Basically they are a moving part that sends a voltage or can be used as a shunt CCT. Moving as in the receiver is "sprung" the receiver is passive. Cisa SRS and a host of others sell them
lawandorder Posted April 13, 2009 Posted April 13, 2009 lawandorderDo you use grade 3 contacts or are you on about the old ones we aint allowed to use anymore? TBH I have never used a grade 3 contact which is probably why I don't understand the problem. I haven't worked full time in the trade for a few years now and the odd bit I do now is small domestics and the odd bit of maintenance to help a mate out. Are grade 3 a bit problematical? (is that a real word)? LOL
jennypatel Posted August 26, 2010 Posted August 26, 2010 Well, I am using the grade 3 doors and I have faced the problem till now. Grade 3 doors are much better then the grade 2 doors and works really well.
