Honeywell R7849B1021 Ultraviolet Rectification Flame Amplifier 2 or 3 SEC FFRT

This Honeywell R7849B1021 Ultraviolet Rectification Flame Amplifier is used to detect light created by combustion in HVAC systems. It generates light that is detected by the amplifier sensor when exposed to a flame. This detected signal informs the control system that a flame establish. This radiation cause flame loss, the amplifier quickly reacts by triggering a shutdown or activating protective mechanisms. Fast-flame design, the system can respond quickly in the absence of a flame, which ensures both safety and efficient system performance.
