The NOTIFIER FSV-951R VIEW is high-sensitivity photoelectric smoke detectors 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 designed 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 supervi- sion of both the wiring and detector.

FlashScan® (U.S. Patent 5,539,389) is a communication pro- tocol developed by Notifier for high speed communication between analog intelligent devices. Intelligent devices commu- nicate in a grouped fashion. If one of the devices within the group has new information, the panel CPU stops the group poll and concentrates on single points. The net effect is response speed greater than five times that of other protocols.

Using the enhanced intelligent sensing algorithms, the intelli- gent sensing system provides drift compensation (meeting UL requirements as a calibrated sensitivity meter), maintenance alert (3 levels), selection of 9 alarm levels and 9 pre-alarm lev- els, and report of drift compensation used and recent peak val- ues. The system includes a self-learn sensitivity adjustment to set the pre-alarm level just above the peak levels sensed over long periods of time for each detector’s actual environment. The system includes multi-detector algorithms that permit one sensor to consider readings from adjacent sensors to provide faster detection of fires.

• UL 268 listed for Open Air Protection (0.5%/ft. to 2.0%/ft. obscuration)
• UL 268 listed for Special Applications (0.02%/ft. to 0.5%/ft. obscuration)
• UL 268A listed for Duct Applications allowing both in duct and within System Sensor models DNR and DNRW duct smoke detectors
