The VESDA Industrial Laser is the first Aspirational Smoke Detection (DHA) system with early warning function, designed to protect industrial applications and harsh environments up to 2,000 m2. The VLI detector combines a fail-safe smart filter with an advanced clean air barrier that, in addition to protecting optics, offers efficient absolute detection and a long-life smoke detection chamber that eliminates the need for recalibration. It allows a sensitivity ranging from 0.005% to 20% obscuration per meter, allowing up to 24 sampling points in Class A, 28 sampling points in Class B and 60 sampling points in Class C. This model allows a network of sampling up to 360 meters of total tube length.
