Conventional and older technology UV/IR detectors, using narrow band

4.3 micron IR sensors, will not always 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.

Superior Technology Dual microprocessors enable fast and reliable performance.

The master microprocessor performs high-speed digital sampling

and signal processing calculations while the slave microprocessor handles sensor data,

performs communications, self-diagnostics and manages interfaces and 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 field of view with a greater volumetric

coverage than most UV/IR detectors.
