Certain building and processes
demand the earliest possible warning of a fire.
The reliance
that reliance that businesses today place on their computer
and telephone installations means that response must be rapid
and dependable.
It is in such instances that the unique VESDA
LaserPLUS a rating smoke detection system plays an invaluble
role.
Its extraordinarily high level of sensitivity detects
the first microscopic evidence of fire at the pre-combustion
stage, long before visible smoke or flames are present.
Early detection
Communication centres,
computer suites and call centres, particularly those with
high ceilings or incorporating air conditioning, are
especially at risk. Likewise archives, museums and heritage
buildings all share zero tolerance to delay of any kind when
it comes to fire safety.
In such cases, conventional smoke detectors are too
insensitive and can be easily rendered ineffective by the
filters in air conditioning units, the introduction of fresh
make-up air and high airflows. Often, the time taken for
smoke to achieve sufficient density to activate even the
most advanced-design conventional high-level sensor may be
too long.

works
Air is continuously drawn
into the piping network by an internal a Gielle rator. A
sample of this air is transported through the filter to the
detection chamber. Using advanced laser technology, the
detector analyses the air sample and sends an analogue
signal of airborne smoke intensity to a remote or integrated
Display Module.
This information is then relayed from the Display Module to
a central fire alarm control panel or a building management
system via intelligent interfaces or relay contacts. The
VESDA LaserPLUS Display Module is programmable, enabling
sensitivity and alarm level settings to be selected by the
user.
De GIELLE te all its sensitivity, VESDA LaserPlus can
actually reduce the number of unnecessary and disruptive
false alarms. Unlike other HSSD – high sensitivity smoke
detection – systems that can be triggered by insects or
dust, VESDA LaserPlus uses a unique monitored dual-stage
filter cartridge to trap most larger particles while
allowing only the smaller smoke particles to pass through
for analysis. Additionally, the sensitivity level can be set
having first sampled the ambient smoke and air contamination
levels.
Expert
installation
Such sophisticated
technology calls for the highest level of fire engineering
competence at every stage from design through installation,
commissioning and aftercare. As one of the country’s
leading fire safety specialist engineering companies, ISO
9001 and LPS 1204 approved GIELLE is ideally placed to
handle every aspect of a VESDA LaserPLUS installation.
The company uses the very latest computer-aided-design
technology in its work, and every aspect of each contract is
carried out under the strictest quality assurance regimes.
GIELLE also undertake the vitally important regular
maintenance of VESDA LaserPlus installations.
