Common Doors can be designated in order to duplicate access given on another door to the common door.
Similar to Door Groups, where a group of locks can allow you to assign access to a user and to all locks within a group with just a few clicks. A common door will allow you to associate one door with other common doors at the same location.
For example, if a building has 10 locks on interior units and one exterior front door, the front door can be made common to all the locks on that Location. This way, when any Access User is added to an interior door, the user will be duplicated on the Front Door (the Common Door).
This system operates on a Master/slave model of communication where one device has unidirectional control over one or more other devices. Please see the screenshot below as a visual.
How to add common door functionality:
