Sprinklers on Branch Line

[tmurray]

Hello all,

I'm review and updating a course for our local building officials association and have run into a problem. The test asks what the maximum number of sprinklers per branch line is. The old test said there was a maximum of 8 based on clause 14.5.2.1.1 of NFPA 13-2002. I'm updating the code references and cannot find similar provisions in the 2007. Any help would be appreciated.

Thanks,

Trevor

That would have to be in the pipe schedule system section, hydraulically calculated may have many especially gridded systems see 22.5.2.1 for the 8 requirement and the exceptions in 2007 NFPA 13

Thanks frank. I knew the rule, but could not find it.

Thanks frank. I knew the rule, but could not find it.

Do you allow new pipe schedule systems up North?

I've seen more hydraulic design systems, but we do have some pipe schedule method systems.
