VESDA & FAAST FLEX Detectors There are 15 products.

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 250m� (2,500 sq. ft.), and the VLF-500 covers areas up to 500m� (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.

Reliable, early warning smoke detection for challenging environments.

The Industrial VESDA VLI is the first very early warning aspirating smoke detector purpose-built for the protection of industrial applications of up to 2,000 square meters (20,000 sq. ft.). Housed in a ruggedized industrial enclosure and incorporating patented longlife, fail-safe filter technology along with other best-inclass VESDA features, the VLI sets a new benchmark for the protection of industrial applications. The detector showcases a host of features specifically designed to address the common challenges of industrial applications such as high background levels of airborne particles, detector longevity and deterministic maintenance.

• High immunity from the effects of contamination and degredation
• Simplifies the deployment of ASD in harsh environments
• Purpose-built for harsh and industrial applications
• Lower installation and maintenance costs
• Reliable smoke sensitivity over time and detector longevity

The VESDA VLC by Xtralis is an aspirating smoke detector that provides very early warning in single and small environments where space is at a premium.

The VESDA VLC aspirating smoke detector is available in two versions, one that interfaces via relays only (RO) and one that interfaces via relays and VESDAnet (VN). The VESDA VLC-EX detector has been specifically designed to provide all the benefits of ASD for the protection of hazardous applications with Zone 2 classification.

Typical Applications

The VESDA VLC offers a simple, cost-effective solution for the protection of single and smaller environments such as:

• Small archives
• Production machinery
• Ceiling voids
• Prison cells
• Wet benches
• Data storage cabinets
• Critical process tools

The VESDA VLP by Xtralis is the flagship of the VESDA aspirating smoke detector product line.

Using unique detection principles, the VLP has an alarm sensitivity range of 0.005%–20% obscuration/m (0.0015%–6.25% obscuration/ft). The detector can form part of a modular system with the display, programmer and VESDAnet modules installed in a remote location or as a “self-contained” system by replacing the detector’s panels with display and/or programmer modules. With the display and programmer remote, the user interfaces for many Xtralis VESDA VLP detectors can be grouped together in a cabinet for easy programming.

The VESDA VLS by Xtralis is similar to the flagship VESDA VLP aspirating smoke detector but also includes a valve mechanism in the inlet manifold and software to control the airflow from the four sectors (pipes).

This configuration enables a single VESDA zone to be divided into four separate sectors, for example, distinguishing between separate voids within a room. The VLS locates the origin of smoke by identifying the first sector (pipe) with the highest level of smoke and then continues to sample from all sectors to monitor fire growth. The VLS provides four alarm levels for each individual pipe (Alert, Action, Fire 1 and Fire 2). Sector factors (sensitivity) can be set individually to ensure the optimal alarm thresholds are applied for each sector. An extra LED indicates when the first alarm sector has been established.
