The WideBand IR Infrared technology using high-speed solid-state Quantum sensors 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 albeit 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 Fire Sentry FSX family of detectors feature our 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 which the detector actually sees. A combination of outputs makes the Fire Sentry FS24X a truly versatile detector for today’s demanding industrial requirements.

The Fire Sentry FS24X detector has a detection range greater than 61m (200 feet) (Very High Sensitivity setting) for the detection of a 0.093m2 (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.
