Definitions

  • the invention relates to a method, a device and a computer program product for designing an aspirative fire detection system.

  • the detector module is used to determine physical or chemical properties of the supplied air samples, so that a conclusion can be made about the physical or chemical state of the room air of the enclosed space.
  • Fig. 1 is shown in a schematic representation of an embodiment of an aspirative fire detection system.
  • a pipe system 102 for sucking air samples through different intake ports is arranged.
  • the pipe system 102 is equipped with a suction detector, in which the air samples from the target area 101 are supplied to a detector module 103 for the detection of fire parameters or for measuring oxygen and other gases.
  • a fan 104 is provided, which serves to suck in the air samples from the target area via the pipe system.
  • the suction power of the fan 104 is adapted to the associated pipe system 102.
