PROBLEM TO BE SOLVED: To provide a fire-extinguishing system control board to be easily operated for the view of desired information among the information displayed on the board surface even if the secondary pressure of a valve is reduced or a control valve is closed during the construction. SOLUTION: DIP switches, etc., for setting "the secondary pressure reduction unmonitored" and for setting "the control valve closing unmonitored" are disposed inside the fire extinguishing system control board. When the power supply for the fire extinguishing system control board is started, the setting mentioned above is read, and the reduction of the secondary pressure and the closing of the control valve are put in the "unmonitored" state.
