Claims (1)
検知したガス濃度が警報点を越えるレベルとなつ
たとき検知信号を発生する複数のセンサ回路と、 該複数のセンサ回路からの検知信号の論理積を
とり、前記複数のセンサ回路が検知信号を発生し
ているとき駆動信号を出力する論理回路と、 該論理回路が出力する駆動信号によつて動作さ
れ、警報を発する報知手段とを備える、 ことを特徴とするガス漏れ警報装置。[Scope of Claim for Utility Model Registration] A plurality of sensor circuits that are installed at separate locations in a room and generate a detection signal when the gas concentration detected by each sensor circuit reaches a level exceeding an alarm point, and the plurality of sensor circuits. a logic circuit that takes a logical product of detection signals from the sensor circuits and outputs a drive signal when the plurality of sensor circuits are generating detection signals; and a logic circuit that is operated by the drive signal output from the logic circuit and issues an alarm. A gas leak alarm device comprising: a notification means.
