Offering the highest immunity to false alarms, the UV / IR2 is designed to accurately detect flickering, low-frequency IR and UV radiation (1 to 15 Hz) that is emitted by flames during combustion. Offering a maximum ambient operating temperature of 55°C, the UV / IR2 detector has a UV sensor and two IR sensors that respond to different IR wavelengths from both the UV and the IR spectrum. False alarms from flickering sunlight, arc welding and lighting are eliminated by a combination of UV and dual IR signal processing techniques.
