I am a member of NFPA . what exactly are you looking for? the tag itself? or what rating the firedoor should have in that fire wall or smoke wall?
Notes on Fire Door Requirements
-
Fire rated door assemblies require a labeled door, a labeled frame, a listed lock device, listed closing device, and steel bearing hinges. Non-steel bearing hinges are acceptable as tested on listed assemblies.
-
In general, the required hourly rating of the door assembly is 3/4 of the hourly rating of the wall it is being installed into.
-
The minimum rating of any component in the assembly determines the achieved rating as the assembly: a 1 1/2 hour door installed into a 20-minute frame results in a 20-minute assembly.
-
Subdivision of non-rated components or devices in the door assembly can only result in a reduction in or a voiding of the overall fire protection rating.
-
Most fire door installations are governed by NFPA 80- Fire Doors and Windows.
