I don't think it would be hard. 'Might be
possible to do with a door/window switch.
Only thing is, you wouldn't know if it was a
power outage, or a break-in. If you could
use another DS7000 solely for this purpose,
that would be great and then you could
record a 'power out' message on it. Of
course, it would be a pain to have to
activate them both every time you leave, but
you might be able to time the learning
phases of them so that they'll learn the
codes from the remotes at the same time, so
one remote could work for two DS7000's.
