One of the areas people consider least is Emergency Lighting Services. Lighting usually just sits there in the background and because it’s not being used every day, it doesn’t feature foremost in our thoughts.

We wouldn’t want our clients to find out the hard way that the system they had installed all those years ago won’t work when they need it most.
Just like Fire Alarm system maintenance, Emergency Lighting systems must be properly tested, maintained and serviced and this is a legal requirement.

All of our engineers are fully qualified and experienced in the testing of emergency lighting.
Cambridge Electrical are able to carry out 12 month statutory tests on your emergency lighting systems, ensuring that you are fully comply with your insurance and legal requirements.
Our inspection and testing procedures include the following:

  • Luminaire duration testing
  • Cleaning of diffusers
  • Battery charging functional check
  • Supply of test results and/or log books
  • Advice on any improvements required to meet current standards
  • Testing Emergency Lighting

Maintaining your emergency lighting units ensures that all users have sufficient illumination in the event of an emergency to evacuate a building.

The role of the “responsible person” in a premises is to ensure periodic checks are carried out, below we have provided an overview of the testing procedure to give an idea of the frequency and means of testing that should be carried out.

Daily emergency lighting inspection (only for central back-up systems)

This check only applies to emergency lighting systems with one 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 tests (This test can be conducted by the Responsible person or a qualified electrician)

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.

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.

Annually (We strongly recommend that the annual test be conducted by Cambridge Electrical as fully qualified electricians)

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.
