Disclosed is a fire door system. The fire door system comprises: a body unit mounted on a lower portion of a fire door in a longitudinal direction, provided with a space formed therein, and opened downwards; a blocking member embedded in the body unit in the longitudinal direction and provided with a magnetic body; a first magnetic force member embedded in the body unit and positioned on an upper portion of the blocking member; and a second magnetic force member embedded in a floor surface on a position corresponding to the lower portion of the fire door if the fire door closed. The first magnetic force member has a larger magnetic force than the weight of the blocking member. The second magnetic force member downwardly pulls the blocking member moved upwards by the first magnetic force member if the fire door is closed to secure an enough magnetic force to tightly attach the blocking member to the floor surface. |
