Honeywell R7849B1021 Flame Amplifier – UV Ampli-Check Module (2.0 / 3.0-Second FFRT)
The Honeywell R7849B1021 2 OR 3 SEC Flame FAILURE RESPONSE TIME.
Product Overview
The Honeywell R7849B1021 Flame Amplifier is an ultraviolet flame amplifier with Ampli-Check self-checking diagnostics, engineered for use with Honeywell 7800 Series relay modules. It provides selectable flame failure response times (FFRT) of 2.0 or 3.0 seconds for dependable burner safety control. The amplifier delivers a 0–5 Vdc flame signal output, works with Mini-Peeper style UV sensors such as C7027A, C7035A, and C7044, and includes built-in flame signal test jacks for accurate monitoring. With a purple label to identify UV detection type and a keyed plug-in design, the R7849B1021 is a reliable replacement or upgrade option for commercial and industrial flame safeguard systems.
