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:
• Reorientate 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 from which the
receiver is connected
• Consult the dealer or an experienced radio/television technician for help

1. Introduction
Scope of this Manual
This manual is intended for installation technicians to be able to install, perform basic power and
preliminary device checks for the LaserSCANNER 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 designed for the site.
Any alteration to the pipe network may alter the performance of the system. The
ASPIRE™ design tool is to be used to verify the suitability of any pipe network design
and subsequent alterations. ASPIRE™ is available from your distributor or local
Vision office.
• The IP rating for the LaserSCANNER 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.
WARNING
• It is strongly recommended that the mounting bracket be used during installation.
• The chassis assembly and Central Processor Card should NOT TO BE REMOVED or
disassembled during installation.
• Follow the installation procedure outlined in this manual.

6. Installation
6.1 Check Procedure Before Installation
(a) Do not install your LaserSCANNER 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 LaserSCANNER is correct as per the design specifications for the
site. Refer to the model number located on the product and approvals label attached at the
bottom of the detector.
(c) Identify the location where the detector is to be mounted. The LaserSCANNER can be
mounted on a wall or a suitable secure surface. There are two allowable mounting positions
for the LaserSCANNER as shown in Figure 3.
• Normal Orientation: Mounting the detector with the inlet air ports on the top right
hand side of the box and the exhaust air port at the bottom.
• Inverted Orientation: Mounting the detector with the inlet air ports at the bottom
left hand side of the box and the exhaust air port on the top.
(d) Verify that the selected mounting location is suitable to fit the detector by test fitting the
LaserSCANNER onto the actual mounting position or use the drilling template supplied with
this manual. Ensure there is 150mm of clear space around the air inlet, exhaust and cable
entry ports to allow for pipe and cable entry.
(e) Verify that the cable entry points and the sampling air pipes are at its correct locations.
(f) Determine the type of fasteners required for attaching the mounting bracket onto the
mounting surface. The size of the mounting holes on the mounting bracket is 6mm
(15/64in).
Note: For LaserSCANNER detectors mounted in the Inverted Orientation position, the
display and/or programmer modules have to be rotated 180°. Refer to Section 6.4
for procedure to rotate the modules. The position of the Programmer and Display
modules can be interchanged.
