General Overview
When a person badges into door but does not open it, we can use global linkages to set the door unlocked. If someone then scans their badge on the unlocked door it resets its state.
The reason we do this in the because it prevents the teachers from leaving their doors open. When the "secure mode" button is pressed it resets all the door states. Arming the alarm also resets their state.
Door Status
The color of the light on the reader indicates if the door is locked or not. Red - Locked, Green - Unlocked
This is set on a per-door basis.
