DETECTOR TESTING METHOD FOR FIRE SENSOR AND FIRE RECEIVER

摘要

PROBLEM TO BE SOLVED: To smoothly perform a detector testing by allowing a fire receiver side to ignore an alarm from a fire sensor which is automatically restored after the end of the detector testing during a prescribed period after the detector testing. SOLUTION: In a fire alarm system in which a fire receiver A is connoted through a monitor line L to a fire sensor B, the fire receiver A side successively confirms the operation of the fire sensor B which is made to issue a test alarm after smoked or heated, and ignores an alarm from the fire sensor B which is automatically restored during a prescribed period.
