Are these used to connect things like shunt locks in the same way as we would use a door loop?

Yep.

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

Do 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

Our YEND74 is extremely popular, and indeed one of our biggest Grade 3 sellers.

 

Main features are:

  • selectable resistors on board for all the main UK intruder panels
  • header supplied to bypass the Magnetic Interference Detection to quickly turn it into a Grade 2 surface contact
  • works on double doors
  • comes with two free packing spacers for awkward frame / doors.
