Re: Hose Stream Demand Residential

2017-08-08 Thread Roland Huggins 
Actually the A.7.2 explicitly states that for areas outside dwelling unit that 
must apply full 13 design factors, a hose stream is not required.

Re: Hose Stream Demand Residential

2016 ed.
A.7.2 It is only the intent of NFPA 13R to reference the sprinkler
discharge (flow and pressure), number of design sprinklers,
and position of sprinklers (distance from walls, ceilings,
and other sprinklers) requirements of NFPA 13. Other rules
from NFPA 13 such as sprinklering of combustible concealed
spaces, hose stream demand, and water supply duration are
not intended to be referenced by Section 7.2. It is also the
intent of Section 7.2 to apply to those systems or portions of
systems that are outside the dwelling unit but have been determined
to be considered residential, accessory, or incidental to
residential and within the scope of this standard.

It used to be clear in 2002 but I have not been able to find it in more recent 
editions.

I'm going off of memory - which seems to be slipping as I age - but I don't 
believe NFPA 13R has a hose stream requirement.  However, be cautious of that 
domestic demand.  Maybe I get conservative, but if I have a complex with 
several buildings on a site water line, I add the domestic demand to the site 
water loop.  That has been in excess of a hose allowance many times.

Does NFPA 13R require a hose stream demand? Section A.7.2 of NFPA 13R only 
reference a hose stream demand requirement of NFPA 13. The only additional 
demand required in a calculation is the domestic demand if there is a common 
domestic/fire main as referenced in section 9.6 of NFPA 13R.
