R7849A1015
ULTRAVIOLET FLAME AMPLIFIER
TEMP: -40°C TO 60°C
REV: E
The Honeywell R7849A1015 is an ultraviolet (UV) flame amplifier designed to detect the presence of flame by sensing ultraviolet radiation emitted during combustion. As a core component within burner management and fire alarm systems, this amplifier processes the signal from a UV scanner and provides the reliable flame-proving output required to allow or shut down burner operation safely. Rated for an operating temperature range of -40°C to 60°C, it is suited to demanding shipboard environments. In marine fire detection and burner control applications, accurate and fast flame response is operationally critical, making a dependable amplifier module essential to system integrity.
Key Features
✓ Ultraviolet flame sensing technology provides reliable flame discrimination, minimising false signals in challenging combustion environments.
✓ Operating temperature range of -40°C to 60°C as specified, making it suitable for both cold-climate operations and warm machinery space installations.
✓ Revision E designation indicates a current production revision — compatibility with specific burner control panels or flame relay bases should be confirmed against system documentation.
✓ Designed for use within burner management and flame supervision systems; exact panel and controller compatibility is subject to confirmation based on installed system model and configuration.
✓ Replacement of flame amplifier modules is a routine maintenance activity in fire alarm and burner control upkeep; correct revision matching is recommended to ensure system compliance and performance.
Marine Applications
✓ Boiler burner management systems aboard tankers, bulk carriers, and container vessels where continuous flame supervision is required.
✓ Incinerator control systems on merchant vessels requiring UV-based flame detection for safe operation and shutdown.
✓ Auxiliary boiler and thermal fluid heater installations on offshore support vessels and platform supply vessels.
✓ Fire detection and suppression control panels in engine rooms and cargo heating systems requiring proven flame signal amplification.
✓ Retrofit and spares replacement programmes for existing Honeywell burner control installations across commercial and naval vessel fleets.
Why Marine Engineers Choose
The Honeywell R7849A1015 UV flame amplifier is a recognised component in burner management and fire detection circuits, valued for its defined temperature tolerance, straightforward replacement process, and compatibility within established Honeywell control architectures — supporting safe, uninterrupted shipboard operations.
Ideal For
