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

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).

He 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.

The VESDA Ex d by Xtralis aspirating smoke detector has been designed to provide very early fire detection  within hazardous areas that may contain flammable gases. The VESDA Ex d satisfies the need of those end users who implement risk-based, fire-engineering practices and recognize the value of their critical assets.

The VESDA VFT-15 by Xtralis is a unique and versatile high-sensitivity aspirating smoke detector able to pinpoint the source of incipient smoke to speed response, enhance investigation and minimize business disruption and downtime where location is critical and a visual search is impossible to perform quickly. VESDA VFT is the only aspirating smoke detector on today’s market to provide identification of up to 15 protected areas.
