Earlier Alarm, Faster Fire-fighting, Less Loss.
1. Overview
F750/UVIR3 is an ultra-high-speed optical flame detector that can respond quickly (up to milliseconds at the fastest) to conventional hydrocarbon and special non-hydrocarbon flames (such as hydrogen flames, silane flames, etc.) and can capture it instantly In case of danger, a fire alarm signal is issued, and the entire process of fire extinguishing is completed in a very short time, preventing large-scale explosions at the first time and effectively avoiding subsequent hazards.
F750/UVIR3 uses a newly developed high-speed flame dedicated infrared photoelectric sensor and a high-performance ultraviolet photoelectric tube, combined with advanced flame recognition algorithms and 32-bit high-performance processing chips, to achieve rapid flame detection and suppression of false alarm sources. Using this detector can eliminate a large number of false alarm sources and provide reliable and continuous protection in indoor or outdoor environments where multiple false alarm sources exist.

3. Main Features
IR3+UV four-band infrared and ultraviolet composite design: It can detect conventional hydrocarbons and special non-hydrocarbon flames (such as hydrogen flames, silane flames, etc.) at the same time, and has strong anti-interference ability.
Ultra-high-speed alarm: The latest developed infrared photoelectric sensor dedicated to high-speed flames, the fastest alarm time in high-speed mode is less than 1s.
Optical integrity (Oi) detection: Automatic optical integrity (Oi) detection function, real-time monitoring of the working status of the optical path of the detector.
Standard output: Alarm/Fault/auxiliary relay, 4~20mA current loop, RS485 Modbus
Multi-level sensitivity optional: regular type (response time 3-5s) / high-speed type (millisecond response time)
The EMC protection performance is higher than the EMC protection performance required by the national standard GB.
