ABSTRACT:
An extremely reliable, easily portable perimeter alarm system. It is comprised of a light beam controlled radio transmitter and personal warning devices capable of individually warning preoccupied highway workers of the imminent danger present when an errant vehicle violates the established perimeter of a work site. This warning will allow the workers to take evasive action and potentially avoid injury and/or death. It is also the object of this invention to allow for an extremely reliable, easily portable perimeter penetration alarm system that can be utilized in other appropriate settings by security guards, military personnel, etc., and which would provide for confidential notification to such personnel that a temporarily established portable perimeter line had been violated.
