The Honeywell R7849B1013 0.8 OR 1 SEC Flame FAILURE RESPONSE TIME.
Honeywell R7849B1013 Flame Amplifier – Ultraviolet Ampli-Check Module (0.8 / 1.0-Second FFRT)
Product Overview
The Honeywell R7849B1013 Flame Amplifier is an ultraviolet (UV) Ampli-Check amplifier module designed for use with Honeywell 7800 Series relay modules. It delivers fast and reliable flame detection with selectable flame failure response times (FFRT) of 0.8 or 1.0 seconds. This UV flame amplifier provides a 0-5 Vdc flame signal output, works with UV sensors such as C7027A, C7035A, C7044 (commonly used “Mini-Peeper” sensors), and includes built-in flame signal test jacks. The module is color-coded purple for UV detection type and features a keyed plug-in PCB edge connector for proper installation and secure fit in burner safety systems.
Key Features
Selectable FFRT: Choose between 0.8 second or 1.0 second flame failure response time for quicker safety shutdown.
Ultraviolet detection type: Designed for UV flame sensors including C7027A, C7035A, C7044.
Flame signal output: 0-5 Vdc output with flame signal test jacks for monitoring flame strength.
Ampli-Check self-checking: Diagnostic functionality monitors amplifier and UV detector components for faults.
Relay compatibility: Plug-in keyed design works with Honeywell 7800 Series relay modules.
Color coding: Purple label clearly identifies this as an ultraviolet flame amplifier.
