Water spray extinguishing system
A water spray extinguishing system is required by building regulations for large stages , among other things . In contrast to a sprinkler system , the pipes are not permanently filled with water, and there are no glass barrels or fusible links to prevent the water from escaping. That is why a water spray extinguishing system (also called a "rain system") is always "triggered". This is done either manually using a push button, for example, or automatically using automatic fire detectors (usually smoke and / or heat parameters). A sprinkler system works selectively, the water spray extinguishing system, however, over a large area in which rapid fire spread is to be expected, since several extinguishing nozzles are always combined into extinguishing areas ("alleys"). When a sprinkler system is triggered, on the other hand, only the sprinkler head that is thermally activated is triggered. The sample assembly site ordinance 2005 and the VStättVen of the federal states require two independent manual trigger points for the extinguishing system, one of which must be located at the fire safety guard's place .
