You could probably get there in a roundabout way. Such as Section 907.2.12
requires a high rise building to be provided with an automatic fire alarm
system and emergency voice / alarm communication system. The emergency voice /
alarm communication system requires a general alarm or stage
Section 3-1.4 of UFC3-600-1 is for the Total Water Demand for Sprinklered
Occupancies. The total water demand for sprinklered occupancies is equal to
the sum of the domestic/industrial demand plus the sprinkler system(s) water
demand and the hose stream(s) demand. The total demand must be
FM Global does have requirements on the friction loss equations that are to be
used when the velocity exceeds a certain criteria. For FM systems, the use of
Darcy-Weisbach is required if the velocity exceeds 30 ft/s; otherwise
Hazen-Williams is the acceptable method for anything below 30 ft/s.
There is a federal mandate out there that restricts the velocity of the water
at the suction point. This is supposedly due to a kid being drowned by such an
incident. In the past we had to create multiple suction points that tie back
into the single supply pipe to get the velocities down to

The following two definitions are contained within the FM Data Sheets. As far
as I know, the reasoning behind the 32 fps restriction was that it equates to
the difference between turbulent and laminar flow of fluids (in this case
water) through a piping network. The accuracy of the Hazen

There are a few design directions the project may go. One option is to
identify it as a separated mixed-use building, which requires fire-rated
separations between occupancy types and incidental use areas. A second
option is non-separated mixed use where the architect / engineer need to

I know that I should be able to find this, but I am having trouble
locating a section in NFPA 13 (2002 or 2007 Editions) that states the
temperature ratings of sprinklers are required to be the same throughout
the protected space unless the items listed in Section 8.3.2.5 apply.

As an individual who has performed plan reviews for the company recently
being discussed on this forum (and will be gaining PE licensure this
year), I have to respectfully disagree that all we do is put fluff and

Steve,
We like to look at the different manufacturers and have their
engineering department make the engineering judgments when there is not
a known rated assembly. Examples of these are Hilti and 3M.

From what we have experienced, the intent of the horizontal exit is to
be supplemental to the stairs and other egress components. However, as
currently done the horizontal exit also acts as an audible zone

I have a question for the group. If you have an object in the

There are some changes to the 2006 IBC sprinkler requirements. They
