Honeywell Model FS20X Multi-Spectrum Fire and Flame Detector UV/Dual IR/VIS



Honeywell Model FS20X Multi-Spectrum Fire and Flame Detector UV/Dual IR/VIS

Product Overview

FS20X is the latest generation of high-tech multispectral (UV/dual IR/VIS) fire and flame detectors, belonging to the FSX series of advanced technology photoelectric flame detectors. It is based on the highly successful and reliable SS4 detector development, achieving a huge leap in integrating infrared and ultraviolet sensing technologies, and has a validated ultraviolet sun blind sensor. Compared with traditional UV/IR detectors, FS20X responds faster to fires over a wider temperature range without false alarms, and has a longer detection range.

Core Features

Advanced sensing technology: using patented WideBand IR ™  The combination of infrared technology and ultraviolet technology, equipped with visible light sensors to optimize false alarm elimination, and a validated ultraviolet sun blind sensor.

Performance parameters: Detection range exceeding 60 meters (200 feet) (for a 0.1 square meter (1 square foot) heptane reference flame under extremely high sensitivity settings), field of view at a 90 ° horizontal cone (off-axis ± 45 °), selectable detection sensitivity (extremely high (60 meters), high (45 meters), medium (30 meters), low (15 meters)).

Intelligent function: Dual microprocessors ensure high-level fault safe operation and fast and reliable performance; Equipped with a real-time clock that can accurately record event times; FirePic ™  Can store up to 6 pre fire event data; Event logs can record up to 200 events with dates and timestamps.

Communication and output: Built in RS-485 ModBus communication function, non isolated 4-20mA analog output (sink or source), with alarm, fault, and fire verification relays.

Other features: automatic optical path and electronic self-test; The patented electronic module is used for component protection and adopts plug-in termination for easy on-site installation; There are two 25mm conduit inlets or two three-quarters "NPT inlets; Low power consumption, high resistance to radio frequency interference and electromagnetic interference; Obtained multiple certifications such as FM, ATEX/IECEx, INMETRO, CU-TR, etc., meeting SIL 2 requirements, optional certification to EN54-10:2002, with FM 3260 performance.
