Location calibration for Split configurations:
To ensure location accuracy on the map display, and for alarm reporting, you must conduct
location accuracy testing to match site features and zone boundaries to cable length. This location
accuracy testing is then used for location calibration. Beginning at Location 0, proceed along the
fence conducting a series of 3 tap tests to create 3 alarms at each feature and zone boundary.
1.
Conduct a series of 3 tap tests to create 3 alarms at the Sensor 1 end module (location 0)
(i.e., the detection start point or 0 footmark of detecting cable). Wait at least 15 seconds
between each test. Record the GPS coordinates and a brief description of the location and the
start time of each test on the calibration sheet. This will be the start point for the first zone.
2.
Proceed along the fence to the first feature or to the designated end point of the first zone.
Conduct a series of 3 tap tests to create 3 alarms. Wait at least 15 seconds between each test.
Record the GPS coordinates and a brief description of the location and the start time of each
test on the calibration sheet.
3.
Continue this process until reaching the end of the detecting section of sensor cable for
Sensor 1 (i.e., at the point where the lead cable runs from the fence to the sensor unit). This
should also be the start point of the detecting sensor cable for Sensor 2. The tap tests at this
location may cause alarms on both Sensor 1 and Sensor 2.
4.
Conduct as many tap tests as required between the fence and the sensor unit to identify the
lead cable for Sensor 1 and Sensor 2.
5.
Return to the fence (beginning of Sensor 2 detecting cable) and continue this process until
reaching the end of the detecting cable for Sensor 2 (Sensor 2 end module, Location n on
Sensor 2).
6.
Go to the Log sub-panel, and record the locations of the alarms that were generated during
the tap tests. Calculate the average location of each set of 3 tap tests (alarms) for each feature
and zone boundary location and record the result in the Location/calibration table.
7.
Make a copy of the completed Location/calibration table and keep it in a safe place.
Calibration setup for Line configurations
Calibrating the Set Start location (Line configurations)
1.
Set the Sensor 1 Offset = 0, Sensor 1 Scale = 1, Sensor 2 Offset = 0, Sensor 2 Scale = 1.
2.
Proceed to a position 10 m (33 ft.) from the start point of the sensing cable. Conduct three tap
tests at this location, waiting at least 15 seconds between tests (see
Figure 79 Tap test location - Set Start (line configuration)
Note
The FiberPatrol cable between the Sensor Unit and the start point of the
perimeter fence must be set to non-sensing.
Note
The location for Sensor 1 and Sensor 2 will nominally be the same.
