Won-Door, with its rapid closing horizontal sliding fire doors, uses the latest innovations in technology, and works in conjunction with cameras and building security systems, to provide facilities with a new level of protection for occupants. 

At the push of a button, the doors can close the building down within seconds to protect everyone, keeping out all hostile threats.

Fire Protection & Security

Won-Door has been a leader in helping solve complex fire protection and security needs for more than 60 years. With hundreds of thousands of products in schools, hospitals, high-rises, and other landmark structures, Won-Door has helped aid fire marshals and local authorities in solving many multifaceted problems. Protecting from fire and intrusion, while providing needed access and control. 

Because Won-Doors are such an important part of the fire and safety equipment in a building, it is of utmost importance to keep them properly maintained so that they are working at optimum efficiency.

The development of the accordion type, horizontal sliding fire door has had a profound influence on the model code requirements that regulate their use. 

According to NFPA 80 inspection codes:

  • End User is responsible for making sure quarterly inspection & maintenance program is being followed
  • Annually a qualified Individual shall inspect and document inspection. (NFPA80
  • Individuals performing the service shall provide proof of qualifications to the facility prior to performing work
  • Doors are of no value unless they are properly maintained and closed or able to close at the time of fire.

Quarterly maintenance should include the following:

  • Make sure the door properly opens and closes all of the way
  • When it is closed, make sure it fully seals inside the track
  • Test the ‘Push to Open’ button and make sure it fully opens. The door should have a minimum of 36 inches clear when open.
  • When the smoke detectors in alarm, the door should close fully.
  • When closing the door, test the sensor to make sure the door stops. This will prevent the door from hurting anyone
  • While the door is moving open or closed, make sure to check the seals at the bottom, check for tears. This is very important since these seals protect your building from fire!
  • Check all of the components in the back (while the door is pulled away from the wall). Get a ladder and make sure the chain and gears are oiled in the back. Lithium chain oil is what should be used on the chain and gears.
  • Check the battery operation – this must be done quarterly to make sure the door is fully operational.
