1Intelli-FLEX™ Intelligent Fence Mounted Cable Type Sensor ARITECHIntelli-FLEX™ Intelligent Fence Mounted Cable Type SensorA Technological Breakthrough in Signal Processing for Cable-Type Sensors
2Introduction Intelli-FLEX™ Cable-type intrusion detection sensor (Fence Mounted)outdoor and interior applicationsProvides an alarm if an intruderattempts to climb over the fenceattempts to cut through the fenceattempts to lift the fence fabricattempts to penetrate wall (indoor version)E-Flex II is a passive sensor.Sensitive coaxial cable is mounted directly on the fence line.
4Vocabulary Glossary of terms Zone Sensor cable Non-sensitive cable The area or sector that is being monitored.Sensor cableThe proprietary coaxial transducer cable mounted on the fence.Non-sensitive cableRG59/u coaxial cable that connects the processor to the sensitive cable.ProcessorOutdoor mounted electronics required to analyze the sensor cable disturbance.
5Equipment List Intelli-FLEX™ System Elements Processor w/ enclosure and power supply & battery chargerProgram ModuleSensor CableNon-sensitive CableSplice KitTerminator Kit
6Theory 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
7Supervision Circuits Sensor cable supervision Monitored by a small DC currentTerminated by a 1M ohm resistor (EOL)If the cable is cut, shorted, or the processor enclosure is tampered with, a supervision alarm will be generatedHall Effect” board mounted magnetic tamper switch.
8Cable Splices Terminator/Splice Kits UV protected and weather resistantConnect sensitive cable to non-sensitive cable, or sensitive cable to sensitive cable.Explain the theory behind low DC voltageNote that sensitive cable can be connected to either sensitive coax or non-sensitive coax
9Theory of Operation 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 toCut the fence fabric.Climb the fence.Lift the fence fabric.
10Key Hardware Features “Standard” Dual Zone Processor Microprocessor - BasedBackward CompatibilityLow Power ConsumptionFull Lightning ProtectionHandy Programming ModuleOptional Weather Station
11Low Power ConsumptionOnly 70mA of current required for normal two zone operationSmall internal Gel Cel (.8AH) battery provides minimum 8 hour backup
12State of the Art Lightning Protection Gas discharge tubes and transzorbs on all inputs and outputs provide maximum protection against lightning
13Backward Compatibility Intelli-FLEX uses existing E-Flex Cable, Splices, Gate Kits and Tie Wraps
14Microprocessor BasedA powerful Motorola 68HC11 Series processor resides within each Intelli-FLEX systemContains onboard A/D converters, memory and I/O dedicated to analyzing fence disturbance signals
15Enhanced FeaturesSeparate Threshold Adjustments for Cut and Climb for each zone Extremely important in lowering nuisance alarm in demanding situations“Learn Fence” ModeInternal Automatic Self Test
16Key Software Features Adaptive Algorithms™ Ambient Compensation Common Mode Rejection“Learn Fence” ModeSeparate Cut & Climb ThresholdsCipher Protected AdjustmentsOptional Built-in Transponder
17Theory of Operation 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 o C.
18Adaptive Algorithms™Sophisticated software code written to change or modify system parameters as new information is received
19Ambient CompensationStatistical analysis of digitized analog signals identifying properties inherent in wind & rain as they differ from cut & climbProvides a “Dynamic Threshold” as weather events build, without sacrificing sensor performance or detection
20Common Mode RejectionAn event “qualifier” that compares identical weather effects on adjacent zones to verify ambient compensation measures
21Audio OptionOptional audio plug in board allows selection and monitoring of sensor cable signals.Provides “Listen-in” capabilityOn-board line amplifierRemotely switchable - Zone 1 or 2Explain that the audio module is providing the actual disturbance signal
22Weather Station Option Enclosure mounted weather sensor provides simple rain and wind verification to the processor via A/D converter
23Multiplexer OptionMux version of the Intelli-FLEX board provides data communication interface within the signal processor eliminating the requirement for outboard transponders or multiplexers
24Theory of Operations Options (continued) Weather Station Provides weather data so the processor may make intelligent decisions.Self Test TerminatorProvides a permanent and convenient way to test zones remotely. No external power or wiring is required.
25Preparing for Installation Installation PlanningPerimeter of installationPerimeter structureMounting the processorsMonitoring and power wiring.Perimeter of installationHow many gates, what is the distance, large openings.Perimeter structureWhat is the condition of the fence. Center of panel, should deflect 2-3 inches with 30 lb. pull.Mounting the processorsLocate positions at least 15 feet away from the fence line.Monitoring and power wiringMust me run to each processor.
26Preparing for Installation Site SurveyShould be conducted before installing any system hardwareTo 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.Earth ground is highly recommended.Note that if two different ground planes are present, nuisance alarms will occur.
27Preparing for Installation 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.
28Preparing for Installation Determining a List of MaterialsThe Intelli-FLEX™ sensor system is supplied in kits for installation convenience.Single zone kitsDual zone kitsAll Intelli-FLEX hardware components may be purchased individually.Options enhance the overall effectiveness of secure facilities.
