ELECTRIC CONTROL PANEL FOR THE EN12845 DIESEL FIRE-FIGHTING PUMP

9.1 General information
The control panel for the diesel 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.
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).
