1.Introduction
The Fiber SenSys FD348R is a rack mountable electro-optical Instrument that uses
optical fiber as a distributed sensor for detecting intruders attempting to breach a
perimeter. The Alarm Processing Unit (APU) can be tuned to disregard non-threatening
stimulus such as wind and animals; thus, reducing nuisance alarms. When an intruder is
detected, the APU sends out an alert via IP/XML Ethernet communication as well as
state changes in terminal contacts that can be used to switch on lights, cameras, sirens,
or to signal an alarm panel. IP/XML communication for direct network interface allows for
easy integration with any security solution.
The optical fiber-based system has been designed to be immune to the effects of
Electromagnetic Interference ( E M I), lightning, and radio frequency emissions. The
FD348R provides maximum effective intrusion detection through its inherent system
flexibility and advanced programmability.
Because the fiber optic sensors use laser light which is intrinsically inert, the FD348R
system can be installed safely at chemical or ammunition depots, or any location where
the use of electricity is a concern.
RS-232 communication allows for simple setup and calibration.
A key component of the FD348R is its fiber optic sensor cable; this uniquely-designed
cable, which is sensitive to movement, pressure, and vibration, can be routed along the
fabric of a fence to detect climbing and cutting. The detection of an intruder triggers an
alarm from the Alarm Processing Unit (APU).
Another key feature of the FD348R is its use of insensitive lead-in cables, allowing each
APU (up to 8 in one RK348 rack) to be mounted up to 20 kilometers (12.4 miles) away
from the protected zone. This feature lets the user install the APU in a location that is
close to power and communications as well as secure from weather.
The FD348R is designed to be installed in the RK348, a 19 inch rack-mount chassis that
houses and provides power for up to eight individual FD348R APUs. Each APU monitors
a separate zone, allowing for up to 8 separate zones to be independently monitored from
one rack mountable module.

5
Some of the intrusion threats the FD348R can be used to detect include:
Fence climbing (along both the fabric and post)
Fabric cutting
Crawling underneath a fence
Ladder assisted climbing of a fence
A single run of sensor cable can protect a zone up to 5 kilometers (16,400 feet/3.1
miles) in length.

7
Covers and panels
There are no user-serviceable parts inside the APU. To avoid personal injury, do not
remove any of the APU’s covers or panels. The product warranty is void if the factory
seal is broken. Do not operate the product unless the covers and panels are installed.
Inspection
The FD348R APU should be inspected for shipping damage. If any damage is found,
notify Fiber SenSys and file a claim with the carrier. Save the shipping container for
possible inspection by the carrier.
Laser radiation
The FD348R APU is a Class I laser product, as defined by IEC 60825-1 and CFR 21
subchapter J. A Class I laser product emits insufficient laser radiation to constitute a
hazard. However, avoid direct eye exposure to the output of this product or to the open
end of any optical-fiber cable connected to this product.
Fiber-handling precautions
Optical fibers are made of glass, and the ends of a broken fiber can be sharp and
may become lodged in the skin. Take appropriate glass-handling precautions.

8
FCC rules

3.The Sensing Fiber
The FD348R detects intruders by sensing small disturbances caused by vibrations
induced within a fiber optic sensor attached to the perimeter. The optical sensor is a thin
strand of multimode optical fiber. The fiber optic cable is installed in such a way that,
when intruders attempt to cross the perimeter, they create slight vibrations that disturb
the sensing fiber. These disturbances are then detected by the FD348R APU, which
generates the appropriate alarm(s).
Fiber Optic Sensing
When an optical fiber is exposed to vibration, the disturbance causes small asymmetric
changes in the fiber’s density. In turn, these changes in density cause measurable
changes in certain characteristics of laser radiation transmitted through the fiber. The
FD348R uses precision lasers and detectors, along with sophisticated digital signal
processing, to measure changes in the laser radiation. The processor analyzes the
incoming signals in order to determine whether they are caused by intruders, or
harmless nuisances, such as vibrating equipment. To learn more about fiber optics and
their use as sensors, refer to the application note on fiber optics titled: AN-SM-007 Fiber
Optics.
Sensor Cable
There are two types of sensor cable for the FD348R: SC-3 and SC-4.
SC-3 is distinguished by its dark brown protective jacket. This jacket ensures the cable
is resistant to weather , dirt, etc. although the cable is not outdoor rated and should be
contained within protective conduit.
• SC-3 (brown jacket) – 3 mm sensor cable used for perimeter applications.
Sensor cable comes in varying lengths , with up to 2000 meters (6500 feet) per spool.
• SC3-C (cable in conduit ) – 3 mm sensor cable within grey ½” UV rated conduit.
Cable in conduit should be purchased in premeasured zone lengths and reels can be up
to 800 meters.

