A method in a vacuum conveying system, which vacuum conveying system comprises at least one feed point (61, 66), a material conveying pipe (100, 101, 102) which is connected to the feed point (61, 66) and at the other end to a separator element (20) in which the material being conveyed is separated from conveying air, and means (3) for providing a pressure difference in the conveying pipe (100, 101, 102) at least for the time of conveying the material. In the method, conveying air is monitored with at least one fire detector (500) and, based on the detection, the conveying system is affected by isolating the fire to a certain part of the system and/or by diminishing the conditions of burning. The invention also relates to an apparatus.
