Abstract
In an elevator system utilizing up-peak channeling which displays the floors of the sectors to be served by each elevator during its next trip, visually handicapped persons alert the system by means of a signal transmission from a portable device, and are then enabled to enter a car call for any floor in the building. An embodiment with a lobby receiver enables calls to any floor in the next several elevators which may leave the lobby floor. An embodiment with receivers in every car enables calls to any floor in a car which receives the signal.
