Description
VESDA VLI is an industry-first early warning aspirating smoke detection (ASD) system, designed to protect industrial applications and harsh environments of up to 2000 m² and 1600 m². It combines a fail-safe Intelligent Filter (patent pending) with an advanced clean-air barrier for optics protection, allowing the use of absolute detection and a long detection chamber life without the need for recalibration.
The VLI detector features a robust IP66-rated enclosure, which provides complete protection against dust ingress and strong water jets from all directions. In the majority of industrial applications, specifically in very harsh environments, this eliminates the need to use expensive external IP enclosures, thus simplifying and reducing the cost of installation.
The VLI detector is equipped with a powerful aspirator that provides a total pipe length of 360 m (1181 ft). It is fully supported by ASPIRE, VSC, and VSM4 software applications, which facilitate ease of pipe network design, system commissioning, and maintenance, together with compatibility with existing VESDA installations.
The AutoLearn™ commissioning assistant reduces setup time and ensures optimum alarm and flow thresholds in a range of environments. The VLI detector is inherently less prone to nuisance alarms due to the intelligent filter, lint trap, sub-sampling probe, and secondary filter. Coupled with its modular design, VLI offers a lower total cost of ownership over the life of the product.
