Introduction

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

Dual zone deployment

Vocabulary

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

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

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

Terminator/Splice Kits• UV protected and

weather resistant• Connect sensitive

cable to non-sensitive cable, or sensitive cable to sensitive cable.

Theory 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 to–Cut the fence fabric.–Climb the fence.– Lift the fence fabric.

Key Hardware Features

“Standard” Dual Zone Processor Microprocessor - Based Backward Compatibility Low Power Consumption Full Lightning Protection Handy Programming Module Optional Weather Station

Low Power Consumption

Only 70mA of current required for normal two zone operation

Small internal Gel Cel (.8AH) battery provides minimum 8 hour backup

State of the Art Lightning Protection

Gas discharge tubes and transzorbs on all inputs and outputs provide maximum protection against lightning

Backward Compatibility

Intelli-FLEX uses existing E-Flex Cable, Splices, Gate Kits and Tie Wraps

Microprocessor Based

A powerful Motorola 68HC11 Series processor resides within each Intelli-FLEX system

Contains onboard A/D converters, memory and I/O dedicated to analyzing fence disturbance signals

Enhanced Features

Separate Threshold Adjustments for Cut and Climb for each zone Extremely important in lowering nuisance alarm in demanding situations

“Learn Fence” Mode Internal Automatic Self Test

Key Software Features

Adaptive Algorithms™ Ambient Compensation Common Mode Rejection “Learn Fence” Mode Separate Cut & Climb Thresholds Cipher Protected Adjustments Optional Built-in Transponder

Theory 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

+70 o C.

Adaptive Algorithms™

Sophisticated software code written to change or modify system parameters as new information is received

Ambient Compensation

Statistical analysis of digitized analog signals identifying properties inherent in wind & rain as they differ from cut & climb

Provides a “Dynamic Threshold” as weather events build, without sacrificing sensor performance or detection

Common Mode Rejection

An event “qualifier” that compares identical weather effects on adjacent zones to verify ambient compensation measures

Audio Option

Optional audio plug in board allows selection and monitoring of sensor cable signals.

Provides “Listen-in” capability On-board line amplifier Remotely switchable - Zone 1 or 2

Weather Station Option

Enclosure mounted weather sensor provides simple rain and wind verification to the processor via A/D converter

Multiplexer Option

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

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

Installation Planning• Perimeter of installation• Perimeter structure• Mounting the processors• Monitoring and power wiring.

Preparing for Installation

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

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

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.
