Hi can anyone tell me if its possible to have 2 entry and exit zones for the Accenta G4, i have a remote keypad behind my front door and one behind my electric garage door, is it possible that i could set and unset the alarm from either keypad and leave the house by that exit, or can there only be one final exit door. i was planning on putting a roller shutter doot contact on the garage and a magentic contact on the front door but unsure of how to set it up.
