A repeater of fire managing system monitoring detector condition and a fire managing method thereof are provided to minimize degradation of a semiconductor device and to extend lifetime of a detector by discharging the detector through a periodic ground. A repeater(20) of fire managing system comprises a plurality of input parts, a communications part, and a control part. A detector(10) is connected to the input parts. The input parts receive each detection signal from the detectors. The communications part is connected to a receiver(30), and transmits/receives signals. The control part calculates intensity of a current of the detection signal, and receives a warning signal corresponding to a second fire detection signal from the receiver, and outputs a fire warning. |
