Honeywell FS20X-211-22-4 multi-spectrum and flame detector. Dual IR/UV Detector Copper-Free Aluminum Encl. with (2) 3/4 in. NPT entries, INMETRO.

The FS20X is the latest generation high technology Multi-Spectrum (UV/Dual IR/VIS) Fire and Flame Detector, which is part of the FSX family of advanced technology Electro-Optical Flame Detectors. Based on the foundation of the highly successful and reliable SS4 detector, the FS20X detector represents a quantum leap in integrating Infrared and Ultraviolet sensing technologies. The FS20X is a fire and flame detector with a proven UV solar-blind Sensor.
The FS20X exhibits faster false-alarm free response to fires over a wider temperature range and with a much longer detection range compared to conventional UV/IR detectors.
