The Honeywell R7849A1015 0.8 OR 1 SEC Flame FAILURE RESPONSE TIME.
Honeywell R7849A1015 Flame Amplifier – Ultraviolet UV Module (0.8 / 1.0-Second FFRT)
Product Overview
The Honeywell R7849A1015 Flame Amplifier is a UV flame amplifier module designed for use with Honeywell 7800 Series relay modules. This ultraviolet flame amplifier provides fast and dependable flame detection with a selectable flame failure response time (FFRT) of 0.8 or 1.0 seconds. It delivers a 0-5 Vdc flame signal output and works with ultraviolet flame sensors such as C7027A, C7035A, and C7044.
The R7849A1015 is color-coded purple for ultraviolet detection type and includes built-in flame signal test jacks for easy measurement of flame strength. With a keyed plug-in design, this Honeywell UV flame amplifier offers quick installation, accurate monitoring, and reliable protection for commercial and industrial burner safety systems.
