Chapter 4: Maintenance

Recommended maintenance

The FlexZone sensor requires minimal maintenance to ensure proper operation.
However, setting up and following a maintenance schedule based on your site-
specific requirements can ensure proper detection performance, prevent
nuisance alarms and extend the operational lifetime of the system. The
frequency at which the maintenance should be scheduled depends on your
security requirements and on the installation environment. This section includes
the recommended maintenance activities along with suggested intervals.
1. Perform a visual inspection of the installation (once per month). Check for the
following:
•
fence condition - ensure the fence is in good condition and that there are
no loose panels, loose fittings or metal bits that can move with the wind
and cause nuisance alarms (a shake test in which you grip the fence
fabric in the middle of a panel and gently shake it with an increasing
motion can help identify any loose pieces),
•
there are no washouts or depressions under the fence,
•
vegetation beside and above the fence is cut back and cannot make
contact with the fence,
•
there is no loose sensor cable; the sensor cables are held snugly against
the fence fabric and the cable ties are holding the cable securely in place,
•
connectors and terminator enclosures are properly mounted according to
the installation instructions,
•
there is no corrosion or moisture inside the processor enclosure.
2. Physically test the system (once per week):
•
use a screwdriver to simulate a series of cut intrusions and verify that
alarms are declared and accurately located each time,
•
climb the fence at several locations and verify that alarms are declared
and accurately located each time.
3. Record a UCM sensor response plot (quarterly).
Connect the UCM to the processor and record a sensor response plot while
conducting tap tests of the protected fence. Note the environmental conditions at
the time of the recording.
Review the plot to examine the response and the ambient noise level, and
compare the plot to any previously recorded plots. Depending on the weather
conditions, the recorded plots should be quite similar. During inclement weather
the noise level will be higher, and during good weather with very little wind, the
noise level should be extremely low. If there is a significant amount of noise
indicated during good weather, examine the cable and cable connections for
possible problems.
