The system further comprises a damper mechanism to substantially block the flow of air through the damper housing when the temperature around the housing reaches a predetermined level. Two or more cross members are included, each of which is mounted between fixed points in the ceiling in a position to allow the cross members to support and hold the damper housing. The damper housing rests on the cross members and is mounted to the cross members. A method for mounting a ceiling damper that comprises providing a ceiling damper having a damper housing for accepting air from a HVAC system and providing the HVAC system air to a room.