10
SC-4 comes in a thicker green jacket and is outdoor rated. This cable can be attached
to the fence directly using nylon cable ties and does not need to be deployed within
protective conduit.
• SC-4 (green jacket) - 4 mm sensor cable used for perimeter applications.
Sensor cable comes in varying lengths with up to 2000 meters (6500 feet) per spool.
Insensitive Leads
The insensitive leads, so named because they are unaffected by vibrations, are single-
mode type optical cables. Fiber SenSys offers several single-mode cable configurations
to satisfy a wide range of system implementations. Like the sensor cable, the insensitive
leads are made of optical fiber that is immune to RF and EMI energy. The insensitive
leads are also weather resistant. These leads are used to transmit light from the APU to
the sensor cable mounted in the protection zone and back again.
Site Design and Installation
There are many different ways to use the FD348R system. The most common
installation is on chain link fence. For fence-mounted applications the fiber optic cable is
installed inside a flexible conduit which is then secured to the fence using stainless steel
wire ties. Other applications involve installing the optical cable inside the channels of
decorative metal fence or running the flexible conduit (with optical cable inside) along the
tops of concrete walls.
Ultimately, the method by which the FD348R system is deployed is up to the end user;
Fiber SenSys does not mandate one particular installation setup over another;
however, the general procedure for installing the FD348R system is:
1. Assess: Survey the site to be protected and record all information needed
for the site design phase.
2. Design: Create a strategy for protecting the site. This includes planning
the level of security, choosing the location of the APUs, provision of
electrical power, and planning cable routing.
3. Install: Proper deployment of the fiber optic sensor and correct installation
of the Fiber SenSys system.

11
To learn more about sensing fiber installations, refer to the application note on
installation: AN-ENG-027 Site Design and Installation for FD300 Series.
Connectors
To maintain a high signal-to-noise ratio, it is important that all connections within a given
fiber optic sensor (zone) be made by either fusion splicing or by physical-contact fiber
optic connectors (PC). It is helpful to test the optical loss of each zone. The insensitive
lead-in fibers plug directly into the APU and are always connected with an ST connector
(ST/PC). The insensitive leads are spliced, or coupled via ST/PC feedthrough connector,
to the sensing fibers.
Note: It is important that only clean optical connectors are inserted into the APU’s
optical inputs and outputs; dirty connectors can degrade the performance of the
APU or even cause irreversible damage. When leaving connectors unconnected
make sure they have protective caps installed on the ferrules. Caps protect the
ferrule from damage that might be caused by bumping the ferrule against a foreign
object. However, when caps are dirty they don’t protect (effectively) against
microscopic contamination. Consequently, be sure to clean all connectors prior to
insertion whether or not they have been capped. For more information on the care
and cleaning of fiber-optic connectors, refer to the application note on fiber optics:
AN-SM-007 Fiber Optics.

LED indicators. LED indicators for are found on the front panel of the module.
• " Fault " indicates a loss or significant degradation of returning optical power.
• " Event " indicates a disturbance or event has been detected in the sensor cable.
• " Alarm " indicates an alarm condition has occurred.
• " Power'' indicates the module is plugged in and receiving power.
• " Data'' indicates network activity (XML) and is green when the network is active.
When data is transmitted the LED will flash red.
Pressing the Test button (located below the LED indicators) causes the ALARM and
FAULT LEDs to light up and the corresponding relay contacts to change state.
On the back of the APU, accessible on the back of the RK348 when the APU is mounted
within the rack, there is an RJ45-style connector for TCP/IP Ethernet communication
with a security head-end or other annunciator/monitoring equipment.

5.SpectraView
Terminal emulation software or SpectraView tuning software is required to adjust the
tuning parameters of the APU. They run on a PC that is connected to the APU via the
RS-232 port on the front of the APU. Any terminal emulation software will work to
change APU parameters, but SpectraView is recommended for precision tuning.
SpectraView is a Windows-based software module that allows for the tuning of the
system so that it has maximum sensitivity when detecting intrusions with maximum
rejection for nuisance alarms. SpectraView also allows the user to monitor system
performance, and to record and analyze sensor data.
For instructions on how to change settings using a terminal, refer to Appendix B within
this manual.
Using SpectraView
With power off to the APU, connect one end of an RS-232 cable to the APU, and the
other end to the PC from which you will be launching SpectraView; then turn on power
to the APU.
Launch the SpectraView software by clicking on the icon pictured below, or navigate to
“All Programs | Fiber SenSys | SpectraView”:
