We are currently constructing a new store in Bellevue, WA.  All low voltage cabling has pasted electrical inspection and meets all NEC code.  However, the fire marshall has failed the cabling install in any areas where he sees a bundle of low voltage cable citing International Fire Code 7.06-6 (which Bellevue has adopted).  This states that any cable bundles exceeding 20 cables must be sprinkled or separated from other bundles by 24".  The fire marshall is only enforcing this in areas where the ceiling is not already installed.  The first fire inspector did not cite this code.  Right now we have to reroute the majority of cable on one floor.  This also applies to bundles entering into TR/ER locations.  Has any one else run into this situation?  We are too far along in construction to redesign sprinkler locations.

Are there any other municipalities that have adopted this code?

Thanks,

Elaine Curry

 Hi Elaine, A couple of quick questions for your situation.  Will these areas get a ceiling or will these segments of the ITS cabling be exposed?  Shared below is a link that you might consider viewing.

-Are the cables plenum rated in the areas were the ceiling is not already installed?

-How are the cable bundles supported?

The plenum cables are in bundles that are secured directly to the deck using a Hilti Cable Clamp.  They are in a plenum space with a hard lid ceiling.  Seems as if the Fire Marshall is treating this as a combustible situation even though we are installing a limited combustible product.  Any other information you might have would be helpful.

Good news Elaine,

You most likely won't have to pull back any cable just as long as it's "Plenum Rated."

The city of Bellevue along with the state has adopted the IFC and furthermore Bellevue might be tough on their inspections (with good reasons), but this makes for good construction.

I am actually shocked to find out that your AHJ didn't know "data cables" can be Plenum Rated.

I've heard of this before (when the permit falls to the plumber) as regards to additional sprinklers if and when needed in combustible space.  Although, I believe it's the ITS Installer's responsibility for those submittals (msds) and understanding of their AHJ's code adaptations.

Please send me an email and I will forward all necessary info for the solution to your situation.

Kurt,

I don't know if you will be hearing from Kevin, he hasn't logged into this site since December 2009.
