I plan on getting a Vista 20P, and expand the zone quantity via a 4219 module.
My questions is this: Does this bring the total number of zones to 16, or 15? I'm concerned, because the 20p manual states:
"For zones 09-16, set module to Device Address 07".
Does "Address 07" = "zone 07", or is this separate? I'm guessing that it's referring to device addresses like in keypads.... since the expander module connects to the keypad terminals to begin with, right?
I need to have 16 zones. If I am stuck with 15 zones, I'm up the creek on this one Thank you!
