outputs an alarm so as to issue an alarm when the gas leak detection signal outputted by the identification means continues for a predetermined period; and each of the identification means outputs an output. A gas leak alarm device characterized in that a receiver is provided with a second timer means for adding together fault signals and outputting an alarm so as to issue an alarm when the added fault signals continue for a predetermined period of time.
