Qolsys IQ Panel 2 - intermittent sensor response

[jwcsurety (Jason)]

Are these recessed sensors? And/or are the doors metal?

A similar thread was posted here a while back where the user resolved the issue by moving the sensor installation spot. Ultimately something was hindering signaling in the door header.

This issue seems to be resolved. Moving the sensor out of the 3ft thick header above the door and into the 3 or 4in stud/door frame allows the signal to reach the panel unimpeded. I have not noticed any signal delays as of yet.
