System compatibilitySB49600-91 belongs to Fireye SB series flame scanner family. Compatible with Fireye SB560xxAA flame safeguard controllers and Eclipse VeriFlame burner control system. Designed for intermittent cycling gas burners, commercial boilers and process furnaces. It is non self-check UV scanner, applicable for burners cycling at least once every 12 hours to exercise safety circuit. Widely used as spare replacement for combustion flame monitoring system.
FunctionSB49600-91 is straight UV flame scanner manufactured by Fireye. It captures ultraviolet radiation emitted by burner flame and converts flame signal and transmits to SB series flame safeguard controller. The controller judges flame presence or loss according to received UV signal. Non self-check design, relies on regular burner cycling to complete safety verification. It is suitable for gas burner flame detection. Magnifying lens accessory can be installed when flame signal is insufficient. Widely deployed for industrial boiler flame monitoring and spare replacement.
InstallationFollow lockout/tagout safety procedure before installation. Mount SB49600-91 on burner sight port via 1/2" NPT thread. Align the straight sight line to target flame zone, keep distance within 18 inch. Route shielded cable to SB controller terminals strictly follow Fireye wiring schematic. Complete flame signal strength test after commissioning. Add heat insulator if the mounting area has high ambient temperature.

FeatureOriginal Fireye SB49600-91 straight UV flame scanner,non self-check,185-260nm UV spectrum,1/2"NPT thread,UL & FM safety certified. This spare unit is used for industrial gas boiler burner flame detection maintenance and hardware replacement.
DiagnosticLow flame signal: Inspect lens soot contamination, sight alignment, or install optional magnifying lens. No flame output signal: Check UV tube aging, wiring breakage and terminal connection. Intermittent flame signal: Verify high temperature thermal influence, vibration and cable shielding. Scanner overheat: Add heat insulation coupling, check furnace radiant heat transfer.
Product BriefSB49600-91 is Fireye straight non self-check UV flame scanner with 1/2"NPT thread,matched with SB series flame safeguard controllers,classic spare for gas burner flame detection system.
