1 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 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 an IP54 rated enclosure
l detector longevity
l the need for in-field maintenance

The detector easily interfaces with fire warning and fire suppression release systems, and can be
integrated into a building management system (BMS).
