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.

Puzzle for a wet weekend House was built in 1997 and was pre-wired for alarm system but the 1st owner did not install. When we bought the house in 2001 I hid the ugly cables in electrical surface back boxes. At the time I presumed the 4 cables terminating in the garage were: 1. door switch - cable above front door 2. keypad - cable to side of front door 3. lounge - cable for lounge PIR 4. dinning - cable for dinning PIR I wondered about the cable for the external alarm but never saw any cable in the loft - much of the loft was boarded over. Fast forward to fitting my Elite 24 and I find: 1. door switch - cable above front door is only 4 core and leads to keypad outlet 2. keypad - 8 core cable to side of front door and links to garage cable 3. lounge - 8 core cable as a loop (no end) for lounge PIR and links to garage cable 4. dinning - same 8 core cable as the lounge So that accounts for 2 of the cables terminating in the garage (keypad and lounge+dinning). The 3rd no doubt does go to the loft for the bell. Any ideas what the 4th cable could be? Note: we've now decorated the whole house and no cable has come to light or any indication of a hidden cable. There is no reason while the first owners should bury one cable when they were quite content to have the other cables hanging out of the wall. Alan
