1 System planning
Introduction
The FlexZone fence protection system uses loose-tube coaxial sensor cables mounted on a fence
to detect vibrations caused by climbing, cutting, lifting, or otherwise disturbing the fence fabric.
Each FlexZone processor can monitor the activity from one or two sensor cables, each up to
300 m (984 ft.) long, and will report the alarm status of up to 60 software defined sensor zones.
FlexZone will locate the source of a disturbance to within ± 3 m (10 ft.). A single pass of sensor
cable can protect a high quality chain-link fence with no middle rail, up to 4.3 m (14 ft.) high.
Additional passes of sensor cable are recommended for chain-link fences that are higher than
4.3 m.
There are two models of the FlexZone processor available. Both models process alarm data the
same way. However, the FlexZone-4 processor supports up to 4 software defined alarm zones, but
does not report target location. The FlexZone-60 processor supports up to 60 distinct alarm zones
and reports target location.
This Product Guide covers FlexZone installation and setup for chainlink, welded-mesh, expanded
metal and palisade fences.
Installation overview
Installing a FlexZone system is a four step process:
1. Plan and design the system.
2. Inspect and if necessary, repair the fence and the surrounding area.
3. Install the sensor cable, processor and enclosure.
• ground rod (if required)
• alarm communication wiring
• power supply
4. Setup and calibrate the system.

Security factors
Security factors
There are many important factors to consider when planning a fence-mounted perimeter security
system:
• Fence height - The fence must be high enough to present an effective barrier to climb-over
intrusions. It should also include climb-over deterrent hardware such as barbed wire or razor
ribbon (for flexible fences). Rigid fence types should incorporate a climb over deterrent in their
design (pointed stakes or pales). Senstar recommends that the minimum fence height for a
FlexZone installation on a flexible fence type is 2.5 m (8 ft.). For rigid fence types the minimum
recommended fence height is 2 m (6.5 ft.).
• Fence condition - FlexZone detects intrusions by picking up the minute vibrations or fence
noise caused by an intrusion attempt. Therefore, the fence must be in good condition to
prevent any metal on metal contact or vibrations caused by environmental factors. It may be
necessary to upgrade the perimeter fences to ensure they present sufficient barriers against
climb over and crawl under intrusions. If you are not sure of the suitability of your fence for a
FlexZone sensor, Senstar recommends hiring a local fencing contractor to inspect, and if
required, repair the fence.
• Probability of detection (Pd) vs. nuisance alarm rate (NAR) - With a fence-mounted intrusion
detection system there is always a trade-off between the probability of detection and the
nuisance alarm rate. A properly calibrated system will provide a high Pd and will minimize the
NAR.
• Alarm assessment/response - What happens when the system triggers an alarm? Can the
alarm be assessed visually? Does the site include CCTV coverage to verify the event?
Senstar recommends engaging a security consultant to discuss the available methods of
alarm assessment. To ensure maximum confidence in the sensor you must be able to
distinguish between valid alarms and nuisance alarms.
Fence structures
To ensure consistent detection, a sensor cable should be mounted on only one type of fence. All of
the fence panels should be similar in type, size and condition. Ensure that there are no loose
panels, fittings or metal parts that can move and cause nuisance alarms. A shake test in which you
grip the fence fabric in the middle of a panel and gently shake it back and forth with an increasing
motion will help identify any loose pieces. Listen for metal-on-metal contact and correct any
problems found. Verify that there are no washouts or depressions under the fence that could allow
an intruder access. Ensure that there is no vegetation or other objects that can make contact with
the fence in windy conditions.
Note Fences that are covered with vinyl privacy slats or other screening
material may not be suitable for the FlexZone sensor due to the
vibration dampening characteristics of the screening materials, and the
additional fence motion caused by wind. It may be necessary to remove
the screening material to ensure optimal FlexZone sensor performance.

