The comparator 50 performs a function of notifying the controller 30 of the fire based on voltages applied from the temperature sensors 10a to 10c and the smoke detectors 20a to 20c due to the heat generated in the distribution panel.

The voltage applied from the temperature detectors 10a to 10c and the smoke detectors 20a to 20c is input to the first input terminal (+) of the comparator 50, and to the second input terminal (-) of the comparator 50. The reference voltage set by the resistor is input, and the output terminal of the comparator 50 is connected to the controller 30. The comparator 50 controls the controller 30 when the voltage applied to the first input terminal (+) from the temperature sensors 10a to 10c and the smoke detectors 20a to 20c is higher than the set reference voltage of the second input terminal (−). A high level voltage signal is output to notify the occurrence of a fire, and a voltage applied from the temperature detectors 10a to 10c and the smoke detectors 20a to 20c to the first input terminal (+) is applied to the second input terminal (−). If the reference voltage is lower than the set reference voltage, the controller 30 outputs a signal of a low level voltage to notify that a fire has not occurred.

The controller 30 determines whether a fire has occurred based on a signal input from the comparator 50 and controls the occurrence of an alarm for notifying the operator of the fire when a fire occurs. When the low level voltage signal is input from the comparator 50, the controller 30 determines that a fire has not occurred and performs a control process so as not to generate a fire alarm, and the high level voltage signal is input from the comparator 50. When it is determined that a fire has occurred, the fire alarm is generated by performing a control process for generating a fire alarm.
