R7849A1023 Honeywell Flame Amplifier 2 OR 3 SEC Flame FAILURE RESPONSE TIME. Honeywell R7849A1023 Flame Amplifier – Ultraviolet UV Module (0.8 / 3.0-Second FFRT) Datasheet Installation Guide Product Overview The Honeywell R7849A1023 Flame Amplifier is a UV flame amplifier module designed for use with Honeywell 7800 Series relay modules. This ultraviolet flame amplifier offers fast flame detection with selectable flame failure response times (FFRT) of 0.8 or 3.0 seconds. It delivers a 0-5 Vdc flame signal output, works with Mini-Peeper sensors (UV detectors) such as C7027, C7035, or C7044, and includes flame signal test jacks for flame strength verification. The R7849A1023 is color-coded purple to identify UV detection type, and features a keyed plug-in PCB edge connector for proper alignment. Key Features Selectable FFRT: 0.8 second or 3.0 second flame failure response time for burner safety control. UV flame detection compatibility: designed for use with ultraviolet sensors like C7027, C7035, C7044. Flame signal monitoring: 0.0-5.0 Vdc flame signal output with built-in test jacks for verification. Plug-in keyed edge connector: ensures secure, accurate installation into 7800 Series relay modules. Color coding: Purple label denotes UV flame amplifier detection type. Solid-state design: durable and reliable amplifier performance for combustion safety.
