VESDA -E VEP Installation Instructions

VESDA-E VEP Installation Instructions
These installation instructions provide essential information for installing VESDA-E VEP Aspirating Smoke Detectors in accordance with the system design. Additional installation and product documentation is listed
below in the Reference Documents section.
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 to 2.5 mm (24 - 14 AWG) wiring for relays.
2 2
• 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
EN 54-20
The product must use a power source conforming to EN 54-4 and EN60950-1 Section 2.5.
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 60 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 8% 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.

Environmental Requirements
• Temperature
• Ambient: 0°C to 39°C (32°F to 102°F)
Sampled Air: -20°C to 60°C (-4°F to 140°F)
•
• Tested to: -20°C to 55°C (-4°F to 131°F)
UL: -20°C to 50°C (-4°F to 122°F)
• Humidity: 10-95% RH, non-condensing
Note:
Please consult your Xtralis representative for information on operation outside these
parameters or where sampled air is continually above 0.05% obs/m (0.015% obs/ft) under
normal operating conditions.

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.
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.
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.
B
• A: Minimum 50 mm (2 in.) below ceiling level.
B: The detector can be mounted directly against a
•
wall or obstruction.
• Position the mounting bracket (A) to allow sampling pipes
(B) and electrical conduit (C) to line up horizontally with the
B
alignment marks (D) and vertically with the appropriate pipe
depth line.
E
F • 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).

• 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.
