Learn MoreIn a centrally supplied system, the emergency and exit lights share a common power supply from a central battery unit. In its basic form, the central battery system monitors the mains voltage, maintains the charging of the batteries and supplies power to maintained luminaires in the normal mode.
A Central Battery System (CBS) is essentially a large set of batteries at a single central location. In the event of a mains failure in the building, the batteries are used to provide power for emergency lighting purposes.
If a maintained central battery system is used the emergency lighting will be on all the time ,whatever the status of the mains both generally or locally, which means no local sub-circuit monitoring is required.
Our addressable central battery units can also be connected to the building management system, making the monitoring and testing of emergency lighting a part of the property management. The system is self learning, with the possibility for automatic configuration during commissioning.
Central battery systems provide low voltage AC power (typically 24V, 48V or 110V AC) whilst mains to the system is healthy, and low voltage DC when mains fails. The battery voltage selected will depend upon the number of luminaires, the rating, their type and their distance from the central system.
A non-addressable central battery unit is suitable for small or mediumsized properties where the monitoring and maintenance operations of the luminaires connected to the system can be performed manually. All the operations related to the use of the system, such as testing the battery operation, can be performed through the system's user panel.
