Abstract: A coded signaling and control system including one or more transmitters and one or more receivers, wherein both the transmitters and the receivers are coded or programmed to transmit a unique signal for actuating only selected ones of the receivers. Digital logic and switching circuits are used to generate a transmission sequence containing an initial reset burst followed by alternate shift and code bit signals terminating with a comparison and latching signal. All of the receivers in the system receive the initial reset signal and the alternate shift and data bit sequence; however, only the selected receiver programmed for the precise code being transmitted will generate a true comparison signal. Thereafter, all of the other receivers will be reset and the desired receiver will be sequenced to respond to an "off" or "on" latching signal for providing any desired output function, such as operating an alarm, controlling an associated piece of equipment, and the like.
