Asenware AW-FD707EX Exproof Ultraviolet + Infrared (⟦0⟧/⟦1⟧) Flame Detector

AW-FD707EX is a conventional flame detector with explosive atmosphere protection that evaluates ultraviolet band together with two separate infrared bands, detecting flame up to 40 meters distance. Dual ⟦2⟧ channel filters out false signals from hot surfaces and artificial light sources; response time to real flame is less than 10 seconds. Its Ex d IIC T6 Gb / tD A21 protected housing is classified as ⟦0⟧/⟦1⟧ and operates between -40°C and +70°C, making it suitable for positioning in fuel filling areas, paint booths, gas stations, and open process areas. Power supply is DC 24V (18-30V) and the device is connected to the conventional fire detection panel line. It should not be confused with the manufacturer's similarly named AW-FD704EX model: that product is four-spectrum with 60 meter range, whereas this device features ⟦3⟧ + dual ⟦4⟧ (UVIR2) structure.
