We strongly recommend that this document is read in conjunction with the appropriate local codes and standards for smoke detection and electrical
connections. This document contains generic product information and some sections may not comply with all local codes and standards. In these cases,
the local codes and standards must take precedence. The information below was correct at time of printing but may now be out of date, check with your
local codes, standards and listings for the current restrictions.
FCC Compliance Statement
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television
reception, the user is encouraged to try to correct the interference by one or more of the following measures; re-orientate or relocate the receiving antenna,
increase the separation between the equipment and receiver, connect the equipment to a power outlet which is on a different power circuit to the receiver
or consult the dealer or an experienced radio/television technician for help.
FDA
This VESDA product incorporates a laser device and is classified as a Class 1 laser product that complies with FDA regulations 21 CFR 1040.10. The laser

1 Introduction
Scope of this Guide
This guide is intended for installation technicians to be able to install, perform basic power and
preliminary device checks for the VLC detector. It does not cover information for commissioning. All
VESDA equipment is to be commissioned by personnel who have attended a VESDA accreditation
course.
Use the checklist in Section 9 to verify that the installation has been correctly completed. Fill out the
details in the checklist sheet for the site and submit it to the appropriate personnel.
CAUTION
* The Detector must only be installed by VESDA accredited personnel.
* The performance of the system depends on the pipe network that was designed for the site.
Any alteration to the pipe network may alter the performance of the system. The ASPIRE2™
design tool is to be used to verify the suitability of any pipe network design and subsequent
alterations. ASPIRE2™ is available from your distributor.
* The IP rating for the VLC is IP 30. This rating indicates the device is not to be installed
where there is the possibility of any water or liquid falling onto the device.

6.1 Check Procedure Before Installation
(a) Do not install your VLC if there are any signs of shipping damage to the product. Inform your
distributor if there is any damage.
(b) Check the model of the VLC is correct as per the design specifications for the site. Refer to the
model number located on the bottom of the detector enclosure.
(c) Identify the location where the detector is to be mounted. The VLC can be mounted on a wall or a
suitable secure surface. There are two allowable mounting positions (see Figure 3) for the VLC:
•Mounting the device with the air inlet pipe on the top of the box and with the air exhaust pipe
at the bottom. (Normal Orientation)
•Mounting the device with the air inlet pipe at the bottom of the box and with the air exhaust
pipe on the top. (Inverted Orientation)
(d) Verify that the selected mounting location is suitable to fit the detector by test fitting the VLC onto
the actual mounting position. Ensure there is 150mm (6in) of clear space around the air inlet pipe
and cable entry points to allow for pipe and conduit entry.
(e) Verify that the cable entry points and the sampling air pipes are at the correct locations.
(f) Determine the type of fasteners required to attach the mounting bracket onto the mounting
surface. The size of the screw holes on the mounting plate is 8mm (1/3in).

6.2 Removal of Front Cover
(a) Unscrew the two Philips head screws located on the left and right hand sides of the front cover.
(b) Remove the cover. The front cover is held to the main enclosure with a plastic tie. There is a
cable loom labelled LED CARD that connects the termination card in the enclosure to the LED
card located behind the front cover. If you need to separate the front cover from the main
enclosure perform steps (c) to (d), otherwise go to step 6.3.
(c) Remove the LED CARD cable connector from its socket on the termination card.
(d) Twist the plastic tie by 90 degrees on the cover side and slip the tie out through the slot.
Figure 4VLC with Front Cover removed. (Normal Orientation).
6.3 Removal of Plastic Plugs for Cable Entry
(a) Determine the cable entry holes to be used. Refer to Figure 4.
(b) Use your thumb to push out the hole plugs from inside the enclosure.

6.4 Securing the Mounting Bracket
Warning Make sure that there are no electrical wires or plumbing behind the mounting
position before drilling. Ensure the mounting position is flat.
(a) Place the mounting bracket onto the surface and mark out the two mounting screw holes. Refer to
Figure 5 for dimensions. Use a spirit level to ensure the bracket is level.
(b) Use the appropriate fasteners to suit the mounting surface. Secure the bracket to the surface.

6.5 Attaching the Detector onto the Bracket
(a) Determine the required orientation for the VLC.
(b) Mount the detector onto the bracket by placing the four rectangular slots located on the rear of the
detector onto the four bracket tabs. Refer to Figure 6.
(c) Slide the device downwards until it locks onto the tabs and screw in the anti tamper screw. Refer
to Figure 7 for screw location.
(d) Check the unit does not slide off its bracket.

Figure 7 Location of Anti Tamper Screw and other Components inside the Enclosure
6.6 Connecting the Air Sampling Pipe
The air inlet port is designed to fit a standard pipe of 25mm (1in) OD. A tapering of the air inlet port
prevents the pipe from being inserted beyond 15mm (5/8in).
Note Where it is common practice to use ¾ inch pipe which has a 1 1/16 inch OD, a suitable
adaptor should be used to connect the pipe to the inlet manifold. Such an adaptor is
supplied with the VLC in the appropriate territories.
a) De-burr and square off the end of the sampling air pipe. Ensure the pipe is free from swarf.
b) Remove the plugs from the inlet and exhaust ports.
c) Insert the pipe into the inlet port ensuring a firm fit. DO NOT glue this connection.
d) Pipe the exhaust when necessary.
Caution DO NOT GLUE THE AIR INLET AND EXHAUST PIPE CONNECTION – THIS ACTION
WILL VOID YOUR WARRANTY
Glued connections makes disconnecting the air sampling pipe from the VLC for
maintenance extremely difficult and will result in damage to the equipment.

6.7 Cabling Using Glands and Conduits
6.7.1 Using Glands
(a) If using cable glands, use the correct gland size to fit the 25mm (1in) ∅cable entry hole.
(b) Run the wires through the glands and into the VLC enclosure. Use your local codes and electrical
standards for cabling.
6.7.2 Using Conduits
(a) Terminate the conduits at the cable entry holes on the sides of the box using the appropriate
conduit connectors.
(b) Run the wires through the conduits and into the VLC enclosure. Use your local codes and
electrical standards for cabling.
