- ガスセンサ素子と該ガスセンサ素子と同等の構造を有する比較素子及び2つの抵抗器とともにブリッジ回路を構成している回路構成のガスセンサ回路に対して、前記ガスセンサ素子へ通電して加熱し、該ガスセンサ回路の出力であるセンサ出力が警報判定値に達したときにガス漏れ警報を行うガス漏れ警報器において、
前記ガスセンサ素子への通電開始後の前記ガスセンサ回路の出力であるセンサ出力のピーク値を判定し、該ピーク値が定常状態のエアーベースに対して予め決められた定常警報判定値と同じ極性である場合、前記警報判定値を該ピーク値より絶対値が大きな値に設定するとともに、前記通電開始からエアーベースが定常状態となる所定時間経過後に、該警報判定値を前記定常警報判定値に再設定することを特徴とするガス漏れ警報器。
