I recently bought a house with a Vista 10SE W/E2 alarm system. The system has 1 6128 keypad located in the house. There is a "semi-detached" garage which has a motion detector. I want to add a 2nd keypad in the garage. I have a new 6128 mounted in the garage & connected & have run the wires into the alarm box inside the house. So far so good. I understand all I need to do is connect the new pad in parallel with the existing one, to terminals 4 (black) 5 (red) 6 (green) 7 (yellow). Seems simple, but I have 2 concerns1), the label in the alarm cover says "Remote keypads MUST be programmed with a #5137AD or 6139. It need not remain in the system... After programming, the system can use: (a bunch of keypads including the 6128 @30ma)." So do I need one of these other keypads (#5132AD or 6139) to program the new pad? Also 2) if all I need to do is connect the keypad to the correct screws, is the alarm company going to "freak" when I do this? Do I need to call them 1st (which I'd prefer not to do) or can I put the system in some "stand down" state while I connect the keypad, then re-activate it after?
