HCAi FLSO flagged an existing condition and we are required to provide an approved UL system to move the project forward. EMT conduit was placed into the 2hr concrete deck with CAT-5 cables passing up into a wall above. I cannot find a system to match the (2) installations to the left, which the FLSO found acceptable. Please advise how to firestop to cables within the conduit with an approved UL system
Hello,
Thank you for reaching out to the Hilti Fire Protection Design Team to assist you with your firestop engineering needs.
We do not have a listed system for these exact conditions; however, we can address your application through an Engineering Judgment, which will be a custom detail showing your exact application with the firestop components required to maintain the stated ratings.
