I am having some difficulty understanding how to properly program a DSC Power 832 panel with 2 partitions sharing a common entry door. This is in a duplex with an outside door to a hallway. Each apartment has it's own entry door off of this common hallway. I have two LCD keypads (one for each unit) located in the hallway between the outside door and the interior apartment doors.
I have all 3 doors programmed as Delay 1 (Type 01) Zones. The outside door is assigned to both partitions. Each interior door is assigned only to its own partition.
When one partition is armed and the other is not, everything seems to work fine. The common outside door is not armed. If the interior door is opened before the corresponding partition is disarmed, the entry timer starts and the user can disarm the partition.
The problem I am having is when both partitions are armed. When I open the common outside door, it starts the entry timer on both partitions. Both partitions need to be disarmed to prevent an alarm from starting.
This is obviously NOT the way this system needs to work. Once the common door is opened, disarming either partition needs to disarm the common door.
What am I doing wrong, and how can I fix this?
