What is Emergency Lighting?
Legislation requires all occupied buildings to have adequate escape lighting to allow safe exit should mains power fail. Escape and exit routes In the UK must be lit to a minimum of one lux during an emergency.
Emergency luminaires have integral back-up batteries, - continuously charged during normal operation. They power the luminaire for at least 3 hours should power fail. Emergency light output is approx. 10% of normal levels.
Every emergency luminaire must have a green LED indicator to show it is charged and functional.
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.
