A heat activated sealing apparatus for closing and locking a plurality of ventilation damper blades of a ventilation framework includes a fire detection assembly for detecting a fire condition and an actuator. A damper closure assembly includes an axle in communication with the actuator of the fire detection assembly and operatively coupled to the plurality of dampers of the ventilation framework, the axle being selectively rotatable between a start configuration at which the plurality of ventilation dampers are at the open configuration and a deployed configuration at which the plurality of ventilation dampers are at the closed configuration. The damper closure assembly includes a locking assembly movable between an unlocked configuration allowing rotatable movement of the axle and a locked configuration not allowing rotatable movement of the axle. The locking assembly is movable to the locked configuration only when exposed to a predetermined amount of heat from the fire condition.

A ceiling vent assembly has a frame and a pair of louvers pivotably mounted in the frame such that each of the louvers pivots between an open position and a closed position. Each of the louvers has a pivot end, wherein the pivot end of a first louver of the pair of louvers is located adjacent to but spaced apart from the pivot end of a second louver of the pair of louvers. The ceiling vent has a sealing mechanism positioned in the space between the first and second louvers so as to press on the pivot ends of the first and second louvers such that the sealing mechanism reduces the flow of air through the space. When the first and second louvers pivot between the open and closed positions, the pivot end of the first and second louvers slide relative the sealing mechanism.
