IR UV Flame Detector Explosion-proof Fire Alarm

The KF715/UVIR2 point type infrared and ultraviolet flame detectors use a new type of photoelectric infrared sensor, combined with flame recognition algorithm and 32-bit high-performance processing chip, which can achieve fast flame detection and suppress false alarm sources. It can provide reliable and continuous protection in indoor or outdoor environments where multiple false alarm sources exist.
The perfect algorithm best combines flame detection and false alarm capabilities;
The detector is suitable for various fuels;
Suitable for heavy industry applications;
Low maintenance cost, easy to update and improve

Optical Window White Gemstone (Al2O3)
Shell material: Aluminum alloy
Molding process: Die casting
Coating process: surface electrostatic powder spraying, internal metal passivation treatment.
Weight ≤ 1kg
Explosion proof and protection: EXd Ⅱ CT6
Protection: IP66

Power supply: minimum 18VDC standard 24VDC maximum 30VDC
Working current monitoring status ≤ 15mA, alarm status ≤ 35mA
Preheating time: 60s after power on
When flames are detected in the monitored area, the detector enters the fire alarm state;
The fire alarm output relay is activated, and the red fire alarm indicator light is on;
When abnormalities are detected in sensors, power supplies, etc., the detector enters a fault alarm state;
Fault output relay action, yellow fault indicator light on;
When a fire alarm and malfunction occur simultaneously, the fire alarm takes priority;
Alarm threshold adjustable at levels 1-3 (set through electromagnetic rod)
The number of green flashes per monitoring status indicates the alarm threshold
Alarm delay adjustable from 0-30 seconds (factory set to 0 seconds)
Combination mode of drift compensation sensor hardware compensation and intelligent software compensation
Can effectively compensate for drift caused by temperature, environmental changes, and long-term operation of components
Interference source suppression can effectively suppress the influence of non flame interference sources, such as sunlight (direct and reflected), commonly used artificial light sources, background radiation sources, hot moving objects, welding, etc
Indicator light l monitoring status: green light flashing
Fire alarm status: Red light constantly on
Fault status: The yellow light is constantly on
Output fire alarm relay, activated upon alarm, output contacts 3A@30VDC
3A@250VAC
L Fault relay, activated in case of fault, output contact 3A@30VDC 3A@250VAC
