VESDA-E VES Installation Instructions
Prepare Detector:
Wiring, Pipe Inlet and Exhaust Ports
Remove the appropriate plugs for electrical cable installation (B), air sampling pipe inlet ports (A), and
exhaust port (C).
•
For VES detectors, where the system design requires less than four air sampling pipe inlet ports,
use ports 2 and 3 before using ports 1 and 4.
•
Do not remove the plugs from inlet ports that will not be used.
•
Ensure that pipes are clean and their ends are square and smooth.

•
Insert the inlet and exhaust pipes (if used) into the correct inlet ports (A) and exhaust port.
•
Exhaust pipe should be as short as possible.
•
Feed the electrical wiring connections through the cable entry ports.
•
Use the correct cable gland size to fit into the 26 mm (1”) cable entry port. Use correctly rated cable
glands to maintain the required IP rating.
Note:
Do not glue the inlet and exhaust pipe into the detector ports. The product warranty will be
void if the pipes are glued.
Wiring:
Power, Relays, GPIs, VESDAnet
Warning:
Always switch detector power OFF before plugging/unplugging electrical, relay or network
connections. Failure to do so may cause data corruption and/or component failure.
Avertissement :
Eteignez toujours détecteur avant de brancher/débrancher les relais électriques, ou de
connexions réseau. Au cas contraire vous pouver entraîner la défaillance corruption et/ou
élément de données.

Power and Relay Wiring
Power:
There are two sets of power terminals on the main board. Connect a 24 VDC power supply to the
PWR IN socket (B). If required, connect to another detector via the PWR OUT socket (A).
Relays:
The relays interface to the Fire Alarm Control Panel (FACP) to communicate faults, alarms and
disabled states. Relay contacts are rated 2 A @ 30 VDC, resistive. Connect as required by the system
design. Use electrical wire sizes from 0.2 mm² to 2.5 mm² (24 -14 AWG).
Warning:
Ensure that all wiring complies with manufacturer’s instructions and local and national fire
detection code requirements. Refer to the Codes and Standards Information for Air Sampling
Smoke Detection section of the detector product guide for further information on wiring
compliance.
Avertissement :
Verifier que toute les cables ont passé au nombres d’instructions du fabricant et locaux et au
feu national de securited’incendie sois exiger. Adresser aux codes informations sur les normes
et reglementations de detection de fume par prelevement d’air par le notice descriptive du
produit pour plus de renseignements au conformite du cablage.
Caution:
DO NOT LOOP WIRE UNDER TERMINALS WHEN WIRING DETECTORS. BREAK WIRE
RUNS TO PROVIDE SYSTEM SUPERVISION OF CONNECTIVITY.
Attention :
NE PAS RALIER LES CABLES TERMINAUX PENDANT LES CABLAGES DES FILS. POUR
TOUTES LES CONNECTIONS A RELAIS, INTERROMPRE LES FILS POUR PERMETTRE LA
SUPERVISION DU CABLAGE.
Note:
For information on wiring for other types of devices that may be required by the system
design, refer to the detector Product Guide and documentation accompanying the device.
Unmonitored GPI
The Unmonitored GPI senses a voltage level and is configurable to initiate a number of different actions.
“Reset” is the default setting.
Monitored GPI
The monitored GPI senses contact closure and is configurable to initiate the same actions as the
unmonitored GPI. “Mains OK” is the default setting. A closed contact signals GPI ON and open contact
signals GPI OFF.
A 10K end of line resistor is used to allow the detector to monitor for open circuit faults in the wiring from
the detector to the contact.

The diagram shows an example of the wiring for a
closed VESDAnet loop, which is the recommended
configuration. Remove the factory default A and B
links from the VESDAnet sockets (C and D) prior
to connecting the detector to the VESDAnet. It is
recommended that 120 Ohm twisted pair cables
(e.g. Belden 9841) be used for including the
devices in the network, with a maximum length
between devices of 1.2 km The polarity of the data
wires must be maintained throughout the network.

The diagram below shows the factory default wiring for VESDAnet sockets (C and D)
as required for a detector that is not connected to a VESDAnet.
•
Leave as is, or replace if it has been removed.
Ground Fault Detection
In order for VESDAnet ground fault detection to be active, connect the Chassis Ground Terminal (Q) to the
building ground and insert a jumper on the Ground Fault Monitoring Jumper terminals (V).
Communications
•
USB:
The USB port (S) is used for initial configuration and local maintenance or servicing of the
detector using a PC or laptop with Xtralis VSC software. Install Xtralis VSC prior to connecting the
detector to the computer. This ensures that the required USB drivers are present.
•
Ethernet:
The Ethernet port (R) is used for permanent network connection to the detector, and
provides a gateway to other devices on the VESDAnet network. Ethernet connection settings and
detector access password must be configured using a USB connection prior to use.
•
WiFi:
The WiFi provides a network connection to the detector and provides a gateway to other devices
on the VESDAnet network. WiFi connection settings and detector access password must be configured
using a USB connection prior to use.
Sampling Pipe Network
Complete the pipe network installation in accordance with the system design. Refer to the detector Product
Guide and the VESDA Pipe Network Installation Guide for general information regarding pipe network
installation.
•
Ensure that the exhaust is open, the pipes are clear and all sampling holes have been drilled.
Power Up
Connect 24 VDC power to the Power In terminals (B). Close front door.
Configuration
For initial configuration, use a USB connection and the Xtralis VSC software.
•
For networked detectors, set the IP address and subnet mask according to standard building
instructions.
•
Set the Pipes in Use value in the Airflow configuration options.
•
Set the aspirator RPM to the value specified in the system design.
•
Let the detector run for approximately 2 minutes and confirm that the pipe raw flow rates (L/min) match
the ASPIRE predictions using Xtralis VSC.
•
Normalize the airflow. This takes approximately 10 minutes, after which the pipe flow rates (%) should
be close to 100%.
•
Reset the detector. It should now be running without faults.
Commissioning
•
Carry out a smoke test. Refer to the product guide for further information.

Note:
To remove the pipe inlet and cable entry port
plugs, place a large screwdriver in the large
slot and twist, or use a small screwdriver in
the side slots to lever the plug out.
