Principles of operation
The Intelli-FLEX II system uses a disturbance sensitive sensor cable to detect
intrusion attempts. The sensor cable acts as a distributed microphone along a
perimeter fence. It can be used as an alarm sensor, anywhere that there is
significant noise caused by an intrusion event.
Sensor cables, installed on an existing fence, detect vibrations in the fence fabric.
The signals generated by the vibrations are continually evaluated by the
Intelli-FLEX II processor to determine if an alarm should be generated.
The vibrations of the fence could be the result of the weather or they could be
caused by an intruder attempting to penetrate the perimeter by climbing over,
lifting, or cutting through the fence. The Intelli-FLEX II processor evaluates the
signals and discriminates between actual intrusion attempts and weather related
events.
The Intelli-FLEX II system monitors the processor’s power level. If there is a
significant fluctuation in the power, a supervision alarm will be generated.
In most applications, the processor can be programmed by the user for optimum
performance. In addition, the system firmware can be modified at the factory, for
unusual applications.
Adaptive signal processing
The Intelli-FLEX II system continuously monitors and evaluates signals from the
sensor cables. To avoid nuisance alarms, the system compensates for signals that
are picked up by the sensor cables due to wind and rain.
