Work-zone intrusion alarm

SonoBlaster! Work Zone Intrusion Alarm for barricades, cones, drums, delineators, A-frames and other work zone barriers. Upon impact by an errant vehicle, the SonoBlaster’s CO2–powered horn instantly blasts at 125 decibels for 15 seconds signaling that a work zone has been violated. Critical alignment is not required (like beam devices), and no receiver units are required (each device operates independently). SonoBlaster is an FHWA NCHRP 350 Category II accepted safety device (code WZ-131).
