SV SENSOR
QUICK INSTRUCTION MANUAL
INSTALLATION EXAMPLES
Height of fence ≥145 cm Height of fence ≥11 cm
Power source: completely passive
Attenuation: 9dB (equal to about 90m of fiber)
Protection rate: IP68 in metal box
Dimensions: 0x83x178mm
If the fence is higher than 145cm,
attach the SV sensor to the lower part of the fence
If the fence is higher than 11 cm,
attach the SV sensor to the upper part of the fence
Plastic fiber connectorization
The position of the sensor (on the fence) influences the sensitivity:
installing the SV sensor on the upper part of the fence will increase sensitivity
Pass the fiber (sewing) into the fence
to avoid intrusion by panel removal
The fiber can be fastened with cable ties
DO NOT TIGHTEN CABLE TIES TOO MUCH!
Intensive use of tight cable ties
increases fiber attenuation
reducing the maximum distance

INSTALLATION
1- Attach the SV sensor to the fence by using the brackets supplied
and connect plastic fiber to the LiteFENCE analyser
HOW TO SET LiteFENCE IN POWER METER MODE
Keep the DOWN button pressed while you switch-on the system: a dashed line appears on the display
HOW TO READ THE POWER METER DATA CORRECTLY
Plastic optical fiber is made of a polymeric material realized in such a way that it can lead the light inside and
guarantee the total reflection of the input signal, to transfer all the entering light to the exit.
However, physical and technical phenomenons occurr (ties, tension bolts, eye bolts) and cause power losses along
the fiber. That power loss is called attenuation.
Every meter of the installed plastic fiber introduces an attenuation resulting in: the more fiber you install, the
more attenuation you introduce, and the less optical power you will get at the end of the fiber.
Optical power is measured in dBm.
Example:
Maximum sensiti ity of Luceat systems is 30dB.
The distances mentioned take into account all common source of attenuation
(9dB e ery SV sensor and 0.1dB e ery meter of fiber)
Set LiteFENCE in the “power meter mode” so you'll
constantly monitor the attenuation of the fiber
during the installation of cable ties to identify
and avoid any increase of fiber attenuation
Each LiteFENCE tolerates a maximum attenuation of 3 dB,
equal to 2 SV sensors (equal to 9dB each)
and 1 m* of LiteWIRE plastic fiber (equal to 1 dB).
2 SV Sensors
1 LiteFENCE analyser

(*) reachable distance considering a correct installation with fiber attenuation <0,1 dB/m at 2 nm.
Sharp curves, cable ties or mechanical stress while placing the fiber can reduce the distance
N.B.: if you want to set the system in Power Meter mode when it is already switched-on, you need to RESET the system:
while you keep the OWN button pressed, press and release the RESET button, and then release
OWN button. After few seconds a dashed line will appear.
FIBER ENTRANCE
0 dBm = 0meters
FIBER EXIT

2-Supply the power to LiteFENCE SV device
3- Set the sensitivity
*These distances are aproximate and may change depending on fence type – we suggest making a real test on the fence
OK
1 - Thresholds: select fence type and height
(110 for rigid or > 110cm fence / 14 + for semirigid or > 14 cm fences
2 - Time Window: pre-alarm time before triggering the alarm (from 0.1 to 10 sec.)
OK
OK
3 - Input filter: high frequency filter (“OFF” only if you want to detect vibrations on very rigid fences)
Default setting of LiteFENCE is: height ≥145cm; pre-alarm time is 5£, filter is ON
In case of special en ironmental conditions or if you want to ha e different sensiti ity
performances you can reset these alues in the menu
Press the “DOWN” button to enter in the menu
Reset after every
change of sensitivity

What NOT to do
(these actions increase fiber attenuation)
1. do not walk on the fiber
2. do not make angles or sharp bendings (min. bending radius: 2 mm)
3. do not pull hard on the fiber
You can splice the cable mechanically
Each coupler reduces the max. distance of the system by about 2 m (2dB)
