Issue
Second door reader (09 Door) does not work on 7920 controller
Environment
7920 DPU
Cause
If you have defined one door in a DPU-7920, and the door's exit reader parameter is set to anything besides NO, then the second reader port automatically becomes the exit reader.
Resolution
If you have defined two doors in a DPU 7920, neither door can have an exit reader defined. Set the door's exit reader parameter to NO.
