Inspection and compliance

Fire Doors Only Work If They Work Every Time

A rolling fire door can sit open for years before it is needed. Annual inspection and drop testing are what keep it ready.

  • At minimum, annual inspection and drop testing by a trained, certified fire door assembly technician
  • Keep the opening clear: never block, prop open or store materials under a fire door
  • Repairs with manufacturer parts, and a drop test after every repair or approved modification
  • Janus offers fire door training for dealers and customers, including hands-on drop-test training

Follow NFPA 80 and your Authority Having Jurisdiction for inspection and testing requirements.
