Brief IntroductionIR&UV Flame Detector, which adopts a UV sensor not sensitive to the sunlight and an IR sensor with high signal to noise ratio and narrow band, ensures excellent detection sensitivity with improved immunity from non-fire alarm source (light blindness). Sensors carefully selected in IR/UV flame detector guarantee the high sensitivity to frequency spectrum emitted by the flame. The logic circuit integrated in the UV sensor prevents the false alarm caused by solar radiation.The detector can detect the flame of hydrocarbon such as hydrogen, hydroxy compounds, metal and inorganic matter fire. The detector analyzes the frequency, brightness and duration of the signal received by the UV and IR sensors, and any sensor can trigger alarm when receiving the flame emission spectrum. The detector works in environmental extremes like high/low temperature, high dampness, knock, etc.Characteristics - IR&UV duplex detection and diagnosis- High explosion prevention and dustproof grades- Operation with a wide range of temperature- Detection in a 90 DEG wide cone of vision- Real time self diagnosis function- Electromagnetic radiation immunity - Patented and industrialized contour design - Adjustable sensitivity-Standard current output of 4-20mA, standard RS-485interface, passive contact outputTechnical ParametersBasic Technical Parameters- Spectral response: 185 260nm UV; 1.8 3.2umIR - Fire response time: <10S - Monitoring angle: ≤90°- Ambient temperature: -40°C 70°C - Ambient humidity: ≤95%RH (40 + 2°C) - Detection distance: 25m (0.1 squaremetersstandard normal heptanes fire)Electrical Parameters- Operating voltage: 18V 32VDC- Indication lamp: flash for normality and keep lighting for alarm- Operating current: ≤20mA (24VDC) in a standby status ≤35mA (24VDC) in an alarm status- Output mode: relay output--------for normally: the contacts of the fault relay are normally closed. While the contacts of fire alarm relay are normally open. For fault: the contacts of the fault relay become normally open from the normally closed status For alarm: the contacts of the fire alarm relay become normally closed from the normally open status Capacity of contact: 0.5A /125VAC 1A /30VDC 0.3A/ 60VDC 4-20mA Output-------For fault: 0+0.5mAnormally: 5 mA±10% early warning: 12mA±10%fire alarm: 18mA±10% RS-485 Output------- RS-485 standard interface for being connected with equipments like controllerMechanical Characteristics - Cable outlet screw: standard 3-G3/4"(1"=25.4mm) - External dimensions: 147mm×145mm×233mm (length × width × height)- Material: cast aluminum with stainless steel optional- Weight: <1.7kg (cast aluminum) < 3.2kg (stainless steel)Certifications- Explosion prevention mark: ExdIICT6 - Dust flameproof mark: DIP A21 TA,T6- Protective grade: IP65 - Mode inspection: In accordance with national standards of GB15631-1995 and GB12791-2005- Executive standards: GB15631-1995, GB12791-2006, GB3836.1-2000, GB3836.2-2000, GB12476.1-2000Applications- Chemicals --- production, storage and transportation- Electricity generation--- pump zones, machine rooms and unmanned zones - Printing ---solvent treating, flattening and drying techniques- Aerospace --- hydroxide, hydrazine and hydrogen fuel - Auto --- fabrication, paint spray booth - Paints --- manufacture- Warehouse--- storage of combustibles - Petrochemicals ---production, storage and transportation - Explosive and munitions---storage, loading and unloading - Rubber industry---manufacture and composition - Hangar - Pharmacy
