Abstract:
1. A method for early detection of fires based on the detection of volatile thermolysis products which are characteristic of the material to be monitored, which are channeled in an ionized state through an electric or magnetic or electro-magnetic field, the resulting time and spatial dependent field strength of which modifies the trajectories of the ions for at least one parameter set in such a manner that positive and/or negative ions of the ionized gas are forced onto pre-determined trajectories and are detected and measuring signals are generated by the detected ions and are stored, comprises the following steps: continuous aspiration of the volatile thermolysis products with the ambient air from an area which is monitored with respect to the formation of a fire, when the aspirating is by a unit comprising a pipe system with aspirating holes; continuous ionization of the aspirated ambient air; continuous analysis of the measuring signals of the ion currents in a signal processing unit for the presence of significant changes; triggering a fire alarm signal if significant changes are found for a predetermined period of time.
