ADT and Brinks security are a reputable
company that install both wired and
wireless systems. If ADT and Brinks home
security has a home automation rely switch
built in you can use x-10 automation items
with the system. As for triggering an
alarm with the door/window sensors or
motions sensors, no. Now unless you can
program the transmitters into a receiver
that is on the same radio frequency ie:
315MHZ than you can connect that receiver
to the terminals of a hardwired system. So
if an x10 transmitter sends a signal the
receiver will respond and send a
closed/open circuit to the main control
panel. I don't know of any company that
this would work, unless you purchase linear
security products, where you can purchase
there wireless DX system transmitters and
program it to there receiver.
