Hi
I now have my Kidde SM120X Smoke Detector module, purchased from
www.galesburgelectric.com $7.23 each.
For those interested I have scanned the instructions and Label from the unit, Check out
http://tinyurl.com/4ax3ahgI purchased 3 for less than $27 inc Shipping. This Module is the ideal interface between the DS10a and a 120v hard wired smoke detector, I have not managed to try them yet as I haven't received my shipment from X10.
