Description of FDCJ004-D

  • Nohmi’s infrared three-wavelength flame detector (FDCJ004-D) captures the radiant energy (CO₂ resonance radiation) from the flame and the flicker of the flame that occur when an object burns.
    The FDCJ004-D quickly detects fire even in places with ventilation flow, external air, or high ceilings where detection is often difficult for ordinary detectors.
  • This high-sensitivity detector is suitable not only for indoor large spaces but also for outdoor facilities.
  • Despite its high sensitivity, the FDCJ004-D has fewer false alarm performances and can be installed under direct sunlight or artificial lighting such as sodium lamp, mercury lamp, fluorescent lamp, germicidal lamp, halogen lamp, etc.
    The FDCJ004-D has the automatic testing function to periodically check the contamination rate of the light receiving window and the fire detection function.
