"I have an alarm system now. I'd like to
get rid of the control panel and put in an
x10 system."
You're braver than I am. I wouldn't think
of removing my existing system and
replacing with an X10 one. What I have is
reliable, dependable, and affordable.
Most decent alarms do have a alarm out that
will trigger a power flash module, however.
I had my installers run a wire for me to
connect to a power flash module to flash my
lights when the alarm is triggered.
FYI.. Many of the well known commercial
alarm companies use proprietary control
panels requiring you to use the their
choice of monitoring service. They can
quickly recover their giveaway installation
price with their overpriced monitoring
fees. Ask and get in writing that the
system will allow you to chose your own
monitoring service!
I do not recommend using any alarm system
without a monitoring service. Many cities
have fines for false alarms.
