1. In a barrier operator system for moving a barrier between open and closed positions, a motor operably connected to drive said barrier, a base controller operably connected to said motor and operable to receive signals from barrier position limit detection means, and at least one remote control unit operable for wireless communication with said base controller, the improvement characterized by:

  • said base controller including an RF base transceiver and said at least one remote control unit includes an RF remote transceiver for communicating with said base transceiver, said remote control unit including status indicator means operable to indicate the status of said barrier as being one of open, opening, closed, closing, and obstruction detected in response to receiving signals from said base transceiver by way of said remote transceiver;

    an obstruction detector including a detector transceiver for communicating obstruction detection signals to at least one of said base transceiver and said remote transceiver; and

    a power controller switching said obstruction detector between a power consumption mode and a low power consumption mode;

    wherein said detector transceiver receives wireless control signals and activates said power controller upon receipt of said wireless control signals.
