The safety cover has a channel (3) for supplying air. A potentially fire exposed device (1) is provided at an end of the channel, and a cover element (4). The channel is closed by the cover element, particularly in case of fire at the device. The adjustment of the cover element is activated by a thermomechanical actuator (6). The actuator comprises a memory metal, memory plastic from the group of wax elements as thermal active element.
