The Notifier FSV-951R VIEW is a high-sensitivity photoelectric smoke detector designed for Very Early Warning Fire Detection and will protect valuable assets and operations where systems must remain functioning at all times. FSV-951R VIEW detector features a smoke-sensing chamber and patented optic block design to amplify signals from smoke, but diminish stray internal reflections that can cause false alarms. New LED technology allows this detector to achieve sensitivity levels from 0.02 percent-per-foot to 2 percent-per-foot obscuration - up to 25 times greater than a standard photoelectric detector. The extensive software processing includes multi-alert drift compensation, internal self-diagnostics, and superior transient signal rejection algorithms to produce unprecedented stability at ultra-high sensitivities across the full temperature range. This system provides point identification of the fire location through addressability and offers complete supervision of both wiring and detector.
