Low voltage wiring passes through an electrical metallic tubing conduit with bushed ends set inside a rated partition assembly. Approved non-PVC cables run through the interior with fire seal applied using approved caulk or putty by the cable installer. Penetrations of pre-rated construction receive an approved listed through-penetration firestop system extending twelve inches minimum on each side. This detail is typical for all low voltage wiring penetrations.
