Description
- Ultraviolet Signal Processing: Converts raw ultraviolet radiation inputs from connected Minipeeper sensors into standard 0.0 to 5.0 VDC flame signal strength readings for 7800 Series controllers.
- 2.0 / 3.0 Second FFRT Timing: Delivers rapid Flame Failure Response Time (2.0 or 3.0 seconds) to initiate immediate safety shut-offs and mitigate unburned fuel hazards during flame-outs.
- Minipeeper UV Sensor Compatibility: Operates seamlessly with Honeywell C7027A, C7035A, and C7044 mini UV flame detectors across gas, oil, and combination fuel applications.
- Keyed Edge Connector Installation: Plugs directly into 7800 Series relay modules via a keyed printed circuit board edge connector that prevents improper orientation and speeds up servicing.
- Front Diagnostic Test Jacks: Features accessible front-face test points that allow service technicians to quickly measure flame signal voltage using a standard 1M ohm digital voltmeter.
- Purple Color-Coded Casing Label: Includes a distinct purple identification label to ensure fast visual identification of the ultraviolet flame detection technology inside the control cabinet.

Description
The Honeywell R7849A1023 Ultraviolet Flame Signal Amplifier is a plug-in solid-state module engineered to translate ultraviolet radiation signals into actionable flame data for Honeywell 7800 Series burner control systems. Designed for use with C7027, C7035, and C7044 Minipeeper UV flame detectors, this module features a 2.0 or 3.0 second Flame Failure Response Time (FFRT) to quickly trigger safety shut-offs during unexpected flame outages. Equipped with front-panel test jacks for DC signal voltage measurement, a keyed printed circuit board edge connector for error-free installation, and a distinct purple color-coded label, the R7849A1023 provides accurate flame indication, robust signal stability, and simplified field maintenance across commercial heating boilers, industrial furnaces, and process burners.
Frequently Asked Questions
Which Honeywell flame detectors are compatible with the R7849A1023 flame amplifier?
The R7849A1023 is designed to operate with Honeywell Minipeeper ultraviolet flame detectors, including the C7027A, C7035A, and C7044 series UV sensors.
What is the acceptable flame signal voltage range for the R7849A1023 amplifier?
The amplifier outputs a flame signal strength ranging from 0.0 to 5.0 VDC. A minimum reading of 1.25 VDC is required for reliable burner operation and to prevent nuisance shutdowns.
Is the Honeywell R7849A1023 a self-checking flame amplifier?
No, the R7849A1023 is a standard, non-self-checking UV flame amplifier. It is intended for intermittent-duty burner applications that cycle off at least once every 24 hours.
Which burner control modules accept the R7849A1023 UV amplifier?
The R7849A1023 plugs directly into Honeywell 7800 Series microprocessor-based relay modules, such as the RM7800, EC7800, RM7840, and RM7890 series controllers.
How do technicians measure the flame signal voltage on an installed R7849A1023?
Technicians insert meter leads from a 1M ohm/volt DC voltmeter into the two test jacks located on the front face of the amplifier module while the burner is firing.
