Abstract
A remote control system including a central encoder for transmitting a single sequence of control pulses to a plurality of remote decoders, each of which performs a predetermined function when it has received a selected number of pulses. Reliability of the system is enhanced by including in the encoder and all of the decoders a number of electromechanical relays arranged in a special triple redundant configuration, such that no failure in any one relay can cause a decoder to perform its function at an undesired time or can prevent a decoder from properly performing its function at a desired time. In addition, the special use of supplemental relay contacts ensures that no failure of any solid state device in the encoder or decoders can cause a decoder to perform its function at an undesired time.
