Claims (1)

[Scope of Claim for Utility Model Registration] An analog fire detector that detects and outputs changes in physical phenomena caused by fire in an analog manner, and a plurality of analog fire detectors that are connected and sequentially scanned by the analog fire detector. A repeater that generates an abnormality flag when an analog fire detection signal obtained by A central monitoring board that interrupts a repeater that is generating an abnormality flag and directly reads detection data from the analog fire detector of the repeater, and a central monitoring board that detects a fire phenomenon different from that of the analog fire detector and issues a fire detection signal. a fire detector that outputs a The analog fire detector is installed at the same time as a signal line is connected between the receiver and a central monitoring board, and the central monitoring board interrupts the repeater based on the fire detection signal and address signal from the receiver. , a fire alarm device comprising means for executing an interrupt process for calling in detection data of an analog fire detector near a fire detector that has detected a fire determined in response to the address signal.
