SECURITY DEVICE ON THE BASIS OF SPIRAL FENCE Russian patent published in 2018 - IPC E04H17/02 

FIELD: security systems.

SUBSTANCE: invention relates to alarm barriers based on the spiral elements and is intended for protection of the objects perimeters and extended guard lines on flat and rugged terrain. Technical result is achieved by using a security device on the basis of a spiral barrier containing spirals oriented relatively to each other with production of a three-dimensional shape, wherein the turns of adjacent spirals are connected to each other in pairs at their points of contact located on the same straight line along the spiral length, at that, it contains a cable sensing element, as which a metal rope with a built-in optic module with fiberoptic is used, which is to be fixed at points with an angular distance of 0±90 degrees relative to the equator of this spiral, wherein as the spiral equator a horizontal plane is meant passing through the spiral coil center of mass.

EFFECT: technical result of the invention is an increase in the security device alarm and barrier properties due to the implementation of cable sensing elements in the form of a steel rope with a built-in optical module with fiberoptic.
