SWITCHING FIRE WATCH CONTROL UNIT

A fire monitoring controller of a switchboard is provided to quickly detect a fire accident and automatically extinguish the fire by performing error detection and fire detection functions using a single circuit. A fire monitoring controller of a switchboard includes a first power circuit(10), a CPU(16), a communication module(15), an alarm circuit(17), a display(18), a second power circuit(14), a dual fire monitoring circuit, and a CPU control circuit. The first power circuit generates a first voltage for driving a relay and a solenoid. The second power circuit generates a second voltage from an output voltage of the first power circuit and outputs the second voltage. The second voltage is used to drive the CPU, the communication module, the alarm circuit, and the display. The dual fire monitoring circuit has a dual monitoring function. The CPU control circuit processes a fire detect signal from the dual fire monitoring circuit and a test signal and outputs the processed result.
