Application
VLF-250
The LaserFOCUS detector is a very early warning smoke detector (Aspirating Smoke Detector ASD)
designed to protect small, business-critical environments of less than 250 sqm.
Function
The detector works by continually drawing air into sample 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 C-NET interface card is integrated.
