A fire alarm apparatus is provided to prevent out of a battery by generating an alarm signal according to an output voltage of the battery. A fire alarm unit is operated by using a battery(18). A detection unit detects an output voltage of the battery and outputs voltage detection information. A control unit(20) controls an alarm operation and a light display operation on the basis of the voltage detection information of the detection unit. An operational unit operates the control unit in order to input an alarm stop signal. The control unit controls the alarm operation and the light display operation when the detection unit detects an abnormal state of the fire detector. The control unit stops the control of the alarm operation and performs continuously the control of the light display operation according to the alarm stop signal of the operational unit. |
