Emergency Lighting systems

Emergency Lighting

Emergency Lighting is used for lighting areas in the event of a power failure when it is essential to quickly locate fire fighting equipment and identify exit routes from the premises. 
Is usually required to operate automatically and give illumination of a sufficiently high level to enable persons of all ages to evacuate the premises safely.

 A note on Terminology:

Non-maintained - The emergency light is only illuminated on interuption of the mains power supply.

Maintained - The emergency light uses the same source for both mains, which is usually switched, and in emergency mode.

Sustained -The emergency light has a seperate light source for both mains and emergency mode and is often switchable.
