UNI EN 12845, the Italian version of European Standard EN 12845, sets the design, installation and maintenance criteria for sprinkler systems. It replaces the earlier Italian standards UNI 9489 and UNI 9490. An automatic sprinkler system is designed to detect the presence of fire and extinguish it during the initial stages, or to keep flames under control until they can be extinguished fully using other means. The classic sprinkler system is composed of: a water source, a fire-fighting pump unit, a series of control valves, and a sprinkler circuit. In its basic execution, it consists of: one or more 4", 6", or 8" submerged electric pumps, plus the 4" compensation pump (jockey), if required.

Operating range: from 4 to 160 m3/h.

Working pressure: 16 bar (1600kPa) PN16.

Pumped liquid: clean, free of solids and abrasives, non-viscous, nonaggressive, non-crystallised and chemically neutral, with properties similar to water.

Liquid temperature range: from -15 to 70 °C.