Standard flexible fence types
chain-link welded-mesh
expanded metal
Chain-link fence
Chain-link fence is comprised of steel wires that are bent lengthwise into zig-zag patterns. The
zig-zag wires are vertically woven to form the characteristic diamond pattern. The fence fabric is
attached to fence posts approximately 3 m (10 ft.) apart. Tension wires are often used to stiffen the
fence fabric at the top, bottom and middle of the fence. Chain-link fences are available in different
heights and are sometimes vinyl coated.
Welded-mesh fences
A typical welded-mesh fence section consists of steel wire welded into a grid, with horizontal
spacing differing from vertical spacing. These fence sections are secured to fence posts and often
include top and bottom rails.
Expanded metal fences
Expanded metal mesh is typically comprised of a metal material with diamond shaped holes.
Metals can be expanded in a range of material thickness and to a broad choice of patterns to suit
specific applications. Expanded metal mesh is available with a variety of diamond size openings
and gauges that can be attached to a typical fence framework of round pipe and line rails.
Fence structures
Note High-security welded-mesh and expanded metal fences are comprised
of heavier gauge metal than the standard flexible fence types.
Therefore, these high-security fence types may have to be defined as
Rigid fences via the UCM. Begin testing with the Flexible fence setting
and use the Rigid fence setting only if adequate detection sensitivity
cannot be achieved at the Flexible fence setting.
Figure 1: Standard flexible fence types
FlexZone Product Guide Page 9
Fence structures
Rigid fence types
Note Rigid fence types do not conduct vibrations as well as flexible fence
types due to their materials and construction. FlexZone provides an
increased sensitivity setting for use with rigid fences. Senstar
recommends installing the FlexZone sensor on a limited length section
of the rigid fence to test and verify that the detection sensitivity meets
the security requirements before installing a full length perimeter.
Palisade fences
A typical palisade fence panel consists of metal pales fastened onto horizontal rails. These fence
sections are secured to fence posts which are securely anchored to, or into, the ground.
Figure 2: Rigid fence (palisade)
Climb-over deterrent hardware
Barbed wire
Senstar recommends using armored sensor cable on barbed wire. Armored cable is comprised of
FlexZone sensor cable inside flexible metal conduit. To protect both the fence and the barbed
wire, use armored cable on the barbed wire, and use sensor cable on the fence fabric. Install
armored cable on both sides of each outrigger and along the top of the fence (see Figure 3:
These configurations allow both sensor cables to be properly calibrated for the specific mounting
surface.
Barbed wire outriggers must be secure to prevent movement due to environmental conditions.
Install bracing wires between the outrigger supports to prevent the barbed wires from spreading
apart. Each barbed wire strand should be taut and tightly secured at each support. Any extension
arms or outriggers attached to post tops should have a tight press-fit or be spot-welded. Remove
or fasten any loose or rattling equipment.
Razor ribbon
Senstar recommends using armored cable on razor ribbon. The razor ribbon must be secured so
that it does not move in the wind. Use tensioning wires to secure the coil and to prevent the razor
ribbon from pulling apart if it is cut (see Figure 4:
).

Gates
Figure 3: Recommended cable installation on barbed wire
Figure 4: Razor ribbon
There are generally two types of gates used with fences, swinging gates and sliding gates. The
type of gate protection required is determined by:
• the type of gate
• the frequency of gate use
• when the sensor is active
• the type of ground beneath the gate
• the overall protection plan (the number of processors and sensor cables, and their location
relative to the gate in question)
FlexZone Product Guide Page 11
Buildings, walls and other structures
Gates should consist of fence fabric on a rigid frame that includes horizontal and vertical bracing.
• Firmly attach all gate hardware accessories (minimum free-play).
• Make sure that double gates have travel stops (rigid anchors).
• Prevent locking hardware from moving in the wind.
• Prevent sliding gate track hardware, supports, guides, etc., from rattling in the wind.
There are three ways to protect gates with the FlexZone sensor system:
• The wireless gate sensor (WGS),
• FlexZone sensor cable,
• An alternate sensor technology (e.g., a microwave sensor).
Gates that are not protected by the wireless gate sensor, or sensor cable, are bypassed via
software (see Figure 48:
side of the gate to the other, and the bypassing cable is set as non-detecting (it does not report
alarms). The sensor cable continues beyond the gate, and another technology is used to provide
protection in the area of the gate.
Occasionally, it is not possible to dig underground to continue the active coverage on the other
side of a gate. There are three standard solutions for this situation:
• Install the cable on the ground surface, under a secured, protective cable mat.
• Terminate the cable at the gate.
• Connect the cable across the gate using quick-disconnect connectors.
). The sensor cable is installed inside conduit, underground, from one
Buildings, walls and other structures
FlexZone can be used to detect intruders attempting to cut, saw, chisel, drill, or smash their way
through building walls, ceilings, roofs, floors, or stock cages. FlexZone sensor cable can be
attached to the structure using commercially available fasteners such as cable ties or nail-clamps
that ensure good contact between the sensor cable and the protected structure. The fastening
devices must not flatten or distort the sensor cable at the attachment points. Sensor cable can also
be installed inside metal conduit, which is attached to the protected surface. Due to the great
variation in building materials used in structures, Senstar recommends a trial installation on a
representative section of the structure before making the full installation.
Environment
For installations in environments which include hot sunny periods, install a sun shield to protect the
enclosure from direct sunlight, or install the enclosure in a shady area. Extra care must be taken at
sites that experience strong winds on a regular basis. The fence must be well-maintained to
prevent any metal to metal contact caused by the wind. All vegetation (weeds, brush, trees, etc.)
must be cleared from around the fence area. Vegetation must not touch or hang over the fence
fabric. Any objects that may contact the fence must also be removed from the perimeter. For sites
that experience snowfalls in the winter, the fence must be kept clear of accumulating snow. Snow
can dampen the vibrations that the FlexZone sensor uses to detect intrusions. Accumulated snow
can also serve as a bridging or tunneling aid for breaching the perimeter fences.
Note The ambient temperature, as measured inside the enclosure, must be
within the range of -40 to +70º C (-40 to +158º F).

