CONDENSIVE DETECTION DEVICE


sredstvo_obnaruzheniya_nuklon4-01.jpg


Goal


The detection device "Nucleon" is designed to protect the facility perimeter by applying a special alarm visor fence (SAVF).

The device provides perimeter protection at length of up to 1000 m (two sides of 500 m).


Method


The method is based on the registration of the electric capacity flank change of the protected part of the fence due to the SAVF violator touch in attempt to penetrate or destruct the fence.


Advantages


  • The device registers attempts to penetrate the SAVF fence with a bare hand touch, in cotton gloves or with ladder when attempting to overcome or destroy the barrier.


  • The device does not require seasonal sensitivity adjustment and its sensitivity automatically adjusts to both environmental and SAVF.


  • The device operates under the following environmental conditions:


    • - temperature from – 50° c and +50° c;


    - weather factors (frost, dew, rain);


    - dynamic effects of sand and dust, rain;


    - electromagnetic impact of thunderstorms (lightning/fall rise time pulse-8/20 µs; current amplitude-150 A).


    - vibration impact in the frequency range from 1 to 35 Hz with of 0.5 g max acceleration


    - POWER TRANSMISSION LINES with voltage up to 220 kV at a distance of more than 10 m from the SAVF;


    - POWER LINES crossing with voltage up to 220 kV over the central alarm post at 30 to 90 degrees angles;


    - portable radios (HF, VHF and UHF) and cellular phones at a distance of more than 2 m from the SAVF and within a radius of more than 10 m from the SASSF installation;


    - the movement of wheeled and tracked vehicles at a distance of more than 3 m from the fence alarm;


    - passage of people (up to three people) at a distance of more than 1 m from the SAVF;


    - forest at a distance of more than 2 m, single trees at a distance of more than 1 m from the fence alarm;


    - rail traffic at a distance of more than 10 m from the SAVF.



  • The design of the device provides a protection level IP54 in accordance with SS 14254


    • Parameters


    • The device is powered from a DC source voltage from 9 to 36 in.


    • Appliance power consumption 3 W.


    • Trigger signal duration: 4 ± 1 c.


    • Time ready since power is on- no more than 10 seconds.
      With power cut the device produces a signal similar to the trigger signal, and the signal duration equal to the time of power cut.


    • Remote control is available.


    • Detectability -0,95 with 0,9 confident probability.


    • Average time for false positive -not less than 2000 hours.


    • Second degree of rigidity for electromagnetic compatibility according to SS R50009-2000.


    • Birds and small animals deterrent effect attempting to catch the fence due to pulsing power in
      alarm part of the visor.
