The disclosure relates to a method at a control device (100) for controlling an overhead door operator system, the overhead door operator system (1) being configured for opening and closing an opening (2), and comprising a door frame (3) comprising a first frame section (4) at a first side (7) of the opening (2) and a second frame section (6) at a second side (5) 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 (7) 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). The method comprises the steps of: detecting door movement; determining if detected door movement relates to unexpected door movement; and, if so, taking action so as to prevent more extensive damages. The disclosure further relates to an overhead door operator system for opening and closing an opening.

An automated window mechanism is disclosed having an electric motor attached to a sliding panel of a window configured to open and close the window by moving the sliding panel. The electric motor has a locked state in which the electric motor and sliding panel are stationary. The automated window mechanism also includes a monitor configured to detect an external force applied to the sliding panel while the electric motor is in the locked state. In response to the monitor identifying the external force while the electric motor is in the locked state the electric motor opposes the external force to prevent unwanted movement of the sliding panel. A method and system for preventing unwanted movement of an automated window are also disclosed.

A fire door operator for a rolling door includes a housing defining an axis. An outer main gear in the form of an annular ring is mounted within the housing for rotation about the axis and formed with exterior gear teeth and radially inwardly spaced interior teeth. Planet gears are meshed with the interior teeth and a sun gear is meshed with the planet gears for rotation about the axis. A carrier is secured to the planetary gears and coupled to the shaft. A lock normally locks the main gear in relation to the housing. A drive selectively rotates the sun gear and the carrier to transmit rotational power to a rolling door shaft when secured to the carrier. A releasing device selectively releases the lock to allow free rotation of the main gear and the carrier to allow a rolling door to be lowered under its own weight.

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.

In accordance with one aspect of the present disclosure, a head unit of a movable barrier operator is provided including a motor for moving a movable barrier and a first circuit board operable to provide power to the motor. The head unit includes a fire-resistant container that contains the first circuit board. This permits the electrical components of the head unit that utilize higher voltage, such as 120 volts, to be provided on the first circuit board and contained in the fire-resistant container. The head unit further includes a second circuit board outside of the fire-resistant container and operably coupled to the first circuit board. Because the second circuit board is outside of the fire-resistant container, the second circuit board may contain electrical components of the head unit that operate at lower voltages, such as at or below 24 volts.
