I'm hoping someone here might have some expertise with this issue. I recently bought a house with a pre-installed ADT alarm system. System was installed in 2000. User manual says it is either a VIA-30PSE or a Vista-10SE. I believe it is the latter. It has a single 6127/6128 keypad in the house. The semi-detached garage has a motion detector. I would like to add another keypad to the garage, since getting into/out of the car/pulling in/pulling out/opening/shutting the garage door before the entry/exit delay is proving to be a bit of a push. . Right now, I have that zone bypassed, but this is a pain, not only because I WANT protection out there, but also because (apparently) you have to BYPASS the zone EACH TIME re-activate the system. I've run all kinds of wiring & am not concerned with the technical aspects of installing the keypad, but I'm wondering what keypad to get. 6128 keypads are available used on Ebay, new ones are surprisingly expensive. Also, all I have is the fairly useless from a technical standpoint user manual. Is there any technical info online, as to how & where to connect a
2nd pad to the system?Thanks
