At the proper point in the car travel, the operator in the car is notified by a signal (visual, audible, or otherwise) to initiate the stop, after which the landing stop is automatic.
(G) Signal Operation. Operation by means of single buttons or switches, or both, in the car, and up-or-down direction buttons, or both, at the landings, by which predetermined landing stops may be set up or registered for an elevator or for a group of elevators. The stops set up by momentary actuation of the car buttons are made automatically in succession as the car reaches those landings, irrespective of its direction of travel or the sequence in which the buttons are actuated. The stops set up by the momentary actuation of the up-and-down buttons at the landing are made automatically by the first available car in the group approaching the landing in the corresponding direction, irrespective of the sequence in which the buttons are actuated.
