An overhead door operator system (1) for opening and closing an opening (2), comprising a door frame (3) comprising a first frame section (4) at a first side (5) of the opening (2) and a second frame section (6) at a second side (7) of the opening (2). The operator system further comprises a door (8) arranged to be moved between an open and closed (C) position, the door (8) being movably connected to the door frame (3) and a drive unit (10) mounted on the door (8), the drive unit (10) comprising at least one motor (11) arranged to move the door (8) from the closed position (C) to the open position (O). An elongated transmission member (19) extends along the first side (5) of the opening (2) and the first frame section (4). The drive unit (10) further comprises a driven transmission member (18) in driving connection with the motor (11).

A movable barrier operator release mechanism includes an operator chassis having a first side. A shaft extending in a first direction from the first side of the chassis. A brake assembly coupled to the chassis and the first shaft extends into the brake assembly. The brake assembly includes a lever, mounted to a mounting plate of the brake assembly on end and freely movable at the other end. A cable attached to the lever that when pulled pivots the lever about its mounting point. When moved, the lever disengages the brake assembly allowing for free movement of the movable barrier.
