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.
