Lighting


Self contained emergency lights with the battery and charger built into the light fi tting are commonly used. In large buildings central systems may be used where the batteries and charger are remote from the light fi ttings.


In some cases an emergency light doubles as an internally illuminated exit sign. However it is not


recommended to simply stick an exit sign over an emergency light fi tting as this will probably reduce the light output and so may become ineffective as an emergency light.


There should be a simple method of testing the


emergency lights without interfering with the normal lighting from the consumer unit (see image below):
