PROBLEM TO BE SOLVED: To provide an appropriate logic in an alarm unit such as a fire alarm, at the time of stopping an alarm according to whether it is a true fire or a false report when the alarm is made to be stoppable by a user. SOLUTION: By switching an inspection switch on by means of a push button 3 or a pull cord 6, the alarm is made stoppable by the user. In case of a preliminary fire alarm and a preliminary CO alarm, the alarm is made stoppable. In case of a true fire alarm and a preliminary CO alarm, the alarm is made non-stoppable. In case of a preliminary fire alarm and a true CO alarm by a low concentration alarm, the alarm is made stoppable. In case of a preliminary fire alarm and a true CO alarm by a high concentration alarm, the alarm is made non-stoppable. In case of a true fire alarm and a true CO alarm (low concentration alarm or high concentration alarm), the alarm is made non-stoppable. In case of no fire alarm and a true CO alarm by a low concentration alarm, the alarm is made stoppable. In case of no fire alarm and a true CO alarm by a high concentration alarm, the alarm is made non-stoppable. COPYRIGHT: (C)2009,JPO&INPIT
