Central Battery System (DualGuard)

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

Due to 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, meaning 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.

Features and benefits:

• Fast commissioning due to the automatic luminaire search function.
• Time-saving automatic function test - the automatic detection of faults in battery strings connected in parallel as well as checking the charging technology, battery strings, battery blocks, insulation monitor and phase monitor function.
• Reduced inspection effort due to CEWA GUARD technology; automatic function monitoring of up to 20 luminaires per circuit.
• Reduction of installation costs - STAR technology and freely programmable mixed operation of the switching types per luminaire in a circuit ensure a reduction in installation costs.
• Light search – the automatic luminaire search function.
• Language – plain text status display on the TFT touch display down to the last luminaire in the local language.
• ISO fault – automatic isolation fault finding and display of the isolation fault according to LED current circuit.
• AC/ AC power source.
