This manual is written to provide you with comprehensive knowledge of the detector.
This manual introduces you to the Xtralis VESDA VLS 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 an Xtralis
VESDA system. It is assumed that anyone using this manual has knowledge and the appropriate
certification from the local fire and electrical authorities.
2 Introduction to the VLS
The VLS can monitor and individually report on four sectors in the protected area.
The VLS 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 VLS 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 VLS
The VLS 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 m2(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

3 Operation of the VLS
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 VLS detector). For further information on air sampling pipe network
please see the Pipe Network Design and Installation Manuals.
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 6 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.

Xtralis VESDA® Xtralis VESDA VLS Product Guide
www.xtralis.com 5
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 thresholds. 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 VLS 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 VLS 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 fast scan. During the fast
scan operation the VLS samples air from each 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 VLS 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 commences scanning once
smoke has been detected at the threshold. The VLS 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 upwards - When the detected smoke 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 downwards - 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 maximum smoke reading for the
previous day (or night) period.
The Scanner Valve Test
The VLS performs a scanner valve test when first powered up. Thereafter a valve test is
performed every alternate Tuesday at 12:00 hours. During the valve test each valve is
individually closed and opened to ensure its proper functioning. Any improper functioning is
reported as a fault (refer to the Xtralis VESDA Troubleshooting 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 selecting the scan test option under the diagnostics
menu on the LCD programmer or the device menu on the PC software.

Xtralis VESDA® Xtralis VESDA VLS Product Guide
www.xtralis.com 7
Sector Factor
By setting appropriate sector factors it is possible to set different alarm thresholds for each of 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 restricted access), set the sector factor
at less than 1.0
• Where less sensitive protection is desired for a sector (for example where there is a risk that
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 gathered in the event log to assist the decision. However, if it is
required to pre-determine the appropriate setting for sector factor the following methodology can
be used:
• Use ASPIRE2 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 threshold to be configured in the 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.
VLS Configurations:
One or more devices can be integrated with the VLS detector. These are normally configured at
the factory prior to shipping, but can also be installed at a later time. The standard VLS comes
with 7 relays or in an optional 12 relay version. The modules that can be integrated are:
• Display Module
• LCD Programmer Module
• Fire and OK LEDs (FOK) Module

Display Module
The VLS Display Module is mounted either on the detector front cover or at a remote location in
a remote mounting box or a 19” subrack. It provides a visual representation of the smoke levels
and the four alarm stages for the assigned detector. An array of fault LEDs light up in different
configurations to report Urgent, Minor, Zone and System faults. Up to 20 Display Modules can be
assigned to one detector, however the Display Module can be configured to report the status of
only one detector at a time.

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
