6. Select the Record button and have the tap tester begin the tests at the farthest point on the
gate from the GSM.
7. Continue the tap testing moving closer to the GSM and then away from the GSM on the
opposite side until the gate has been fully tested.
• Each series of 3 taps should cause an alarm.
• The tap tests that are farthest away from the GSM should have the lowest magnitude
response. If tests closer to the GSM have lower magnitudes, inspect the fence for loose
fabric or other issues.
• If any of the test taps do not cause a response above the Event Threshold, repeat the
tests at that location.
• If the repeated tests remain below the Event Threshold, lower the Event Threshold and
repeat the tests.
• If all of the tests are significantly above the Event Threshold, raise the Event Threshold
and repeat the tests.
• Continue this process until each series of 3 taps causes an alarm.
You can adjust the GSM detection parameters to meet your site-specific security requirements.
Once the sensor is setup, calibrated and operational you should monitor the NAR to ensure
optimum settings. Minor adjustments to the Target Filters and the Event Threshold can be used to
prevent nuisance alarms caused by environmental factors and fence condition.
