1System Description
The system operates by means of a Flexiguard sensor cable, which can be attached to fences.
The characteristics of the cable enable it to detect vibrations occurring at any point along its full
length. The cable has equal sensitivity along its whole length.
In the event of an intruder attempting to force entry the vibrations caused by this intrusion are
detected by the sensor cable and passed to the analyser. The analyser converts the vibrations
into alarm and audio signals, which are sent back to the control unit. The maximum zone length
is 300m per analyser.
The main control unit upon receipt of a signal from an analyser activates an audio and visual
alarm. The operator is able to listen to the vibrations in order to distinguish the nature of the
alarm. Any interference with the sensor cable itself will cause an alarm.
The Flexiguard outdoor analyser has a unique Automatic Environmental Control (AEC) which
can distinguish between vibrations caused by climatic conditions and an intruder. This
dramatically reduces the nuisance alarms caused by wind and rain.
The analysers have built-in test facilities, which allow the installer to set-up, and fault find the
analyser without the need for specialised test equipment.

2Fence Condition
In order for the system to work reliably, the fence must be in a reasonable condition so that
there are no unwanted sources of vibration.
Undergrowth and tree branches should be cleared away at least 1m from both sides of the
fence as this will cause vibrations in the fence in windy conditions.
The most common sources of unwanted vibrations are: -
1) Undergrowth
2) Loose fence posts
3) Barbed wire dangling against the fence
4) Broken strainer wires in chainlink fences
5) Loose fence fabric
6) Loose mounting bolts in weldmesh and palisade fences
7) Rattling gates
8) Loose gate bolts and padlocks
9) Tree branches
If any of the above or any other sources of vibrations are found, they should be corrected before
installation commences.
3Mounting the Analysers
The signal analyser can be fixed to a fence post by the use of an FS-205 mounting kit or in a
suitable position off the fence. Counterbored holes outside the gasket area are provided for
mounting the analyser.
When two zones meet, it is advisable to mount two analysers together so that each zone runs in
opposite directions. This allows one control cable to feed two analysers thus reducing the
number of joints in the control cable. It also makes maintenance easier as two analysers can be
serviced from one location.

4Sensor Cable Installation
4.1 Chainlink & Weldmesh Fence
Clip the Sensor Cable to the middle of the fence with cable ties every 100mm. The cable should
be clipped to the fence fabric at least 50mm away from any fence straining wire. The cable ties
should not be pulled so tight as to unduly deform the sensor cable.
It is advisable to increase the detection sensitivity at fence straining posts and corners as shown
below.
4.2 Terminating Sensor Cable
The sensor cable should be terminated in the FS-410 termination box. The termination
resistance value is 1 M Ohm.
The screen of the sensor cable should be connected into the terminal that is connected to the
internal screening of the termination box. This terminal has two black wires connected to it. The
termination box can be secured to the fence using the large cable tie supplied.

4.3 Jointing Sensor Cable
The sensor cable can be joined using the FS-420 cable jointing box.
Twist the two screens together and connect them into the terminal that is connected to the
internal screening of the jointing box. This terminal has two black wires connected to it. Twist
the two centre wires together and connect them into the other terminal. The cable jointing box
can be secured to the fence using the large cable tie supplied.

5Gate Wiring Using FS-460/FS-461 Gate Loop Kits
5.1 Chainlink Gates
Gate loop kits are used to attach the sensor cable to gates as shown below. The length of
sensor cable on the gate should be adjusted so as to give the same sensitivity as the rest of the
fence.

5.2 Gate Bypass Switch
Gate bypass switches are used to allow access through a gate while the rest of the fence is still
alarmed. It does this by switching off the alarm for the zone that the gate is in. The switch is
mounted on the fence post next to the gate. A 3-core cable is required between the switch and
the analyser.

6Wiring The Analysers
A multipair control cable should be run around the perimeter and jointed at each analyser or pair
of analysers using an FS-450 joint box. Each analyser needs 5 wires from the joint box. The
wires should be connected as shown in the diagram on page 11. Make the corresponding
connections back at the alarm panel.
Strip back the sensor cable by 30mm. Measure the resistance of the cable between the two
conductors. You should read 1 M ohm, which is the value of the termination resistor. Also
measure the resistance from the screen of the sensor cable and any metal on the fence. It
should be completely open circuit. After these checks have been successfully completed
connect the sensor cable into the connector.
7Setting Up The Analyser
7.1 Initially set all controls and switches as follows:
Climb Cut
Impulse Count 32
Time Window 2 Seconds 2
Sensitivity 00
S2, S3 Off
S4 Chainlink Off
Weldmesh Off
(note. S1 is not used)
7.2 Apply power to the Analyser and check that the voltage across terminals ) and +is
between 15 and 21 VDC.
All LED’s should go out after 30 seconds. If any LED remains lit, refer to Analyser Fault
Finding.
7.3 Climb Setting –The climb must be set up before the cut circuit. Whilst someone is
climbing the fence, slowly increase the Climb Sensitivity until the Impulse LED starts to
flash when the fence is climbed. If the Impulse LED does not flash, use S2 and S3 to
increase the gain to the next setting as shown on page 11. Again turn the sensitivity to 0
and slowly increase the sensitivity until the Impulse LED flashes when the fence is
climbed.

