Introduction
The VESDA VLI is an aspirating smoke detector (ASD) that provides very early warning of fire conditions by
drawing air samples through an air sampling pipe network.
The VLI detector is especially designed to operate in industrial applications under harsh and dirty
environments. It incorporates features that specifically address the common challenges of industrial
installations, including:
l
high background levels of airborne particles
l
the need for environmental enclosures
l
detector longevity
l
the need for on-site maintenance
