With high immunity to false flame sources, both indoors or out, these highly sensitive flame detectors can accurately detect low-frequency IR radiation (1 to 15 Hz) that is emitted by flames during combustion, even under the most difficult conditions. Ideal for indoor or outdoor applications, the IR3 has three sensors that respond to different IR wavelengths, discriminating between flames and other sources of radiation. Offering a maximum ambient operating temperature of 55°C, IR3 offers users a choice of alarm currents, response times, latching or non-latching outputs and sensitivity. They also have internal self-test sources that check the detector's operation when used remotely.
