About this file
This document is a specification attachment for a skid-mounted variable message board system identified as the ADDCO 4x3H model. The specification outlines detailed requirements for a complete, fabricated, and delivered variable message sign system suitable for vehicular mounting and operation in all weather conditions while vehicles are in motion. The sign features a full matrix display with dimensions of 83 inches in width by 47.25 inches in height, capable of displaying 48 x 24 pixels with typical messaging of three lines of eight characters using 5 x 7 pixel fonts for 12-inch characters. Key display features include up to 1,200 feet visibility range, 0-100% manual and automatic LED intensity adjustment responsive to ambient light conditions, 30-degree cone of vision, and 16 LED amber flashers on the top edge. The system includes wireless control capability accessible from any smart device with password protection, message creation and storage for hundreds of messages, and automatic deploy and stow functionality.
The construction specifications require a 2" x 2" 11-gauge welded tubular steel frame with chromate-etched, non-reflective flat black powder-coated super surround back plate and a 1/8" 5052 aluminum sheet metal back plate. Required options include dual power linear actuators with auto up-down tilt mounting capability, limit switches, and position indicators; 200 watts of high-level solar power; four AGM batteries housed in a weatherproof plastic box; and a weatherproof 40-foot cable length. The system has been tested to withstand movement at speeds up to 65 miles per hour and complies with AASHTO wind load standards. The sign dial controller displays battery voltage and temperature information and supports arrow board operation.
