Claim 12:
13. A method for fixing a wall or ceiling feedthrough (100) for a suction particle detection system according to claim 1 within a through opening (320) of a wall-like or ceiling-like room structure (310) having a visible side (311) facing toward a test environment (300) and a rear side (312) facing away from the test environment (300), wherein
in a first step, a tube or hose system (210) of the suction particle detection system, arranged on the rear, behind the wall-like or ceiling-like room structure (310),
in a second step following the first step, a hose end (200) of the tube or hose system protruding from the through opening (320) is connected in a fluid-conducting manner to a first line end (111) of a line section (110) of the wall or ceiling feedthrough (100), and
In a third step following the second step, the wall or ceiling feedthrough (100) is fixed by means of a fastening means (120) having one or more springs (121) within the through opening (320), wherein the one or more springs (121) are deflected into a guide position and the line section (110) of the wall or ceiling feedthrough (100) is introduced into the through opening (320), so that the one or more springs (121) are arranged on the rear side (312) of the wall-like or ceiling-like room structure (310), and a collar section (114) arranged on a second line end (112) of the line section (110) is arranged on the visible side (311) of the wall-like or ceiling-like room structure (310), so that a suction opening (113) enclosed by the collar section (114) points in a fluid-conducting manner into the test environment (300),
wherein the wall or ceiling feedthrough (100) is formed as an integral component, at least in one piece with the line section (110), the collar section (114), and the suction opening (113), and wherein
the hose end (200) protruding from the through opening (320) is compressed or bent during the introduction of the line section (110) into the through opening (320).
