Re: Humans invisible to heat sensors?

Thanks for all (constructive) replies!  Frank - No, detector not
by-passed, it's one of those systems where you only have the option of
setting Zone A (Ground floor inc exterior doors) or whole house - no
refinements liked auto-bypass on offer.  Zone A  was fully armed from
time they set it to time they switched off and when the break-in
scenario was re-enacted alarm went off immediately every time.  Rocky -
definitely not wearing checkered suits (neighbours saw them running to
car)  Crash - didn't want to bore the world with exactly what was done
when/floorplan but no, not that stupid.  Cheers.
