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.

This means that mixed operation of the continuous light, switched continuous light and standby light modes is possible in one and the same circuit - without any additional data cable. The central battery system can be monitored and controlled via the ACU DG module and the 4.3" or 7" display with non-volatile program memory. The system automatically checks the functioning of all connected devices and emergency luminaires and will issue an alert in the event of a fault.
