I have a concord express ADT monitored system that was installed by ADT. I was able to come by another control panel that I want to hook to the system. It is the same control panel as the orignally installed control panel. I hooked it up to the system in parallel and the second panel displays all of the system status correctly, but won't contol the system (such as arm, disarm). I am only able to control the system through the original control panel even though the second panel will display the systems state correctly. What is needed to be able to control the system from both panels?
Thanks
