Difference between Fire Damper and Smoke Damper
Smoke dampers and Fire dampers are an important part of the fire protection system. Smoke dampers are mainly designed and installed in the ductwork and the transfer of air openings prevents the passage of smoke between the sections whereas Fire dampers prevent the spread of fire within the ductwork through fire-resistance-rated walls and floors.
Once the smoke has been detected, the smoke detector sends a signal to the dampers actuator, which uses the jackshaft and linkage to open and close the blades of the smoke damper. Fire damper work when the heat from the fire causes the normal temperature of a room to rise to about 165 degrees Fahrenheit.
