All of my rooms are controlled this way. I've found that when an adjacent room had a sensor (all of mine do) the system will look for a trip in that room after a non trip in adjacent room. For example let's say living room only had one way into another room and it's through the kitchenWhen living room is NOT tripped, wait 3 seconds for Kitchen to trip. If it didn't trip then someone is still in the Living roomI hope that concept helps.