FlexZone cable for at least 2 m onto the abutting fence.
Indicate the following on the site plan:
• The locations of existing structures (include fences, gates, buildings, roads, etc.). Verify that
mounting surfaces comply with established standards for installation and stability.
• The locations of obstacles including vegetation and trees.
• The locations for the FlexZone components:
• Sensor cable - indicate the cable layout and zone boundaries for each sensor cable.
• Non-detecting cable - indicate the layout if non-detecting cable is required (at the

Note A FlexZone perimeter with 1, 2, or 3 processors can be fully closed (all
sensor cables connected through splices). A FlexZone perimeter with 4
or more processors must be open at the ends (first and last sensor
cables must be terminated).
FlexZone sensor cable
There are two types of FlexZone sensor cable, standard and armored. Both Standard FlexZone
sensor cable and Armored FlexZone sensor cable come in 150 m (492 ft.) and 220 m (722 ft.)
lengths. Two lengths can be spliced together to provide up to a 300 m (984 ft.) long sensor cable.

• The full length of sensor cable must be mounted on the same type of surface.
• The maximum length of cable for each side of the processor is 300 meters (984 ft.).
• The smallest allowable bend radius for FlexZone sensor cable is 10 cm (4 in.).
• The smallest allowable bend radius for armored sensor cable is 15 cm (6 in.).
• Keep vertical drops of sensor cable to less than 1 m (3.3 ft.).
• The sensor cable should follow the ground contour to maintain a constant height above the
ground.

Note Senstar strongly recommends installing the sensor cable on the
secure side of the perimeter (the side of the fence opposite the
threat).
Cable length calculator (flexible fences)
Typically, fence coverage requires approximately 10% more cable than the linear fence length.
The following table provides a guideline for calculating the amount of sensor cable required for a
2.44 m (8 ft.) fence (in meters):
zone element required cable length (in meters)
start point + 1 m
service loops + 0.75 m X (linear cable length / 50)

Rigid fences
Service loops, zone demarcation loops and sensitivity loops are not recommended on rigid fences.
Therefore, the length of cable required on a rigid fence is approximately the length of the fence
plus 5% overage (for each cable pass).
Fence height recommendations
The following cable spacing recommendations will provide a high probability of detection on well
maintained fences (see Figure 8:
• For flexible fences up to 4.3 meters (14 ft.) tall - a single pass of sensor cable at 1/2 the fence
• For flexible fences greater than 4.3 m tall - a double pass of sensor cable at 1/3 and 2/3 the

