Hi there. We have recently moved into a home which has two Accenta key pads, one in the hallway and the other in the garage. I reset the code, date and time on the hallway keypad yesterday and then discovered the second keypad in the garage had also been reset with the same details. I initially thought that the two keypads operated independently of each other but this doesn't seem to be the case. Can I arm the garage without the whole house being armed? Do I need to part set the system every time? I have the instruction booklet (but no installer details) which identifies the various zones but am a bit confused about programs. Hope someone can help. Thank you in advance.
