Honeywell FS24X Flame Detector

The Honeywell FS24X is a Multi-Spectrum Triple IR (IR/IR/IR/Visible) Flame Detector. Sophisticated software algorithms and dual microprocessors ensure that the FS24X has the highest Flame Detection performance combined with optimal false alarm rejection. A combination of outputs makes the Honeywell FS24X Flame Detector a truly versatile Detector for today’s demanding industrial requirements.

The Honeywell FS24X has a detection range greater than 200 feet (Very High Sensitivity setting) for the detection of a one square-foot Heptane reference fire and has a cone of vision far greater in volumetric coverage than any other Multi-Spectrum IR Detector.
