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:
o Crawling
o Jumping
o Walking
o Running
o Rolling
