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 2,0 0 0 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

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.
LaserSCANNER Product Manual VESDA
2
Each pipe inlet in the manifold has a valve that can open or close the flow of air to the pipe. The scan function controls the opening and closing of the valves to detect the smoke carrying pipe. See The Scanning Function on page 3 for further information.
Some of the sampled air flows to the dual stage air filter. The first stage filtration removes dust and dirt from the sampled air and a small percentage of this air then flows to the laser detector chamber for detection smoke.
Any smoke detected in the laser detection chamber is signaled to the main processor card . If the presence of detected smoke is higher than the set thresholds it will be reported as an alert, action, fire 1 or fire 2 Alarm depending upon the set alarm thr esholds. The second stage filtration further filters the air to make it ultra clean air. The ultra clean air is used to protect the optical surfaces in the laser detector chamber.

The Scanning Function
The LaserSCANNER is designed to sample air from different sectors and to identify through a scanning process the sector reporting presence of smoke.
Scanning
During normal operation the scanner valves remain open and the LaserSCANNER draws air from all the pipes. When smoke is detected at a higher level than the scan threshold, for a period exceeding the configured scan delay (0 to 10 seconds), the detector performs a fa st scan. During the fast scan operation the LaserSCANNER samples air from e a ch sector (pipe) separately by controlling the scanner valves in the inlet manifold. The fast scan sequence for each pipe is approximately 4 seconds.
The sector reporting the highest level of smoke above the alert threshold is designated as the first alarm sector. The display modules assigned to the detector reports this by illuminating the first alarm and alert LEDs, and displaying the corresponding pipe number on the numeric screen.
Having identified the first alarm sector, the LaserSCANNER performs a slow scan using intelligent sequencing. The sector with the highest level of smoke (the first alarm sector) is scanned first. Each of the other sectors is scanned one at a time. Intelligent sequencing scans the first alarm sector in every alternate scan (e.g. if all the pipes are in use and pipe 1 corresponds to the first alarm sector then intelligent sequencing will scan Pipe
1,2,1,3,1,4,1,2......). The time spent sampling air in each sector depends upon the configured
sector time.
Adaptive scan threshold
The scan threshold is the configured threshold at which the detector co mmences scan ning once smoke has been detected at the threshold. The LaserSCANNER performs an adaptive scan process to automatically set scan thresholds at the optimized level. The adaptive scan threshold process is explained below:
Typically separate scan thresholds are set for day and night periods.
Scan thresholds are initially set to the lowest day or night alert threshold divided by the
number of pipes. If the threshold is set by AutoLEARN, the day or Night Alert Threshold is divided by 2.
The scan thresholds are then adapted automatically to eliminate unnecessary and
excessive scan cycles.
- Adapting the scan threshold u pwards - When the detected smok e level is lower than the configured Alert Threshold, the scan threshold increases upwards by 0.005% obs/m
0.0016% obs/ft.) with every fast scan cycle. It will continue to do so until the scan threshold is above the ambient smoke level or it equals the Alert Threshold. The scan threshold cannot exceed the Alert Threshold
- Adapting the scan threshold downward s - At every changeover time (from Day to night and from night to day) the detector determines if it is necessary to adapt the scan threshold downwards. Thus, if the scan threshold has been adjusted upwards, then in the following 24 hour period the detector begins a process of gradually lowering the scan threshold downwards to an optimum setting. The detector maintains a record of the maximum smoke readings measured in each day (or night) period. At the start of the next day (or night) period the scan threshold is automatically scaled downwards by calculating the difference between the current scan threshold and the ma xim um smo ke re adin g for the previous day (or night) period.
LaserSCANNER Product Manual VESDA

The Scanner Valve Test
The VESDA LaserSCANNER performs a scanner valve test when first powered up. Thereafter a valve test is performed every alternate T u esday at 12:00 hours. Duri ng the va lve test each val ve is individually closed and opened to ensure its proper functioning. Any improper functioning is reported as a fault (refer to the VESDA Tro ubleshooting Guide for fault descriptions and troubleshooting). It is possible to simulate a valve scan test by pressing the Silence/Scan button on the Display Module for two seconds, or selectin g th e sca n te st op tion un de r the dia g no stic s menu on the LCD programmer or the device menu on the PC software.
Sector Factor
By setting appropriate sector factors it is possible to set differen t alarm thr esholds for each o f the four sectors. The detector uses the sector factor to automatically calculate the alarm thresholds appropriate for each sector based on the configured alarm thresholds. These are multiplied by the sector factor to set the sector alarm thresholds.
Guidelines for setting sector factors:
Sector factors range between 0.5 and 2.0
Where more sensitive protection is desired for a sector (for example a critical server room where there are relatively more sampling holes and re str icted access), set the se cto r factor at less than 1.0
Where less sensitive protection is desired for a sector (for example where there is a risk th at a particular local process will generate nuisance alarms), set the sector factor at greater than 1.0
As a general rule, the difference between all pipes should not be greater than 1
Sector factors are generally optimized after a detector has been operational for a period and sufficient historical data has been g athered in the event log to assist the decision. However, if it is required to pre-determine the appropriate setting for sector factor the fo llowing methodo logy can be used:
Use ASPIRE Pipe Modelling Software to model the intended pipe layout
Determine the appropriate fire sensitivity required for each sector to achieve the desired hole sensitivity in each sector
Select an appropriate median setting for the Fire 1 thre shold to be configured in th e detector and calculate the appropriate sector factor which, when multiplied by the configured Fire 1 threshold, will give the desired fire sensitivity for each pipe
Record the desired Fire1 threshold setting and sector factor setting for configuration into the detector at commissioning.

Alarm Levels
ALERT: When lit this LED indicates that the smoke level is above the alert threshold. This means the detector has identified very early stages of a fire condition and/or that the smoke level in the area is above normal.
ACTION: When lit this LED indicates that the detected smoke level has passed the threshold value fixed for Action, but is not intended to initiate a general fire alarm response procedure.
FIRE 1: When lit this LED indicates that the detected smoke level is above the threshold value set to initiate a general fire alarm response procedure. This indicates a fire may be imminent or is in progress. When interfaced with a Fire Alarm Control Panel (FACP) it can generate an automatic fire alarm.
FIRE 2: When lit this LED indicates a fire is in progress. The detector can be interfaced with an FACP to activate automatic suppression systems and evacuation procedures.
Bar graph
The Bar graph is a 20 step indicator where each indicator represents an increase in the detected level of smoke, relative to the preset fire alarm level.
Threshold Indicators
The illuminated LEDs represent visual settings for ALERT , ACTION, and FIRE 1 alarm levels. The FIRE 1 indicator is always at the top.
Fault LEDs
The Fault LEDs illuminate to indicate: URGENT: A serious fault requiring immediate attention SYSTEM: A fault affecting the network to which the Display module is
connected ZONE: A fault in the VESDA Zone monitored by the Display module POWER: A fault in the power supply if the GPI function is used NETWORK: A communications fault on VESDAnet AIRFLOW: Higher or lower than acceptable levels of air flow through the inlet
pipe(s) FILTER: The air filter requires changing
