What is an emergency light fitting?
Emergency light fittings include a battery as a backup power source that is continuously charged. Emergency light fittings
can tell when the power has failed and immediately switch to using the backup battery. The battery needs to power
the light fitting for a minimum of 3 hours. To conserve power, the light output from the fitting is reduced, often
to 10% of the normal light output.
What are the different types of emergency light fittings?
Maintained fitting
– will operate as a normal light fitting and be controlled with all the other lights in the area, however
when the power fails the maintained emergency fitting will continue to operate but, at a lower light level.
Non-maintained fitting
– is normally switched off, with its batteries being continuously charged and a green LED showing fully
charged. When the power fails then the fitting switches on using its battery supply. Non-maintained fittings are not part
of the general lighting but are fittings such as emergency exit signs.
All JCC emergency light fittings can operate as a maintained and non-maintained light.
Open areas
The non-obstructed, quickest and safest escape route must be lit to a minimum of 1 lux during an emergency. If the open
area is less than 60m
2
and isn’t part of an escape route then emergency lighting isn’t required, however the exit doors
for the emergency escape route must have signs or an emergency bulkhead light.
An escape route such as a designated corridor
An escape route must be unobstructed and lit to a minimum of 1 lux during an emergency.
Stairwells
Due to increased hazards, these areas need to be lit to a minimum of 2 lux during an emergency.
