About this file
This is a specification document for a Skid Mount ADDCO 4x3H Variable Message Board being procured by the State of New Hampshire. The specification outlines a complete, fabricated, wired vehicle-mounted display system designed for operation in all weather conditions, including while the vehicle is in motion. The unit features a full matrix 48 x 24 pixel display measuring 83 inches wide by 47.25 inches high, capable of displaying up to 3 lines of 8 characters using 5 x 7 pixel fonts for 12-inch characters. The display system must include 16 LED amber flashers on the top edge and support visibility up to 1,200 feet with a 30-degree cone of vision. The sign requires dual power linear actuators with a tilt mount featuring auto up/down functionality, limit switches, and position indicators to ensure proper deployment and storage positioning.
The specification mandates that the variable message board be constructed with a 2-inch by 2-inch 11-gauge welded tubular steel frame with chromate-etched, flat black powder-coated finish, and include a weatherproof main bus with positive lock connectors rated for vehicles traveling up to 65 miles per hour. The system must incorporate 200 watts of solar power capability with four AGM batteries housed in a weatherproof plastic box, a 40-foot weatherproof cable length, and a wireless controller accessible from any smart device with password protection. The controller must enable message creation, editing, storage of hundreds of messages, battery voltage and temperature display, and auto deploy and stow functions with arrow board operation capability. All LED modules must be self-contained, environmentally sealed units with high-density 8x12 pixel arrays offering 0 to 100 percent manual and automatic intensity adjustment in response to ambient light conditions detected by front and rear facing sensors.
