警報器を備えたガス警報器において、前記ガス警
報器の通電当初に一定時間作動するタイマを設け
、このタイマの作動中に前記ガス検知素子へ高レ
ベルの電圧を供給し、前記タイマの作動が停止し
たとき低レベルの低電圧を供給する定電圧回路を
設けたことを特徴とするガス警報器。 In a gas alarm equipped with an alarm that issues an alarm signal upon detection of a gas detection element, a timer is provided that operates for a certain period of time when the gas alarm is first energized, and during the operation of this timer, a high level signal is sent to the gas detection element. 1. A gas alarm device comprising: a constant voltage circuit that supplies a low level voltage when the timer stops operating.
