VESDA VLC-500 Installation Instructions

VESDA VLC-500 and VLC-505 Installation Instructions
These installation instructions provide essential information for installing VESDA VLC 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 installation instruction sheet
• 1 product guide
Prerequisites
• A completed system design documents
• A 24V DC Power Supply, compliant with local codes and standards
• Screws and inserts that are appropriate for the mounting suface
• RS-232 9-way serial cable for VLC-500, sliding windows HLI (VHX - 0200) for
VLC-505
• Labels as specified in the system design
• Cable glands that are compliant with the IP rating of the detector
• Conduit, as specified in the system design
• 0.2 mm
2 2
to 2.5 mm (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
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 ASPIRE calculation
software is required to verify system design performance with all devices included in the
design.
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 60 seconds
• For a Class B detector, hole sensitivity must be better than 4.5% 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 120 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 should be in the range 20 to 65
lpm
Power Consumption (18 - 30 VDC Supply)
Power Consumption 5.4 W during normal operation, 5.9 W with alarm on

Environmental Requirements

• Temperature
• Ambient:
0°C to 39°C (32°F to 103°F)
• Sampled Air: -20°C to 60°C (-4°F to 140°F)
• Tested to:
-10°C to 55°C (14°F to 131°F)
UL : 0° to 38°C (32° F to 100° 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.

Installation Instructions

Notes
Secure the mounting bracket to the mounting surface
Install the detector
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
Prepare Detector:
Wiring, Pipe Inlet and Exhaust Ports
Remove the appropriate plugs for electrical cable installation (J), air sampling pipe inlet
port (K), and exhaust port (F).
• 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 (K) and
exhaust port (F).
• 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.
The VESDA 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 pipe 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.
• A: Minimum 50 mm (2 in.) below ceiling level.
• B: The detector can be mounted directly
against a wall or obstruction.
• The mounting bracket for the VESDA VLC is
always mounted in the UP direction. It is clearly
marked with the word "UP" and an upward
pointing arrow.
• Secure the mounting bracket to the surface
using appropriate fasteners, ensuring that the
bracket is horizontally straight and sits flush on
the surface.
• Determine the ports for cable entry. Press out the
tabs for the cable entry, air inlet and air exhaust
ports.
• VESDA VLC detector.
• Remove the front cover and if necessary
separate it from the enclosure box. The back
of the enclosure box is slotted over the four
mounting bracket tabs. Slide the detector
downwards until it slides onto the tabs.
• Screw in the anti-tamper screw. Check to confirm
that the detector does not slide off the mounting
bracket.
