UV1A3 Fireye Scanner Tech Sheet

Overview

The Fireye UV1A3 is a compact, miniature ultraviolet flame scanner designed for industrial and commercial burner applications. As a non-self-checking discrete detector, it senses ultraviolet radiation emitted by flames to provide reliable combustion monitoring. The unit features a quartz UV tube filled with ionizing gas and is built to integrate seamlessly with Fireye’s primary flame safeguard and burner management systems. It is known for its durable, rugged construction and high-speed response to flame ignition or failure.

Features

• High-Sensitivity Detection: Utilizes a gas-filled quartz tube to detect UV radiation from oil and gas flames.
• Durable Construction: Housed in a compact design with a 1/2-inch NPT threaded mounting collar for secure installation.
• Integrated Wiring: Equipped with a 3-foot (900mm) flexible conduit rated for Tray Cable – Exposed Run (TC-ER), meeting UL-1569 crush and impact standards.
• System Compatibility: Works with a wide range of Fireye controls, including the M-Series, MicroM, Flame-Monitor, BurnerLogix, and Nexus systems.
• Environmental Resilience: Designed to operate in harsh industrial environments with a wide temperature range and NEMA 4X compliance.
• Low Maintenance: Features a non-replaceable tube and a sealed design, requiring only periodic cleaning of the viewing lens.

Applications

The UV1A3 is ideal for monitoring flames in the following systems:

• Industrial and commercial boilers.
• Furnaces and process heaters.
• HVAC heating systems.
• Burners firing natural gas, propane, or No. 2 light oil.
• Flame safeguard systems where the burner cycles at least once every 24 hours (due to the non-self-checking nature of the tube).
