PURPOSE:To permit to effect a proper conservating measure at an optimum time by a method wherein the movement of a pressure switch is sent into the automatic inspection device to indicate a pumping condition corresponding to a pressure switch pattern in accordance with the pumping condition memorized already. CONSTITUTION:The ON, OFF pattern of the pressure switch 10 is memorized into the memory of the automatic inspection device 11 of the pump and when a command to effect the automatic inspection of the pump is outputted from the automatic inspection device 11, a fire pump control board 12 conducts and energize a motor 3 and the motor 3 operates the pump 2 for a short time necessary for the automatic inspection of the pump 2. The condition of ON, OFF of the pressure switch 10 during the operation of the pump is sent to the automatic inspection device 11 and the pumping condition is indicated, therefore, the proper conservating measure may be effected at an optimum time. |
