1. Does the entry exit
zone
need to be hardwired, am assuming this
would be front door?Any
other wires required apart from bell box and
power?
No.
The Bell Box, Power, Phone Lead and X10 lead are the only wires
needed
2. Is it possible to have the X10 devices come
on
at timed intervals
to simulate occupation without an alarm event
(arm,disarm etc) being
triggered.
Yes, but it isn't very complex (no
more functionality than you'd get with a traditional timer
switches).
