VLF-250 XTRALIS VESDA Air Sampling Analyzer Up to 2 500 sq. ft. Coverage

The VESDA VLF-250 Air Sampling Smoke Detector provides very early warning smoke detection performance for the protection of small businesscritical environments of 2 500 sq. ft. or less.

 The air sampling detection concept works by continually drawing ambient air through sampling holes in a pipe network. Upon entering the unit the sampled air is fi ltered and passed into the detection chamber where light scattering technology detects the presence of very small amounts of smoke.
