Intelli-FLEX Intelligent Fence Mounted Cable Type Sensor A Technological Breakthrough in Signal Processing for Cable-Type Sensors ARITECH
Introduction n Intelli-FLEX Cable-type intrusion detection sensor (Fence Mounted) –outdoor and interior applications Provides an alarm if an intruder –attempts to climb over the fence –attempts to cut through the fence –attempts to lift the fence fabric –attempts to penetrate wall (indoor version)
Typical Configuration n Dual zone deployment
Vocabulary n Glossary of terms Zone –The area or sector that is being monitored. Sensor cable –The proprietary coaxial transducer cable mounted on the fence. Non-sensitive cable –RG59/u coaxial cable that connects the processor to the sensitive cable. Processor –Outdoor mounted electronics required to analyze the sensor cable disturbance.
Equipment List n Intelli-FLEX System Elements Processor w/ enclosure and power supply & battery charger Program Module Sensor Cable Non-sensitive Cable Splice Kit Terminator Kit
Theory of Operation Triboelectric Effect –Minute movement (flexing) of the cable will produce a transfer of charge between conductors in the passive sensor cable. This measurable signal is monitored at one end of up to 1000 feet (300 m) of cable
Supervision Circuits n Sensor cable supervision Monitored by a small DC current Terminated by a 1M ohm resistor (EOL) If the cable is cut, shorted, or the processor enclosure is tampered with, a supervision alarm will be generated Hall Effect board mounted magnetic tamper switch.
Cable Splices n Terminator/Splice Kits UV protected and weather resistant Connect sensitive cable to non- sensitive cable, or sensitive cable to sensitive cable.
Theory of Operation n Processor Continually evaluates electrical signals generated by the sensor cable, and converts the information to a digital format. Through Adaptive Algorithms, the processor will alarm if an intruders is trying to –Cut the fence fabric. –Climb the fence. –Lift the fence fabric.
Key Hardware Features nStandard Dual Zone Processor n Microprocessor - Based n Backward Compatibility n Low Power Consumption n Full Lightning Protection n Handy Programming Module n Optional Weather Station
Low Power Consumption n Only 70mA of current required for normal two zone operation n Small internal Gel Cel (.8AH) battery provides minimum 8 hour backup
State of the Art Lightning Protection n Gas discharge tubes and transzorbs on all inputs and outputs provide maximum protection against lightning
Backward Compatibility n Intelli-FLEX uses existing E-Flex Cable, Splices, Gate Kits and Tie Wraps
Microprocessor Based n A powerful Motorola 68HC11 Series processor resides within each Intelli- FLEX system n Contains onboard A/D converters, memory and I/O dedicated to analyzing fence disturbance signals
Enhanced Features n Separate Threshold Adjustments for Cut and Climb for each zone Extremely important in lowering nuisance alarm in demanding situations n Learn Fence Mode n Internal Automatic Self Test
Key Software Features n Adaptive Algorithms n Ambient Compensation n Common Mode Rejection n Learn Fence Mode n Separate Cut & Climb Thresholds n Cipher Protected Adjustments n Optional Built-in Transponder
Theory of Operation n Processor (continued) Operates on 20VAC or 12VDC. Back-up battery provides over 8 hours of operation during power failures. Operationally tested from -30 o C to +70 o C.
Adaptive Algorithms n Sophisticated software code written to change or modify system parameters as new information is received
Ambient Compensation n Statistical analysis of digitized analog signals identifying properties inherent in wind & rain as they differ from cut & climb n Provides a Dynamic Threshold as weather events build, without sacrificing sensor performance or detection
Common Mode Rejection n An event qualifier that compares identical weather effects on adjacent zones to verify ambient compensation measures
Audio Option n Optional audio plug in board allows selection and monitoring of sensor cable signals. n Provides Listen-in capability n On-board line amplifier n Remotely switchable - Zone 1 or 2
Weather Station Option n Enclosure mounted weather sensor provides simple rain and wind verification to the processor via A/D converter
Multiplexer Option n Mux version of the Intelli-FLEX board provides data communication interface within the signal processor eliminating the requirement for outboard transponders or multiplexers
Theory of Operations n Options (continued) Weather Station –Provides weather data so the processor may make intelligent decisions. Self Test Terminator –Provides a permanent and convenient way to test zones remotely. No external power or wiring is required.
Preparing for Installation n Installation Planning Perimeter of installation Perimeter structure Mounting the processors Monitoring and power wiring.
Preparing for Installation n Site Survey Should be conducted before installing any system hardware To ensure optimum performance... –Mounting surface should be as stable as possible. –Fences must be cleared of vegetation and any other objects that disturb the structure. –A good earth ground should be achieved for the sensor processor.
Preparing for Installation n Site Survey (continued) Fence condition is critical to the trouble-free and efficient operation of the Intelli-FLEX sensor. –All fence framework should meet or exceed minimum specifications outlined in the installation manual.
Preparing for Installation n Determining a List of Materials The Intelli-FLEX sensor system is supplied in kits for installation convenience. –Single zone kits –Dual zone kits All Intelli-FLEX hardware components may be purchased individually. Options enhance the overall effectiveness of secure facilities.
Typical Configuration n Processor installation (single zone)
Installation n Junction devices Moisture proof Connects sensor cable to non-sensitive feed cable, or sensor cable to sensor cable, and holds termination resistor/card.
Installation n Sensor cable Mounted directly to the fence May be mounted in conduit Secured by UV protected tie wraps every 12 inches (.3m)
Installation n Sensor Cable (continued) Fences >8 feet (2.5 m) in height should have double passes.
Installation n Sensor Cable (continued) Fence at corner posts need additional sensitivity due to the rigidness of the fence.

Installation n Gates (continued) Unprotected gates
Installation n Gates (continued) Protected sliding gates may use EJ-8 Quick Disconnect Assembly
Remote Self Test n Remote Test Option Generator board (no local power reqd)
Calibration n Configuration Module
