The detector is single-position, passive, maskable, with linear-volume detection zone.
For protection of territories of military facilities I, II, III category perimeter from unauthorised entry through the perimeter fence by digging or jumping over the fence.
The detector operation principle is based on the detector signal processing unit registration of electrical signals arising in the sensitive element, laid along the protected boundary in the ground at a depth of 0.2 to 0.3 m, in case of attempts to dig or in case of impact on the ground in the detection zone (shovel blow, jump, etc.).
The sensing element is a combination of sensitive cables, a series connection of tribocable and vibration cable.
The displacement of the ground that occurs during digging creates local deformations of the tribocable. Electrification effect occurs in tribocable due to friction between cable elements (cores and insulation).
This generates an electrical signal.
