Alert Max®Alert Max is a system consisting of a changeable message sign and an AM Highway Advisory Radio (HAR) on a single, solar powered trailer. Text messages are displayed on a changeable message sign and audio messages are broadcast to motorists, providing drivers enough time to merge or take an alternate route.
Alert Max utilizes solar power, which provides dependable service around the clock and during extended periods of inclement weather. Messages can be changed quickly and remotely should conditions vary.
Alert Max has the ability to save messages for years with no external power source. That means no fuel, no landline utilities, no noise, no maintenance and no lost messages. Even in outdoor storage, Alert Max is charging the batteries so you can be set up and on the air in minutes.
