| Vesda laserplus: a gielle rating smoke detection |
|
| |
|
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.

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.

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.

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.
