Aspirating smoke detector providing very early warning for industrial applications and harsh environments.

This configuration protects environments of up to 2000 m².

The VLI detector combines a fail-safe intelligent filter with an advanced clean-air barrier for optics protection, allowing the use of absolute detection and a long detection chamber life without the need for re-calibration.
