How often should an Emergency Lighting system be tested?

The following minimum inspection and tests should be carried out at the intervals recommended below.

Daily Emergency Lighting Inspection

This interval specifically applies to central battery source emergency lighting systems.  In this case a visual inspection of the indicators on the central power supply to identify that the system is operational.  No test of the system operation is required.

Monthly Emergency Lighting Testing

All emergency lighting systems should be tested monthly.  This is a short functional test in accordance with BS EN 50172:2004 / BS 5266-8:2004.

The duration of the test should be sufficient to ensure that the luminaire operates correctly, whilst minimising any damage to the system components, e.g. Lamps, Battery.

It is important to note that the entire system doesn't have to be tested at the same time.  The system can be tested in sections, over a testing schedule, so long as each luminaire is tested each calendar month.

Annual Emergency Lighting Testing

The annual test should be a full rated duration test to ensure that the emergency lights are still working and producing the acceptable level of light at the end of the test.  So for example if a luminaire is rated for a 3 hour duration, then after 3 hours in an emergency situation the light should still be lit.

It is worth noting that this full duration test should be completed at a time of low risk of an emergency situation so that the batteries have sufficient time to recharge.
