Critical applications require a constant and reliable power supply to keep fundamental services running and prevent serious consequences due to interruption or absence of the electrical grid.

The Changeover Panel automatically switches mains electricity from one supply to another, in the event of a fire or mains power failure, to ensure continuity of supply to firefighting lifts and others security system.
