Description

The VESDA VLI Intelligent Filter is an essential component for VESDA VLI aspirating smoke detectors, designed to ensure early smoke detection in harsh and dirty environments. This fail-safe filter, working with an advanced clean-air barrier, significantly reduces pollution in air samples before they reach the detection chamber. This filtering process drastically extends the detector’s operational lifespan and maintains consistent sensitivity, allowing reliable performance in challenging conditions.

The detector constantly monitors the differential flow between filtered and unfiltered air entering its manifold. As contaminants accumulate, the flow of filtered air decreases. When this reduction falls below a set threshold, the detector reports a fault condition, indicating the Intelligent Filter requires replacement. Although a two-year replacement interval is recommended, environmental conditions dictate the actual frequency.

Replacing the filter involves placing the detector in standby, removing the old unit, installing the new one, and then resetting the “Intelligent Filter Life” via Xtralis VSC software. Eurofyre, an authorised Honeywell and Xtralis distributor, supplies the VESDA VLI Intelligent Filter.
