PART 2 - PRODUCTS

2.1 ROLLER SHADES

See Editing Instruction No. 1 in the Evaluations for cautions about naming manufacturers and products. Retain one of three paragraphs below. Retain list of manufacturers with either of first two paragraphs; insert list of manufacturers if retaining third paragraph. See Division 1 Section "Product Requirements."

A. Available Manufacturers: Provide products designed for this project by the following manufacturers:

1. Plastic-View ATC.

2. Solar-Screen.

3. Other manufacturer acceptable to the COTR.

Paragraphs and subparagraphs in this Article are examples only and are not intended to be all-inclusive for all products by all manufacturers. Retaining some options or combinations of options may result in a proprietary specification.

Retain first option in paragraph below if shade roller and operating hardware are exposed to view or concealed in a ceiling pocket; retain second option if needed for combination with fascia or headbox.

Retain first paragraph below if fascia alone or combined fascia and top/back cover headbox suit Project.

If standard headbox suits Project, retain two paragraphs above or paragraph below; either component can be combined with fascia end caps to form headbox. Delete all three paragraphs if a pocket with ceiling slot opening suits Project.

Retain first paragraph below if manufacturer's standard pocket for mounting a fully retractable shade flush and recessed above the ceiling, like mountings designed for overhead projection screens, suits Project.

2.2 ROLLER SHADE SYSTEM FABRICATION

A. Bottom Bar: Shades shall have a flat 1-inch by 1/2 inch, dull black, full width metal hemline bar, minimum of 26 gage, at bottom onto which the pull cord and shade are attached. Black plastic caps shall be provided on each end of hemline bar to cover any sharp exposed edges.

B. Shade Cords: Shade cords shall be black and of sufficient length to route around equipment to cord lock positions whenever required. The cords shall be 9/64 inch diameter rope made of 4.5 Duro Nylon and shall be attached underneath the center of the bottom of the hemline bar.

C. Shade Rollers: Shades shall be mounted on a 1-3/4 inch diameter corrosion resistant metal wrapped roller. The rollers shall be spring loaded, single piece barrel, with a reusable safety cotter key type retainer installed through both end pins and washers to prevent roller from falling out of mounting brackets. Constant tensions in shades is required.

D. Mounting Brackets: Provide mounting brackets with a 2-1/4 inch resting ledge. Standard ceiling brackets are not acceptable. A label stating "This End Down" with an arrow pointing in the proper installation direction of the roller into the mounting brackets shall be placed on the spring motor end of each shade roller. The shade film laminate material shall be mounted on rollers to minimize ridgings. Roll-off direction of material from roller shall be as directed by the shade manufacturer for use in the tower cab.

E. Each shade shall have a label or whatever suitable means required to specify and identify the proper roll-off direction.

F. Each shade shall have a manufacturer's label attached to the metal bar hemline giving cleaning instructions and the telephone number for emergency service.

G. Lock Pulley. Lock pulleys shall consist of a roller and a spring return side action cam cord grip.

H. Cord Direction Change Pulley: Provide cord direction change pulley which shall be used to route shade cord around obstructions where they exist. Pulleys shall be positioned in direct line with cord outlet on metal hemline.

I. Shade Size: Shade roller width shall be within 1/2-inch of maximum possible width as determined by physical limitations. Shade material with shade fully drawn shall be to within 1 inch of columns on bias (angle) cut sides and to within 1-3/4 inch of columns on vertical cut sides. Horizontal seam shall be located a minimum of 55 inches from the bottom of the shade. Shades in ATCT cabs shall be bias cut when required. To ensure a safe roll-up, a minimum of 15 inches of shade material shall remain on the roller when the shade is fully extended.

J. Measuring for Shades: Measuring for shades and positioning shall be strictly in accordance with the shade manufacturer's instructions. Marks showing the precise position of all brackets, pulleys, and metal hemline positions as related to the factory measuring instructions shall be provided. All measurements shall be taken per instructions from shade manufacturer.

2.3 MOTORIZED SHADE ROLLER

A. Tubular motor shall be contained within 1 3/4-inch shade roller. Motor shall be asynchronous, protected by automatic thermal cutoff, and 120 VAC/60HZ UL approved. Externally adjustable limits switches shall be provided to stop the shade at upper most and lower most shade positions. Use noise reduction roller brackets. Speed shall be 16-30 rpm.

PART 3 - EXECUTION

3.1 ROLLER SHADE INSTALLATION

Coordinate requirements for distance between roller shades and glass with clearances between shade perimeter and surrounding construction, glass type, and placement of heating/cooling air supplies to avoid heat buildup and possible damage to glass. Generally retain option for 2 inches (50 mm) in paragraph below. See Evaluations and GANA's "Glazing Manual."

A. Install roller shades level, plumb, and aligned with adjacent units according to manufacturer's written instructions. Allow clearances for window operation hardware.

B. Shades shall be installed in shade recess pockets or on wood or metal plates. Shades shall follow the slope of cab glass as closely as practical within physical limitations of air ducts and other equipment. No drilling shall be done in vertical uprights of cab because some uprights may contain electrical cables.

C. Spring tension in roller shall be manually adjusted so that shades roll comfortably and do not bind.

D. In order to safely control and limit the shade travel, the installer shall make two knots in the shade cord. One knot shall be placed before the lock pulley to prevent the metal hemline bar from hitting the windowsill. The second knot shall be placed after the lock pulley to prevent the metal hemline bar from hitting and overrunning the shade roller. Adherence to THIS END UP label when installing shade will prevent improper roller installation which can result in a locked shade situation when the metal bar hemline is near the lock pulley and cannot be pulled down to release the spring motor cam lock.

Delete first paragraph below if roller shades are manually operated only. See Evaluations for cautions about improper wiring.

E. Adjust and balance roller shades to operate smoothly, easily, safely, and free from binding or malfunction throughout entire operational range.

F. Clean roller shade surfaces after installation, according to manufacturer's written instructions.
