Description
The VLF-250/500 detector is a very early warning smoke detector designed to protect small, business-critical environments of up to 250 m² (2500 sq. ft., VLF-250) or 500 m² (5.000 sq. ft., VLF-500).
The detector works by continually drawing air into sampling holes in a pipe network. The air is filtered and passed into a detection chamber where light scattering technology detects the presence of very small amounts of smoke.