7.4 Climb the fence and check that the Time Window LED lights and that the Alarm LED
light showing that the alarm has been activated. With the initial settings of Impulse
Count –3 and Time Window –2 seconds, the Analyser has to detect 3 impulses within a
Time Window of 2 seconds to activate the alarm.
If the alarm activates, increase the Impulse Count to 4and again check that the alarm
activates when climbing the fence.
If the alarm does not activate, reduce the Impulse Count back to 3.
If the alarm does not activate when the Impulse Count is set to 3 increase the Time
Window to 3 seconds and climb the fence again.
The Impulse Count and Time Window should be set so that reliable climb detection is
achieved.
7.5 Check the operation of the Automatic Environmental Control (A.E.C.) shake the fence, but
do not shake it so hard as to start the Impulse LED flashing. The A.E.C. LED should light
up and go out after 5 to 10 seconds of ceasing to shake the fence.
7.6 Cut Setting
In order to simulate a cut; tap the fence sharply with a screwdriver. With the Cut
Sensitivity set to 0, tap the fence at 1 second intervals and slowly increase the Cut
Sensitivity until the Cut Impulse LED flashes every time the fence is tapped. The Time
Window LED will also light up for the time period set by the Time Window Switch. Each
position is a multiple of 5 seconds, e.g. position 1 gives 5 seconds, position 2 gives 10
seconds, etc, up to a maximum of 75 seconds.
Set the Impulse Count to the required number of cuts detected before the alarm is
activated and set the Time Window to the required time period over which the cuts are to
be detected.

8Final System Tests
Each zone should now be tested to ensure that an alarm and audio signal is being received by
the control unit.
Ensure that the zone to be tested is switched on. Switch the selector switch to that zone and
adjust the volume control so that the background noise can be heard.
Listen to the audio while someone attempts to climb the fence. The alarm should be activated
and you should be able to hear the person climbing. If there is no alarm or audio, check the
operation of the analyser and the cabling. These tests should be repeated for each zone. The
system is now ready for use.
9Maintenance
Each zone should be checked for sensitivity once per week, by the security staff. This can be
done by someone attempting to climb the fence and checking that the appropriate alarm is
activated at the control unit.
Every three months the fence should be inspected visually to ensure that the fabric of the fence
is still secure.
Also check the cable ties and replace any damaged or broken ties.

10Analyser Fault Finding
Check that the voltage across the 0 and + connection is between 15 and 21 VDC. The unit may
not operate correctly if the voltage is below 15 VDC.
Check that the Cable O/C and S/C LED’s are extinguished. If either are illuminated check the
cable resistance is 1M ohm. To test the operation of Cable O/C and S/C LED’s apply a short
across the fence cable. The Cable S/C and Alarm LED should light showing that the cable is
short and the alarm has been activated. On disconnecting the sensor cable from the connector
the Cable O/C and Alarm LED should light and go out when the cable is reconnected.
The A.E.C. LED is permanently lit, disconnected the sensor cable and measure the resistance
from the screen of the sensor cable and any metal on the fence. It should be completely open
circuit. If it is not open circuit, check the wiring of the End of Line Termination and Joint Boxes
in the cable including Gate Loops. Make sure that the coax of the Direct Burial Feeder Cable
has been used for connection under any gates. Also, check the sensor cable to make sure it
has not been damaged during installation.
To test the alarm output, disconnect the wires connected to the Alarm Terminals A and A and
connect an ohm meter across the Aand Aterminals. The reading should be 0 ohm. Short the
sensor cable so that the Cable S/C and Alarm LED’s are lit. The resistance should now be
greater than 10M ohm. The resistance should return to 0 ohm on removing the short.
The audio output of the analyser can be tested by removing the wire from the Sound terminal
and connecting an earpiece or telephone handset across the S and 0 terminals. The audio
signal can then be heard when someone climbs the fence. The audio output level should be
approximately 1V p.p.
If any of the above tests fail, replace the analyser.
