FIRE ALARM FOR HOUSING WITH SIGNAL TRANSMISSION INPUT

摘要

PROBLEM TO BE SOLVED: To provide a new fire alarm for a housing capable of outputting a transmission alarm at the time of receiving a signal transmission input from the other security sensor. SOLUTION: This fire alarm for a housing is provided with a fire detecting circuit 3 for detecting smoke or rising of a temperature, and for outputting an alarm signal, an alarm circuit 7 for outputting an alarm, and a signal processing circuit 4 for controlling the alarm circuit 7 based on the alarm signal. This signal processing circuit 4 which is provided with a signal transmission input terminal T operates the alarm circuit 7 at the time of detecting a signal transmission from an outside security sensor inputted from the signal transmission input terminal.
