Product Details

The Fireye TFM-2 is a discontinued Series II flame safeguard amplifier designed for gas, oil and combination fuel industrial burners. This flame safeguard amplifier accepts flame signal from UV scanners or flame rods, executes full ignition sequencing and continuous flame supervision throughout burner operation. As a reliable Series II burner control, it plugs into a dedicated wiring base and integrates fixed timing routines for pre-purge, ignition trial and lockout. This combustion safety module serves as a popular aftermarket replacement spare for older Fireye TFM / UVM legacy combustion systems and is stocked as genuine replacement spare part.

Supported Functions

This amplifier runs the complete burner firing sequence including pre-purge, ignition trial and flame stabilization. If flame fails during operation or no flame is proven within the trial period, it triggers safety lockout and cuts fuel supply immediately. It provides visual status indication for flame presence and lockout faults for on-site diagnosis.

Core Functions

It processes low-level flame sensor pulses and validates real flame against false signals. The plug-in chassis design enables quick swap without reworking field wiring. Built-in timer logic complies with traditional combustion safety codes, and it can serve as direct drop‑in substitution for existing TFM-2 units.
