Nohmi's infrared three-wavelength ﬂame detector (PDCJ002-E) is designed to detect the presence of ﬁre from the radiant energy produced byﬂames (CO2 resonance radiation) and ﬂame ﬂicker. The PDCJ002-E quickly detects ﬁre even in places with ventilation ﬂow, external air, or high

ceilings where detection is often diﬃcult for the ordinary detectors. This high-sensitivity detector is suitable not only for large spaces but also0°

for outdoor facilities.

2. Reliable ﬁre detection

The PDCJ002-E detects the CO 2 resonance radiation and flicker that are uniquecharacteristics of flames. Despite its high sensitivity, the PDCJ002-E has fewer
false alarm performance and can be installed under direct sunlight or artificial
lighting such as sodium lamp, mercury lamp, fluorescent lamp, germicidal lamp,
halogen lamp, etc.

Plants, designated combustible warehouses,
large space such as atrium, forests and etc.

The energy intensity of the three wavelength bands in the CO2 resonance radiation band andthe ﬂicker of the ﬂame are judged as “ﬁre” by an advanced algorithm to suppress false alarms.

3456■：The red band is the wavelength band detected.

The infrared energy emitted from ﬂames has the spectral characteristics of a peak in
the wavelength of the 4.4μm band. This is called CO2 resonance radiation. As shown
above, this feature is quite diﬀerent from the spectral characteristics of infrared rays
emitted by objects other than ﬂames.
Another characteristic is that the infrared energy emitted by the ﬂame ﬂickers at afrequency of 1 to 15 Hz. Furthermore, the respiratory action of the ﬂame always
causes ﬂuctuation of the amount of radiation.
Nohmi's infrared three-wavelength ﬂame detector monitors the three wavelength
bands of CO2 resonance radiation. It is able to accurately detect ﬁre by recognising
the unique property of ﬂames in terms of their energy intensity, ratio, etc, CO2
resonance and ﬂicker.
