1. BACKGROUND:

This requirement is to procure and deliver crosswalk equipment for the 92 Civil Engineer Squadron at Fairchild AFB. Contractor will provide all equipment and delivery to provide Fairchild AFB with the equipment listed below.

Provide multiple levels of blinker sign LED brightness through LED drive current control If specified, automatically adjust the blinker sign LED drive current control to optimize brightness for the ambient lighting conditions, automatically adjust the blinker sign LED duty cycle to save battery during nighttime operation.

The blinker sign LED drive outputs reach the full output current as programmed within the duration of the 100ms on-time.

Include an integrated Real Time Clock (RTC) with on-board battery backup.

Have the capability of RS232 communication for programming with Windows-based software.

Shall operate on the license-free ISM band, comply with part 15 of FCC rules, operate from 3.3VDC to 15VDC, be replaceable independently of other components.

3.4 Solar Panel

65W Solar panels or larger Solar Panel shall be constructed of an anodized aluminum frame, high-transmission 1/8" tempered glass, with silicon cells encapsulated in double-layer EVA, and with a white polymer backing.

The Solar Panel shall be able to be affixed to a pole top bracket that allows an adjustable angle to provide maximum insolation exposure

To ensure maximum solar insolation regardless of installation location, the post top mounting system shall provide 360° of rotational direction adjustment and upon installation, must be oriented with the collector facing South.

The solar panel must be IEC61215 and TUV certified. The solar panel shall operate at 12VDC nominal with a maximum output rating of 65 watts.
