Abstract

See full text

In one or more arrangements, a system is presented for preventing the spread of fire through a conveyor opening in a fire wall. In one or more arrangements, a fire door system is connected to the fire wall and/or conveyor proximate to the conveyor opening. The fire door system includes a door assembly, a door frame assembly, and an actuator. The door frame assembly is connected to the fire wall, covers portions of the opening below the conveyor and between belts of the conveyor, and forms a door opening above the conveyor. The door assembly is configured to move between a closed position, where door assembly covers the door opening, and an open position, where the door assembly at least partially uncovers the door opening. The actuator is configured to cause the door to be moved to the closed position in response to fire.
