IAS Posted May 23, 2011 Share Posted May 23, 2011 Looks like it will be two contacts in series into one EOL circuit. sorry, which panel, what grade etc .......... and any chance of a drawing how you intend to do it?

progear Posted May 27, 2011 Author Share Posted May 27, 2011 sorry, which panel, what grade etc .......... and any chance of a drawing how you intend to do it? Hmmm..... Tricky to put into words, like a set of double doors two contacts across 1 resister then EOL and back to the panel. Its a grade 2 system so all connections will need to be made in appropriate JB's. I plan to series up the tampers i.e. R/S loop and JB switches then sort the 2 contacts across one resister bit.

progear Posted May 28, 2011 Author Share Posted May 28, 2011 Well I haven't gave the G3 option any thought because it's a G2 system but.....correct me if I'm wrong thats why I'm on this forum, the circuit wiring will stay the same but the RS's will need to have magnetic tampering detection the JB's are already G3 so no change there. Is there anything else?

Oxford Posted May 29, 2011 Share Posted May 29, 2011 As far as I can see from this post, it's a grade 2 system so you'll be fine with a single contact.

That is not correct, the grade makes no difference to the amount of contacts. If the shutter requires 2 due to size then it gets 2. We tend to go with a contact and IR beam these days due to shutter being cut or rammed.

Oxford Posted May 29, 2011 Share Posted May 29, 2011 a 3m roller will be fine with1 contact - that's all I was saying. Link to comment https://www.thesecurityinstaller.co.uk/community/topic/31661-roller-shutter-1-or-2-contacts/page/2/#findComment-274198 Share on other sites More sharing options...
Michael Boty Posted June 19, 2011 Share Posted June 19, 2011 I was wondering is there any regs reguarding when a roller shutter is wide enough to need a contact on both sides? I have a job starting soon and the R/Shutters are about 3.3m wide. Over 6 feet wide, 2 Contacts. Measurement gives age of advice but holds well. Not nice to see door wedged open other side to contact and access gained by undesireables.

psycho_49 Posted February 16, 2012 Share Posted February 16, 2012 Not only that but roller shutter contacts have very high tollerence sometimes upto 30 mm therefore over 3mtrs should really be 2 contacts confimed right away, or intruder if lifted from one side..

Ronnie Posted February 16, 2012 Share Posted February 16, 2012 2 contacts confimed right away, or intruder if lifted from one side.. Are you for real? Please tell me you don't work in this industry full time?
