VESDA Laser Focus

The VESDA VLF by Xtralis is an aspirating smoke detector ideal for small, business-critical spaces.

Available in two models, the VLF-250 covers up to 250m2 (2,500 sq. ft.), and the VLF-500 covers areas up to 500m2 (5,000 sq. ft.).

The continued trend towards smaller and more concentrated critical high-technology business operations has driven the need for more flexible and focused very early warning smoke detection solutions to protect these high value assets. Understanding and responding to these needs, the VESDA VLF extends the product range by offering VESDA detection performance for smaller critical areas previously overlooked or limited to conventional protection methods.

Typical Applications

• Local telecommunication exchanges
• Air handling units
• Smaller server rooms
• Correctional facilities
• Control rooms
• Utility control hubs
• Switch rooms
• Railway signal hubs
• Storage facilities
• Cabinets
• Hazardous areas (Class 1 Div 2)
• Substations

VESDA VLF multiple point air-sampling technology works by utilizing a highly efficient aspirator that continually draws air into its laser detection chamber via a pipe network. Accurate assessment of the air sample using calibrated detection and long detector life expectancy, are assured with a patented dual stage filtration process that both eliminates background ‘noise’ and preserves the optical integrity of the laser technology with its clean air bleed. The result of which is an unchallenged detection process able to provide reliable and consistent very early warning smoke detection performance across a diverse range of applications.
