The IR2 Flame Detector is sensitive to low-frequency, flickering infra-red radiation emitted by flames during combustion. Since it responds to flickering radiation, the IR2 Flame Detector can operate even if the lens is contaminated by a layer of oil, dust, water-vapour or ice. The IR2 Flame Detector is set to respond to low-frequency radiation at 1 to 15Hz (1 to 2.7μm) in order to detect all flickering flames, including those invisible to the naked eye, e.g., those emitted by hydrogen fires. False alarms due to such factors as flickering lighting are avoided by a combination of filters and signal processing techniques.
