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.
