A door apparatus for closing an access opening and to a parking apparatus equipped therewith. The door apparatus has two vertically aligned guide rails and an inner and an outer door element which are each movably mounted in/on a vertically aligned inner or outer guide of the guide rails. In a closed position, the inner door element is arranged in a first region of the access opening which is situated lower than a second region in which the outer door element is arranged. In an open position, the inner and the outer door element are arranged in a third region of the access opening which is situated higher than the first and the second region. Furthermore, the door apparatus has a locking element and a coupling element.

A movable barrier operator comprising a motor, communication circuitry configured to receive a control signal and communicate with a door lock associated with a passageway door, and a controller. The controller is configured to authenticate the control signal, wherein authenticating the control signal includes associating the signal with a first level of access or a second level of access. The controller is further configured to communicate with the door lock via the communication circuitry to permit opening of the passageway door in response to associating the control signal with the first level of access and inhibit opening of the passageway door in response to associating the control signal with the second level of access. The controller is configured to cause the motor to open the movable barrier regardless of association of the control signal with the first level of access or the second level of access.
