Issue with Concord Installer Code and cell test

This is the issue I am having. Concord 4.
So far no luck on the Installer/Dealer code, but communication seems to be OK with ADC.
Will try Installer Code again this AM.

User codes I set on ADC work locally for arm/disarm. App iOS arms-disarms system too.
How can I check “System Master Code” — was that defaulted too?
That would be additional troubleshooting info as all TouchPads take “System Master Code” for owner changes IIRC?

It’s a recent Concord 4 system with takeover “private label TouchPads” (March 2017 install).
I wonder if all as-built pads might be the kind that do not allow Dealer/Installer programming? Ugh.
[i.e. original dealer uses ADC back-end toolbox and temp keypads at panel to do local programming, is that common?]

I probably need learn/master “technique” to pull TouchPads off the wall (without damaging anything) to check the OEM inetrlogix TouchPad model number too.

Good news system seems to fully work “as-built” by OE installer. Not 100% tested yet but shows “all ok”…Bad news I cannot add a Resolution 319.5 sensor in-hand, and a z-wave light controller yet… House going to be unoccupied for holidays and I really want an independent water check for the sump ASAP and temp check for HVAC !
