732.02<br />

includes LED lamp in accordance with 732.04. Twelve-inch (300 mm) lenses are<br />

the st<strong>and</strong>ard wide angle type. All hardware used to join optical sections together<br />

shall be stainless steel.<br />

Fit each optical section with a cutaway type visor unless other type visors or<br />

louvering is specified. Ensure that the visors for 8-inch (200 mm) lenses are at<br />

least 7 inches (175 mm) long <strong>and</strong> those for 12-inch (300 mm) lenses are at least 9<br />

1/2 inches (240 mm) long.<br />

Ensure that optical sections are designed for assembly with all 8-inch (200 mm),<br />

all 12-inch (300 mm), or intermixed arrangements. Assemble using suitable<br />

hardware that forms weatherpro<strong>of</strong> joints with no light leakage from one section to<br />

another. Ensure that the assembly arrangements contain the specified number <strong>of</strong><br />

optical sections, lens size, lens color, <strong>and</strong> circular or arrow configuration.<br />

Assemble from one to a maximum <strong>of</strong> five sections as specified to form a signal<br />

face.<br />

Furnish multi-way heads with appropriate top <strong>and</strong> bottom brackets with an<br />

opening in the center <strong>of</strong> the top bracket provided for mounting purposes. Correct<br />

signal face height inequalities for multi-way heads for proper accommodation<br />

between top <strong>and</strong> bottom brackets by the use <strong>of</strong> pipe spacers.<br />

Furnish signal heads with required mounting hardware. Furnish signal face<br />

orientation to traffic by serrated rings or other devices on housing sections <strong>and</strong><br />

mounting hardware. Permit adjustment in increments not greater than 5 degrees <strong>of</strong><br />

rotation <strong>and</strong> not affected by wind gusts when locked. Furnish galvanized steel or<br />

aluminum spacers <strong>and</strong> drop pipes 1 1/2 inches (38 mm) nominal pipe size (1.90<br />

inch (48 mm) actual diameter). Ensure that disconnect hangers have at least<br />

twelve terminals unless a greater number is required.<br />

Paint signal external surfaces with yellow enamel paint, Color 13655, Federal<br />

St<strong>and</strong>ard 595 or gloss black to closely agree with Federal St<strong>and</strong>ard 595, Color<br />

13655 or Color 17038, as specified in the plans. Paint interior surfaces <strong>of</strong> visors<br />

flat black.<br />

Furnish materials according to the <strong>Department</strong>’s Qualified Products List (QPL).<br />

732.02 Vehicular Signal Heads, Optically Programmed, 12-inch (300 mm)<br />

Lens. Ensure that optically programmed signal heads incorporate an optical<br />

system projecting an indication that is programmed to be visible only within<br />

boundaries <strong>of</strong> a specific area. Ensure that the optical system is capable <strong>of</strong> being<br />

veiled anywhere to within 15 degrees <strong>of</strong> the optical axis using procedures <strong>and</strong><br />

opaquing material according to the manufacturer’s instructions.<br />

Ensure that the signal sections conform to applicable portions <strong>of</strong> the ITE<br />

st<strong>and</strong>ard <strong>and</strong> 732.01. Furnish <strong>and</strong> mount optical sections with a 12-inch (300 mm)<br />

lens size alone or in combination with additional sections <strong>of</strong> optically programmed<br />

or conventional optics types to form signal faces <strong>and</strong> heads. Furnish an optically<br />

programmed signal section that includes an inc<strong>and</strong>escent lamp or, if specified, a<br />

LED lamp.<br />

Balance adjusters, if specified, shall have a splined eyebolt design <strong>and</strong> splined<br />

external clamping body. All assembly hardware shall be stainless steel.<br />
