1. Seal all penetrations of fire-rated construction using the tested UL system applicable to the construction that was penetrated. This includes all floors, corridor walls, and other assemblies required to be sealed against fire/smoke spread.
2. If any exceptions to the above table are found on-site during construction, the contractor shall contact the NC State communication technologies office to determine the appropriate firestop system to be used.
3. All details are reprinted from the online certifications directory with permission from UNDERWRITERS LABORATORIES, INC. All details are copyright 2019 UNDERWRITERS LABORATORIES, INC.
4. All wire way is to be rigidly supported by a wall or floor assembly to eliminate movement in fire-stopped areas. When anchoring wire way to wall or floor, do not use sheet metal screws, but instead anchor with round head bolts on inside of wire way with nuts on outside of wire way, secure cover with screws on each side. Firestop according to UL details.
