Figure 73: Setting individual cable segment Thresholds
Globally set Threshold (6 dB below profile)
Independent Threshold for high security Zone 2
(12 dB below profile)
Figure 73 above illustrates a cable, which has been split into 5 segments and 3
zones. The first segment is non-detecting cable at the processor location. The
fifth segment is past the end point of detecting cable. Segments 1 and 3 (Zones 1
and 3) use the globally set threshold of 6 dB below the profile. Segment 2 (Zone
2) is a high threat area and the threshold has been lowered to 12 dB below the
profile.
Segment threshold setting procedure
1. Select the defined segment to which you will apply a cable segment
Threshold.
2. Use the Threshold (dB) spin control to set the Threshold for the selected
segment.
3. If required, repeat this procedure to set a cable segment Threshold for other
segments (or Zones) as specified in the site plan.
4. Repeat this procedure for the B side sensor cable.
5. Save the UCM file and download the configuration data to the processor.

Intrusion simulations

To test the FlexZone sensor you conduct simulations for both cut and climb
intrusions. The easiest method for simulating a cut intrusion is to tap the fence
with the blade of a medium sized screwdriver. Hold the screwdriver by the
handle, and flip your wrist to bring the blade into contact with the fence. The
metal on metal contact generates an impulse that is similar to the cutting of a
fence wire.
Rather than tapping the fence, you can also simulate a cut intrusion by weaving a
length of fence wire into the panel and then cutting the inserted wire. Both
methods generate a signal that is similar to the response of an actual cut
