A fire pump is a part of a fire sprinkler system's water supply and powered by electric, diesel or steam. The pump intake is either connected to the public underground water supply piping, or a static water source (e.g., tank, reservoir, lake). The pump provides water flow at a higher pressure to the sprinkler system risers and hose standpipes. A fire pump is tested and listed for its use specifically for fire service by a third-party testing and listing agency, such as UL or FM Global. The main code that governs fire pump installations in North America is the National Fire Protection Association's NFPA 20 Standard for the Installation of Stationary Fire Pumps for Fire Protection.

A periodic tester to determine the readiness of a fire pump system interfaces with a fire pump controller, an electric motor, and a sprinkler system. The fire pump controller has a power on / off sensor which interfaces with an electric motor which starts the fire pump to provide water to the sprinkler system. The power on / off system has a contactor coil as a component. The periodic tester targets two of the main components of fire system failure: the power on / off sensor and the contactor coil. The periodic tester may be retrofitted to existing systems and interface either directly or indirectly with the power on / off sensor to accommodate both systems that have a solenoid valve and those that do not. The periodic tester is designed to attempt to start the system only once during a set cycle. Any failure to start is displayed through audible and visual alarms.

Method for Controlling the Discharge Pressure of an Engine-Driven Pump
ActiveUS20080292472A1Electrical controlOperating means/releasing devices for valvesIdle speedEngineering
A system for controlling the pressure output of an engine-driven centrifugal fire pump includes a discharge pressure sensor mounted in the discharge line of the pump. A governor varies the rpms of the engine in response to pressure changes detected by the discharge pressure sensor. If the pressure in the system is higher than the desired output pressure when the engine is running at its idle speed an electronically controlled hydraulic relief valve responsive to the discharge pressure sensor operates to relieve the excess pressure in over pressure situations. If the pressure in the system is lower than the desired output pressure when the relief valve is fully closed, the engine speed is increased.
