So what you're saying is that per the I-Codes, hydrants are the preferred method of protection and sprinklers secondary?
When have you ever needed the approval of the AHJ to install sprinklers instead of just providing enough water to hydrants? The trouble is, there is no wording in the IFC stating that the Fire Flow per appendix B is the minimum acceptable provision thus allowing sprinklers to consume less water while you are providing a larger source that assumes no sprinklers.

So in the I-codes Sprinkler = Reduced fire flow requirements or an alternative to full fire flow provisions. Let's say I do a flow test that shows I have 1500 GPM available @ 20 Psi, but the required fire flow for this building and type is 2750 Gpm. What can I do? Provide fire sprinklers of course with AHJ approval. Does that come out of the available fire flow? Of course it does, because I've still only got 1500 Gpm available. It's not added to the minimum fire flow, it's part of the fire flow. Thom McMahon, SET Firetech, Inc. 2560 Copper Ridge Dr P.O.

And yes the fire flow accommodates the demand for both. I'm trying to figure how much storage is needed. _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
