The detector is designed to protect territories from unauthorised entry through the perimeter fence by the following methods:
- climbing without improvised means;
- climbing with the help of an extension ladder with support on the fence;
- breaching the integrity of the fence elements;
- dismantling of the CE;
- violation of the CE integrity.
The detector operation principle is based on registration by the signal processing unit of electrical signals arising in any of the sensitive elements and in the places where the sensitive element is rigidly attached to the fence ("stress nodes") in case of unauthorised mechanical impact on the fence elements. In the signal processing unit the signals are filtered and amplified. In case the signal exceeds the threshold value, an alarm notification is generated in the form of opening the contact of the output optorelay.
