うにしたことを特徴とする火災警報装置。[Claim for Utility Model Registration] A plurality of fire detectors for detecting fire are connected to a signal line drawn out from a receiver, and a first switching means is activated based on the signals from the fire detectors to issue an alarm. In a fire alarm device that drives a controller, the receiver is equipped with a reception processing unit that receives and processes signals from each fire detector, and a microcomputer therein, and further includes a reception processing unit that receives and processes signals from each fire detector, and further includes a microcomputer therein, a control unit that determines whether there is a fire and outputs a control signal according to the determination result; a monitoring unit that monitors the control operation of the control unit; and a switching unit that operates when a normal signal is not obtained from the monitoring unit. 2 switching means, and a signal is output to the alarm controller via a signal line connecting the first switching means and the second switching means in series.
