ABSTRACT:
A signal transfer system for an elevator including a master station and a plurality of slave stations, each slave station having provision for generating call signals and illuminating a call registratioin lamp. The master station generates a call registration signal in response to cage call and hall call signals. Each slave station also includes a timer which measures the time interval between transmission of a hall or cage call signal and a call registration signal. When the call registration signal is not received within a predetermined period of time, the respective slave station retransmits the hall or cage call signal. The call registration lamp is extinguished if the slave station has not received the call registration signal after a predetermined number of signal retransmissions.
