Aspirating smoke detector providing very early warning for small business-critical environments.

This configuration protects environments of less than 250 m² (VLF-250-00), or 500 m² (VLF-500-00). 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. Detector status information is communicated on the detector display and via relays or optional interface cards.
