Infrared Three-Wavelength Flame Detector
Note:This diagram shows the monitoring
distance of a flame in a normal
heptane fire tray from several angles.
The monitoring distance varies
depending on the type, size, and
form of combusbles.
The PDCJ002-E detects the CO2resonance radiation and flicker that are unique
characteristics 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.
The infrared energy emied from flames has the spectral characteriscs of a peak in
the wavelength of the 4.4μm band. This is called CO2 resonance radiaon. As shown
above, this feature is quite different from the spectral characteriscs of infrared rays
emied by objects other than flames.
Another characterisc is that the infrared energy emied by the flame flickers at a
frequency of 1 to 15 Hz. Furthermore, the respiratory acon of the flame always
causes fluctuaon of the amount of radiaon.
Nohmi's infrared three-wavelength flame detector monitors the three wavelength
bands of CO2 resonance radiaon. It is able to accurately detect fire by recognising
the unique property of flames in terms of their energy intensity, rao, etc, CO2
resonance and flicker.

Detecon wavelength band of the infrared three-wavelength flame detector
Nohmi's infrared three-wavelength flame detector (PDCJ002-E) is designed to detect the presence of fire from the radiant energy produced by
flames (CO
2
resonance radiaon) and flame flicker. The PDCJ002-E quickly detects fire even in places with venlaon flow, external air, or high
ceilings where detecon is oen difficult for the ordinary detectors. This high-sensivity detector is suitable not only for large spaces but also
for outdoor facilies.
Features
High sensitivity
Catches the flame of 33 cm2 normal heptane fire tray at a distance of 60 m. (It is also possible to
detect flames more than 60m away depending on the scale of the flame.)
Reliable fire detection
The energy intensity of the three wavelength bands in the CO2 resonance radiaon band and
the flicker of the flame are judged as “fire” by an advanced algorithm to suppress false alarms.
Equipped with self-diagnosis function
The internal circuit is constantly checked, and if an error occurs, a trouble signal is transmied.
The contaminaon of the light-receiving window is also automacally checked.
