The central battery system for emergency lighting is a centralized power solution designed to ensure the continuous operation of emergency and escape route lighting in the event of a mains power failure. At the heart of the system is the central battery unit, which supplies power to all connected emergency luminaires throughout the facility. This system ensures that corridors, exits, stairwells, and safety-critical areas remain illuminated to guide occupants safely during emergencies. The central battery system features high-performance rechargeable batteries, intelligent charging and monitoring circuits, and automatic self-testing functions to ensure system readiness at all times. It is ideal for large buildings such as hospitals, commercial complexes, airports, and industrial facilities where reliability, ease of maintenance, and compliance with safety regulations are critical.
