Taking a ride on the elevator in the parking garage at Harrah’s Resort Atlantic City. One interesting feature of these elevators that is not immediately apparent from the video is the presence of a “Door Hold” button in addition to the usual “Door Open” and “Door Close” buttons. These elevators have a very fast door cycle time – passengers have only a moment to enter and exit the elevator. Whereas the “Door Open” button keeps the doors open while continuous pressure is applied, pressing the “Door Hold” button momentarily provides at least 15 seconds of door dwell time, allowing passengers to unload their luggage without having to manually “hold” the doors by interrupting the photo sensor circuit.
