Have been using CK IS215's in domestics for about six years now - without any probs at all really.

I just discovered the optex quad and have installed it in a couple of tricky areas on a recent job, I have now ordered a few more for an install this saturday.

Having seen the coverage pattern on the last install, I was very impressed.

Ive never had a prob with false alarms on my old 215's - but I felt like a change - and now im getting very busy I want a more upmarket detector which is why ive gone for the optex quad (cant remember model no sorry).

What are other peoples thoughts on these detectors (I know about the noisey relay probs of past - but these new ones seem quiet?).

DNS, not the rx40s by any chance are they.

Optex as a rule are amonst the best detectors on the market, they are generally very well built and well thought out with the installer in mind ie lots of knockouts for cables, fixings etc.

We only us their DX40/60 dueltechs but they are top stuff.

Basically as a rule you cant go wrong with Optex

cant remember - got them arriving tomorow - I just know there optex quads - I dont think there pet immune ones, are they the 40QZ's??

I also remember with they curved lense the coverage was spot on - not an area to hide LOL.

Sound like they are RX40QZs

There is a pet version the RX40PZ or something like that.

Pretty certain they are the ones

Ill let you know tommorow - I just wanted to know if anyone has anything bad to say about them before I start fitting them exclusively as a standard detector - obviously im still using dual techs too - (C&K again sorry guys LOL) - but I wanna make sure the optex are ok for standard installs before I switch from the 215's.

I think the dx40s are too expensive just for a dt. Go with the rx40s as a main pir and you cant go far wrong.

The RX40's are not quads just standard dual element PIRs.

Optex call their lens Quad Zone Logic, which misleads people into thinking they are getting a quad (Gardiners even mistakenly had them in the Quad section of their catalogue a few years ago).

These are the ones with the clicking relays and cardboard PCBs. Not for me (but being cheap they've sold a few).
