Getting too late now! All went exactly as you said until I tried to add a prox tag to my own user. I had taken over the user 01 master, it seems that 01 won't accept a prox tag, I returned that to master and set myself up as 06, but when I tried to set up the tag, the smoke alarm went off!! Something must not be set up correctly, hence stopping fiddling now due to neighbours! The zone for smoke alarm (fire) should be set to normally open shouldn't it? Anyway, so close now, just one tag and the smoke alarm and the system will be functional. Thanks for all the help today hopefully finish tomorrow evening.
