The invention relates to an overhead door for covering a door opening comprising a door blade (11) with a plurality of panels (17), said door blade (11) being movable between a vertical, closed position and a horizontal, opened or overhead position within a side frame (12) comprising double-sided a vertical track (13) and a horizontal track (14), connected by a connecting portion (15), respectively, and with a belt (20) or a chain associated with one side each of the said side frame (12) to lift the panels (17) from said vertical position to said horizontal position. To develop the stated overhead door in a way that the advantages of a high speed rollup door and an overhead door are combined, to offer an overhead door with a low space requirement, low maintenance requirements and a high speed closing possibility, the stated overhead door comprises driving means (27) for simultaneously driving a plurality of said panels (17).

A closure system for door openings defined in a wall (P) and comprising: a quick-opening door (1) adjustedly installed within the door opening (H) and featuring a flexible roll-up sheet (11), an upper casing (12), and vertical uprights (3) equipped with guides (31) for the displacement of the flexible sheet (11); a fire door (2) installed at one side of the wall and comprising at least one fireproof layer (21, 23), for the opening and closure of the door opening (H), a perimeter frame constituted by the vertical uprights (3) and a rearward fireproof cover (4) of the upper casing (12) of the quick-opening door (1).

A dual-voltage door operator control system comprises a contactor, a high-voltage connector, a low-voltage connector, a rectifier and a brake. When a door operator motor is electrically coupled to the low-voltage connector, the rectifier full-wave rectifies an external power source and then electrically energizes the brake. When the door operator motor is electrically coupled to the high-voltage connector, the rectifier half-wave rectifies the external power source and then electrically energizes the brake. Accordingly, the door operator motor can be connected to the high-voltage connector or the low-voltage connector according to the specification of the external power source provided at the site. Moreover, the invention is also further integrated with the brake of a single specification, and no matter whether the external power source is a high-voltage power source or a low-voltage power source, it can electrically energize the brake through the rectifier.
