A Central Battery System (CBS) for emergency lighting is a centralized backup power solution where a single battery bank or power source is used to provide backup power to multiple emergency lights and exit signs throughout a building or facility. Instead of each individual light having its own battery or power source, they are all connected to a central battery system. A large battery bank or power source is installed in a designated location within the building, often in a secure and easily accessible area such as a mechanical room or electrical room. The emergency lights and exit signs throughout the building are connected to the central battery system via a wired distribution network. This network allows the central battery system to provide backup power to multiple fixtures simultaneously. In the event of a power outage or emergency, the central battery system automatically provides backup power to all connected emergency lights and exit signs. This ensures that critical areas such as exit routes, stairwells, and corridors remain illuminated to guide occupants to safety. Central Battery Systems offer a reliable and efficient solution for providing backup power to emergency lighting and exit signs in buildings and facilities. By centralizing the power source, these systems ensure consistent illumination during power outages and emergency situations, enhancing safety for building occupants. Centralizing the backup power source, central battery systems can help reduce energy consumption and maintenance costs compared to systems with individual battery units in each fixture. This can result in long-term cost savings for building owners and operators. The common brands used are CEAG, Awex, Eaton, Teknoware etc.
