Abstract

PURPOSE:To simply obtain a system failure alarming system having high safety with low cost by outputting alarm again only when the alarm is stopped with an alarm stopping switch. CONSTITUTION:A realarm detector 13 is provided in an alarm processing section 1, realarming is made at each set time T of a realarm detector 13 only with the operation of an alarm stopping switch 7 on an alarm panel 3 at a night watchman's room, realarm is given to the night watchmen, allowing to avoid the leaving of an accident as it is. In this case, the night watchmen can completely stop the alarm by operating an alarm stopping switch 7 on a monitor panel 2 in the operation room and the items of failure indicating lamps 5 on the panel 2 can be confirmed.
