Guest Mickie D Posted December 26, 2004 Posted December 26, 2004 hope everyone had a great christmas i am in the middle of buying a new system (texecom premier) and wondered what cable was the best to use.... i friend said use BT cable but i dont think thats right is it.. and i have not used it in the past. and it will be 8 core or should i go higher if possible for upgrades etc in the future ? all
Guest simmo Posted December 26, 2004 Posted December 26, 2004 Use 8 core cable this will be fine. Do not use BT cable. Happy Xmas Simmo
CompostCORNER Posted December 26, 2004 Posted December 26, 2004 Yup. 8 core alarm cable is the best, although a pain in the butt for contacts. Alarm cable is multi-stranded meaning it's quite flexible for going around corners. BT cable, I presume you're on about phone cable yes? Well this has a single inner core that degrades very quickly from metal fatigue. In short, bend it around a corner, or twist it into a terminal block or a strip or if you bend it back and forth just a few times, the core will break completely.

Guest Posted December 30, 2004 Posted December 30, 2004 should i buy some plastic trunking and run that along the joists and put the cable in it, or is it ok to run the same run as the mains just as long as they are not tight together ? 35772[/snapback] Ideally as far away as possible, but I wouldn't put them any closer than a few inches. I think 50mm is the recommended minimum. and one last question is should i put the PIR (movement sensors) next to the window but facing the room (not the window) or should i put them in the cornor facing the window but still a nice distance away from the window ? 35772[/snapback] Ooh, plenty of discussion on that one. See this thread.
Guest Mickie D Posted December 30, 2004 Posted December 30, 2004 Ideally as far away as possible, but I wouldn't put them any closer than a few inches. I think 50mm is the recommended minimum. 35777[/snapback] well joists are normally 400MM apart and one is on the one joist and the alarm wil be on the other... so around 300 - 390 they will be apart, would you guys recommend me trunking them in or not needed ?
Guest Posted December 30, 2004 Posted December 30, 2004 Hello, *jumps up and waves*, Ideally as far apart as possible, at least 50mm is recommendeed but I always go for at least a few inches. Don't use trunking, it's not neccesary. Do you want me to come and do it for you?
