IU-01

DATA AND FACTS

Infrarot-Ultraviolett-
IR / UV combination flame detector

The IU-01 infrared/ultraviolet combination flame detector detects fires with open flames with the involvement of carbon. The IR part responds to the flickering of the flame and the spectral line of CO2, the UV part to the ultraviolet portion of the flame radiation mainly contained in the flame borders (UV-C radiation in the range 185-235 nm). The alarm is first tripped if both the IR and the UV portion have detected a fire. The device is very suitable for open flames without smoke development.

It does not respond to sunlight, light bulbs (continuous/modulated), fluorescent lights, flying sparks, arcs, hydrogen flames, small flames without flickering, or metal fires. Smoke, dust and water vapor, as well as contamination of the panes on the sensor, ensure application limits, because they absorb radiation and negatively effect the response behavior of the sensor.
