Installation, Testing, and Maintenance in QLD
In a situation of Fire, do you know where to go?
Emergency/Exit Lights have a very vital role in all business establishments.
What are the four categories of emergency lighting?
Importance of Emergency Lighting
Emergency lighting is important to assist occupants to exit the building in an emergency situation.
Section 2.7 of AS/NZS 3012:2010 Electrical installation – Construction and demolition sites, requires sufficient battery-powered lighting to be installed in:
Next to switchboards
This allows for safe access and exit from the area if there is a loss of power and there is not enough natural lighting.
AS 2293.1 allows for an internally illuminated exit sign to perform roles of illuminated emergency exit signage and emergency escape luminaire provided that it meets the requirements of both purposes as set out in the standard.
Emergency Lighting Inspection and Testing
The inspection and maintenance procedures of emergency lighting are detailed in AS/NZS 2293 Part 2, and the process involves:
Confirming no power loss to the system has occurred within the prior 16 hour period
Checking whether all lighting is operational under mains power before testing
Identifying any maintained or non-maintained lighting and verifying functionality
Testing of battery backup (90 Minute Discharge Test)
Cleaning of fittings to ensure they are emitting the required light levels (Lux)
Verify the installed lighting is fit for purpose
Ensure Exit/Emergency lights have returned to normal operation upon test completion
How often should emergency lighting be tested?
According to AS/NZS 2293 Part 2, testing and the required repairs or replacements are required to be carried out at intervals no greater than 6 months.
Emergency lighting should run for a minimum of 90 minutes when discharged, and extended to 120 minutes when batteries are replaced.
How to Test Fittings
Manual Duration Testing
A manually tested system has exit and emergency lights wired to a test timer. They can be very expensive and labour intensive to test, and the results are often inaccurate.
Automatic Testing System
Self-testing Emergency with in-built timer that puts them into duration test mode every 6 months. Or you can have a centrally monitored system to manage the testing and maintenance of the lighting.
