FS24X Flame Detector Triple IR

The FS24X Flame Detector Tripe IR is the latest generation high technology Multi-Spectrum Triple IR (IR/IR/IR/Visible) Flame Detector, which is part of our FSX family of advanced technology Electro-Optical fire detectors. Using patented WideBand IR, WideBand 4.3 micron IR, and Visible detection technology, the FS24X is a quantum leap in flame detection.

Sophisticated software algorithms and dual microprocessors ensure that the FS24X has the highest fire detection performance combined with optimal false alarm rejection. The WideBand IR Infrared technology uses high-speed solid-state Quantum sensors, and this allows detection of all types of fires, hydrocarbon and non-hydrocarbon, in all weather conditions.

If the detector’s signal is blocked by ordinary window glass, the patented WideBand IR sensors will still alarm to the fire but at a reduced sensitivity and slower response time. Dual microprocessors provide a high level of fail-safe operation combined with fast and reliable performance. The Master Microprocessor performs high-speed digital sampling and signal-processing calculations; while the slave microprocessor handles various sensor data, performs communications, self-diagnostics and provides interface versatility; and additional memory for storing Event Log and FirePic data.

The FSX family of detectors feature patented FirePic data storage and information retrieval facility. FirePic records pre-fire data, which can be recovered from the Detector’s non-volatile flash memory for post fire analysis and postulation of the fire cause. Additionally, unique Real-Time Graphing (RTG) allows viewing of the data that the Detector actually sees. A combination of outputs makes the FS24X a truly versatile detector for today’s demanding industrial requirements.

The FS24X Flame Detector has a detection range greater than 200 feet (Very High Sensitivity setting) for the detection of a one square-foot Heptane reference fire and has a cone of vision far greater in volumetric coverage than any other Multi-Spectrum IR Detector. This means fewer detectors can be used as compared to other manufacturers’ detectors.
