Abstract

A device is indicated for detecting fire in ventilated appliances or machines (1), comprising a measuring chamber (2) through which flows the main current of cooling air or a representative fraction derived from it, and further comprising at least o ne detector (12, 13) arranged in the measuring chamber (2) in the air flow to sense a fire characteristic magnitude and connected to an alarm means, an extinguishing and/or a switch-off device, for example by way of an electronic circuit. It is provided, in accordance with the invention, that the measuring chamber (2) is designed as a chimney having its one cross sectional opening placed on a part cross section of an air outlet (6) of the ventilated appliance or ventilated machine (1) in order thus to shorten the detection time and increase the reliability of detection of a fire in ventilated appliances or machines, such as electronic data processing equipment and similar electronic means. In an alternative embodiment it is provided, according to the invention, that the measuring chamber (2) is designed as a flat box, open at two sides, having one open face end connected to the outlet of an exhaust air channel (14), that the exhaust air channel (14) likewise is of box-shaped design and is placed on the air outlet (6) of the ventilated appliance (1).
