Abstract
A plurality of hoistways (11, 12) in a building serving a plurality of floors utilizes destination call entry panels (22, 22A) having buttons (23) with which passengers can enter destination call requests. A display (26, 26a) adjacent the request buttons provides an indication of the car that is assigned to answer the passenger's request by a controller (27), which indication is also presented on illuminatable signs (16-19, 40, 41), utilizing either colors, letters or other easily identifiable and rememberable indications. As the car assigned to the call approaches the landing upon which the call was made, an illuminatable sign, adjacent the hoistway of the assigned car, will present the same color or indicia as was presented to the passenger upon entering the passenger's desired destination; the controller does not announce approaching cars that are not assigned a call at that landing.
