The Fire Sentry FS20X is a multi-spectrum (UV/Dual IR/VIS) fire and flame detector. The Fire Sentry FS20X detector represents a leap forward in integrating Infrared and Ultraviolet sensing technology, demonstrating faster false alarm-free response to fires in a range of temperatures. wider range and with a much longer detection range than conventional UV/IR detectors.

The Fire Sentry FS20X detector uses advanced patented algorithms for signal processing and flame and flame analysis designed to alarm all types of fires in all public environmental conditions.
