By a wide margin, wet pipe sprinkler systems are installed more often than all other types of fire sprinkler systems. Because of their simplicity and reliability, they generally require less maintenance than other types of fire sprinkler systems.
Dry pipe systems are most often used in unheated buildings, in parking garages, or in outside canopies attached to heated buildings. Dry pipe systems differ from wet pipe systems in that the pipes in a dry pipe system are filled with pressurized air instead of water.
Pre-action systems are specialized for use in locations where accidental activation is undesired such as data centers for the protection of computer equipment from accidental water discharge. Deluge systems used for special hazards where rapid fire spread is a concern.
The Reliable Model H Early Suppression Fast Response (ESFR) Sprinkler is designed to respond quickly to growing fires and deliver a heavy water discharge to "suppress" rather than "control" fires. It's commonly used in warehouses.
A fire pump is a part of a fire sprinkler system's water supply and can be powered by electric, diesel, or steam. The pump intake is either connected to the public underground water supply piping, or a static water source.
The Delta Fire pump test nozzle is the quick and accurate method for testing fire pumps. No more and laying out all those hoses. A one-time installation of the Delta fire pump test nozzle is all that is needed.
