Regional Regulatory Requirements and Notices
UL
For open area protection the fire alarm threshold (signal) that initiates an evacuation procedure via the Fire Alarm
Panel must not be set less sensitive than 0.625%/ft. The detector can send this signal via the Fire Alarm Panel
Output signal or the Pre-alarm output signal.
Through validation testing, Underwriters Laboratories Inc. has verified that VESDA ECO gas detectors, when
installed within the sample pipe network, present no significant effects on the smoke detection performance of
VESDA. The use of the ASPIRE2 calculation software is required to verify system design performance with all
devices included in the design.

1 Introduction
The VESDA VLP 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 VESDA VLP 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.
1.1 Features
The VESDA VLP features make it a versatile smoke detection product:
lEach detector can cover an area up to 2,000 m² (20,000 sq. ft.)
lWide sensitivity range
lFour programmable alarm thresholds
lAutoLearn feature
lFour pipe Inlets
lIndividual pipe flow monitoring
lReplaceable air filter cartridge
lOption for inverted mounting
lRecessed mounting option
lModular to meet site specific requirements
lModular Display Module and LCD Programmer
lSeven programmable relays
lHigh efficiency aspirator
lProgrammable general purpose Input
lPC capable programming and monitoring
lMultilingual displays
lEvent log for up to 18,000 events

2 Operation
An air sampling pipe network collects air samples from a protected area. The integrated aspirator draws air
into the sampling pipes through a pipe inlet manifold. Up to four pipes can be connected to a VESDA VLP
detector.1
Inside the VESDA VLP, a sample of air is passed into the laser detection chamber. Ultra-fine air filtration
provides very clean air to protect the optical surfaces inside the detector from contamination.
The detection chamber uses a stable Class 1 laser light source and carefully positioned sensors to achieve
the optimum response to a vast range of smoke types. 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 is
reported as an alert, action, fire 1 or fire 2 alarm depending upon the alarm thresholds.
Air is exhausted from the VESDA VLP and may be vented back into the protected zone.

2.1 VESDA VLP Configurations
The modular options available with a VESDA VLP are:
lFire and OK LEDs (FOK)
lLCD Programmer
lVESDA VLP Display Module
Figure 2-2: VLP-012 installed with LCD Programmer and Display Module
2.1.1 Display Module
The VESDA VLP 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 illuminate 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.

Figure 2-3: Display Module for VESDA VLP
OK LED
The OK LED stays illuminated during normal operation indicating the unit is functioning normally. When this
LED is off a warning beep sounds, indicating a Fault condition is active.

VESDA by Xtralis VESDAVLPProduct Guide
www.xtralis.com 7
Isolate LED
This LED is illuminated when the detector is Isolated and relays are de-activated disabling alarm outputs of
the detector. The display can be programmed to beep every 60 seconds.
Alarm Levels
lALERT: When illuminated 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.
lACTION: When illuminated 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.
lFIRE 1: When illuminated 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.
lFIRE 2: When illuminated 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:
lURGENT: A serious fault requiring immediate attention
lSYSTEM: A fault affecting the network to which the Display Module is connected
lZONE: A fault in the VESDA Zone monitored by the Display Module
lPOWER: A fault in the power supply if the GPI function is used
lNETWORK: A communications fault on VESDAnet
lAIRFLOW: Higher or lower than acceptable levels of air flow through the inlet pipe(s)
lFILTER: The air filter requires changing
Push Button Keys
These buttons enable various systems functions. These do not allow configuring the system. The buttons can
be disabled by the systems administrator.
lMode/Test (Dual Function): Selects modes on the numerical display - sensitivity, smoke level, or
zone number. When depressed for more than two seconds it performs a light test function.
lSilence: This button silences any alarm or fault warnings. The LEDs stop flashing to acknowledge a
fault or alarm condition.
lReset: Resets any latched alarms and faults on the detector. Any active alarms or faults are reported
again after the time delays have elapsed.
lIsolate: Isolates the detector from any external devices or systems (an isolate alarm will normally be
raised at the Fire Alarm Control Panel).
Note: It is normal practise to signal the Isolate condition to the Fire Control Panel using the Isolate relay.

VESDAVLPProduct Guide VESDA by Xtralis
8www.xtralis.com
Numerical Displays
lSensitivity: Shows the level of smoke that must be measured to illuminate the entire bar graph and
always corresponds with the Fire 1 alarm level.
lSmoke Level: Indicates the current level of smoke in the relevant VESDA Zone and is represented as
% obs/m or % obs/ft.
lZone Number: This is the VESDA Zone number assigned to the Display Module.
The Mode button is used to select the parameter to display in the numeric display. These values represent the
current readings for the corresponding parameters mentioned alongside the lit LED.
2.1.2 LCD Programmer
The VESDA LCD Programmer is used for configuring, commissioning and maintenance of the devices on
VESDAnet. It can replace either the center or the right plate of the front cover of the detector, or can be
mounted at a remote location. A hand-held model is also available. The hand-held model is connected to the
VESDAnet socket on the termination card of the detector. 1
