A fire sprinkler system is an active fire protection method, consisting of a water supply system, providing adequate pressure and flow rate to a water distribution piping system, onto which fire sprinklers are connected.
Fire hydrant pump systems (also known as fire
pumps, hydrant boosters, fire water pumps) are
high pressure water pumps designed to increase
the firefighting capacity of a building by boosting
the pressure in the hydrant service when mains
is not enough, or when tank fed.
