ABSTRACT:
A system for moving a barrier between limit positions, includes an operator motor assembly mounted proximate to the barrier, wherein at least a portion of the motor assembly is movable between an operating position and a locking position with the motor assembly blocking movement of the barrier. A bias assembly biases the motor assembly in the operating position and allows the motor assembly to move toward the locking position when either a predetermined force overcomes a biasing force or when the barrier is moved to a closed limit position or when forced entry is imposed on the barrier. The biasing force may be adjusted by moving posts on the motor assembly that are engaged by the bias assembly. A disengagement feature may also be provided that allows pivotable movement of the motor assembly even when in a locking position. And the pivoting motor assembly may be used as a secondary entrapment input to an operator controller.
