13.3 Cut Sensitivity

The right hand set of controls shown on Figure 26, sets the sensitivity of the system to
intrusions where an attack is being attempted by cutting through the fabric of the fence.
Correct setting of the link in the Hi, Med or Low position and with the potentiometer
adjusted correctly will result in an alarm being generated provided more that one cut in
the fabric of the fence is made and the time between cuts is less than 20 seconds. An
event LED, shown in Figure 25, shows red when a cut is detected.
The setting of these controls should be done with the link for climb detection removed.
The 'FENCE' setting link has NO effect on the CUT detection
