For over 20 years, Low Smoke Zero Halogen (LSZH) data cables were the popular choice, but this has changed. Data cables are now labelled with a Construction Product Regulation (CPR) EuroClass rating to indicate fire properties. For example, what was LSZH cable will now be labelled EuroClass Eca.
Cables with the much better EuroClass Cca and Bca fire performance are now available.
Cca cables are low smoke and low flame spread. Bca cables are low smoke and zero flame spread.
The BS 6701 standard which covers telecoms cable specification and installation states that, for new buildings and refurbishments, a Cca cable, or better, must be specified for cables permanently installed unless the client specifically asks for a different EuroClass classification.
Cca and Bca cables ares more expensive than Eca so Lynx Networks, in order to continue providing the best value for money and short lead times, may specify Eca cable unless it’s for a new building or a building refurbishment. However, you may prefer to spend more for a better fire rating, particularly if it’s for a public building.
We will make the cable type clear in our quotations, giving reasons and costed options as appropriate.
