Product Spotlight – VESDA LaserFOCUS (VLF) Aspirating Smoke Detector

3 mins read

Xtralis VESDA LaserFocus (VLF) aspirating smoke detectors provide first-rate very early warning air-sampling smoke detection for small, business-critical space such as server rooms, switch rooms and equipment cabinets. 

VESDA VLF detectors use laser-based absolute smoke detection technology and dual-stage dust filtration to provide an extremely reliable and very early warning of a potential fire incident.

How it Works

VESDA VLF aspirating smoke detectors use powerful aspirators to actively draw air from the protected area via discrete sampling holes in a network of aspirating smoke detection pipes into its detection chamber. Before entering the detector, the air passes through a dual-stage dust filtration system to ensure that the detection chamber remains free from contaminants. 

Once the air enters the chamber, laser-based, light scattering technology is used to detect the presence of smoke. If even the smallest amount of smoke is detected, the systems intuitive “Smoke Dial” display indicates that there is a potential fire and the relevant information is reported to the fire alarm control panel via relays or optional interface cards.

2 Variants to suit 250m2 and 500m2 areas
VESDA LaserFOCUS detectors are available in two variants to cater for different size areas. VESDA VLF-250 detectors are designed to cover areas up to 250m2 while VESDA VLF-500 detectors cater for areas up to 500m2.
Ease of Installation
VESDA-VLF detectors do not require a special interface or software programming tools and provide “out-of-the-box” operation.
Ultrasonic Flow Sensing
VESDA VLF detectors use Xtralis’ patent-pending Ultrasonic Flow Sensing to provide a direct reading of the sampling pipe flow rate. Ultrasonic Flow Sensing is unaffected by pressure and air temperature changes and is impervious to contamination.
Automatic Smoke and Flow Fault Thresholds
VESDA’s AutoLearn™ feature further assists installation by assessing the environmental conditions of the protected area and automatically setting suitable smoke alarm and flow fault thresholds.

    FyreLine EN54 Fixed Linear Heat Detection: Unaffected by the Weather

    Fire detection systems installed in open, exposed or temporary environments face a challenge that indoor systems rarely have to deal with: the weather itself. Scaffolding can wrap around a live building for months at a time, cable trays and building envelopes sit fully exposed to the elements, and construction sites are, almost by definition, unprotected. […]

    VESDA-E VEP for Superstores

    Superstores are large-format retail environments that combine extensive sales floors with backroom storage, refrigeration plant, loading bays and, in many cases, in-store bakeries, delicatessens and other food preparation areas. They typically operate long trading hours, hold significant stock value and see high footfall from both customers and staff throughout the day. Effective fire detection is […]
