NFPA 80 & 105

NFPA 80 governs fire door assemblies and NFPA 105 the smoke and fire dampers that keep a rated barrier intact where doors and ducts pass through it. Both come down to the same field question: is the assembly labeled, complete and free to do its job when it is called on. The inspection observes and documents; a defect closed behind a finish is the one that survives to the next annual.

Adoption varies by jurisdiction. Confirm the edition your authority having jurisdiction enforces before you run a walk against it.

What it covers

  • Labeled fire door assemblies — leaf, frame, hardware and glazing as a listed set
  • Clearances at the door edges and undercut, and the condition of the label itself
  • Self-closing and positive-latching operation of the door
  • Fire and smoke damper installation in rated walls, floors and ducts
  • Damper actuation — fusible links and actuators that release and reseat

What the evidence looks like

  • Photograph the door and damper labels legible; an unlabeled or painted-over assembly is a finding, and the shot is the proof.
  • Edge and undercut clearances shown against a scale in frame rather than called acceptable in a note.
  • Door tested for self-closing and latching from the open position, with the closed-and-latched result documented.
  • Damper access panel located and photographed, and the fusible link or actuator captured so its condition and reseating can be judged.
  • Field modifications — surface-mounted hardware, kick plates, hold-opens — flagged where they fall outside the assembly's listing.

Which edition of NFPA 80 & 105 applies to my project?
Adoption varies by jurisdiction. Confirm the edition your authority having jurisdiction enforces before you run a walk against it.
Which checklists verify work against NFPA 80 & 105?
8 free checklists in the RTI library reference this family. Each is listed on this page with the photo evidence every item needs before it can be submitted.

A standard is only met if the evidence exists

RTI holds the submit button until every mandatory item is answered and the photos are attached, then chains the record so it can be proven untouched later.