fence height.
Note If the lower edge of the fence fabric is embedded in a concrete
footing, or below ground, an additional cable pass may be required
on the lower section of fence (a double pass at 1/3 and 2/3 fence
height).
Note If the fence framework includes an intermediate (middle) rail, it
may require a double cable pass, with one pass above the rail and
one pass below the rail.
Senstar recommends installing a single pass of cable 30 cm above
the middle rail on a small section of the fence (4 or 5 panels) and
then thoroughly testing the protected section to determine if a
single cable pass meets your detection requirements.
• For rigid fences (minimum recommended fence height 2 m, 6.5 ft.) - a double pass of sensor
cable along the top and bottom rails.
Non-detecting cable
For instances where the processor is located away from the protected fence, outdoor rated,
shielded 75 Ohm coaxial cable with a solid copper center conductor can be used as lead-in cable
(e.g., RG6). For cable bypasses along the perimeter, FlexZone sensor cable is used. The bypass
cable is set to inactive (Zone 0) in software and will not report sensor alarms. Non-detecting
FlexZone cable must be well secured to prevent any cable motion. The length of coaxial cable that
is used for lead-in must be deducted from the detecting cable length
(maximum cable length detecting plus non-detecting = 300 m, 984 ft.).
Figure 8: Cable pass recommendations
Page 16 FlexZone Product Guide
Perimeter layout guidelines
Fence corners and heavier gauge posts (flexible fences)
Corner posts and heavier gauge support posts tend to dampen the fence’s vibration transmission
characteristics. Therefore, use cable loops at corner posts and heavy gauge support posts, to
increase the sensitivity. Each sensitivity loop requires approximately 3 m (10 ft.) of sensor cable
(see Figure 23:
).
Zone demarcation loops (flexible fences)
Zone demarcation loops may be used at software defined zone boundaries for improved location
accuracy. It is possible that an alarm that occurs very close to a software defined zone boundary
could be reported in the adjacent zone (± 3 m). Zone demarcation loops add extra sensor cable at
zone boundaries to help ensure that an alarm is reported in the zone in which it occurs. Allot 3 m
(10 ft.) for each zone to adjacent zone boundary (see Figure 24:
). Rather than using extra cable
for zone demarcation loops, overlapping CCTV coverage can provide visual assessment to verify
alarms and alarm location. When setting up the camera views, ensure that there is at least 6 m
(20 ft.) of overlapping coverage at each zone boundary.
Service loops (flexible fences)
Service loops provide extra sensor cable along the fence to make cable repairs. Allot 75 cm
(30 in.) of cable each 50 m (164 ft.) for a service loop. Locate the U-shaped service loops at fence
posts (see Figure 25:
).
Drip loops (flexible fences)
Drip loops raise the connector above the sensor cable to prevent water from running along the
cable and accumulating in the enclosure. Drip loops also relieve strain resulting from temperature
changes that cause the cable to expand and contract. Form the drip loop by raising the connector
15 cm (6 in.) above the level of the cable run. Allot 50 cm (20 in.) of cable for each splice or
termination (see Figure 26:
).
Termination loops (flexible fences)
Termination loops provide extra sensor cable at the end of the protected section of the fence (at
the terminator) to make cable repairs or future sensor cable layout changes. The amount of cable
that can be used for a termination loop depends on the length of sensor cable (plus lead-in cable if
used) connected to the processor (side A or side B, maximum 300 m). Termination loops are
typically comprised of up to 5 coiled loops of sensor cable with a 60 cm (2 ft.) diameter.
Termination loops also include the length of 1 fence panel as the cable uses a double pass on the
final protected panel (see Figure 27:
).
Splice loops (flexible fences)
If there is extra sensor cable at the location of a cable splice, you can save the cable for cable
repairs or future sensor cable layout changes by forming a splice loop instead of cutting the cable
to length (see Figure 28:
). The maximum length of cable per side (300 m) cannot be exceeded,
but up to 10 m of cable can be coiled and attached to the fence at each side of a cable splice. A
10 m splice loop is comprised of 5 coiled loops of sensor cable with a 60 cm (2 ft.) diameter. Each
60 cm diameter coil of sensor cable contains approximately 2 m of cable.

Gate bypass
If there is a gate within a FlexZone sensor zone, you require a sufficient amount of inactive cable
to bypass the gate, even if the gate is protected by sensor cable. Secure the bypass cable and
bury it in PVC conduit. See Figure 48:
microwave system to provide security across the gate.
Armored cable
Armored cable is FlexZone sensor cable encased in a flexible metallic conduit. The armor protects
the sensor cable from damage and vandalism, as well as from the sun and weather. Steel cable
ties or wire ties are the recommended fasteners for armored cable. Armored cable is available in
lengths of 150 m (492 ft.). Two lengths can be spliced together to create a 300 m (984 ft.) cable.
Armored cable splices are enclosed inside metal condulet fittings (p/n G6KT0300).
Double pass coverage
For FlexZone installations which require double passes of sensor cable, you use both cable sides
of a processor to provide software zoning and precise target location. To accomplish this the
processor is located at one end and the two sensor cable sides run parallel for up to 300 m along
the fence in an upper and lower cable pass. The ends of the two sensor cables are terminated or
spliced together. To enable precise target location, the detection start points of both cables must
match, and both cables must be of equal length and have identical features (e.g., service loops,
sensitivity loops, etc.). Each FlexZone processor can provide double pass coverage for up to
300 m of cable.
for an example of a bypassed gate, which uses a
Note Senstar recommends that both cables for a double pass installation be
laid out side by side on the ground beside the fence and marked with
tape at 5 m (16 ft.) intervals for the full length of the cable. This will help
ensure that the cables are properly length matched which is essential
for detection sensitivity and location accuracy in a double pass
installation

