JasonOfOz Posted April 30, 2018 Share Posted April 30, 2018 On a recent project our Engineers were pulled up for a few issues regarding their cabling: 1. With cable laid in underfloor voids, they didn't use the data matts that were provided 2. They didn't clip their cables to the slab 3. They ran cabling over ductwork, not underneath it. To be fair, it was work done by our 1st fix sub-contractors, rather than our Engineers. However it is actually up to our Team to show the subbies the standards and check that everyone installs to this standard. We are going to put a 1st fix guide together with pictures to show our Teams in future what we expect. Silly question (as i'm not an Engineer), but where do I go to find out about best practice and regulations around running cables for security systems? Thanks. 1 Quote Link to comment Share on other sites More sharing options...

Over ducta seems better incase duct needs to come down What slab? Matts in all directions or they just lashes it anyway possible Quote Link to comment Share on other sites More sharing options...
Simlec Posted April 30, 2018 Share Posted April 30, 2018 All your cabling comes under BS7671 unless it has its own standards like London under ground and the likes. Quote Link to comment Share on other sites More sharing options...

Kaizen Security Posted September 18, 2023 Share Posted September 18, 2023 (edited) I have seen many diffrent installation styles over the years, Clips vs staples, surface run vs hidden, taught vs slack. Personaly I take pride in my 1st fix and cabling and do it properly but that does slow you down. The work I observed with a contractor on a new build housing estate was so slopppy that I pulled him up on it, his justification was that he had targets to hit and they dont pay him enough to give a **** And there seems to be the problem paying **** money to general contractors under pressure to get the job done as quickly as possible. If I had paid good money for a new house I would expect the cable for the window sensor to be run through the upvc window frame and under the window sill not surface run and poorly clipped As mentioned BS7671 is a good place to start for general regs Edited September 18, 2023 by Kaizen Security 1 Quote Link to comment Share on other sites More sharing options...

It still doesn't need to be surface mounted btw..... Quote Link to comment Share on other sites More sharing options...
