Service & Maintenance


Testing and maintaining your emergency lighting units is crucial to ensure that luminares are actually working and that the emergency backup supply is capable to last the full duration required by the standards. The "responsible person" of a business or organisation ensures that the periodic checks are carried out and documented in a fire safety logbook. 


Here at Optimal we carry out periodic inspection and testing as well as repairs and replacements on emergency lighting systems to the latest BS 5266-1: 2016 standard. After the testing is completed, a three page periodic inspection certificate is issued to the client or the 'RP' (Responsible Person).

Maintained and Non Maintained Emergency Lighting Definition:

Maintained Emergency lighting is designed to be lit continuously and will continue to work even in the event of a power failure.

Non-maintained emergency lighting is a luminaire made solely for emergency use. It is designed to come on in the event of a mains power failure, making sure all emergency exit routes are clearly illuminated, but will not be active as your normal day-to-day lighting system.

Emergency lighting is sub-divided into Standby Lighting and Emergency Escape Lighting:


Emergency escape lighting is that part of an emergency lighting system that provides illumination for the safety of people leaving a location or attempting to terminate a potentially dangerous process beforehand. 

Standby lighting is designed to supply illumination in the event of failure of the normal lighting system, so that normal activities in the area may continue.

The New Safety Signs Format:

BS EN ISO 7010 will be the latest version of signage which came into force in January 2015.

Note: Text only signs are not legal and should have already been replaced. BS5499 Pictogram signs (with or without supplementary text) are legal but should only have been used when expanding an installation already incorporating similar signs.
