Twin duel element PIR's


Recommended Posts

Data sheet says that its a 'Twin duel element detector' and that both sensors have to be triggered to generate an alarm. Is this an approved way of generating a confirmed alarm using a sequential method? Or is it as I'm thinking, just less than a Quad type PIR.

I know that Pyronix were playing about with a detector that did a similar thing and wondered if this Texecom effort was the same idea..

Twin duel eliment detector is a step up from a quad actually.

They are very good detectors, and no, its classed as one zone and is not suitable for confirmed in one - like the optex is.
