NRG+ CPS

Reliable, scalable emergency power for complex buildings and critical systems

Our Central Power Supply System (CPS) provides a fully integrated backup power source for emergency lighting, exit signage and life safety equipment. It is designed for large-scale or high-demand environments where safety and compliance must be maintained without compromise.

Built for performance during extended power outages, the system delivers automatic power to critical circuits the moment mains supply fails. Whether you’re operating across a single site or multiple zones, CPS gives you the capacity and confidence to keep people safe and systems operational.

Fully compliant with BS EN 50171, BS EN 62485-2 and BS EN 62034, the CPS solution meets UK and EU standards for central power systems, battery safety and automatic testing.

Core benefits

A high-capacity emergency power system designed for safety, reliability and full compliance

Standards compliant

Meets BS EN 50171, BS EN 62485-2 and BS EN 62034 for emergency power systems, battery safety and automated testing.

High-capacity backup

Manages up to 72 circuits (1440 luminaires), or 256 circuits (5120 luminaires) when SUB units are added.

Automated testing

Function and duration tests are carried out automatically, with results logged for easy review.

Low-maintenance performance

Constant battery and system monitoring reduces the risk of faults and simplifies servicing.

Management of up to 72 circuits (up to 1440 luminaires – max. of 20 luminaires per circuit)
In a project that includes SUBs, you can manage up to 256 circuits (up to 5120 luminaires, with a maximum of 20 luminaires per circuit) on the same unit

CPS compatible emergency luminaires

Our full range of NRG and NRG+ emergency luminaires are fully compatible with CPS systems. Whether you're planning a basic setup or a fully addressable solution with real-time monitoring, we offer fittings to match

NRG Non-Addressable Luminaires

These luminaires operate without individual communication, making them a cost-effective option for smaller or less complex systems. They are tested and controlled in groups via the CPS, offering reliable performance where detailed individual reporting is not required. This approach works well in buildings with uniform layouts or straightforward compliance needs.

NRG+ Addressable Luminaires

NRG+ fittings are fully addressable, meaning each one can be monitored and controlled independently within the CPS network. This allows real-time updates on function, status and faults at fitting level. It gives facilities teams full oversight, supports faster fault diagnosis and simplifies compliance reporting. Ideal for hospitals, multi-storey buildings, or sites with varied use across zones.
