The FireDevice are the end-users for the extinguishing equipment connected to the water supply network. Other elements that serve to fight fires are not listed, as they are no longer part of the drinking water supply. These include the fire water ponds, extinguishing silos, dams, extinguishing shafts, extinguishing water supply, etc.

Sprinkler
Sprinkler systems are used for automatic fire extinguishing in structural facilities where there are many people, where high material assets are to be protected, or where regulations for preventive structural fire protection could not be fulfilled. Sprinkler systems (DIN 14489) essentially consist of fixed pipelines with closed extinguishing nozzles (sprinklers), valve stations (alarm valve) and the water supply (Fritsch et al., 2011).
The collection is usually made as a single point in a building at the end of the line. The type of line to be used depends on local regulations (e.g. hydrant line). Sprinkler systems require per minute and m2 at least 1 l.
