When it comes to emergency lighting and essential backup power, Central Battery Systems offers a reliable and efficient solution. These systems play a vital role in modern building safety infrastructure, particularly in commercial and industrial environments. At Uninterrupted Power Solutions, we design, install, and maintain Central Battery Systems to ensure full compliance and dependable performance.

Here are five important facts about Central Battery Systems that every facilities manager, electrical contractor, or building owner should know:

1. They Provide Centralised Emergency Power

As the name suggests, a Central Battery System delivers power from a centralised battery bank. If mains power fails, the system automatically activates to supply emergency lighting and other critical safety systems across the building. This approach differs from self-contained emergency lights, which rely on individual batteries. By centralising the power source, maintenance becomes simpler and system monitoring more effective.

2. Central Battery Systems Must Comply with BS EN 50171

All Central Battery Systems used for emergency lighting must meet the requirements of BS EN 50171, the British Standard governing central power supply systems. This includes specifications for battery performance, system durability, and charging characteristics. At Uninterrupted Power Solutions, every Central Battery System we design and install adheres strictly to this standard to guarantee reliable operation in an emergency.

3. Centralised Maintenance Cuts Time and Cost

One of the key advantages of Central Battery Systems is simplified maintenance. With all batteries housed in a single location, regular testing, inspections, and battery replacements are far easier and faster than managing individual emergency lights throughout a building. This centralised approach can significantly reduce long-term maintenance costs, especially in large facilities such as hospitals, schools, and commercial offices.

4. Battery Choice Affects Performance and Longevity

Central Battery Systems can be built using various battery technologies, including VRLA (Valve Regulated Lead Acid) and NiCd (Nickel-Cadmium). The best option depends on several factors, such as available space, ambient temperature, and the expected lifespan of the system. VRLA batteries are widely used due to their sealed construction, low maintenance, and cost-effectiveness. Uninterrupted Power Solutions always selects battery types based on the demands of the application and compliance requirements.

5. They Improve Safety and Regulatory Compliance

Installing a reliable Central Battery System not only ensures emergency lighting stays operational during power failures but also helps meet building safety legislation. Illuminated escape routes and emergency signage are critical for safe evacuation. A properly maintained Central Battery System helps protect occupants and ensures compliance with fire safety and emergency lighting regulations.
