A fire damper and a fire smoke damper are two different types of dampers that are used in buildings to help protect against the spread of fire and smoke. A fire damper is a device that is installed in the ductwork of a building and is designed to close off the duct when a fire is detected. This helps to contain the fire and prevent it from spreading throughout the building. A fire smoke damper is also installed in the ductwork of a building, but its purpose is to prevent the spread of smoke in the event of a fire. This type of damper is designed to open and close automatically in order to allow the smoke to escape and to keep it from entering other parts of the building. Both types of dampers are essential components of any building’s fire safety system and are designed to help protect occupants from the spread of fire and smoke.
