Fire pumps are also a critical component integrated into fire trucks and fire boats, and serve a similar purpose boosting water supplies for firefighting hose operations.

The engine needs a fuel tank and an automatic controller that will start the booster pump when it is needed. A small auxiliary electrically-powered booster pump (called a "jockey pump") is often included in the system to maintain the sprinkler pipes at sufficient pressure, without requiring startup of the large diesel engine.
The majority of automatic fire sprinklers operate individually in a fire.

[19] [20] Open orifice sprinklers are only used in water spray systems or deluge sprinklers systems.
