Cubit Posted September 29, 2013 Posted September 29, 2013 I pushed back to them on the grounds that as long as it was compliant on what grounds were try saying no. Discussions continuing . . .And therein lies one of the problems the inspectorates have brought on.We've covered this before. They want people to do things their way and only their way. And people wonder why this industry is dying.
matthew.brough Posted September 29, 2013 Posted September 29, 2013 And therein lies one of the problems the inspectorates have brought on. We've covered this before. They want people to do things their way and only their way. And people wonder why this industry is dying. They didn't see my point of view at all which was if it is compliant then it isn't for the certification body to dictate how that compliance is met. That said not having the badge is no barrier whatsoever to what we want to do. In many ways it enhances it not having it but in the spirit of doing things properly . . . www.securitywarehouse.co.uk/catalog/
datadiffusion Posted September 29, 2013 Author Posted September 29, 2013 I was going to say, if its not intruder - well, perhaps especially if its not intruder... Whilst I'm here does anyone want to comment on my RA and SDPs? demo SDP.pdf demo RA.pdf So, I've decided to take my work back underground.... to stop it falling into the wrong hands
datadiffusion Posted October 1, 2013 Author Posted October 1, 2013 Well, I did this job today swapping out for an LCD based panel. The two detectors in the initial picture... Wait for it, wired in PARALLEL?!!??!! Or as the job sheet which I found (but sadly haven't got) stuffed on top of the cabinet said 'wire garage in parell' Twisted wires to connect speaker in trunking - no insulation Taped up twisted wire joints in loft Somehow ran out of wires for SAB so joined Strobe to Siren!! (Lets not forget even old panel was PD 2010) Front door contact was Grade 1 without tamper. All from an NSI gold sold as Grade 2X. (Not a cash job or homer). Class and a half.

That is real old school, not seen 2 detectors in parallel deliberately installed for many years, but was used early days of motion sensors. no elephant catchers or quads back then, MWD and Ultrasonic 's were king.Principle was if one detector was tripped by a draft, the other stopped the activation, but a large target would trip both at same time. Could also be used for animals, as long as one did not cover stairs as example, better than stuffing large slug on the zone .

secureiam Posted May 31, 2014 Posted May 31, 2014 I was recently told on a course i attended, that you can have two detectors close together and it comply as long as the paths dont overlap. so some kind of narrow curtain beam pir and a normal pir would give you a no overlap but they wouldnt overlap? whats your take on this?
james.wilson Posted May 31, 2014 Posted May 31, 2014 Yes u can have the same tech without overlap or you can overlap and use a dt securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
