The Fireye Phoenix Series 2 type 85UVF/IRF flame scanners are microprocessor based devices utilizing a
solid state flame detection sensor. The Phoenix flame scanners incorporate an internal flame relay with automatically set ON/OFF thresholds, thereby eliminating the need for a remote flame amplifier or flame switch.
Phoenix scanners detect the amplitude of the modulations (the flame “flicker”) that occur within the targeted
flame, over a wide frequency. During the scanner setup procedure, the amplitudes of the target flame are
automatically stored by the flame scanner, together with optimum ON/OFF criteria. The appropriate sensor
gain is automatically selected. Phoenix scanners incorporate full self-diagnostics and electronic selfchecking.
