Multi-story buildings equipped with fire sprinkler systems may require a large booster pump to deliver sufficient water pressure and volume to upper floors in the event of a fire. Such pumps are often powered by a diesel engine dedicated to this purpose. The engine needs a fuel tank and an automatic controller that will start the booster pump ...
A jockey pump, also known as a pressure-maintenance pump, is a small pump connected to a fire suppression system near the fire pump and is intended to maintain pressure in a fire protection piping system. These pumps recover pressures lost from gradual, slow pressure declines in a system due to temperature changes, trapped air escapement, or ...
Also known as Water Wall. Water flow alarm An audible alarm indicating that one or more sprinkler heads have been activated. "Flow" is often detected by a change in pressure, subjecting these systems to false alarms if anything affects the water pressure feeding the system, however transient. Water mist fire suppression

A fire hydrant, fireplug, firecock (archaic), [1] hydrant riser or Johnny Pump [2] is a connection point by which firefighters can tap into a water supply. It is a component of active fire protection. Underground fire hydrants have been used in Europe and Asia since at least the 18th ...
A fire alarm system is a building system designed to detect, alert occupants, and alert emergency forces of the presence of fire, smoke, carbon monoxide, or other fire-related emergencies. Fire alarm systems are required in most commercial buildings.
A process to perform a water flow test is explained in the model fire codes as published by NFPA (National Fire Protection Association). If a water supply source is considered weak compared to what is required by the sprinkler system design hydraulic calculation, the water pressure can be boosted by means of a fire pump.
