Cerberus LaserFOCUS VLF-250 Aspirating Smoke Detector with display
The Cerberus LaserFOCUS VLF-250 Detector is a very early warning Smoke Detector (aspirating Smoke Detector ASD) designed to protect small‚ business-critical environments of less than 250 m2.
The Cerberus LaserFOCUS VLF-250 Smoke 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. The Cerberus LaserFOCUS VLF-250 Detector status information is communicated on the detector display. The FDnet/C-NET interface card is integrated.
