Industry:Fire safety
A water mist system utilizing a single piping system to supply each nozzle.
Industry:Fire safety
A water mist system using automatic nozzles attached to a piping system that contains air that might or might not be under pressure, with a supplemental detection system installed in the same areas as the mist nozzles. The actuation of the detection system opens a valve that allows water to flow into the piping system and discharges through all opened nozzles in the system.
Industry:Fire safety
A water mist system using automatic nozzles attached to a piping system containing air, nitrogen, or inert gas under pressure, the release of which (as from an opening of an automatic nozzle) allows the water pressure to open a dry pipe valve. The water then flows into the piping system and out through any open nozzles.
Industry:Fire safety
A water mist system arranged to discharge directly on an object or hazard in an enclosed, unenclosed, or open outdoor condition.
