Installing cable on weld-mesh fence
Note:
Follow the installation instructions and use the height recommendations for
chain-link fences when installing sensor cable on weld-mesh fence.
• Install the sensor cable on the secure side of the fence (the side opposite the
threat).
• Sensor cable being installed on the same side of the fence as the horizontal
wires should be placed directly below the horizontal wire and attached every
25 cm.
• Sensor cable being installed on the opposite side of the fence as the
horizontal wires should be attached at the intersection points of the two wires
every 25 cm.

Double pass cable installation
For double cable pass installation use both sides of one processor for the upper
and lower cable runs. The FlexZone sensor monitors the received signals from
both sensor cables to determine intrusion activity. Therefore, it is critical that the
features and lengths of both cables are properly matched. Figure 29 below
illustrates the double pass concept for a single processor installation. For multiple
processor installations the upper cables and lower cables of two processors are
joined by spice kits (see Figure 8 on page 12). Refer to Figure 29 and "Installing
cable on chain-link fences" on page 24 to attach FlexZone sensor cable in a
double pass configuration. The cable spacing for a double pass configuration is
1/3 the fence height for the lower pass and 2/3 the fence height for the upper
pass. If the double pass is required because the fence has a middle rail, then the
lower pass should be 1/2 way between the middle rail and the ground, while the
upper pass should be 1/2 way between the middle rail and the top of the fence.
