These installation instructions provide essential information for installing VESDA-E VEU Aspirating Smoke Detectors in accordance with the system design. Additional installation and
product documentation is listed below in the Reference Documents section.
VESDA-E VEU Installation Instructions
System Components
The detector is shipped with the following components:
• 1 aspirating smoke detector
• 1 mounting bracket
• 1 mounting template for directly mounting the detector to the mounting surface
• 1 End of Line Resistor for the monitored GPI
• 1 installation instruction sheet
Prerequisites
• A completed system design.
• A 24V DC Power Supply, compliant with local codes and standards.
• Screws and inserts that are appropriate for the mounting suface.
•
Type A to Type B USB Interface Lead for initial configuration of the detector.
•
Labels as specified in the system design, e.g. Sampling Point labels
• Cable glands that are compliant with the IP rating of the detector.
•
Conduit, as specified in the system design.
• 0.2 mm
2
to 2.5 mm
2
(24 - 14 AWG) wiring for relays.
•
A PC or laptop installed with Xtralis VSC for initial configuration.
• Standard connection instructions for where the detectors are to be added to a corporate
network.
Standards Compliance
UL and ULC
For open area, open area high velocity and duct protection the fire alarm threshold (setting)
that initiates an evacuation signal must be set such that the sensitivity of each sampling
hole is more sensitive than 10%/m (3.2 %/ft) as determined by the ASPIRE software.
European Installations
The product must use a power supply conforming to EN54: Part 4.
The product is compliant with EN 54-20 sensitivity requirements provided the following
conditions are met:
• For a Class A detector, hole sensitivity must be better than 1.5% obscuration/m and
transport time less than 70 seconds
• For a Class B detector, hole sensitivity must be better than 3% obscuration/m and
transport time less than 90 seconds
• For a Class C detector, hole sensitivity must be better than 10% obscuration/m and
transport time less than 110 seconds
These limits should be verified using ASPIRE during the design of the sampling pipe
network.
The product is compliant with EN 54-20 flow monitoring requirements provided the
following conditions are met:
•
The minor low and minor high flow thresholds should be set at 85% and 115%
respectively
•
The flow through the detector predicted by ASPIRE must be greater than 20 L/m.

Installation Instructions
Notes
The VESDA-E detector can be mounted in an
upright or inverted position. Do not mount the
detector with a sideways orientation.
Ensure the mounting surface is flat as this allows an
air tight seal to be achieved between the sampling
pipe and the tapered air inlet pipes on the detector.
Refer to the detector Product Guide for information
on inverted mounting.
A
B
Ensure that there is sufficient clearance to mount
the detector, noting the location of air sampling
pipes and cable entry points. Due to the rigid nature
of the plastic pipe, installation must provide for
sufficient movement in all pipework (air inlet, air
exhaust and cable pipes) to allow pipe ends to be
easily fitted and removed.
•
A:
Minimum 50 mm (2 in.) below ceiling level.
•
B:
The detector can be mounted directly
against a wall or obstruction.
Attach the detector to the wall using the mounting bracket

• Position the mounting bracket (A) to allow sampling
pipes (B) and electrical conduit (C) to line up
horizontally with the alignment marks (D) and
vertically with the appropriate pipe depth line.
• 3/4 inch IPS (1.05 inch OD) sampling pipe should
vertically align with the top depth line (E).
• 25 mm OD sampling pipe should vertically
align with the bottom depth line (F).
• Hold the plate in position and mark positions
for 5 screw holes (G) on the mounting surface.
Remove the plate and drill holes. Insert plugs if
required.

• Align the mounting plate with the holes. Ensure
that the plate is level.
• Insert and tighten two screws (B) in the keyhole
slots (C) followed by three screws (D) in the
remaining slots.
• Use screws and inserts that are appropriate
for the mounting surface and the weight of the
detector.

• Align the mounting studs (A) on the rear of the
detector with the mounting stud slots on the
mounting bracket. Ensure that the center stud
(B) is in its slot.
• Slide the detector (C) down until the top of the
detector is flush with the top of the mounting
bracket.

• Open the door on the front of the detector by
inserting a thin screwdriver (A) into the hole at
bottom left of the door (B) and firmly pushing
perpendicular to the door surface to release the
door latch.
• Remove the tape covering the partially inserted
locking screw (C).
• Tighten the locking screw.
Attach the detector directly to the mounting surface
Use the provided mounting template. Refer to the Product Guide for further information.
Note:
Do not remove the mounting studs from the rear of the detector as they are also
used to hold internal components in place.
Inverted Mounting
Some system designs require that the detector be inverted. Directions for correcting the
orientation of the fascia for an inverted detector are available in the Product Guide.
