Intelli-FLEX™
Intelligent Fence Mounted
Cable Type Sensor
A Technological Breakthrough
in Signal Processing for
Cable-Type Sensors
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 nonsensitive 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 IntelliFLEX 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.