For a multi-processor FlexZone installation with a double pass of sensor cable using software

number of requirements that must be observed. Figure 10:
illustrates a 1.8 km FlexZone
perimeter with six processors and a double pass of sensor cable.
• Each 48 VDC power supply can power to up to five processors over a maximum length of
1.5 km of sensor cable. The power supply must be connected to the central processor.
• The processors must be divided into blocks of two with network interface cards (NIC) carrying
the data between adjacent bocks (use multi-mode fiber optic NICs to isolate the sensor
blocks).
• The detection start points of each processor’s sensor cables must match, and both cables
must be of equal length and have identical features (e.g., service loops, sensitivity loops, zone
demarcation loops, etc.).
• Power flow, data flow and synchronization must be setup for each block of sensors via the
UCM.

The FlexZone enclosure is hinged and includes a lockable latch (requires a Customer-supplied
pad lock).
Power source and wiring
The FlexZone processor can operate on a wide range of input voltages (12 to 48 VDC). The power
supply, the number of processors, and the lengths of the power cable runs will determine the
gauge of the power cable wiring that is required. In locations where AC power may not be stable or
reliable, an uninterruptable power supply (UPS) should be used for primary power. Assume a
maximum power consumption of 2.5 W per FlexZone processor (with NIC).
Power over the sensor cables
A group of up to five FlexZone processors can share power via the connected sensor cables. In
this case, the central processor is connected to a 48 VDC power supply. The sensor cables from
the central processor are connected to the two adjacent processors (one on each side). The
processor connected to the power supply requires a stable, low resistance earth ground
connection, which also serves as the ground reference for the connected block of processors.
Power and data distribution is setup via the UCM. Figure 12:

Auxiliary device output power
Processors that are receiving power over the sensor cables can supply up to 2 W of power to an
auxiliary security device through T4, the power connector. The output power is at the same voltage
as the received power input via the sensor cables. The minimum required voltage to enable power
over the sensor cables is 38 VDC. Figure 76:

Power over Ethernet
Silver Network based processors using Ethernet communications have the option of using Power
over Ethernet (Figure 73:
option requires a PoE class 3 switch that is located within 100 m (328 ft.) of the processor, and
minimum Category 5 network cable. Power over Ethernet is supplied to the processor’s Network
Interface card (NIC) and the power output on the NIC is connected to the power input on the
processor. Each processor receiving PoE requires an earth ground connection.
Note Senstar recommends using a fully managed PoE switch, to supply
Grounding considerations
A stable low resistance earth ground connection is required by each processor that is connected
directly to a power supply. Use a short length of heavy gauge copper wire to connect the ground
lug on the bottom of the processor’s enclosure to an approved earth ground. Processors receiving
PoE also require a ground connection via the enclosure ground lug. Processor’s receiving power
over the sensor cables do not require a direct ground connection. These processors use the
ground of the processor that is connected to the network power supply as their ground reference.
Consult the local electrical code for grounding information.

Alarm data communications
Note Senstar recommends setting up a Silver Network, even when using
Local control mode. This enables remote calibration, maintenance
and diagnostic access to your FlexZone processors from a central
control facility.
There are two selectable control modes for the FlexZone processor’s inputs and outputs (I/O) local
control mode and remote control mode. You set the control mode in software, via the Universal
Configuration Module (UCM) which is a Windows-based software application. The default setting
is local control mode, in which the processor controls the on-board relays to signal alarm and
supervision conditions. In local control mode, the two Aux (auxiliary) inputs are self-test inputs to
the processor. In remote control mode, the alarm data is carried over the Silver Network to a host
security management system (SMS). Remote control mode enables the SMS to control the
processor’s relays as output points to operate other security equipment. The two Aux inputs
provide inputs to the host SMS for reporting the status of auxiliary devices. In both modes, you can
configure the processor’s input/output response according to your site-specific requirements.
• local control mode - hard-wired contact closure alarm data connections and self-test input
wiring connections are made between the processor and the annunciation equipment
(4 output relays, 2 self-test inputs) (the optional Relay Output card provides 4 additional
outputs for reporting alarm conditions)
• remote control mode - the alarm data communications are via the Silver Network - EIA-422
copper wire data paths or fiber optic cables connect one or two processors to the Network
Interface Unit (NIU), the remaining processors can be connected via EIA-422 wiring, fiber
optic cable, or data can be carried between processors via the sensor cables the 4 output
relays are available as output control points from the host system (the optional Relay Output
card provides 4 additional relays, which are also available as output control points), the 2
auxiliary device inputs are available for reporting the status of auxiliary equipment to the host
system (the optional dry contact input card provides 4 additional inputs, which are also
available for connecting auxiliary equipment to the host system)

