Abstract: Provided is a pressure control system for fire extinguishing equipment, the system including: valves installed at pipes for receiving water supplied from a fire-extinguishing water tank; a digital indicator configured to measure water pressure of the valves or water pressure of the pipes in which the valves are installed and to transmit a signal for abnormality when a value of the measured water pressure does not correspond to a predetermined range; a main control unit configured to transmit a signal for pressure reduction intended for reducing the water pressure of the valves when the signal for abnormality is received from the digital indicator; and a motor operating valve (MOV) installed at the pipes or the valves and configured to reduce the water pressure when the signal for pressure reduction is received.
