Brief IntroductionThe IR & 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). The carefully selected sensors of the IR&UV flame detector guarantee the high sensitivity to the emission spectrum produced 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 -High explosion prevention and dustproof grade -Operation with a wide range of temperature -Detection in a 90 DEG wide taper zone -Real-time self-diagnosis function -Immunity from electromagnetic radiation -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 percents RH(40 + 2°C) -Detection Distance: 25m(0.1 square metersstandard normal heptane fire)Electrical Parameters-Operating Voltage: 18V 32VDC -Indicator Lamp: flash for normality and keep lighting for alarm - Operating Current: ≤20mA in a standby status (24VDC)≤40mA (24VDC)in an alarm status -Output Mode: relay output--------for normality: the contacts of the fault relay are normally closed,while the contacts of the 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 Rating of contact: 0.5A /125VAC 1A /30VDC 0.3A/ 60VDC 4-20mA Output-------For Fault: 0+0.5mA For Normality: 5 mA±10 percents. For Early Warning: 12mA±10 percents.For Fire Alarm: 18mA±10 percents.
