Running cable after the drywall is in ?

The Split Sleeve System™ is a UL Classified retrofit solution designed for sleeving cables which have already been installed without a sleeve and are in violation of the firewall. Installers do not have to pull cable back out of the walls or floors after failing an inspection because of the unique Split Sleeve System design (a threaded, rigid conduit cut in half) which can be fitted around existing, installed cables.

Wouldn't many of the fire caulk, putty pad, and similar systems (reference HILTI) do the same thing for us? I think they would, and that stuff is much more readily available.

Not for a 2-hour rating or greater. A 2-hour rating requires conduit through the penetration and a certain distance to each side of it. I don't have the NEC here with me but I think it is 1' to each side. I'm sure someone will correct me if I'm in error.

The NEC doesn't specifically reference installations installed in rated rated walls and assemblies. Our only section to reference is Section 300.21.

Membrane and Through Penetrations are specified in the Building Codes. Most of us are under some version of the IBC, be it the IBC code iteself or like us in Florida under the FBC which is based on the IBC model. Chapter 7 would be the reference there.

There are many creative products on the market today listed and suitable for use in rated walls and assemblies of all kinds. The UL Fire Resistance Directory is essential to anyone in the construction industry.

California just changed the CBC from being UBC based to IBC based this year. I'm still trying to get caught up.

Not true! There are at least three products on the market now that are not sleeves that will take care of that that I know of that are tested for 2 hour assemblies.

I'm willing to accept that. Got any info?

Default Excellent Information from all..

I should have been more specific. This assembly would only be needed in those instances where the spec calls for all wire to be in conduit or penetration sleeves..I have seen other products that will suffice when a sleeve is not required.

Thanks for all the input.

That's really back peddling. A spec can say anything at all. The spec can say they need to be purple. Some manufacturers of sleeve type products want to dupe us into thinking sleeves are expressly required when penetrating rated assemblies. More responsible companies, such as HILTI, have more cost effective solutions, that when properly applied, accomplish the same job at a lower cost.

In this case, the spec really isn't going to determine the method of penetrating the rating. It's going to be the building codes.

For example, survivability for notification circuits for fire alarm systems require a 2-hour rating throughout per NFPA 72. This usually means Construction Integrity or MI rated cable in conduit whenever a notification circuit leaves a notification zone. The CI cable requires conduit for a 2-hour rating.

For the entire cable, not just the penetration through the wall.

Don't get nasty. I asked earlier if you would provide info on the products that don't require sleeves. If you don't want to provide it, just say so. My google-fu may be weak, but I'm sure I can find it eventually.

Fair enough. I'll look it up amd post it for the benefit of others here that may be interested in it as I am.

I only moderate 2 topics on this forum. Otherwise, I'm a member just like everyone else is here that is interested in gaining new knowledge.

I am curious to see what other products you are talking about. In the past I have always penetrated the fire walls using EMT and fire caulk, but if there is a better product out I am interested in learning about it.

Thanks in advance.

Are we talking about running the cable after walls are up then Firestopping or Firestopping after the cables are in?

Unique Fire Stop Products was (I think) the first to come up with the entire idea and Mike (the owner) has brought a lot of solutions to the industry. Here is a few products you can look at. Let me know if this is what we're talking about.

http://www.uniquefirestop.com/
http://www.abesco.net/
http://www.stifirestop.com/
http://solutions.3m.com/wps/portal/3M/en_US/FP/FireProtection/Products/FirestopSystems/

The best solution will provide:
-create a seal between the two spaces
-pathway for the cables installed now and for future
-bring the fire rating (wall or floor) back to intended rating
-organize or make things easier for identification of cables when needed
-Identification of penetrating items, wires, cables, and their uses
