Replacement of Central Battery System (CBS) with Self-Contained Emergency Lighting System

To evaluate the replacement of the conventional Central Battery System (CBS) with a self-contained emergency lighting system with built-in batteries for emergency and exit lighting. Comparison of CBS and self-contained emergency lights in terms of cost, reliability, installation, and maintenance. 1) Self-contained emergency lights have built-in rechargeable batteries, eliminating the need for a centralized battery bank and extensive cabling. 2) Reduced installation complexity and lower infrastructure requirements. 3) Individual battery backup provides localized emergency operation in case of power failure. 4) Easier fault identification, testing, replacement, and maintenance. 5) Consideration of battery life, charging time, emergency backup duration, and testing requirements. 6) Assessment of compliance with applicable fire safety and emergency lighting standards. Evaluation of the proposed system based on the building's size, evacuation requirements, and emergency lighting design.
