Provide a bottom beam of a suitable width and depth to carry the load of the intermediate beams when the door is not closed, and to ensure full closing and a tight floor seal under full design wind speeds spanning between windlocks located at each jamb.

Provide a heavy-duty bottom rubber seal to form a tight seal with the floor under all design conditions. Provide a bottom edge safety device that is integral with the bottom seal.

Design bottom beams to span between safety arrestors at the jambs and support the weight of the door, including intermediate beams, while remaining stable and within the door guides. If the door leaf safety arrestor alternative is utilized per paragraph DOOR LEAF SAFETY ARRESTERS, design the bottom beam to support the weight of the door, including intermediate beams with either end belt/wire rope, or any two intermediate belts/wire ropes, removed while remaining stable and within the door guides. Midspan splices are prohibited in the bottom beam.

2.6 WIND LOCK

At each door leaf provide wind locks at each jamb, which automatically activate and lock the bottom beam into place when the door reaches its closed position to maintain a tight floor seal and intermediate beam stability with tight fabric under design wind conditions. Provide a limit switch, or a proximity switch, with indicator to notify the door operator

SECTION 08 34 16.20 Page 15 that all wind locks are engaged properly. Provide switches located below 18 inches above finish floor that are compliant with NFPA 70 , Class I, Division 2 hazardous environment.

[] 2.7 OPERATION

2.7.1 Door Operation

Provide a vertical lift fabric door which guides up and down in weather sealed vertical guides attached to the structure[ and mullions]. Provide a door system which operates by lifting the bottom beam upwards in each door leaf, thereby stacking the intermediate beams one on top of the other, with the fabric material folding in pleats. Door operational safety is of paramount importance.

When the door system is fully open, all door system components will be outside of the required clearance area for the door opening.

When the door system is fully closed the door system will seal the opening and form a portion of the building's air barrier. The intermediate beams hang between the two fabric faces thus pulling the fabric material tight and sealing along the guides at each jamb. The tension created in the fabric panels is permitted to stabilize the intermediate beams, if proven capable by the manufacturer, and the bottom beam seal will fit tightly along the entire length of the door threshold.

Submit in accordance with Section 01 78 23 OPERATION AND MAINTENANCE DATA. Including wiring diagrams and the complete manufacturer's instructions for operation and maintenance of the doors, door mullions where indicated, and accessories, including emergency operation, in the event of general building power failure to the doors.

2.7.2 Electrical Operation

Provide the main control panel with control logic such that when the integral female pin and sleeve emergency power receptacle is inserted and the integral manual transfer switch associated with the pin and sleeve receptacle is engaged the control panel will automatically limit only one door lift motor or one mullion lift motor to operate at a time.

The door will be stopped by a primary limit switch when the door is opened completely. In case of over travel, the door will be stopped by a secondary limit switch to prevent damage. Slack belt/wire rope breakers will stop the drive unit when the door is closed. In case of belt/wire rope break/rupture or if an obstruction should prevent the door from being closed the slack belt/wire rope breakers will also stop the drive unit.

Weight or springs activate the slack breakers.

Control door operation by three buttons marked "OPEN", "CLOSE", and "STOP". The "OPEN" and "STOP" buttons require only momentary pressure to operate. The "CLOSE" button requires constant pressure to maintain the closing motion of the door. The door will immediately stop, and remain in that position, when the door is in motion and the "STOP" button is pressed or the "CLOSE" button is released. From that stop position, the door operation is then continued in either direction by the "OPEN" or "CLOSE" buttons. Removing the pressure from the "CLOSE" button results in stopping the motor drive and setting the brake.

2.8 FINISHES

2.8.1 Aluminum

Clear Anodized: Conforming to AA-M12-C22-A41 in accordance with NAAMM AMP 500 and complying with AAMA 611. The minimum finish thickness is

0.7 mil or greater.

2.9 SIGNAGE

Provide a placard sign immediately adjacent to all control panels indicating the below Notice. Include the service level wind speed which corresponds to the ultimate wind speed used in design of the open/operational door in paragraph WIND LOADS in the Notice post..

Notice:

Vertical lift fabric doors will be closed and not operated when wind speeds above[ 60 mph ][_____] are expected.

Vertical lift fabric doors will be transferred to back-up power for operation when commercial power is not available.

PART 3 EXECUTION

3.1 PROTECTIVE COATINGS

3.1.1 Cleaning

After fabrication, clean all metal surfaces thoroughly of all mill scale, rust, oil, grease and other foreign substances. Apply rust-preventive primer to all steel parts immediately after cleaning.

3.1.2 Shop Painting

After cleaning, coat with primer all steel surfaces other than machine-finished parts. Keep paint off finished bearing surfaces. Before assembly, prime surfaces that will be inaccessible after assembly. Handle painted materials with care to avoid scraping and breaking the protective film. Ferrous metal surfaces that will be exposed after fabrication will be shop coated and touch-up painted in the field in accordance with the paragraph FINISHES.

3.1.3 Metal Protection

Provide in accordance with Chapter 4 of UFC 1-200-01 when door system is in a corrosion prone location or where door system components use dissimilar metals. If dissimilar metals are used, also provide in accordance with MIL-STD-889 . Provide added corrosion protection to the design such as, but not limited to, the following. Where aluminum will contact dissimilar metals, protect against galvanic action by painting contact surfaces with primer or by applying sealant or tape recommended by manufacturer for this purpose. Where aluminum will contact masonry or concrete, protect against corrosion by painting contact surfaces with bituminous coating.
