The Fire Sentry FS20X is a Multi-Spectrum and UV/Dual IR/VIS Fire and Flame Detector with a proven UV solar-blind sensor. The Fire Sentry FS20X has a faster false-alarm free response to fires over a wider temperature range and with a much longer detection range compared to conventional UV/IR Detectors.
The conventional and older technology UV/IR Detectors which uses narrow band 4.3 micron IR Sensors will not respond to smoky fires if the Detector lens is contaminated with oil and other substances. Older technology UV/IR Detectors will not alarm to fires when they are installed behind glass windows.
The Fire Sentry FS20X is designed to alarm to all types of fires and in all industrial environmental conditions. If the signal of the FS20X is degraded due to heavy smoke or contamination, the Fs20X’s WideBand IR, Near Band IR and Visible Sensors will still alarm, but at reduced sensitivity and slower response time.
The Fire Sentry FS20X Flame Detector has a detection range of 61m (200ft) for the detection of a one square-foot Heptane reference fire. The cone of vision of the FS20X is greater than any other Multispectrum IR Detector.
