13. Points to Consider The fence A chain link fence can form a satisfactory boundary around the protected site however steps must be taken to prevent digging under the fence especially in areas where the ground soil is sandy and loose One of the best protective measures to take is to embed a concrete skirt around the bottom of the fence all the way around the perimeter making digging difficult or burying a layer of fiber along the bottom of the fence The loopback deployment also protects against digging or tunneling under the fence The gate A strategy must be created for ensuring the gate is protected This strategy will depend greatly on the type of gate involved For detailed information on protecting a gate see Protecting Gates in Chapter 4 Buried Zone 1 Guardhouse Buried Zone 2 Insensitive Leads Fence Zone 2 Fence Zone 1 Junction Box 2 Junction Box 1 FD 340 Series User s Reference Manual 3 30 The rock formation While the rock formation provides the perfect natural barrier it is conceivable for a climber to scale the rocks and drop down into the protected site making a fence impractical for protection at the base of the formation Instead steps must be taken to ensure that intruders coming down from the rocks are detected Separate protection zones can be created at the base of the rock formation using buried sensor cable and audible alarms or other indicators triggered off the A
