60-2721-2 Fireye Scanner

Overview

The Fireye 60-2721-2 is a replacement scanner electronics assembly designed for the 95IRS2E-1CEX InSight I series flame scanner. It is a microprocessor-based component that utilizes solid-state infrared (IR) sensors to detect flame presence and provide superior discrimination in complex multi-burner environments. As an integrated unit, it houses the sensing, processing, and output electronics necessary to replace the internal assembly of existing hazardous-area housings.

Features

• Solid-state infrared sensor provides accurate detection of infrared radiation from 700 to 1700 nm.
• Integrated amplifier and flame relay eliminate the need for external rack-mounted controllers.
• Eight-character alpha-numeric LED display for real-time monitoring of flame signal and parameters.
• Four-button keypad allows for local configuration and adjustment of sensor gain and thresholds.
• Electronic self-checking technology ensures continuous safety monitoring without mechanical shutters.
• Selectable modulation frequencies (Expanded S2 model features) to optimize discrimination between target and background flames.

Applications

The 60-2721-2 is primarily used as a maintenance and repair component for industrial burner management systems. It is specifically intended for use in 95IRS2E-1CEX housings located in hazardous-area environments (Class I, Div 2). Common applications include monitoring coal-fired and oil-fired flames in large utility boilers, industrial furnaces, and multi-burner combustion systems where precise infrared flame discrimination is required to ensure safe operation.
