Fireye 60-2207-2 Module 322027-701 If the 69M77 ballast isThe Fireye 60 2207 2 is a professional grade high discrimination flame amplifier module specifically designed for industrial combustion environments where background radiation is a factor. As a flame safeguard control component, this module effectively filters out interference from adjacent burner flames or hot refractory surfaces, ensuring that only the specific monitored flame triggers the flame relay. This level of precision is critical for multi
