Essential details：85UVF1A-1QD Fireye Phoenix Series 2 type 85UVF/IRF flame scanners
Product Description
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.
The Phoenix 85UVF/IRF is available in multiple models differentiated by spectral range, levels of hazardous area certifications and agency approvals. Refer to Table 1 on page 3 for an overview of model numbers versus product certifications. Versions with stainless steel housings are also available.
The Phoenix 85UVF/IRF flame scanner is powered by 24Vdc. Electrical connection is via an 8-pin electrical quick-disconnect (QD). An analog 4 to 20mA output of flame strength is standard.
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 Ex II 2 G/D hazardous areas.

Using the keypad the scanner flame failure response time can be set by the user to the desired timing.
Each unit comes from the factory preset at 1 second. To change the factory default to a different FFRT, see Set-Up Procedure below. To verify the current FFRT setting, press and hold the UP push button with the scanner in the normal operating mode. The “flame strength” LED set will display 1st , 2nd, 3rd, or 4th LED as appropriate and these correspond to the FFRT in seconds.
FFRT Set-Up Procedure
If the Flame Failure Response Time needs modifying, follow the procedure listed below. Press both the Target Flame Select and Background Flame Select buttons simultaneously. Use the up button to drive the LEDs until LED number [8] (pass code) is illuminated on the flame strength
LEDs right hand set.
Press both the Target Flame Select and Background Flame Select buttons simultaneously.
Press UP or DOWN push buttons to select required FFRT (the selected FFRT is displayed on the flame strength LEDs as either 1 st, 2nd, 3rd, or 4th). Once you have selected the correct value, Press both the Target Flame Select and Background Flame Select buttons simultaneously to store. The stored value can be displayed and checked at any time while in the normal run mode. Pressing and holding the UP pushbutton at any time will display the stored FFRT on the flame LEDs right hand set. Verify that the correct FFRT has been stored.
Commissioning the Scanner /Learning the Flame Condition
Step 1 – Enter the pass code
Press both the Target Flame Select and Background Flame Select buttons simultaneously. Use the up button to drive the LEDs until LED number [5] (pass code) is illuminated (if you pass the required point use the down button to correct). Press both the Target Flame Select and Background Flame Select buttons simultaneously.
