LRR issue trying to remove 7845gsm from Vista-20p

[ThompsonSR]

I have had the EnvisaLink 3 for a while now using in conjunction with a Vista-20p, 7845gsm and 8551 wireless receiver.
I have now gotten rid of my alarm monitoring service and I am having all kinds of fits trying to extract/disable/remove the 7845gsm from the mix.

Things I have tried:

• 1. Search the web high and low for how to deal with this issue - learned a lot about installing, not so much about uninstalling
  2. Unplugging A/C - v20p didn't like that at all...
  3. Changed *29 (LRR output) to 0 on the v20p - Stopped the errors, but I don't get any events from the envisalink
  4. Looked at *79 (Output Device Mapping) but all including 12(112) is set to 0 (delete)
  5. Disconnected A/C and wires to the v20p control panel - getting a "Fault 112 Relay Module" and sets off the siren every time I set the alarm, unless I manually bypass 112 first

Right now I am having to flip *29 to 0 to not have the wife hate me when she sets the alarm. So any help would be greatly appreciated.
