Emergency Lighting Testing
Regular servicing is essential. The occupier/owner of the premises shall appoint a competent person to supervise servicing of the system. This person shall be given sufficient authority to ensure the carrying out of any work necessary to maintain the system in the correct operational mode.
There is a possibility normal lighting could fail shortly after a period of testing and so it is essential to give the emergency lighting system a suitable recharge period, all full duration tests shall, wherever possible, be undertaken just before a time of low risk to allow for battery recharge. Alternatively, suitable temporary arrangements should be made until the batteries have been recharged.
The following minimum emergency lighting testing and inspections shall be carried out at the intervals recommended below (the regulating authority may require specific tests):
Daily emergency lighting inspection (only for central back-up systems)
This check only applies to emergency lighting systems with a central back-up battery system. In this case, there is a daily visual inspection of indicators on the central power supply to identify that the system is operational. No test of operation is required. This test does not apply to emergency lighting with self-contained back-up batteries in each unit (standard emergency lighting).
Monthly emergency lighting testing
All emergency lighting systems must be tested monthly. The test is a short functional test in accordance with BS EN 50172:2004 / BS 5266-8:2004 (also known as a flick test).
The period of simulated failure should be sufficient for the purpose of this test while minimising damage to the system components, e.g. lamps. During this period, all luminaires and signs shall be checked to ensure that they are present, clean and functioning correctly.
Annual emergency lighting testing
A test for the full rated duration of the emergency lights (e.g. 3 hours) must be carried out. The emergency lights must still be working at the end of this test. The result must be recorded and, if failures are detected, these must be remedied as soon as possible. Once completed a certificate can be issued.
