I have a unused zone and have tried to add two Lynteck TW402 pir's to my existing optima-xm6 panel (all other zones are door/window magnetic connections), without much success Although the tampa part works tha actual sensor does not (not even the led light). I'm thinking that I must be doing something wrong as I've tried two different sensors?
