1.1 Scope
This manual is written to provide you with comprehensive knowledge of the detector.
This manual introduces you to the LaserSCANNER features, technical specifications and gives
an understanding of its components and their function. You will also find instructions on installing,
cabling and powering up the detector.
This manual is for anyone involved with the design, maintenance and purchasing of a VESDA
system. It is assumed that anyone using this manual has knowledge and the appropriate
certification from the local fire and electrical authorities.
1.2 Introduction to the LaserSCANNER
The LaserSCANNER can monitor and individually report on four sectors in the protected area.
The LaserSCANNER is an aspirating smoke detector providing very early warning of fire
conditions by drawing air samples through an air sampling pipe network. The detector chamber
can detect presence of smoke at very low concentrations. The embedded and PC software
complimenting the LaserSCANNER provides a wide range of user defined parameters and
reporting capabilities. The detector easily interfaces with fire warning and fire suppression
release systems, and can be easily integrated into a building management system.
Features of the LaserSCANNER
The LaserSCANNER features make it a versatile smoke detection product:
• Wide sensitivity range 0.005% obs/m to 20.0% obs/m (0.0015% obs/ft. to 6.24% obs/ft.)
• Each detector can cover an area of up to 2,000 m
2
(20,000 sq. ft.)
• Four programmable alarm thresholds (Alert, Action, Fire 1 and Fire 2)
• AutoLearn feature
• Four pipe inlets
• Individual pipe flow monitoring
• Scans individual sectors once smoke has been detected
• Replaceable air filter cartridge
• Option for inverted mounting
• Recessed mounting option
• Modular to meet site specific requirements
• Modular Display Module and LCD Programmer
• Programmable relays (option for 7 or 12 relays available)
• High efficiency aspirator
• Programmable General Purpose Input (GPI) to invoke operational modes
• PC programming and monitoring
• Multilingual displays
• Event Log for up to 18,000 events
1.3 Operation of the LaserSCANNER
An air sampling pipe network with sampling holes at appropriate spacing collects air samples
from a protected area.
An integrated Aspirator draws air in the sampling pipes through a Pipe Inlet Manifold (up to four
pipes can be connected to a LaserSCANNER detector). For further information on air sampling
pipe network please see the Pipe Network Design and Installation Manuals.
