What do I need?

Hi, I have a DSC board using 7 zones in my house. I really don’t care to monitor the status of each zone. All I want to be able to do is arm and disarm my alarm in stay and away mode remotely and to be able to get alerts when the alarm has been triggered. Can someone please guide me as to the minimal konnectrd hardware I need to be able to interface with my EXISTING alarm. I want to keep my DSC alarm in place and again don’t care to monitor the individual zones.
