Summary
The versatility of the Fiber SenSys intrusion detection technology allows for a wide array of
implementation options. Laser Defender™is a quality solution for interiors using Lidar technology.
With a two-dimensional plane of coverage, the Laser Defender provides security by creating a
virtual wall or ceiling of protection. The purpose of this application note is to define how to
successfully plan, install, calibrate, and maintain the Laser Defender for the use of hangar and
bay door protection. The two products discussed in this note include the LD308SH™(30m
detection radius 180°-190°) and the LD204S™(20m x 20m at 95° coverage).
Introduction
The successful installation and operation of the Laser Defender are achieved by a thorough
understanding of the security needs of the site. Exercising careful planning before an installation
greatly increases durability and reliability throughout the life of the system. Advanced planning
should be followed with proper installation to ensure the sensor operates to its full potential. As
with any security system, periodic maintenance is necessary for long-lasting performance.
Fiber SenSys® recommends the following procedure for planning the installation of the Laser
Defender interior security sensor:
•Planning: Survey the site to be protected, observe all accessible areas of intrusions,
laser orientation (vertical and horizontal), wall or ceiling mount and record all
information needed for the site design phase.
•Design: Create a strategy for protecting the site. Choose the best fit detector, it’s
location, number of zones and masking of unwanted areas from detection should it
be necessary.
•Installation: Proper installation and alignment of the Laser Defender.
•Configuration: Settings for target size, location, area masking, and zone allocating.
•High probability of detection: Conduct a series of simulated intrusions per site
criteria while maintaining a low nuisance and false alarm rate (NAR/FAR). Simulated
intrusions may include:
oCrawling
oJumping
oWalking
oRunning
oRolling

Planning
The first step to a successful installation is performing a detailed site survey. The site survey
includes identifying the level of security, threat assessments, area drawings, site walk-through,
wire connections, and available mounting options. Analysis of the data obtained through this
process aids in the proper planning of zone layout and equipment selection.
Level of Security and Threat Assessment
During this stage, it is helpful to think from an intruder’s perspective. Try to imagine what weak
points of the building you would exploit and why.
•Given the nature of the facility, what is the maximum level of knowledge and experience
that potential intruders may possess?
•What are the most accessible entry points into the facility?
•What could cause a nuisance alarm?
oDusty environments
oMoving objects
oUnstable mounting
oSteam or spray from ventilation
Site Mapping, Walk-through, Mounting location
Before conducting a walk-through, it is helpful to obtain a detailed drawing or blueprint showing
the sites layout. This drawing should include ceiling heights, wall lengths, wire runs, and entry
points. During the walk-through, take note of any details not illustrated in the drawing, such as
fire extinguisher stations or other wall-mounted objects. These could affect the field-of-view of the
laser detector. Data collected duringthe threat assessment andwalk-through is used to determine
zone layout and equipment quantities.
Design
Based on the previous data, selecting the appropriate detector for the application is next. The
Laser Defender product line offers two sensing options.
•LD308SH - 30m radius detection coverage.
o19.2 to 30 VDC / 24 VAC.
o4 analog zone outputs / 1 master alarm output / 8 virtual zones for IP connection
oHorizontal Mode for ceiling protection / Vertical Mode for wall protection.

oPlease refer to PM-ENG-083 LD308SH Rev B installation manual for mounting
types
•LD204S - 20m x 20m at 95° detection coverage.
o12 to 24 VDC / PoE(+) compatible.
o3 programmable analog zones / 4 virtual zones for IP connection.
oMultiple mounting options for ceiling and wall protection. Please refer to PM-
ENG-084 LD-204S Rev B installation manual for mounting types.
What are the size requirements for detection? The 4 figures below illustrate the detectable target
size based on object color and reflectiveness. Note, detectable range depends on the reflectivity
of the target, its shape, and speed in which the object traverses through the detection area. For
military applications, install and test the system based on the black plate examples in Figure 1.
•Reflectivity of black plate: 10%
•Reflectivity of white plate: 90%

Installation
Between the planning stage and the installation date, there could be some downtime. During this
time, boxes and other peripheral devices could be installed or placed within the sensors field-of-
view. These changes to the site can create problems for the sensor’s placement and how the
sensor detects. Objects placed in the sensing area cause dead spots, also known as ‘shadowing’.
Cases like these should be avoided when possible and any movable objects removed from the
detectors view.
Before tuning can begin, laser alignment ensures proper detection in the desired area. Alignment
is best accomplished by using the LaserArea Checker (LAC-1). Using LEDand audible indication,
the LAC-1 sounds and flashes LEDs when in line with the laser’s detection pattern, as seen in the
figure below. This shows where the laser terminates and helps when adjusting the detector to its
proper sensing position.

Running Intrusion
Time is an important factor when detecting a fast runner. High sensitivity and angling of the laser
in a manner allows the detector more time to process fast intrusions.
Installing the laser facing straight down 270°, the LD308SH can detect a 5.5ft intruder running at
a speed of 6.71mph. Any faster potentially results in a missed alarm. Using the same intruder
height and high sensitivity, by angling the laser 30° would increase the running speed to 22mph.
Note:
Mounting height and detectable target size should be considered when choosing the mounting
location. Refer to page 6 of this app note for detectable target size.
Detection speed using
the LD204S™:
270° = 8.9mph
Angled 30° = 24.8mph

Configuration
To calibrate the sensor, first install the Laser Defender Manager Software (LDMS) on a laptop or
workstation. This software is provided as a free download with each hardware purchase and can
also be found at www.fibersensys.com/product/product-software. Connect the PC to the Laser
Defender via Ethernet port. Change the network settings of the PC to fit the same subnet as the
lasers default IP address.
(Example: IP address 192.168.0.100 and subnet mask 255.255.255.0 to communicate with the
main port)
LD308SH:
IP address - 192.168.0.126
Subnet Mask - 255.255.255.0
Default Gateway - 192.168.0.1
LD204S:
Main Port - 192.168.0.126
Subnet Mask - 255.255.255.0
Default Gateway - 192.168.0.1
Maintenance Port - 192.168.1.126
Subnet Mask - 255.255.255.0
The LD204S offers two Ethernet ports, main, and maintenance. The main port inside the base is
for constant connection to the LAN. This port supports PoE(+) and provides network alarm
reporting. The maintenance port is used for the initial setup and post-install maintenance. This
port is located near the laser window for easy access and avoids altering the laser alignment.
After launching the manager software, log in using the credentials below.

Password: FSI
Click on Edit Group/Detector Information to select the detector currently connected to the PC. For
this application note, we are using the LD204S as an example. In LDMS, confirm the PC’s IP
address fits the same subnet as the detector’s default IP address. Click Connect (F1) to establish
a connection to the Laser Defender.

If connection times out and abortsthe connecting process, follow the troubleshooting steps below.
•Confirm power.
•Confirm IP addresses are on the same subnet. (LD204S maintenance port uses a
different subnet).
•Check the physical connection
•IP conflict from other sensors. (Isolate sensor and try again)
•Contact Fiber SenSys technical support.
Settings
Once a connection to the Laser Defender has been made, the screen shows the detectors
information and the sensing area displayed in the graph. Before any changes to the detector can
be applied, an Area Set (F2) must be performed. The action of Area Set takes the perimeter edge
of the sensors field-of-view and learns the entire sensing area as the primary focus of detection.
The sensing area shows a gray outline around the perimeter.
Note: Any physical adjustments to the laser itself require another Area Set to relearn the laser’s
new position.
