The device has a detector for detecting a fire parameter, at least one feed line (3) with an induction opening (4) and a fan for feeding air to the detector via the line. A rubber-elastic part (1) in the induction opening has an inner film with an opening of smaller diameter, whereby the part is in gas-tight contact with the feed line. An independent claim is also included for a method of cleaning an inventive device. |
