Xtralis VESDA® VESDAnet Interface Card Product Guide
1 Scope
This guide describes the features of the VESDAnet Interface Card. It covers
the VESDAnet Interface Card’s functions and specifications, the installation,
commissioning and operating procedures. Also included in this guide are
overviews of how the VESDAnet Interface Card operates through VESDAnet
and with configuration tools such as the LCD Programmer and VSC.
Troubleshooting and maintenance of the VESDAnet Interface Card is also
covered.
2 Introduction to the VESDAnet Card
The VESDAnet Interface Card (also referred to as the VN Card) can be
installed into detectors, such as the Xtralis VESDA VLF, allowing
communication on the VESDAnet protocol. This will allow the detector to be
monitored for alarms and faults remotely. It will also allow configuration,
status monitoring and event log extraction via software tools on VESDAnet.
By interfacing a detector onto VESDAnet the features and options of the
remote display modules and referencing are supported.
The VESDAnet Interface Card has connectors that are similar to the ones
used on other Xtralis VESDA devices so it can easily be wired into
VESDAnet. It is not difficult to install and for most sites the only configuration
required is to set the VESDAnet address (zone) number and network time.

Wiring to VESDAnet
VESDAnet is a fault tolerant data communication network between VESDA
devices. VESDAnet cables are terminated at the VESDAnet A and B
Terminals on the VESDAnet Interface Card. Communications from another
VESDA device is brought into the VESDAnet Interface Card at one terminal
and looped out to another device on VESDAnet from the other terminal. It is
recommended that (Belden 9841 - 120 Ohm) twisted pair cables, or similar
cables be used.
Figure 4 - VESDAnet wiring with Shielded Twisted Pair-
maintain polarity
Figure 5 - VESDAnet closed loop wiring diagram with
Shielded Twisted Pair
Note: VESDAnet cabling can be wired A+ to A+, B+ to B+, or A+ to B+.
Also, A- to A-, B- to B-, or A- to B-. Shielded wire must be
terminated to the shielded connector.
Note: In the VESDAnet diagrams, the input wiring with circle to the
VESDAnet device communication ports, indicates shielded
twisted pair cable. This also highlights that the shield is
connected, at each cable end, to the “Sh” contact of the
VESDAnet communication port.

4 Using a Detector with the VESDAnet
Interface Card
Installing a VESDAnet Interface Card allows the Xtralis VESDA VLF to be
connected to VESDAnet. This will allow the VLF to be monitored for alarms
and faults remotely. It will also allow configuration, status monitoring and
event log extraction via software tools on VESDAnet.
The following sections detail the configuration of the VLF with a VESDAnet
Interface Card in various situations. It is highly recommended that VSC is
used to configure the VLF with VN Card. The advantages of the VSC over the
other software tools can be seen in the table below.
Table 2 - VESDAnet Interface Card configuration tool
comparison
Direct Serial connection to the VLF detector
You are able to directly connect to a VLF-VN by using a PC with VSC
software, and an RS-232 serial cable.
When you are logged into the detector via the direct connection at
Administrator level or above, configuration changes over VESDAnet will be
rejected. If the VESDAnet card is logged in to the detector at Administrator
level or above (due to configuration changes over VESDAnet) requests to log
in from a directly connected VSC will be rejected.

VESDAnet Interface Card Product Guide XtralisVESDA®
If the direct serial interface is being used to change settings, these changes
shall be shown and reported on the VESDAnet tools when the user logs out.
The VESDAnet tool shall be unable to change anything until the serial
interface has completed its configuration update.
Note: The installed card will influence the operation of the VLF. See
“VLF features disabled by VESDAnet Interface Card” on
page 11.
Guideline for using the VLF and VN Card with VESDAnet
Usernames and PINs
Configuration access to the VLF with VESDAnet can only be performed by
input of an username and password. In order for a user on the serial
connection to have the same password as when connecting via VESDAnet, it
is recommended to leave the default VESDAnet usernames (DST, USER &
ADM) in place. The password can be changed as usual via VESDAnet, using
VSC or the LCD Programmer.
The VESDAnet passwords for these usernames will then be copied to the VLF
detector by the VESDAnet Interface Card and can be used when logging in
using a serial connection to the VLF.
In a network of more than one detector, the lowest detector zone number shall
write its Password Identification Table (user names and passwords) to all
devices on the network. Ensure the lowest detector address number has
known Usernames and passwords before installation into a network of
devices.
Configuration Upon Installation:
Set the address number and time immediately upon installation or after
Restore Factory Defaults command is performed.
Address Number
The factory default VESDAnet Address is zero (0). The detector address must
be changed from 0 to the required address. The acceptable range is between
1 and 254.
Serial Number
The VESDAnet Interface Card has its own unique serial number. However,
only the ‘host’ detector serial number is reported by configuration tools.
Network Time
Set the time of all the network devices during installation and after issue of the
Restore Factory Defaults function.

