The most important part of any Fire Protection Solution is the very early detection of smoke.
Vesda is a fire detection system that offers the earliest possible warning of a potential fire. A system that will ensure that business is never disrupted and that nuisance alarms are eliminated. A system that can adapt to the ‘unique’ characteristics of any given environment.
One that delivers high performance through its high quality design and it’s dedicated global sales and distribution channels. With over 50,000 units installed worldwide, the VESDA name has become synonymous with high performance very early warning smoke detection.
The Earliest Possible Fire Warning
All escalating fires have four stages: Incipient (pre-combustion), Visible Smoke, Flaming Fire, and Intense Heat. This chart shows the progression of fire over a time period. Note that the incipient stage of smouldering fires provides the widest window of opportunity to detect and control the spread of fire, before it takes hold causing major damage and disruption. VESDA can be configured to generate multiple alarms within this window.
How Does VESDA Work?
VESDA’s high quality aspirating smoke detectors work by continually drawing air into the pipe network by a highly efficient aspirator. A sample of this air is then passed through a dual stage filter. The first stage removes dust and dirt from the air sample before it allows the sample to enter the laser detection chamber for smoke detection. The second ultra fine stage has the unique feature of providing an additional clean air supply to keep the optical surfaces within the detector clear from contamination and to ensure the stable calibration and long life of the detector.
PRODUCT
VESDA-E VEP (Mainstream ASD)
The VESDA-E VEP series of smoke detectors bring the latest and most advanced detection technology to provide very early warning and the best nuisance alarm rejection to a wide range of applications. Built on the Flair detection technology and years of application experience, VEP detectors achieve consistent performance over their lifetime via absolute calibration. In addition, the VEP delivers a range of revolutionary features that provide user value.
VESDA-E VES (Sector Addressable ASD)
The VESDA-E VES can identify and monitor smoke density by individual sampling pipe (sector) which allows a single zone to be divided into four separate sectors; for example, distinguishing between separate aisles within a data room. Sector addressability enables the user to respond to a potential fire event quickly by reducing the search area.
VESDA-E VEU (Highest Sensitivity ASD)
The VEU series of aspirating smoke detectors are the premium detector of the VESDA-E range. An Ultra-wide sensitivity range; 15 times greater than VESDA VLP, and provision for more sampling holes provide an increased coverage in high airflow applications by at least 40%. A range of revolutionary new features provide unsurpassed detection performance, flexibility, field programmability, connectivity and reduced total cost of ownership.
VESDA VLF
The VEU series of aspirating smoke detectors are the premium detector of the VESDA-E range. An Ultra-wide sensitivity range; 15 times greater than VESDA VLP, and provision for more sampling holes provide an increased coverage in high airflow applications by at least 40%. A range of revolutionary new features provide unsurpassed detection performance, flexibility, field programmability, connectivity and reduced total cost of ownership.
