FD1020 FD1020 Dual Infrared Flame Detector

Description

The Xinhaosi FD1020 Dual Infrared Flame Detector is an intelligent fire detection device built with high-performance multi-wavelength infrared sensing technology. Using dual-band narrow filtering and advanced flicker-analysis algorithms, it isolates genuine flame spectrums while actively filtering out sunlight, lightning, welding, and thermal radiation interference.🌟 Key HighlightsAdvanced Multi-IR Sensing: Deploys narrow-band filters to cross-examine core flame wavelengths against ambient infrared noise.Long-Range Reach: Accurately senses a standard 0.3m × 0.3m n-heptane flame from up to 50 meters away.Precise Field of View: Protects industrial zones with a reliable 90° detection angle.No-Cap Sensitivity Control: Employs an external magnetic rod system to adjust 4 sensitivity levels without opening the enclosure.Harsh-Environment Ready: Features a copper-free cast aluminum shell with an epoxy finish, IP66 ingress protection, and dual gas/dust explosion-proof ratings.📊 Quick SpecificationsSpectral Range: 4.3μm and 5.0μm infrared wavelengthsResponse Speed: Shuts off and registers alarms in ≤ 10 secondsOutput Capabilities: 4–20mA current loop, 1 passive fault relay, and 1 passive alarm relay.Supply Voltage: DC 24V ± 6V (≤30mA operating current)
