LaserFOCUS VLF-500

Aspirating smoke detector with display

Stock no. VLF-500-SIE

Stock no. VLF-500-SIE

The LaserFOCUS detector is a very early warning smoke detector (aspirating smoke detector ASD) designed to protect small, business-critical environments of less than 500 m2. 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.

The FDnet/C-NET interface card is integrated.
