Honeywell FS20X Flame Detector
Model No :
Honeywell -FS20X
Part Code :
FS20X

Overview

The FS20X is a Multi-Spectrum and UV/Dual IR/VIS Flame Detector with a proven UV solar-blind sensor. The FS20X exhibits faster false-alarm free response to fire over a wider temperature range and with a much longer detection range compared to conventional UV/IR detectors. It has detection range in excess of 200 feet (very high sensitivity setting) for the detection of a one square-foot Heptane reference fire and has a cone of vision greater in volumetric coverage than most UV/IR detectors.
