Existing ADT DSC Impassa want to integrate with ST

Hi everyone.

I’m new here. Coming over from a control4 EA-3 system because it cost to much money to integrate everything I need, plus you have to pay for the dealers time for every integration.

I want to do it my self. that’s what brought me to ST.

I have an existing ADT DSC impasse panel with ADT service. What do I need to do in order to tie into ST? Can I go through ADT for whatever I need? If I get the panel from say Best buy - can I get ADT to install it?

How does this work?
