Exit and Emergency Lights are a critical part of the life safety system within a building and consists of lighting units and illuminated exist signs used to guide occupants along a safe exit route in the case of an emergency evacuation.
Due to the nature of emergency lighting, it is a requirement that they operate fully automatically and give illumination of a sufficiently high level to enable people to evacuate the premises safely.
For maximum safety, emergency lights should be installed to cover the following areas:
- Each exit door
- Escape routes
- Intersections of corridors
- Outside each final exit and on external escape routes
- Emergency escape signs
- Stairways so that each flight receives adequate light
- Firefighting equipment
- Fire alarm call points
As with all fire safety related equipment, emergency lighting is required to be inspected, tested and serviced at regular intervals in accordance with AS1851 to ensure that all lights are functional in the case of an emergency. To test an emergency lighting system, we simulate a main power failure on the normal lighting circuit or individual lighting units, which will then force the system to operate using the battery supply.
