I am thinking of adding some keypads to my system. I have a 5010 with a wireless (433mHz) keypad. I have 17 zones listed on the door.
I would have liked to add 2 5500's but finding a used one at a "good price" might take some time.
Will an LCD5501z work just as well in my current setup? I do not know if there is a zone limit or what on these keypads. What is the difference in the two types (5501/5500)??
Is there going to be any sort of programming needed after the extra keypad is hooked up for either the 5501 or the 5500 ??
