The Honeywell FS24X Plus is a flame detector that uses WideBand IR infrared technology to identify hydrocarbon and hydrogen fires promptly and reliably. It can detect fires even in unfavourable weather conditions like rain, fog, and smoke.
The FS24X Plus is designed for use in hazardous locations and holds marine certifications. It is also SIL2-rated, making it ideal for safety instrumented system applications.