Fail-safe relay operation
In the default configuration, the processor’s relays operate in fail-safe mode. During normal
operation, the relays latch in the non-alarm state. In the event of a total processor failure all relays

cable and a PoE switch (Silver Star)
Note You can use a combination of the above methods for powering and
data communications.
Note A Silver Network based processor can use local control mode to
operate its output relays and Aux inputs.
Relay Output Card
The relay output card (ROC) (P/N 00BA2500) includes four relays to supplement the four relays
available on the processor. In remote control mode, the host security management system
operates the ROC’s relays, as output control points, (e.g., to activate lights, doors, sirens, CCTV
equipment, etc.). You can configure the relays as latching (ON by command, OFF by command),
in flash mode (ON-OFF-ON-OFF, etc. by command, then OFF by command), or pulse mode (ON
for a period, then OFF). For flash and pulse modes, the Active/Inactive times are selectable.
Dry Contact Input Card
The dry contact input card (DRIC) (P/N 00BA2400) includes four inputs to supplement the two
inputs available on the processor. In remote control mode, the DRIC’s inputs connect auxiliary
devices to the host security management system (e.g., to report the status of other security
equipment such as a microwave or magnetic contact). The Filter Window parameter allows you to
set the time period for which an input must be active, before an event is reported.
Data over the sensor cables
A group of FlexZone processors can communicate via the connected sensor cables. In this case,
at least one processor requires a network interface card (NIC) to enable Silver Network
communications. The sensor cables from that processor are connected to the two adjacent
processors (one on each side). Processors that are using the sensor cables for data distribution
must be synchronized to prevent mutual interference.
To take advantage of the Silver Network’s redundant communications capability, two of the
connected processors require NICs and connections to a Network interface unit (NIU). In this way
network communications will travel in both directions over the sensor cables, so that a single break
in a sensor cable will not interrupt communications.
Page 22 FlexZone Product Guide
Processor synchronization
A group of FlexZone processors that are connected through the sensor cables must be
synchronized to prevent mutual interference. For a fully closed 2 or 3 processor perimeter, one
processor must be set as the Sync Master for the group. The Sync Master generates a
synchronization signal and transmits the signal through its A-side sensor cable. The next
processor receives the Sync signal through its B-side cable, synchronizes itself accordingly and
then sends the Sync signal on to the next connected processor (A-side to B-side). The Sync
Master will not accept a signal from another processor and always restarts the synchronization
process. To set a processor as the Sync Master connect the UCM to the processor and uncheck
the Accept Sync Signal check box.
Note Only one processor in a connected group can be set as the Sync
Master or mutual interference will occur.
For an open loop sensor configuration where at least one sensor cable ends with a terminator (not
connected to another sensor cable) the synchronization process is automatic and requires no
configuration changes. Each processor that is set to Accept Sync Signal will receive the Sync
signal through its B-side cable, synchronize itself accordingly and then send the Sync signal on to
the next connected processor. By default, the processor on the end of the perimeter that is
connected to the next processor through its A-side cable will generate the Sync signal that starts
the synchronization cycle.
Perimeter layout guidelines
Alarm monitoring
Alarm monitoring is site specific and depends on whether you are using relay outputs for alarm
reporting (Local control mode) or Silver Network based alarm reporting (Remote control mode).
Each processor has four user-configurable Form C relay outputs. In Local control mode, the four
relays are used to signal alarm and supervision conditions. For network based processors, alarm
data is carried over the network cables and the four relays are available as output control points
from the security management system (SMS).
NM Mode
The FlexZone processor can be configured to report alarm and supervision conditions through the
UltraLink modular I/O system. In NM Mode, the UltraLink I/O processor acts as the Network
Manager, providing alarm outputs for a connected network of up to eight Silver devices. In NM
Mode, the Silver devices do not require a connection to a PC running Silver Network Manager
software. Sensor alarms and supervision conditions are assigned to UltraLink I/O outputs (relay or
open collector). When an alarm occurs on a connected sensor, the corresponding UltraLink I/O
output is activated (see NM Mode
Cable connectors
The splice kit is used to join two FlexZone cables together, and to join lead-in cable to sensor
cable. The splice kit is also used to make cable repairs. The termination kit is used in situations
where a FlexZone sensor cable is not connected to another FlexZone sensor cable. In this case,
the termination kit is connected to the end of the sensor cable to enable processor supervision.
The cable connectors are mounted horizontally on the fence using two cable ties.

