Abstract
A barrier operator system is provided including a controller, a motor, a barrier, a power source, and a remote transmitter. The controller scans for a reduced range of radio frequencies while operating in a standby mode to conserve energy. In response to receiving a signal from the remote transmitter, the barrier operator will exit the standby mode and scan for a broader range of frequencies. In response to receiving a command signal from the remote transmitter, the controller will operate the barrier. The controller also scans for signals from an accessory device after exiting the standby mode. The accessory device may also operate in multiple modes with respect to scanning for transmissions and sending signals to the controller.
