A gas leak alarm device comprising: a comparison/discrimination circuit that compares and discriminates signals; and an alarm circuit that issues an alarm based on the output signal of the comparison/discrimination circuit. (2) A claim characterized in that the alarm circuit issues an alarm when the comparison and discrimination circuit detects that gas is present and determines that gas is being supplied based on the detection signal and the activation signal. Gas leak alarm device according to item 1. (3) The alarm circuit issues a first alarm when the comparison and discrimination circuit detects the presence of gas and determines that gas is being supplied based on the detection signal and the activation signal, and when the presence of gas is detected. Claim 1 characterized in that the second alarm is issued when it is determined that gas is not being supplied.
Gas leak alarm device as described.
