1SM8 E4A T 400/50 EN 12845 Fire protection automatic pressure station - 8" submersible pump DAB.1SM8 EN 12845

TECHNICAL DATA Stations with fire protection submersible pumps manufactured in accordance with the European standard UNI EN 12845.

EUROPEAN STANDARD EN 12845 specifies the design principles and conditions for the installation and maintenance of fire-fighting fixed sprinkler systems in buildings. It replaces the previous standards UNI 9489 and UNI 9490.

Automatic fire sprinkler systems are designed to detect the presence of a fire and extinguish it at an early stage, or to keep the fire under control until it can be extinguished by other means. A conventional fire sprinkler system includes: a water source, a fire automatic pressure station, a set of control valves and a pressurised water distribution system with sprinklers. The main pump started for fire fighting works permanently until it is stopped manually by pressing the STOP button on the control panel. In the case of circuits with a hydrant, reference is made to the UNI 10779 ( July 07) standard which, in accordance with EN 12845, allows the main pump to be switched off automatically in certain circumstances. Operation of the fire automatic pressure station: under normal circumstances (no water extraction) the system is maintained under static pressure.
