The Fireye 45UV5-1101 is an advanced ultraviolet (UV) flame scanner engineered for critical combustion safety and monitoring in industrial burners, boilers, and process heaters. As part of Honeywell’s Fireye 45UV Series, this detector provides fail-safe flame supervision for gas, oil, or multi-fuel applications by sensing UV radiation emitted during combustion. The Fireye 45UV5-1101 features a rugged stainless steel housing with integrated air purge connections, maintaining optical clarity in high-dust environments like coal-fired plants or cement kilns. Its solid-state design incorporates automatic gain control to compensate for flame signal degradation due to window fouling or aging tubes, while a built-in test function validates system integrity without interrupting operations. With a rapid <4-second response time and SIL 2 compliance, this scanner ensures reliable flame detection for burner management systems (BMS), preventing hazardous fuel accumulation during ignition failures or flameouts.

Main Features and Advantages
Unmatched Combustion Safety: The Fireye 45UV5-1101 utilizes a military-grade UV sensor tube with immunity to solar radiation and artificial light interference. Its dynamic sensitivity adjustment maintains detection reliability despite quartz window contamination, reducing nuisance trips by 90% compared to fixed-gain detectors.
Intelligent Diagnostics: Continuous self-checking monitors sensor health and optical path integrity. A front-panel LED indicates flame presence (green), fault conditions (red), and test mode (yellow). The detector automatically triggers an alarm if sensitivity drops below safe thresholds.
Robust Industrial Design: The stainless steel body withstands direct exposure to 260°C furnace radiation. Dual-compartment electronics separate high-voltage components from control circuits, enhancing reliability. Integrated M18 mounting threads and flexible conduit entries simplify retrofit installations.
Maintenance Optimization: Push-button test mode simulates flame signals to validate the entire detection circuit – from scanner to burner controller – without requiring actual flame. Removable quartz lens allows quick cleaning during outages.
Application Field
The Fireye 45UV5-1101 secures combustion processes across industries:
Power Generation: Flame monitoring in utility boilers (coal, gas, or oil-fired) requiring SIL 2 compliance
Refining: Heater and reformer protection in crude distillation units with high hydrocarbon exposure
Chemical Processing: Ethylene cracker furnace supervision where soot accumulation challenges optical sensors
Pulp & Paper: Recovery boiler flame detection in particulate-heavy environments
Waste-to-Energy: Municipal solid waste incinerators with fluctuating flame signatures
Marine: Main propulsion boiler safety on LNG carriers
