Description
Safe disconnection of DC cables using the FFS fire protection switch from Santon by Cergen
The Fire Service Protection Switch (FFS) from Santon by Cergen automatically disconnects all connected DC cables in the Photovoltaic system in the event of a fire or a mains power failure. This ensures that the cable between the FFS and the Inverter is de-energised, allowing fire crews to extinguish the fire safely in the affected area.
