Thanks for the reply.

I keep my PIRs in test mode all the time and trigger from that. Hard
wired, no battery problem.

Why do you do that? Do they work better? This is the important bit,
because this is where my problem lies.

I use a home made system, it notifies ME when something happens v ia
pager and tells me exactly what happened. No 'professionals' involved.
Have been using it sucessfully for 20 years.

Mine's not home made...well sort of. It's a kit that I installed
myself. But I bought it specifically because it was not part of a
monitoring setup, and rings me, mobile, pager etc.

(3) My main problem is that the PIRs have two modes. Test and Working.
You stick them on a wall in a likely place and in Test mode you walk
around and they flick on and off to show a "catch".
