arfur mo Posted June 20, 2007 Share Posted June 20, 2007 This is a pic of what I found above the false ceiling while I was commissioning a system installed by a subby! another case of a few more seconds and he could have done the job properly, i would be a little verbous as you could immagine towards this twerp. i might also take the time to exsplain to him that most if not all manufacturer's, do not recommend running detection in the same cable as sirens . regs alan If you think education is difficult, try being stupid!!!!

arfur mo Posted June 20, 2007 Share Posted June 20, 2007 xxxx are you telling me yet again that ive been doing it wrong for the last twenty years or did you mean to say speakers and data cables hi Angus, no matey, for as long as i can remmember it was no bells/sirens (including speakers) to be run in with zone wiring, even conventional CCT wiring zone cables, and way before data ever crept into alarms - i'm talking relays and transistor technomology here. it could cause a false indication, also more for engineers safety. ever touched a 'pair' feeding a ringing internal bell? three cherries and a lots of swearing guarenteed, in a siren with an operating strobe inadvertantly touching the 12 volts supply could actually burn you. regs alan If you think education is difficult, try being stupid!!!!

tinnitus Posted June 20, 2007 Share Posted June 20, 2007 im working in a little shop installing security at the mo .old trunking running everywhere, not nice. its also quite untidy. the previous owner had left a drum of mains cable in a corner, i thought nothing of it and it wasn't in my way so i didn't touch it. the new owner and my customer was moving sockets and was trying to trace cables from the fuse board, guess where the cable wired into the 30 amp fuse went? that's right, the cooker, only joking it was the drum of cable in the corner, live and 30 amps!

It's to stop the scroats nicking it to weigh it in. They'll only try it the once. Growing old is mandatory, growing up is optional Link to comment Share on other sites More sharing options...
