Honeywell  FS24X Flame Detector is a Multi-Spectrum Triple IR (IR/IR/IR/Visible) Flame Detector, deploying WideBand Infrared, WideBand 4.3 micron IR and Visible detection technology. Dual microprocessors and advanced software provide optimum detection performance and false alarm minimisation.

On high sensitivity configuration detection range is over 60 meters (200 feet). A user can switch sensitivity as required, high 150 feet, medium 100 feet and small 50 feet. Ideal for all types of fire, hydrocarbon and non hydrocarbon fires.  Wide band IR sensors will still detect fire even if the signal is blocked by glass (reaction time will be increased).

The Fire Sentry FS24X Flame Detector has two field view models, FS24X-211 series with 110° field of view and FS24X-911 Series with 90° field of view. The QuadBand  IR3+ detector is divided into Copper-Free Aluminum or 316 Stainless Steel enclosures. Choose approval required (determined by location and application).

Kit versions are available which include a FSX-A014R HART Module. Range FS24X-212 for 110° field view and range FS24X-912 for 90° field view.
