What is Emergency Lighting?

UK legislation requires all occupied business and public building escape routes and exits to have a minimum of one lux of light in an emergency situation to allow a safe exit should the mains power fail. In an emergency it is required that all emergency luminaires have power for at least 3 hours and the light output is roughly 10% normal light levels.

The Fire Precautions (Workplace) Regulations 1997 & BS5266 part 1 – require building owners to test emergency lighting systems regularly and maintain them in proper working order.

What is Self-Test? (also commonly known as AutoTest)

Self-Test emergency luminaires have a built in system that automatically carries out routine testing to ensure they are working well and have no system errors; they automatically signal if there is a fault that requires action. By removing the need to test the luminaire manually, Self-Test is highly cost effective.

Maintained and Non-Maintained Luminaires

Maintained luminaires operate as normal light fittings during everyday operation and can be controlled with all other luminaires in the area.

Non-maintained Luminaires

Non-maintained luminaires remain off during everyday operation, only illuminating when mains power fails.
