Plug a 120 VAC to low voltage DC converter in as if it is a light. Connect a resistor (limits current) in series with a relay to the DC. Connect the relay contacts to an X-10 alarm contact module (if you can't find one, get the newest DAK catalog). Connect the desired lights to respond to the X-10 code generated by the alarm module. Any X-10 experts know if there's any problem with having a light module listen for the alarm module signal? The above has the advantage of mostly using off-the-shelf components which are probably all UL-listed. Soldering is minimal. Scot E.