Note Senstar recommends limiting cable repair splices to one splice per
150 m (492 ft.) cable length.

High security installations
The FlexZone sensor can provide redundancy for high-security installations, providing certain
rules are followed. If these rules are followed, then the system will continue to provide perimeter
detection even if one processor fails, or a sensor cable is cut or if one power supply fails. With this
configuration, each 300 m of sensor cable is monitored simultaneously, by two processors.
Note If a sensor cable is cut, location accuracy may be diminished and an
increased system noise level (clutter) and NAR may occur. In the event
of a cut cable, repairs must be made as quickly as possible to return the
system to its full detection capabilities.
Note A fully redundant system requires that there be no single point of failure.
Therefore, the system requires two Network Interface Units, two
Network Manager PCs, two Security Management System PCs (NM
and SMS can reside on one PC) and two UPS systems.
High-security installation rules
• maximum sensor cable length for one side of a processor is 150 m (492 ft.) except terminated
open ends of perimeter (max 300 m)
• maximum length of sensor cable between 2 processors is 300 m (984 ft.)
• a minimum of two 48 VDC power supplies (depending on total number of processors)
• power supplies must be connected to processors on the ends of the perimeter
• two Silver Network connections to two Network Manager PCs at opposite ends of the loop,
OR, star network configuration setup using PoE with redundant switches

2 Installation
Installing the sensor cable
CAUTION FlexZone sensor cable must be conditioned before it is attached to
the fence.
CAUTION When installing FlexZone sensor cable during periods of freezing
weather (below 0º C, 32º F) extra care must be taken as the sensor
cable is less flexible, and the polypropylene cable ties can be prone to
failure.
Cable handling rules
The FlexZone sensor cable converts minute vibrations in the fence fabric into electrical signals.
Any damage to the cable from mishandling or poor installation practices will have a negative effect
on the system’s performance.
• DO NOT bend, twist, jerk, knot, or kink the sensor cable.
• DO NOT nick or scrape the sensor cable’s outer jacket.
• Avoid tight turns in the sensor cable, the minimum bend radius for FlexZone sensor cable is
10 cm (4 in.) and for armored FlexZone cable is 15 cm (6 in.).
• DO NOT place objects on the sensor cable or allow anyone to stand or walk on the cable.
• DO NOT allow the cable to fall off the side of the cable reel.
• DO NOT apply excessive tension to the sensor cable at any time.
• When using cable ties to attach the sensor cable to a fence, install the ties by hand and pull
them hand-tight until snug.
• DO NOT use mechanical tighteners to attach cable ties to a fence.
• DO NOT allow the sensor cable to be pinched between the fence and a fence post, or any
other object.
• Keep the ends of the sensor cable clean and dry. If water enters the loose tube it can cause
corrosion and potentially freeze in the winter, which will have a negative effect on sensitivity.
Note The number of cable passes required on a fence depends on the
height of the fence, the type of fence, and the required level of
security (see Fence height recommendations
FlexZone Product Guide Page 25
on page 16).

FlexZone sensor cable conditioning
Before installing FlexZone sensor cable, the cable must be conditioned. Prior to conditioning, there
may be excess center conductor in the cable, or the center conductor may be adhered to the cable
side walls after the manufacturing process. Conditioning frees the center conductor and
maximizes its movement, thereby providing the greatest sensitivity. Cable conditioning is best
done by two people and typically takes about 10 minutes for a 150 m sensor cable. FlexZone
cable conditioning can be done by a single person, but it can take significantly longer to complete
due to repeatedly walking back and forth.
Cable conditioning procedure (part 1 - cable preparation)
1. Dispense the sensor cable alongside the fence in a long straight line.
Note This procedure applies to both standard FlexZone sensor cable and
armored FlexZone sensor cable.
Note If site conditions prevent the cable from being laid out in a straight line,
minimize the number of turns and use as large a turn radius as
possible. Turns in the cable will require an increase in the amount of
pulling force needed to move the center conductor back and forth.
Note If the cable is moved to a more open area to be conditioned, move it
2. Carefully remove 30 cm (12 in.) of the black outer jacket, shield and clear tube to expose
30 cm of the center conductor at both ends of the cable. For armored cable, remove 45 cm
(18 in.) of the armor from each end of the cable, then expose 30 cm (12 in.) of center
conductor at each end.
carefully back to the installation location following the process. Avoid
using excessive pulling force and do not pull the cable around corners
or fence posts when it is repositioned.

