Abstract
Official abstract text for this publication.
A method and device for early detection of fires is based on the detection of volatile thermolysis products which are characteristic of the material to be monitored, ambient air being aspirated from an area to be monitored with respect to fire and being ionized, the ionized gas flow being channeled through an electromagnetic field, the resulting field strength of which modifying the trajectories of the ions in their temporal and spatial dependence with a 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 for generating a fire alarm. Accordingly, fires can be detected quickly and reliably in the earliest possible phase before their full development so that taking or initiating follow-up actions can occur particularly quickly and at an early stage.
First claim
Opening claim text (preview).
What is claimed is: 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 for…
