95IRS2-2 Fireye Scanner

Overview

The Fireye 95IRS2-2 is a microprocessor-based, integrated infrared flame scanner designed for industrial burner management and flame safeguard applications. As part of the InSight I (95 Series) family, this “Enhanced” (S2) model is specifically designed for fiber-optic mounting, allowing for flame detection in environments where a direct line-of-sight is obstructed or where high temperatures require the electronics to be remote from the burner front. It combines both the sensor and amplifier into a single unit, providing a direct flame relay output and eliminating the need for remote rack-mounted amplifiers.

Features

• Infrared (IR) sensing technology optimized for monitoring coal and oil-fired flames.
• Fiber-optic compatible design for flexible installation in complex burner geometries.
• Integrated flame and fault relays with adjustable ON/OFF thresholds.
• Electronic self-checking system that eliminates the need for a mechanical shutter.
• Eight-character alpha-numeric LED display and four-button keypad for local monitoring and configuration.
• Enhanced “S2” features including automatic programming (autotune), manual override, and 21 selectable modulation frequencies for superior flame discrimination.
• Rugged NEMA 4X / IP66 housing suitable for hazardous locations (Class I, Div 2).

Specifications

• Model Number: 95IRS2-2
• Input Power: 24 Vdc (+10%, -15%), 0.35A
• Output Relays: Flame (SPST N.O.) and Fault (SPST N.C.)
• Analog Output: 4-20mA dc current for signal strength monitoring.
• Electrical Connection: 12-pin quarter-turn quick-disconnect.
• Temperature Rating: -40 degrees F to +150 degrees F (-40 degrees C to +65 degrees C).
• Humidity: 0% to 95% relative humidity, non-condensing.
• Cooling/Purge Air: Requires clean, dry air (typically 4-15 SCFM depending on application).
• Approvals: FM and CSA approved.

Applications

The 95IRS2-2 is primarily used in industrial and utility power plant applications for monitoring burners fired with coal or heavy oil. Its fiber-optic capability makes it ideal for tilting tangential-fired boilers, package boilers with obstructed sight paths, and installations where the scanner must be protected from high ambient temperatures near the burner windbox. It is commonly applied in multi-burner environments where precise discrimination between the target flame and background radiation is required.
