ELECTRIC CONTROL PANEL FOR THE EN12845 ELECTRIC FIRE-FIGHTING PUMP

8.1 Overview
The control panel for the electric fire-fighting pump installed as a standalone device or with other pressure modules, was
designed in compliance with the requirements of the fire-fighting standard UNI EN 12845.
After suitable modification, the panel is also available in a version for fire-hydrant networks, characterized by the automatic
shutting off of the pump after the pressure has remained constantly above the starting pressure of the pump itself for the length
of time specified by local regulations (the default setting is 20 minutes). For editing follow the instructions described in chapter
8.8.1. Motor overload protection is ensured by high breaking capacity fuses.
