Fire dampers are designed for the purpose of preventing the spread of flames across a rated barrier. A fire damper is installed within the duct where the duct intersects the barrier. They operate using a heat sensitive device that, when activated, melts and causes the damper components to close. Fire Damper can also be controlled by electrical device which is an actuator. Hence, we call it Motorized Fire Damper.
