5.
Starting at the end of the zone that is already fixed to the fence, walk along to
each fence post and lift the sensor up to the required height. Loosely place a tie
wrap round the sensor and fence at the side of each post but do not tighten at
this stage. Continue to the other end of the zone so that the sensor is hanging
loosely along the final line to which it will be fixed. Ensure that sufficient slack is
left at corners.
6.
Return to the fixed end. Work towards the other end of the zone placing
intermediate ties every 200mm around the sensor and fence and manually
tightening them up. Do not use tie wrap guns as these cause the tie wraps to
break. Having the sensor supported at each post will make the task of placing
the sensor and tensioning the intermediate ties much easier.
7.
Once all the tie wraps are in place cut the excess tail off the tie-wrap using side
cutters ensuring that the sensor sheath is not damaged. Leave approximately
6mm of the tail protruding to allow for any slippage in the tie after tightening.

4.8 Coping With Sensor Damage

In the event that damage, whether accidental or intentional, is inflicted on the sensor,
the damaged section must be replaced with a new short section. This should be
inserted using GQCOMBO junction boxes at either end to ensure proper connections.
Figure 10 shows the arrangement of the damaged sensor replaced with a new section.
