Product Overview
The LaserSCANNER detector (Model VLS-series) is
similar to the standard LaserPLUS detector, though
each LaserSCANNER detector also includes the
following elements:
 a valve mechanism in the inlet manifold
 software to control the airflow from
the four (4) VESDA sectors (pipes)
The software configuration enables one (1) VESDA
zone to be divided into four (4) separate sectors:
distinguishing between separate voids within a
room is an ideal example of this arrangement.
Operation
Each LaserSCANNER device draws air from all sectors
in use. If the smoke level reaches the Adaptive Scan
Threshold (AST), the LaserSCANNER quickly scans
each pipe to identify which pipe is carrying smoke.
If more than one (1) pipe is transporting smoke, the
sector with the highest smoke concentration is
designated as the First Alarm Sector (FAS).
Once Fast Scan is completed and the FAS identified,
the LaserSCANNER continues to closely monitor all
four (4) sectors (pipes) to monitor fire growth and
maintain full protection of the area.

There are four (4) Alarm levels: Alert, Action, Fire 1
and Fire 2 for each sector (pipe), and the sensitivity
for each level can be set to ensure optimum alarm
thresholds are applied for each sector.
LaserSCANNER Display
The LaserSCANNER display has a bar graph to
indicate the overall smoke level, alarm thresholds
and fault indication. The bar graph displays the
individual-sector smoke levels during the scanning
sequence. There is an extra light-emitting diode
(LED) to indicate that a ‘FAS’ has been identified, as
well as an extra function to the Silence button,
which allows for a manual scan to be initiated.
The LaserSCANNER display module can be mounted
into the LaserSCANNER front cover or remotely into
a 19-inch (48.3 cm) sub rack or a remote box.
Relay Options
The LaserSCANNER detector can be fitted with a
programmable seven or 12-relay termination card.
Relays may be mounted in a remote box
or in a 19-inch (48.3 cm) sub rack.

Operation ─ (continued)
VESDAnet
The status of the detector, as well as all Alarm, service
and Fault events, are transmitted to displays and
external systems via VESDAnet: VESDA’s fault-tolerant
communications protocol.
The VESDAnet loop, which provides a robust, bidirectional communication network between devices,
also allows continued operation during single-point
wiring failures. The VESDAnet loop also provides
system programming from a single location, and forms
the basis of the modular nature of the VESDA system.
AutoLearn
LaserSCANNER technology employs unique software to
ensure optimum operation in many environments.
AutoLearn monitors the ambient environment, and sets
the most appropriate Alarm-threshold commands (Alert,
Action, Fire 1 and Fire 2) during the commissioning
process. The aforementioned scenario allows
monitoring of the earliest possible warning for a
potential fire situation without triggering any nuisance
alarms.
Referencing
Environments that employ air-handling systems may be
affected by outside pollution entering the controlled
environment when “fresh-air make up” is added.
However, referencing by VESDA ensures any external
pollution does not interfere with the actual, valid smoke
level being detected in the protected space. The system
can safely compensate for this transient state, allowing
for continual operation − free from any nuisance alarms
(similarly with AutoLearn).
