Fire doors are intended to protect openings in fire-retardant or fire-resistant walls against the penetration of fire in public places. Fire doors must always be self-closing and must not be held open by wedges or other means so that people escaping from a fire can always open the door manually. These doors are designed to close again safely after people have passed through. The closing can be triggered manually by a nearby button or they can be connected to either a smoke alarm or building management system which will automatically close the doors.
Fire-rated doors combine the convenience of a commercial automatic door with a safe solution in case of fire. Innovative technical solutions keep the door functional when fire breaks out. Fire-rated doors unconditionally shut and offer a high degree of fire protection. With sliding fire-rated doors, a failsafe mechanical system keeps the doors closed, while the option of swing opening provides a safe route for evacuation of people and goods. Single slide or center-parting configurations are available. With fire-rated swinging doors, in the event of a fire emergency, the system powers down, allowing the doors to close and latch. Entry is prevented but personnel can exit by pushing the panic hardware. Fire door systems can be equipped with pass doors including multiple doors to provide means for more people to exit.
Fire doors can be labeled anywhere from 20 minutes to 4 hours. Fire door closing apparatus must be UL listed and labeled, and tested at least every 6 months. Both the door and the door frame are required to meet the guidelines of the testing agency which provides the product listing. The core of the door provides fire protection and can consist of different materials including honeycomb, fiberglass, mineral wool or calcium silicate. The door frame includes the fire or smoke seals, door hardware, and the structure that holds the fire door assembly in place. Together, these components form an assembly, typically called a “doorset” which holds a numerical rating, quantified in hours of resistance to a test fire.
