Sprinkler alarm valve

A sprinkler alarm valve, or fire sprinkler valve, prevents a reverse flow of water from the installation into the fire-pump room, but in case a fire sprinkler is activated (opened) due to fire, the sprinkler alarm valve will open and permit water flow into the system.

Sprinkler alarm valves prevent a reverse flow of water or air pressure from the installation into the fire-pump room. In case a fire sprinkler is activated (opened) due to fire, the sprinkler alarm valve will open and permit water flow into the system and a pressure switch gives a signal to activate the fire-pump.

There are different types of sprinkler alarm valves that need to match the fire sprinkler installation (wet pipe system, dry pipe system, deluge system, etc.). Almost all sprinkler alarm valves are noted by a listing authority such as VdS, FM, UL etc.

Grundfos supplies fire pumps for water supply as part of approved fire sprinkler systems for industrial and commercial fire protection.
