Emergency Lighting

Emergency Lighting Maintenance and Servicing
We provide emergency light testing, periodic servicing and certification as part of our comprehensive maintenance services. Certificates and logbooks are Supplied and all visits are recorded in the logbook.

Finally, to ensure that the system remains at full operational status, essential servicing should be defined. This normally would be performed as part of the testing routine, but in the case of consumable items such as replacement lamps, spares should be provided for immediate use.

Servicing and testing
To test an emergency lighting system you need to simulate a mains power failure on the normal lighting circuit or circuits or individual luminaires. This will force the emergency lighting system to operated and use the battery supply. This can be done manually or automatically.

Manual Testing
You can achieve a simulated mains failure by providing a switch to isolate all lighting circuits or individual circuits or individual luminaires. If manual testing is utilised, the following points should be considered:
In a non-maintained system with a single switch for the whole building or a separate switch used for each circuit you then simulate the mains failure and you have to walk the whole or part of system to check all emergency luminaire are operating correctly. When you restore the mains supply you have to walk the whole or part of system again to check that the emergency lights are recharging.
If all luminaires are individually switched, only a single walk around the building will be needed. However, the test switches could spoil the decor of the building and they must be of a type that is tamper proof. After the tests it is recommended that the performance of the system should be logged.

Automatic Testing
If the costs of an engineer time and the disruption caused by manual testing are excessive, automatic systems should be considered. Different formats are available to match particular site requirements.

BS EN 50172/ BS 5266-8 Emergency escape lighting systems, specifies the minimum provision and testing of emergency lighting for different premises and also additional information on servicing can be found in BS 5266 - Emergency lighting.
The system should include adequate facilities for testing the system condition. These need to be appropriate for the specific site and should be considered as part of the system design. Discussions with the user or system designer should identify, the calibre and reliability of staff available to do the testing and the level of difficulty in performing the test
Discharge tests need to be done outside normal working hours. In buildings that are permanently occupied the test should be phased so only alternate luminaire are tested.
When automatic testing devices are used the information shall be recorded monthly and annually. For all other systems, the tests shall be carried out as described below and the results recorded.
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 correct operation.

Routine inspections and tests
Where national regulations do not apply, the following shall be met.
Because of the possibility of a failure of the normal lighting supply occurring shortly after a period of testing of the emergency lighting system or during the subsequent 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 shall be made until the batteries have been recharged.
The following minimum inspections and tests shall be carried out at the intervals recommended below. The regulating authority may require specific tests.

This is a visual inspection of indicators to identify that the system is in a ready condition and does not require a test of operation.

If automatic testing devices are used, the results of the short duration tests shall be recorded.
For all other systems the tests a short functional test should be carried out in accordance with BS EN 50172 / BS 5266-8.
The period of simulated failure should be sufficient for the purpose of this clause whilst 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.

If automatic testing devices are used, the results of the full rated duration test shall be recorded.
For all other systems a functional test should be carried out as per monthly test but for its full rated duration in accordance with the manufacturer's information in accordance with BS EN 50172 / BS 5266-8.
