Provide all warranty documentation as specified in Section 950.3(j) to the Representative at final acceptance.
System must conform to 47 CFR 15. Provide LED Blank -Out Signs according to Publication 236; MUTCD; the current ITE Standard for “Vehicle Traffic Control Signal Heads - Light Emitting Diode (LED) Circular Signal Supplement.” Sign display message symbols and characters must be according to Publication 236 and the MUTCD. Provide sign assembly capable of working in coordination with signal controller, flashing beacons, or illuminated messages as indicated. Sign assembly includes the appropriate equipment and cabling to allow communications, photoelectric cells, and mounting hardware. Include all hardware to provide a functional assembly capable of operating under all weather conditions. When applicable, the assembly will include internally illuminated messages in an opaque housing with a face of translucent plastic. Signs will be capable of maintaining illuminated LED message if power failure occurs. LED message must not be visible when extinguished. LED message should be dimmable to adjust to ambient light conditions and vehicle headlights to ensure legibility from at least 400 feet. Provide sign assembly capable of obtaining power from traffic signal cabinet . Provide successful laboratory test results verification from manufacturer. Provide all warranty documentation as specified in Section 950.3(j) to the Representative at final acceptance.
System must conform to 47 CFR 15. Utilize approved LEDs , ensuring that all LEDs are operable from a solar or electrical self -contained source capable of supplying power to the device. LEDs modules are to be placed around the perimeter outer edge of the sign. The LED modules cannot be placed within the background area of the sign except for “Stop” and “Yield” signs where LEDs may be placed within one border distance within the background of the sign. Border distance dimensions must be according to Publication 236. The LEDs are to be wired so that all other LEDs will continue to operate if one were to fail. If LEDs are flashed, all LEDs must flash simultaneously and have a flash rate of more than 50 and less than 60 times per minute. LEDs must match the following colors based on the sign type.
• White or red if used with “Stop” , “Yield”, “Do not enter” , and “Wrong Way” signs.
• White if used with other regulatory signs.
• White or yellow if used with warning signs and school area signs.
• White if used with guide signs.
• White, Yellow , or O range if used with temporary traffic control signs.
All LEDs used on an individual sign must be of the same production batch for uniformity. Chr
