Abstract

An entrance denial security system comprises an entrance barrier closing an entrance into a secured area having a plurality of structural tubular elements with hollow cores forming a rigid integral barrier. At least one optical fiber sensor line is laced through the hollow cores of the structural elements for detecting a fault condition signifying an unauthorized intrusion attempt. A processor in communication with the fiber sensor line generates a fault signal in response to a fault signal level. A communication device operatively associated with the processor communicates the fault signal and an alarm. The system also includes a plurality of tubular elements lying a common plane and the sensor line is routed through the tubular elements. In one instance, the tubular elements are PVC pipe.
