Hello, long time since this thread was started but I too have an ADT takeover on one of these, are the zones wired back individually on these? Or are they ID biscuits? Or zone expansion modules? i have 17 ccts on this one 2 keypads a bell I presume! Only 13 cables into the panel! Although there could be a few cables that have more than one device per cable, didn't want to open it up just in case it has tamper lock out.
