matt6697 Posted November 23, 2015 Share Posted November 23, 2015 (edited) Hi, After inspecting the wiring from a previous installation I've noticed that the person who installed the wiring originally has used an 8 core cable to supply two detectors, and connect the global tamper in series which to me seems acceptable, but they have also spured the 12V supplies from one detector to anther. Would this be acceptable if I left it as it is?, as each zone will still be independent from one another?, just to be honest I've never really come across many cases like this and if it was me I would use a 6 core cable for each detector!

breff Posted November 23, 2015 Share Posted November 23, 2015 No problemo, you are lucky they didnt wire 5 detectors off of 1 8core 1 Quote The opinions I express are mine and are usually correct! (Except when I'm wrong)(which I'm not) Link to comment Share on other sites More sharing options...
timmo66 Posted November 23, 2015 Share Posted November 23, 2015 lol, our old boy used to love 12core. The amount of JBs I'd have to hunt out when upgrading controls and making FSL. Quote Link to comment Share on other sites More sharing options...
BUSTER Posted November 23, 2015 Share Posted November 23, 2015 We bought a company 20 years ago and they thought 12 core was king Quote Any comments / opinions posted are my opinion only and do not represent those of my employer or Company Link to comment Share on other sites More sharing options...

WDT Posted November 24, 2015 Share Posted November 24, 2015 I hope we are not going to start on the cheap 12 core cable, But it did give me a laugh and give me something to read everynight Quote Link to comment Share on other sites More sharing options...
datadiffusion Posted November 24, 2015 Share Posted November 24, 2015 Did a takeover years ago that had Racal detectors all wired in 16 core, extra 4 colours were stripey on white, and it wasn't phone cable.

DavePhelps Posted November 26, 2015 Share Posted November 26, 2015 I went to a job yesterday service by a company with three letters. They have a G2-44 and a Fox PIR!! Now who is going to admit being old enough to remember the Fox ! Quote Link to comment Share on other sites More sharing options...
sixwheeledbeast Posted November 26, 2015 Share Posted November 26, 2015 If it works? Plenty of Racal's, pad's and foil knocking about on maintenance here. Talking of blast from the past check out this playlist... Quote Link to comment Share on other sites More sharing options...

timmo66 Posted November 26, 2015 Share Posted November 26, 2015 ahh, bit of wood in the way there. I have rounded off my fair share of terminal screwdrivers while cutting a little channel into the ceiling, slotting the cable in and filling in...

datadiffusion Posted November 26, 2015 Share Posted November 26, 2015 Was in an 80s new build finishing off today, started Tuesday and there was the remains of an old 2 zone type key system but nothing worth reusing cable wise, redone from scratch. Lol at them bashing multiple holes with a hammer for mains from roof until they worked out where the joist was. Tiny ceiling so not visible without ladder and shelving removed.

secureiam Posted November 27, 2015 Share Posted November 27, 2015 I think its mad when just one core is used for a zone and all the cores are accounted for with power and all the zones using 1 core. its nice and tidy at the panel end very few cables don't get me wrong but it isn't good when things start going wrong with the system.

What you mean one core? You mean one cable daisy chained? data Pirs seem the future really , brought up here before , data bus instead of having to use so many cores or have so many cables, keypads already doing it, makes sense for detectors to Edited November 27, 2015 by al-yeti Quote Link to comment Share on other sites More sharing options...
datadiffusion Posted November 27, 2015 Share Posted November 27, 2015 Thing is it's come and gone before, Risco bus etc... I did think Texe were working on one though? Be ace if it was just 2 wires in, 2 wires out and no polarity etc... with star/spur wiring no issue. Still think it would have the edge over wireless Quote So, I've decided to take my work back underground.... to stop it falling into the wrong hands Link to comment Share on other sites More sharing options...

datadiffusion Posted November 27, 2015 Share Posted November 27, 2015 Why? Why would anyone out for a quick buck choose 'professional' bus DTs at £40 each when they could just slam in a wireless kit?
