ABSTRACT:
A speaker system is provided adjacent to the gate of each of a plurality of elevator cars on each floor of a building. The speaker systems announce messages such as the car number of the next car in either direction, the estimated time of arrival of the car, that the car is full, the approximate delay for service by the next car to come, the car number and floor numbers being served by each loading elevator during up peak with channeling, the up calls are prohibited during up peak, the delay for service by the next car, and that all elevators should not be used in the case of fire or other emergency. Speaker systems are put on the doors of each stairwell on every floor, thereby to direct passengers toward the stairs in case of emergency. The system not only provides information and identification, it also provides audible, directional cues to assist the passengers in locating the service which they are to seek.
