The socket is for the PSU for my access control system. It has flex going to a plug plugged into a 13a socket Edited December 15, 2019 by Logan Quote Share this post Link to post Share on other sites
PeterJames 470 Posted December 15, 2019 So its completely mains, so why have you used Fire tough cable to everything apart from the mains? Quote Share this post Link to post Share on other sites
Logan 48 Posted December 15, 2019 (edited) 24 minutes ago, datadiffusion said: Hold up, is the detector mains as well then? No theres a small psu in the base and a mains suitable relay to the sounder. I will make it 24 volt when i get a panel thats why i used fire alarm cable. Feed to future panel will come straight from the fusebox in my shed and the black flex cable will be removed Edited December 15, 2019 by Logan Quote Share this post Link to post Share on other sites

Otherwise he will be just like those other idiots out there that saw a picture of a burglar alarm and now think they are an experienced installer. Mains should be segregated from low voltage cables, not just for safety but to stop ac noise getting onto the low voltage circuits. If you dont point these things out how is somebody supposed to learn. Quote Share this post Link to post Share on other sites

norman 885 Posted December 16, 2019 But ii read it correctly its mains right up to the back of it? So it's all mains in the conduit? Quote Nothing is foolproof to a sufficiently talented fool. Share this post Link to post Share on other sites
datadiffusion 529 Posted December 16, 2019 (edited) I think Pete is right its the little things that make the difference between Johnny Average and a decent installer, I was lucky and, the thing is (and this is why I LOL at the whole 'part time ambo driver' slur) is that for many years, long before I knew anything about ambulances other than you can help yourself to cool drugs and use the blue lights to get between McDonalds branches getting free coffee in the lonely hours between massive car crash jobs, I spent years post C+G exams as a contractor* for a very decent, well respected, do-it-by-the-book firm and learnt just as much from that as on my own, before then, sure I had passed my exams and did rewire a few houses, but stuff you learn on the job like doing conduit neatly and properly, MICC termination, the difference between scruffy junction boxes and doing it right, you don't get taught that at college, and other more complex stuff, I don't know like all the peculiar rules around earthing at special locations that kind of thing. Of course, follow the wrong firm and you'll likely pick up really bad habits, but I was lucky, without that, yes I'd probably convince myself I was as good as anyone else, but I wouldn't really be in the position to tell. After all, if I'd only seen the shiite work we used to encounter without having done it properly myself, I'd probably just assume the shiite was normal! *I should say a contractor with only about 5-6 people on the books, 3 of them directly employed, so we often worked together as a team so that made all the difference for picking stuff up...

When i make the system 24v after i get a fire alarm panel the mains cable will be in fp200 to a fused spur. The black mains can is only temporary while i have a fully mains powered system. ALSO KEEP IN MIND THIS IS ONLY FOR FUN. ITS NOT A PROPER SYSTEM. Im also preparing for the new panel (menvier mf200) no black mains flex anymore. I dont think the system would even be compliment as im using the old colour code cable Edited December 16, 2019 by Logan 1 Quote Share this post Link to post Share on other sites