3. Check the ends of the cable to verify that the center conductor is free to retract or extend
(i.e., the center conductor is straight and the cable end is not pinched, flattened, twisted, bent,
or distorted). If an end is damaged enough to prevent the free movement of the center
conductor, cut off the damaged section and re-strip the cable.
4. At both ends of the cable, tie a loop through a 2.5 cm (1 in.) piece of the black jacket, to
prevent the center conductor from retracting into the cable during the conditioning procedure.
Figure 15: Securing the center conductor
Cable conditioning procedure (part 2 - cable flossing)
Pull the cable by the black jacket to remove any slack and then use a “flossing” motion to pull the
center conductor back and forth to ensure the center conductor is floating freely over the full length
of the sensor cable.
Note Initially, there may be resistance as well as some “stretching” as the
center conductor is freed inside the cable (i.e., the center conductor
pulls out at one end but remains the same length at the other). Once the
center conductor moves back and forth easily so that pulling it out
15 cm (6 in.) at one end causes it to retract 15 cm at the other end, the
conditioning is complete.
Note You can hear the motion of the floating center conductor as it rattles
when you tap a properly conditioned sensor cable.
Note Maintain a firm grip and consistent pulling tension, and keep the sensor
cable taut and in-line during the cable conditioning procedure.
1. The first person begins by holding the cable by the black jacket with one hand and applying
light pulling tension to the center conductor with the other (see Figure 16:
).
The second person holds the cable by the black jacket and allows the center conductor to
move freely (no tension applied).
The first person stops pulling when they encounter an
increase in resistance or the center conductor can be pulled no further.

3. Continue this flossing motion back and forth until the center conductor moves easily with very
little resistance.
4. When the conditioning procedure is complete, release the tension on the center conductor,
and cut off any center conductor that was damaged during conditioning.
Note When conditioning is complete, the center conductor slides easily in both
directions, and it may extend an additional 15 to 30 cm out of the cable
jacket at both ends.
Note If the center conductor does not move back and forth easily (or at all)
during the flossing process, straighten any turns in the cable (relocate the
cable if necessary). Have one person grip the cable at one end and apply
light tension to the center conductor while the second person walks the
length of the cable from the other end shaking and tapping the cable.

Next, repeat the cable flossing procedure until the center conductor
moves freely and easily.

• Attach the sensor cable to the secure side of the fence (the side opposite the threat).
• Secure the cable to the fence so that it maintains a constant height above ground (i.e., if the
fence steps up a hill, the cable should also step up the hill).
• Use UV resistant polypropylene cable ties spaced 25 to 30 cm (10 to 12 in.) apart to attach the
sensor cable to the fence.
• Pull the cable ties until they are hand tight and the cable is snug to the fence.
• Attach the cable ties to the center of a link (one wire) NOT at the junction of two fence wires.
• Optionally, for increased security use two steel cable ties per fence panel in addition to the
polypropylene cable ties. Hand-tighten the steel cable tie on a fence wire adjacent to a
polypropylene cable tie to hold the cable snuggly against the fence without crushing or
distorting the sensor cable in any way. DO NOT use a mechanical tightening device.
• DO NOT attach the sensor cable to tension wires.
• Attach the sensor cable at least 30 cm (1 ft.) away from horizontal support bars and other
cables.
• For a single cable pass, attach the sensor wire to the middle of the fence.
• Avoid vertical drops greater than 1 m (3.3 ft.) when installing FlexZone sensor cable. Vertical
drops of 1 m or more can result in an area with excessive sensitivity, which may cause
nuisance alarms. Install vertical cable drops that are greater than 1 m with a minimum 15º
slope.
• Use armored sensor cable if the cable is being installed in an area where it may be prone to
damage from vandalism, equipment, or materials.
• Keep the ends of the cable clean and dry.
Installing the sensor cable
Note Galvanized fences occasionally have rough patches from the
galvanizing process. Avoid attaching the sensor cable at locations
where rough galvanizing can potentially damage the cable.
Note Tap the sensor cable occasionally as you attach it to the fence and
listen for the rattle of the floating center conductor to ensure the cable is
properly conditioned.
Installing cable ties
• Using UV resistant polypropylene cable ties, secure the cable to the fence fabric at the
midpoint of the chain-link. Install the cable ties by hand, tightening them enough to hold the
cable securely against the fence.
