A-ha! What Roland said. If you think about it, putting that in there in the first place didn't make sense. If we don't have to consider sprinklers and standpipes concurrently in sizing the water supply capacity, why would we calculate them that way? It's not congruent. Once the Class I standpipe is put to use, the functionality of the sprinkler system becomes secondary to the firefighting operation and the safety of responders. Plus, you've got another water supply connected through the FDC so the automatic one on which the calc's were based isn't the only criterion after that.

Doesn't it appear to require inside hose allowance to be added to the sprinkler demand at the point of connection? Tony -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Roland Huggins Sent: April 8, 2010 2:39 PM To: [email protected] Subject: Re: Water Supply WHat does the presence of the 2-1/2 have to do with this issue (unless you are supply the standpipe supply per 14)? The sprinkler calc does not include an inside hose demand for hose connections on a standpipe.
