Abstract
A microprocessor based jockey pump controller for controlling operation of a jockey pump used to maintain pressure within a fire pump system. The controller includes an electronic circuit board having a microprocessor mounted thereon, and a solid state pressure sensing device for monitoring a current level of the pressure. The sensing device is connected to the board for transmitting to the microprocessor an electrical signal indicative of the current level of the pressure. The microprocessor compares the received signal to predetermined pressure thresholds for selectively starting or stopping the jockey pump.
