[KBA-01447] False "Door forced open" event is generated when a door is configured to not unlock on REX
This article explains why a door configured as Card-In/REX out with Automatically grant REX set to Off, still generates a Door Forced Open event when the door is opened after triggering a REX.
When a door configured as Card-In/REX out with Automatically grant REX set to Off is managed by an HID controller, triggering the REX and then manually opening the door generates a Door Forced Open event.
When the Automatically grant REX setting for a door is set to Off, a coding issue results in a REX grant time of 0 seconds.
This issue is resolved in Security Center 5.4 SR3.
