Installing the Vista Ademco/Honeywell 20P works with the alpha keypad addressed to (16) I programmed The standard lcd keypad upstairs (1 & 3 at the same time) to 17. Looks like 17 is programmed as a second keypad in the Program by default (checked and confirmed) . Everytime I connect the second keypad the alarm does not work. Any help appreciated. Dave
