Despite the panic hardware (not fire exit hardware) installed here, this is a fire door, according to Daniel Davis.
Products installed as part of a fire door assembly must be listed or labeled for that purpose. Components that are not listed or labeled must not be attached to the fire door and may void the label. In two recent cases I have seen non-listed protective guards for hardware as well as blinds installed on fire doors. The AHJ required them to be removed and the holes filled appropriately – with steel fasteners or the same material as the door and frame (there is also a fire door caulk available).
Thanks for the photos, Daniel!
