GW820UVIR3
The GW820UVIR3 detector represents a significant leap in the integration of infrared and ultraviolet sensing
technologies.The GW820UVIR3 detector is a multispectral,UV/three infrared,and flame detector.Compared to
traditional UV/IR detectors,the GW820UVIR3 offers faster response time,fewer false alarms,a wider operating
temperature range,and longer detection distances
Most traditional IR3 detectors only use narrowband 4.3-micron infrared sensors,which can
only detect combustion for Class CH fires and cannot detect flames from materials such as
metals,hydrogen gas,and silane.The GW820UVIR3 detector can address the detection of
such substances.
Superior Technology:Dual microprocessors enable fast and reliable performance.The main microprocessor
handles high-speed digital sampling and signal processing calculations,while the subordinate
microprocessor processes sensor data,performs communication,and self-diagnosis.The GW820UVIR3
detector has a detection range of over 60 meters(200 feet)when detecting a 0.1-square-meter (one square
foot)heptane reference fire (with highly sensitive settings),and its field of view coverage is larger than most
UV/IR detectors.This means that fewer detectors can be used to cover an area compared to detectors from
other manufacturers.
The GW820UVIR3 detector employs artificial intelligence software,providing robust system stability.It utilizes
FFT algorithms and neural network algorithms(industry-leading self-learning and trend analysis algorithms)
and possesses the capability of environmental self-learning and adaptive compensation algorithms.It has
undergone extensive network testing with a large number of detectors,as well as rigorous system
strengthening tests under various environmental factors and frequencies.This ensures a safe and reliable
solution for industrial large-space environments.
