1. Solar Absorptions: 61 percent.

2. Shading Coefficient: 0.45.

3. Solar Heat Gain Coefficient: 0.40.

2.3 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. Bar will have a minimum of three (3) rollers designed to prevent scratching the window glass. 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 minimum 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 tension in shades is required. The shade roller shall have brushes that remove dust form the shade as it is rolled up, but does not hinder the roll down operation.

D. Motorized Shade Roller

1. Tubular motor shall be contained within 2-inch shade roller. Motors shall be asynchronous, protected by automatic thermal cutoff and 120 VAC/60 HZ UL approved.

Externally adjustable limit switches shall be provided to stop the shade at uppermost and lowermost shade position. Use noise reduction roller brackets. Speed shall be 16-30 rpm.

2. Shades shall be individually switched for each unit. A master control unit and individual control units shall be located in accordance with requirements specified in individual task orders. Hand cranks shall be provided for operation in the event of power or motor failure.

E. 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 ridging. Roll-off direction of material from roller shall be as directed by the shade manufacturer for use in the tower cab.

F. Each shade shall have a label or other approved suitable means that specifies and identifies the proper roll-off direction.

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

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

I. 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.

FA3099-18-Q-0024, RSU Plastic View Shade

J. Shade Size: Shade roller width shall be within 1/2-inch of maximum possible width as determined by physical limitations. Shade material width with shade fully drawn shall be to within 1 inch of columns on bias 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.

K. Measuring for Shades: Measuring and positioning for shades shall be performed 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.

PART 3 - EXECUTION

3.1 COORDINATION

A. Individual task orders will include site-specific requirements for each project. These requirements will include, but not be limited to:

1. Allowable working hours

2. Project coordination requirements

3. Project schedule that includes a schedule for deliverables.

4. Pre-installation site visit(s) to field verify all measurements prior to fabrication

3.2 INSTALLATION

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

DOWN” 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.

E. For motorized shades, check limit switches for control and shade travel. Test controls at each console for operations. Prevent improper roller installation by strict adherence to the “THIS

END DOWN” label when installing shade.

F. Shades shall be able to operate at a moment’s notice; to gain unimpeded rapid access for the use of emergency light guns. The inability for one controller to “snap-up” the shade in an

FA3099-18-Q-0024, RSU Plastic View Shade emergency endangers lives, and system that does not meet the unimpeded rapid access will not be approved.

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

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