This invention is a protector for smoke detectors that can be mounted in atmospheres that have heavy airborne pollution that would normally cause a detector to malfunction. The protector is an enclosure including automated means for opening and closing the door for the Smoke Detector Protector that is relatively airtight when closed to prevent the ambient airborne particles from entering the same. Once the heavy concentration of airborne pollutants caused by manufacturing operations, etc. have been adequately reduced to a level that malfunctioning will not occur, such as when the manufacturing operations have ceased, then the enclosure will be opened to expose the enclosed smoke detector to the ambient atmosphere. Should a fire then occur, the smoke therefrom could be readily detected, and through the normal operation of the smoke detector, an alarm can be signalled.
