PART 2 PRODUCTS

MATERIALS

• A. Curtain shall be assembled from interlocking Type 3 (2 1/2″ x 3/4″) flat slats, roll-formed from 22 gauge minimum galvanized steel [22 gauge minimum stainless steel] [.050” aluminum] strip. [Type 33 (2 1/2″ x 7/8”) flat slats shall be insulated with expanded polystyrene (EPS) foam and covered with fully interlocking backseats roll-formed from material matching the slats.] Malleable iron end locks, or windsocks as required by wind load design, shall be riveted to ends of alternate slats. Delrin end blocks shall be riveted to the ends of every 4th slat on doors without windsocks to reduce friction. The curtain shall be provided with the Scratch-Guards Protection System – 2” wide elasticized black straps secured to the coil side and spaced approximately every 3’ across the curtain – to reduce finish wear and operating noise.
• B. Bottom bar shall be a rectangular aluminum extrusion, 4 5/8” high x 1 3/4” wide, attached to the bottom of the curtain to limit vertical and lateral deflection. The bottom bar shall be self-leveling to accommodate slopes up to 1/2”.
• C. Guides shall be 3/16” steel U-channels fitted with replaceable extruded UHMW wear strips, bolted to 1/4” minimum steel wall angles, with integrated mounting for the light curtain. Guides shall be assembled with 3/8” minimum bolts no more than 24” on the center and attached to the wall with 1/2” minimum bolts no more than 24” in the center. Removable curtain stops shall be provided.
• D. Barrel shall be steel pipe, 8 5/8” minimum diameter. Pipe shall be sized to minimize operating revolutions and support curtain with a maximum deflection of 0.03” per ft. of width. Steel shafts, 1 1/2” minimum diameter, shall be used to support each end of the barrel.
• E. Brackets shall be 1/4” minimum steel plates bolted to wall tubes. Plates shall be sized to support the curtain and barrel and provided with flanges for hood attachment. Brackets shall be fitted with self-aligning 4-bolt iron flange bearings.
• F. Hood shall be formed from 24 gauge minimum galvanized steel [24 gauge stainless steel] [.040” aluminum] sheet with top and bottom reinforcements to reduce deflection. [Brush weather seal shall be field installed on the header.]
• G. Operation of doors shall be by a Model HGH inline gear drive motor operator, UL Listed, 2 HP minimum, 208/230/460v-3ph, continuous duty motor, auxiliary chain hoist, integral speed governor to prevent curtain free-fall in event of operator component failure, adjustable soft start/stop variable speed controller, solenoid-actuated brake, adjustable limit switches, delay on reverse, non-resettable cycle counter, adjustable reclose timer, and auxiliary transformer to support secondary sensors and ancillary control devices. The drive chain shall be a minimum #80 roller chain. The motor operator shall be mounted horizontally in front of and parallel to the door coil and shall not require additional clearance above the top of the coil. The control panel shall be mounted on the wall and connected to the motor operator via pre-assembled wiring harnesses. Average operating speeds shall be approximately 24” per second to open, 12” per second to close, and shall slow substantially before full open and full close.
• H. Sensing devices shall be provided to stop and reverse the door when closing if an obstruction in the opening is detected. A wireless monitored sensing edge, consisting of a rubber dual-chamber profile with integral isolated conductive elastomer switches, shall be attached to the bottom of the bottom bar to stop and reverse the door upon contact with an obstruction. Upon monitoring a sensing edge system fault condition, the door will stay in or return to the open position and revert to a constant pressure close function to allow partial operability until the fault is corrected. A monitored light curtain shall also be provided to stop and reverse the door upon sensing an obstruction in the opening. [Loop detectors shall be installed to stop and reverse a closing door upon sensing the presence of a vehicle.]
• I. Locking shall be provided by self-locking gear reduction of the motor operator.

FINISHES

• A. Galvanized steel slats [backslats] and hood shall have a baked-on primer and grey polyester top coat. [Stainless steel slats and hood shall have a brush finish.] [Aluminum slats and hood shall have a clear anodized finish.] The aluminum bottom bar shall be clear anodized. Steel guides and brackets shall be shop-painted with a black color rust-inhibiting primer.
