The SonoBlaster is a safety intrusion alarm that warns work crews and vehicle drivers of any impact, preventing crashes and injuries in work zones. The NCHRP 350-approved alarm mounts on barricades, cones, drums, delineators and A-frames. Upon impact, the intrusion alarm’s built-in CO2-powered horn blasts to signal workers that their protective zones has been violated, giving them critical reaction time to move out of harm’s way.
