Lightning? That's what was going on round here at that time (and
still is).

What type is it?
I have had trouble with the anti-masking protection on Focus
Dual-Tech's and changed most of them out. It actually generates
a tamper alarm in that particular model, but it depends on the
model, how you have them connected up and on the panel, just how
that presents.
