Description
Honeywell R7849A1023 Ultraviolet Flame Amplifier – 7800 Series Compatible, Standard, Non-Self-Check (2.0 / 3.0 sec FFRT)
The Honeywell R7849A1023 is a standard UV flame signal amplifier designed for use with Honeywell 7800 Series burner control relay modules. It accepts input from compatible UV flame detectors (C7027A, C7035, C7044) and provides a reliable indication of flame presence in gas or oil-fired burners. This amplifier does not include self-checking circuitry, making it suitable for applications that do not require dynamic flame detection validation.
Flame failure response time (FFRT) is selectable at 2.0 or 3.0 seconds, and flame strength is indicated on a 0.0 to 5.0 Vdc scale via onboard test jacks.
