ABSTRACT:
An elevator system including at least one elevator car mounted in a building to serve the floors therein. The elevator car includes a door having one or more panels, and a door operator which selectively operates the door at the end of a run from the closed to a fully open position, or from the closed to a predetermined partially open position. Door control, in response to at least one predetermined parameter of the elevator system, controls the selection by the door operator. In a preferred embodiment, an audible message informs the passengers of the decision, at least when the doors will only be partially opened.
