This is an online training for the FS24X Plus. This is the newest member of Honeywell’s FSX series of advanced, multi-spectrum, electro-optical flame detectors, providing high performance in challenging conditions. The Honeywell FS24X Plus uses our WideBand IR™ infrared technology to quickly and reliably detect hydrocarbon and hydrogen fires — before they grow — even in the presence of environmental inhibitors like rain, fog, and smoke.
