My home came with a DSC Impasta Wireless system installed by ADT. It appears that whichever previous owner had this installed ignored the 50+ wired door and window sensors and went with a scaled down wireless covering ground floor doors, 3 windows, and a couple of motion detectors. I’m a home automation guy and I have all of the DSC stuff integrated want the rest of those sensors for my tinkering.

I’m at my wit’s end. I’ve checked all of the places a novice like me would expect to see a security panel; master closet, laundry room, Pantry… I even checked all of the closets for panels and outlet covers for a notch from through-wall wiring. I checked the garages, offices, and even the coat closet. I checked the location of the wireless panel, and took it off of the wall to see if wires were tucked away behind it. No dice. I even checked in the attic, but there’s very deep blown-in insulation so none of the wires are visible. I assume the wall was patched over when the system was abandoned and the years of paint seem to have rendered it invisible.

My next step is an attic crawl to the eaves and dig in the insulation until I find at least one of these sensor wires, and follow it back to wherever it drops. But I would really, really like to not do that. Where should I look that I haven’t checked already? Any other tips for finding these? Does any toner type tool exist that I can buy or rent and connect to the wires to trace them? Thanks.
