The DualGuard-S central battery system supplies safety and escape sign luminaires with reliable power (230 V AC/220 V DC), automatically checks itself and monitors each of the connected CG-S luminaires (up to 20 per circuit) directly via the supply cable.

Thanks to the STAR technology, the switching mode of each connected CG-S luminaire in a 50 Hz or 60 Hz network can be programmed as required via the central battery system controller.
