Prysmian has released a free guide to emergency lighting standard BS 5266-1:2011, designed to help installers and specifiers choose the right cable for the job.
This latest guide looks at what the changes to BS 5266-1, revised and reissued in November 2011, mean in practice.
The revision gives recommendations and guidance on the design, installation, and wiring cable selection for electrical emergency escape lighting systems. This brings it more closely in line with the British Standard for fire alarms, BS5839-1:2002.
Key issues addressed in the guide:
- A choice between “standard” and “enhanced” emergency lighting cables must now be made for any particular building based upon the recommendations of BS 5266-1 and a fire risk assessment.
- “Standard” cables should satisfy most applications including buildings protected by sprinklers.
- “Enhanced” cables may be necessary for large and complex buildings, particularly if they are un-sprinklered.
- The use of appropriate non-combustible “fire resistant” methods of cable support and fixing are now required.
