An automatic barrier operator system for operating a gate or upward acting garage door, for example, includes a controller for operating a reversible motor, a base radio frequency transmitter and a base radio frequency receiver. One or more remote control units include a radio frequency remote receiver and remote transmitter. The controller is operable to automatically close or open the barrier in response to a query signal sent from the base transmitter to the remote receiver and when the remote receiver is within range, returning a signal to effect operation of the barrier. The system is operable to effect operation or maintain the status quo of the barrier depending on the state of the barrier and a particular signal or lack of signal received by the controller from an authorized remote control unit or units. The system provides essentially hands-free automatic operation of opening and closing a garage door and the like.
A method for operating a barrier, such as a gate or garage door, to move between open and closed positions, said barrier being operably connected to an operator system including a controller comprising a base control circuit, a radio frequency base transmitter and a radio frequency base receiver and at least one remote control unit operable to communicate with said base control circuit, said remote control unit including a radio frequency remote transmitter and a radio frequency remote receiver, said method comprising the steps of:
