ABSTRACT:
An elevator system for controlling an elevator car includes an elevator control having an input/output port and means for latching the port at a voltage level when a signal is coupled thereto. A single wire connects the elevator control to each of a plurality of call registration means which are disposed remotely from the elevator control, with the call registration means actuable to request elevator service. Each single wire also connects call acknowledgement means to the elevator control, with the call acknowledgement means actuable by the control to acknowledge a request for elevator service. Actuation of the call registartion means causes a signal to be coupled over the single wire to the input/output port, in turn causing the port to be latched at the voltage level. This voltage is connected by the single wire to the acknowledgement means to actuate same and thereby acknowledge a request for elevator service.
