Definitions

  • the present invention relates to a smoke, gas or particle detector, a method for detecting smoke, gas or particles and a smoke, gas or particle detection system. It applies, in particular, to the security of property and people.
  • detection is based on the optical principle of light scattering and / or absorption by smoke, gas or particles.
  • the measurement of these physical phenomena allows the detection of smoke, gas or particles and therefore the presence of a risk nearby.
  • the sample of smoke, gas or particles on which the detection is carried out is passively transported to the detector.
  • the air is set in motion by natural convection, due to temperature differences in the environments to be protected. These air movements are sometimes supplemented by air currents associated with the presence of people or machines.
  • air currents associated with the presence of people or machines.
  • a layer of hot air can form under the ceiling, under the action of the Foal effect, thus preventing the arrival of smoke, gas or particles to the detector, which can make it inoperative.
