Honeywell FS20X Flame Detector

The Honeywell FS20X is a Multi-Spectrum and UV/Dual IR/VIS Flame Detector with a proven UV solar-blind sensor. The Honeywell FS20X Flame Detector exhibits 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.
