Title (EN) CONDUITS PROTECTED AGAINST SABOTAGE,FOR SECURITY INSTALLATIONS AND INSTALLATION THEREOF WITHIN A PROTECTION NETWORK
(FR) CONDUITES A L"ABRI D"ACTES DE SABOTAGE, POUR INSTALLATIONS DE SECURITE ET LEUR INSTALLATION DANS UN GRILLAGE DE PROTECTION
Abstract: front page image
(EN)Pneumatic or hydraulic conduits which form a protection against intruders, are connected to a detector which registers a possible variation of the pressure and sets off an alarm. With a view to preventing an interruption, for example, by crashing of the conduits, said conduits comprise a core (2) made of hard and resistant material, for example one or a plurality of steel wires and preferably a steel cable. Upon a crushing attempt inner channels remain (4) due to the limited capacity of extrusion of the core and pressure variations may be sensed by the detector. These conduits are used for making networks which are under pressure and may be used as sensors for the peripheral protection or as a protection for doors or stores. They form an obstacle against the penetration into a space or a local thus protected, which may be entered only after previous destruction. The resulting leak causes a pressure drop and consequently the setting off of the alarm.
(FR)Les conduits pneumatiques ou hydrauliques qui forment une protection contre des intrus, sont relies a un detecteur qui enregistre une variation eventuelle de la pression et declenche une alarme. Afin de prevenir une interruption, par exemple, par ecrasement des conduits, ceux-ci comprennent un noyau (2) en matiere dure et resistante, par exemple un ou plusieurs fils d"acier et de preference un cable d"acier. Lors d"une tentative d"ecrasement il reste des canaux interieurs (4) dus a la capacite de fluage limitee du noyau et les variations de pression peuvent etre decelees par le detecteur. Les conduites servent a la confection de grillages qui sont sous pression et peuvent etre utilises comme clotures pour la protection peripherique ou comme protection de portes ou stores. Ils constituent un obstacle contre la penetration dans un espace ou local ainsi protege, qui ne peut etre franchi qu"apres destruction prealable. La fuite ainsi causee entraine une perte de pression et, consecutivement, le declenchement de l"alarme.
