ABSTRACT:
An elevator system including an elevator car mounted for movement in a building to serve the floors therein, and a call entry and display station for registering calls for destination floors. The call entry panel includes a plurality of switches, and notations which identify the floor each switch is associated with. A selector sequentially addresses the switches responsive to addresses provided by a programmed memory. The memory is programmed at the factory according to the desired notational sequence applied to the switches, which enables the physical arrangement of the switches and the wiring thereof to be standardized. New and improved apparatus for monitoring a plurality of switches, is also disclosed.
