Abstract

A device for detecting fires in forcibly ventilated devices or machines (14) is disclosed, which device has an outlet air funnel (1) which removes a representative partial amount from the main stream of cooling air at the air outlet (15) of the device (14) to be monitored and feeds the said amount via an air line (6) to a measuring chamber (5), and which device has at least one detector for detecting a fire characteristic variable, which detector is arranged in the measuring chamber (5) in the air stream and is connected for example by means of an electronic circuit to a warning, extinguishing and/or switch-off device. In order to shorten the detection time in forcibly ventilated devices or machines, for example EDP devices or similar electronic devices as well as to increase the reliability of fire detection, there is provision according to the invention for the wall (2) of the outlet air funnel (1) to have openings (3) distributed over its circumference. By means of the outlet air funnel (1) which is designed in this way, eddies and back-pressure of the air within the outlet air funnel (1) are avoided and it is ensured that the partial amount of air which is tapped off from the main stream of cooling air is fed to the hose (6) as an air stream which is as far as possible laminar. <IMAGE>
