These highly sensitive flame detectors can accurately detect low-frequency IR radiation (1 to 15 Hz) that is emitted by flames during combustion. Using two IR sensors, the IR2 responds to different IR wavelengths, discriminating between flames and other radiation sources. Offering a maximum ambient operating temperature of 55°C, IR2 offers users a choice of alarm currents, response times, latching or nonlatching outputs and sensitivity. They also have internal self-test sources that check the detector's operation when used remotely.
