CORRECTIVE ACTION
13. TAUT WIRE FENCE SENSOR FAILURE (Figure 3-22)
NOTE
Refer to SAIG for details on the Taut Wire Fence Sensor.
Step 1. Make a visual inspection of fence and cabling for cut wires or cables.
If cut wires or cables are found, replace.
If no visible defects are found, go to step 2.
Step 2. Starting at last sensor post in section, connect MAGTEST 90/1 testing device to sensor post's test points.
Switch function selector to VOLTAGE position. Switch status selector to zone position. Using a screwdriver or
similar tool, slight tap each taut wire several times. No audio signal should be heard.
If an audio signal is heard, check for faulty wiring to sensor; or sensor connected to taut wire is too sensitive.
Repair or replace as necessary.
If no audio signal is heard, go to step 3.
Step 3. Switch status selector to POST position. Activate every sensor in post. An audio signal indicates correct
activity of activated sensor.
If no sound is heard, sensor has not been activated due to a faulty sensor. Replace sensor unit. (para 3-127)
