Flame Detector Addressed or Collective, ASA TechnologyTM

(3 sensors)

The flame detector measures infrared radiation and can therefore detect liquid and gas fires without smoke and organic material fires with smoke. It has three sensors with ASAtechnology and can distinguish between deceptive phenomena and real fires.

  • Pyroelectric sensor A measures the infrared radiation in the characteristic CO2 spectral range between 4.0 and 4.8 µm.
  • Pyroelectric sensor B measures the infrared radiation of deceptive phenomena, such as hot objects, in the range between 5.1 and 6.0 µm.
  • Sensor C is a silicon photo diode and measures solar radiation in the range between 0.7 and 1.1 µm...
  • A sensor measures the hot CO2 at a specific wavelength of the flame; the other two sensors measure interference radiation at other wavelengths at the same time.
  • With the intelligent signal processing using fuzzy algorithms and wavelet analysis, the flame detector achieves excellent detection reliability with maximum immunity to interference emitters and sunlight at the same time.
  • In order to safeguard against a possible decision emergency, the flame detector contains an additional emergency activation channel
