System Components

Phoenix Scanners 85UVF and IRF

The Fireye Phoenix type 85UVF/IRF flame scanners

are microprocessor based devices utilizing a solid state

flame detection sensor. The Phoenix flame scanners incor-

porate 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 modula-

tions (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 automati-

cally stored by the flame scanner, together with optimum

ON/OFF criteria. The appropriate sensor gain is automati-

cally selected. Phoenix scanners incorporate full self diag-

nostics and electronic self checking.

The Phoenix 85UVF/IRF is available in multiple models differentiated by detection cell type, levels of

hazardous area certifications and agency approvals.

The Phoenix 85UVF/IRF flame scanner is powered by 24Vdc. Electrical connection is via an 8-pin electri-

cal quick-disconnect (QD). An analog 4 to 20mA output of flame strength is standard.

Operator interface to the Phoenix scanner is via a pushbutton keypad and informative LEDs. These provide

continuous indication of flame signal, flame relay status, scanner status as well as selected mode of opera-

tion. Simplified keystroke routines are used for setup and this can be completed in seconds. For remote

interface, outputs are provided for flame switch, fault relay and 4 to 20mA flame strength.

Note: The Phoenix QD models with electrical quick-disconnect have replaced the original models

equipped with ten feet of captive cable. The QD models (with 59-546-x cables) are suitable for use in Class

I Division 2 hazardous areas, thereby eliminating the need for "EX" models. The "CEX" models remain

unchanged for use in EEx d IIC T6 hazardous areas.
