Honeywell FS20X Fire and Flame Detector

Conventional and older technology UV/IR detectors, using

narrow band 4.3 micron IR sensors, will not respond to smoky

fires or if the detector lens is contaminated with oil and

other substances since both UV and 4.3 micron signals are

attenuated, obscured or absorbed by thick smoke or detector

lens contaminations. All UV sensors will be attenuated to some

degree. Also, these old technology UV/IR detectors will not alarm

to any fire if they are installed behind ordinary window glass.

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 whilst 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 FS20X detector has a detection range in excess of 60 m

(200 feet) (very high sensitivity setting) for the detection of a 0.1m2 (one square-foot) Heptane

reference fire and has a cone of vision greater in volumetric coverage than most UV/IR detectors.

This means fewer detectors can be used as compared to other manufacturers’ detectors.

The FS20 detector using advanced patented algorithms for signal processing and fire and flame analysis is

designed to alarm to all types of fires in all industrial environmental conditions. If the detector’s UV signal

is degraded due to heavy smoke or a contaminated lens, the FS20X’s patented WideBand IR™, Near Band

IR and Visible sensors will still alarm to fire, albeit at a reduced sensitivity and slower response time.
