45RM1-1001 Fireye Scanner

Overview

The Fireye 45RM1-1001 is a specialized infrared (IR) self-checking flame scanner designed for the reliable detection of flames from fuels that are often difficult to monitor, such as oil and coal. It is engineered for industrial and utility burner applications, providing high discrimination between the target flame and background radiation. Although this specific model has been discontinued and replaced by the 45RM4-1001 or 95IRS2-1, it remains a critical component in many legacy flame safeguard systems.

Features

• Infrared (IR) sensing technology optimized for oil, coal, and other hard-to-see fuels.
• Self-checking circuitry to ensure the scanner and signal circuits are functioning correctly.
• Background Gain Control (BGC) to improve flame discrimination in multi-burner environments.
• Compatibility with fiber optic light guides for high-temperature or physically obstructed applications.
• Die-cast aluminum housing for durability in harsh industrial environments.

Specifications

• Model Number: 45RM1-1001
• Sensing Method: Infrared (IR)
• Mounting: 1 inch NPT
• Operating Voltage: Powered by compatible Fireye control (typically 24 VDC or 120/230 VAC via amplifier)
• Frequency: 50/60 Hz
• FFRT (Flame Failure Response Time): Determined by the associated amplifier, typically 2 to 4 seconds
• Housing: Die-cast aluminum with high-temperature gaskets

Applications

The 45RM1-1001 is used in conjunction with Fireye 25SU3 and 25SU5 flame safeguard controls, as well as D-Series, Flame-Monitor, and Flame-worx systems. It is ideally suited for monitoring individual burner flames within large boilers or utility furnaces where multi-fuel firing (such as coal or oil) occurs. Its ability to work with fiber optic assemblies makes it essential for applications where the scanner cannot be mounted in a direct line-of-sight to the flame.
