Abstract: In one aspect, a movable barrier operator system is provided that includes a motor configured to be coupled to a movable barrier. The motor has a power rating indicative of a minimum power to be supplied to the motor in order for the motor to move the movable barrier. The system further includes an external power supply configured to connect to an electrical outlet. The external power supply has a plurality of outputs each having a power rating indicative of a maximum power the output supplies, the output power rating being less than the motor power rating. The movable barrier operator system includes combiner circuitry configured to combine power from the outputs of the external power supply and provide the combined power to the motor. The system further includes a monitoring circuit configured to detect a fault condition of any of the outputs of the external power supply.

Abstract: A movable barrier operator comprising a motor, communication circuitry configured to receive a control signal and communicate with a door lock associated with a passageway door, and a controller. The controller is configured to authenticate the control signal, wherein authenticating the control signal includes associating the signal with a first level of access or a second level of access. The controller is further configured to communicate with the door lock via the communication circuitry to permit opening of the passageway door in response to associating the control signal with the first level of access and inhibit opening of the passageway door in response to associating the control signal with the second level of access. The controller is configured to cause the motor to open the movable barrier regardless of association of the control signal with the first level of access or the second level of access.
