not familiar with a vista 12D
but each zone should be programed as something,
(01-door,02-door, 03-permeter, 04-motion,etc...)
If there is still 00 in that slot then it will not report..
Then there should be a reporting code,
(01 - 0E)
this site has the full programming manual if you don't
have a copy...
