<p>A picket barrier and intrusion sensing system including a plurality of vertically oriented, hollow picket elements (106) connected together by means of a lower rail (102) and an upper rail (100) that also serves as a communication conduit. Each picket element (106) has disposed therein a picket translation and/or deformation sensor (128) which is communicatively coupled to a supervised conductive loop (148) contained within the connecting rail (100). In the event that one or more of the pickets is deformed laterally or translated downwardly more than a predetermined distance, one of the internally contained sensors will cause a signal to be generated, transmitted to the supervised loop and in turn sensed by an associated alarm system.</p> |
