Patent ID: 8068026

Claim:
A periodic tester for monitoring an electrical fire pump system comprising: a) the periodic tester being housed in a cabinet; b) the periodic tester having a periodic time clock in order for the periodic tester to test at a given interval of time mounted in a cabinet housing; c) a fire pump controller being housed in a fire pump controller housing; d) the periodic tester and the fire pump controller being electrically interconnected; e) an electric motor being connected to a fire pump through a coupling; f) a sprinkler system interfacing with the fire pump controller; g) the fire pump being connected to the sprinkler system; h) the fire pump providing power for the sprinkler system; i) the periodic tester interfacing with the electric motor; j) a pilot pipe being connected to the sprinkler system; k) the pilot pipe communicating with the fire pump controller; l) the fire pump controller having a power on/off pressure switch; m) the power on/off pressure switch communicating with a contactor assembly with a contactor coil and a contactor switch; n) the pilot pipe communicating with the power on/off pressure switch; o) the pilot pipe having at least one orifice union to minimize pressure surges to the power on/off pressure switch; p) the periodic time clock communicating with the power on/off pressure switch, either directly or indirectly through a solenoid valve which interacts with the sprinkler system; q) a circuitry to illuminate a failure to start light being housed in the cabinet of the periodic tester; r) an exterior of the cabinet of the periodic tester having the failure to start light which is illuminated if the fire pump fails to start during a testing cycle; s) a circuitry to illuminate a coil failure alarm light being housed in the cabinet of the period tester; t) the exterior of the cabinet having the coil failure alarm light which is activated if the contactor coil is responsible for the failure of the fire pump to start; u) a circuitry to sound an audible alarm being housed in the cabinet of the periodic tester; v) the exterior of the cabinet having the audible alarm which sounds if the fire pump fails to start during a testing cycle; and w) the exterior of the cabinet having a reset button which silences the audible alarm and extinguishes the failure to start light.
