Abstract (en)
[origin: WO02095703A2] The invention relates to a device for detecting and locating fire sources or gas impurities in one or several monitoring chambers. Said device comprises a (main) detector for detecting a fire characteristic value or a gas impurity, into which a part of the ambient air in said monitoring chambers is continuously injected by means of an intake unit through a line, arranged in each monitoring chamber and provided with intake ports. Said invention also relates to a method for individually detecting fire sources or gas impurities. The aim of the invention is to provide a device and a method, which combine, in a simple and economic manner, the advantages of gas inlet systems, such as an active intake and a concealed assembly, with the advantage of the localization of each intake port as well as the detection of a precise fire source or a precise gas impurity. To this end, said device is provided with a sub-detector, arranged on or in the area of at least one intake port per monitoring chamber, for detecting a fire characteristic value or a gas impurity, said sub-detector being switched on by a switch-on signal transmitted by a controller according to a detection signal delivered by said main detector and said method may be implemented using said device.
