Fireye 4-128-1 Firetron Cell

The Fireye 4-128-1 Firetron Cell is a high-sensitivity cadmium sulfide photocell engineered exclusively for use with the Fireye 48PT1 lead sulfide infrared scanner. Designed for precise flame detection in industrial and commercial burner applications, this component monitors infrared radiation emitted by combustion. The 4-128-1 operates as a resistive element that decreases in resistance upon exposure to infrared energy, providing the primary signal to the flame safeguard control. This replacement cell ensures reliable pilot flame verification and main flame monitoring, preventing hazardous fuel accumulation by facilitating rapid shutdown upon flame failure. As a critical safety component, it requires proper alignment within the scanner housing to maintain optimal signal strength. Routine maintenance of the IR sensor is essential for preventing nuisance shutdowns caused by soot accumulation or thermal degradation in high-temperature environments.

• Optimized Spectral Response: Specifically tuned for the 48PT1 scanner to detect the infrared signatures of gas and oil flames.
• Direct OEM Replacement: Ensures full compatibility with Fireye flame safeguard systems without requiring field recalibration.
• Rugged Construction: Built to withstand the thermal cycling and vibration common in industrial burner vestibules.
• High Sensitivity: Provides quick response times for flame-out detection, enhancing overall system safety.
• Simplified Integration: Features precise form-factor matching for rapid field replacement in existing scanner assemblies.

Is the Fireye 4-128-1 compatible with the 48PT2 scanner?
No, the 4-128-1 cell is engineered strictly for the Fireye 48PT1 infrared scanner. Using it in other scanner models will result in signal mismatch or failure to detect the flame.

How can I tell if my 4-128-1 cell needs replacement?
Technicians should monitor the flame signal strength (DC voltage) at the control programmer. A steady decline in signal, even after cleaning the scanner lens, usually indicates the photocell has reached its end of service life.

Does this cell detect ultraviolet (UV) radiation?
No, this is an infrared (IR) sensor. For UV applications, such as those using the Fireye UV1A or UV8A scanners, a different sensing technology is required.
