Abstract:
1. A barrier operator system adapted to receive different wireless frequency signals from different frequency transmitters so as to move a barrier between limit positions, the system comprising: a primary controller which initiates and controls movement of a single barrier; a first receiver circuit directly receiving only a first wireless frequency signal from a first transmitter from which said first wireless frequency signal originates and electrically connected to said primary controller; and a second receiver circuit directly receiving only a second wireless frequency signal from a second transmitter from which said second wireless frequency signal originates and electrically connected to said primary controller, wherein both said receiver circuits and said primary controller are maintained within an operator mechanism, and wherein said first wireless frequency signal is different than said second wireless frequency signal, and wherein said primary controller validates said first and second wireless frequency signals and subsequently initiates over a wired secure connection an operational function of said operator mechanism including moving said barrier.
