Honeywell FSL100 UV, UV/IR and IR3 Flame Detector

FSL100 is Honeywell’s compact range of flame detectors in three versions: UV, UV/IR and triple IR (IR3). Range 25 m (UV, UV/IR) or 35 m (IR3), cone of vision of at least 90°, 4-20 mA and relay outputs as standard, 10-28 VDC supply. UV-resistant GRP housing, IP65, for indoor and outdoor use, ATEX zone 2/22, with EN54-10 and FM3260 approvals depending on the version.

How do FSL100-UV, FSL100-UVIR and FSL100-IR3 differ?

The three FSL100 versions differ in sensing technology, range and the fires they suit. FSL100-UV: UV sensor, 25 m range; suited to cold storage, laboratories, fume hoods and hydrogen storage areas, and to materials burning at low temperatures such as sulphur. FSL100-UVIR: UV/IR, 25 m range; analyses flame flicker frequency to reduce false alarms and detects a wide range of hydrocarbon and non-hydrocarbon fires. FSL100-IR3: triple IR, 35 m range; suited to liquid hydrocarbon and dirty fires or fires with a lot of smoke, and less affected by window contamination.
