Description

With over 35 years proven market leadership, VESDA VLI was created to provide an effective and reliable Very Early Warning Smoke Detector designed to meet the specific and unique challenges of Industrial applications and harsh environments and designed to:

Withstand harsh environmental conditions
Maintain its sensitivity over the life of the detector
Provide best in class detection performance
Provide a lower TCO
The design of Industrial VESDA VLI enables the product to be deployed into many industrial applications without special application engineering, system design support and enhanced maintenance procedures that were previously required. Key features that enable deployment into these environments include:
– World’s first patented fail-safe intelligent filter to eliminate the need for external filters and significantly extend service life
– Inertial secondary filtration removes large dust particles thereby further extending detector service life and safeguarding against nuisance alarms
– IP66 enclosure to provide protection from the environment eliminating the need for costly enclosures
– Extending total aggregate sampling pipe capability up to 360 m (1,181 ft) to cover larger areas with fewer detectors

Another industry first is the 100% modular design. This enables field replacement of individual detector components reducing down time and spare part inventory. No longer does the entire detector have to be replaced.

Fundamental to Industrial VESDA VLI’s ability to provide consistent performance throughout its service life is the use of VESDA’s patented absolute detection technology, that uses a clean air barrier to keep the components of the optical detection chamber clean. In addition, a new, innovative and patented Clean Air Zero feature provides the highest degree of detector stability, while maintaining absolute smoke detection.

VESDA does not rely on any “predictive” algorithms to compensate for short term or long term drift. These approaches inevitability lead to degraded detector performance and extended detection times, if not missing fire events completely.