www.xtralis.com 11
Xtralis VESDA® VESDAnet Interface Card Product Guide
In large networks of over 50 devices, the user may also need to change:
Preferred port
The VESDAnet transmission directions should be randomized. Either
randomize the wiring or randomize the preferred port setting. The factory
default preferred port on the VESDAnet Interface Card is Port A.
Minimum Interval between status events
The minimum interval between detector status messages being sent should
be set to 20 seconds. To set the minimum interval higher than 10 seconds,
VESDA System Configurator (VSC) software is required.
VLF features disabled by VESDAnet Interface Card
There are some features of the VLF detector that will not be available when
the VLF-VN is connected to VESDAnet, as VESDAnet does not support
those features. These are:
• Alert, Action, Fire 1 & Fire 2 verification delays for alarm set 2. These
delays are always set equal to the alarm set 1 delays
• The GPI (General Purpose Input) cannot be configured to alarm set 1,
or none
• Daylight saving functions are not available
• ‘Fixed’ selection of Day or Night smoke thresholds (time of day selection
is always used)
• PINs setup using a direct serial connection to the VLF is disabled
• The Major Flow Averaging Period is fixed at 60s (the same as VESDA
VLP detector products).
Configuring VLF and VESDAnet Interface Card
VESDA System Configurator (VSC) is recommended for configuring all
VESDA devices.
The VLF detector is identified as a VLF by VSC. It is displayed as a VLP (1
pipe) on original tools such as the LCD Programmer.
The VLF detector can either be configured using VSC via the direct serial
connection or via VESDAnet using VSC or with the LCD Programmer. VSC
Online help is available for more detailed information.
The following sections detail the difference between the configuration tools.

12 www.xtralis.com
VESDAnet Interface Card Product Guide XtralisVESDA®
Sampling pipe functionality
The VLF has a single sampling pipe as opposed to four on the VLP. The LCD
Programmer shall indicate the VLF pipe as the VLP Pipe 1.
This means that the only sampling pipe that can be enabled for use is Pipe 1.
Setting Aspirator Speed
The aspirator on the VLF-VN has a fixed speed and cannot be changed. The
LCD Programer has a function that allows VLP aspirator speed to be
changed. This command is visible with the VLF but no change can be made to
its speed.
Normalizing Airflow
The VLF detector airflow normalisation process is instantaneous compared to
the VLP, VLS and VLC detectors. The best way to check whether airflow
normalization was successful is to check the current flow for the Pipe. It
should read close to 100%.
Filter Replacement
When the filter in the VLF has been replaced the "Filter Old" fault needs to be
cleared. This can be done from VSC by sending the "Filter Insertion"
command with the option "New Filter" selected.
If using the LCD programmer, it will detect that the filter has been changed
and ask if the inserted filter is new or the original. Select the appropriate
option.

www.xtralis.com 13
Xtralis VESDA® VESDAnet Interface Card Product Guide
Configuring Relays
The VLF has three relays: Fault, Action and Fire 1. Using VSC the
configuration is shown below.
Figure 6 - VLF Relay config screen as viewed from VSC
Minimum Status Period
With the VLF detector, the minimum interval between detector status
messages being sent across the network can be set up to 20 seconds.
However the LCD Programmer software only supports a range of 2 to 10
seconds (the parameter is called ‘Detector Minimum Period’).
If the higher range is required then VSC must be used to configure.
If a higher range has been previously set with VSC and the user views the
setting using the LCD Programmer, the software will not allow the higher
setting unless the user exits the screen without applying any changes.
Flow Settings
When the LCD Programmer is used the VLF Minor Flow Averaging Period is
set using the Airflow Delay. The number entered is the averaging period and
not the delay to the airflow fault. The maximum value that can be entered is
60s compared to the 15 minutes of the standalone VLF (without interface
card installed).

VESDAnet Interface Card Product Guide XtralisVESDA®
Smoke Thresholds
With the LCD Programmer, the settings for choosing threshold levels based
on workdays and holiday periods cannot be used. Also, the cumulative alarms
setting cannot be used. The LCD Programmer enforces VLP threshold
ranges. VSC shall allow the VLF the full threshold range.
Table 3 - VLF Smoke Threshold limits from Differing Tools
General Purpose Input
The General Purpose Input on the VLF detector is similar to the VLP, but does
not have the Inverted Reset setting. When using the Programmer, you should
not select an Inverted Reset for the GPI function.
If you select the Mains OK setting on the Programmer, the VLF detector’s GPI
will be set to External mode.
Button Lockout
There are two specific front-panel buttons on the VLF, AutoLearn Smoke and
AutoLearn Flow which are not on the VLP. The lockout settings are not
available via the Programmer and can only be changed using VSC.
The button lockout function on the VLF locks out the function and not the
button. If a button has more than one function and only one function is locked
out the other function still operates.
Clearing the Event Log
Users are unable to clear the VLF detector’s event log.
