Pete,
I certainly agree, which is why I was delighted to see that the 15
second delivery time was present in the earlier edition, so it was
applicable under that standard as well.

Even though an earlier edition governs, standard of care from a
liability issue would dictate not ignoring the 15 second requirement.
Just my opinion

Remember friends that the text Travis quoted was *_added_* in the 2010
edition of -13. Dewayne's inquiry began with a note that his project
was governed by the 2007. Still, the value for dry system water
delivery time of 15 seconds for residential occupancies was the first
item in Table 7.2.3.6.1.

It can be R or I occupancy. It doesn't matter. It is the fact
you are protecting a dwelling unit with a dry pipe system.
7.2.3.6.3 For dry pipe systems protecting dwelling unit portions
of any occupancy, the sprinklers in the dwelling unit shall have a
maximum water delivery time of 15 seconds to the
single most remote sprinkler.
It seems like you have 15 seconds regardless. Now, if you have a
dry pipe valve on the first floor and I believe you said these
were on the 5th floor, it seems quite unlikely you will get 15
seconds. My suggestion is to find a way to supply these
sprinklers in the dwelling units from a wet pipe system.

That was one of my concerns also. R-2 floor occupancy,
calculating it per light hazard but using residential heads.
If the R-2 occupancy is what would dictate the 15sec delivery
time then it wouldn’t matter what type of heads I used in the
residential areas.

Double check delivery times. I think you need a 15 second
delivery time in residential areas.

The dry portion below the attic was laid out at max 15x15
spacing with the
lines at 15ft above the floor. The way the rooms layout
there are long
runs with 8ft ceilings so I was going to drop down once to
feed all these
rooms with one line but I still need to size it. This
reviewer will still
make us calculate the residential build out portion. I can
get by with a
1 1/4" line calculating 4 heads.

If I'm understanding
The roof system is unchanged and your adding a lower
supply to be rooms.
Use standard qr heads and same pipe sizes
The roof is still most demanding

NFPA 13 (07ed)
I have an existing 5th floor shell space that is installed
as a light
hazard dry system that has pipe in the shell space and in
the attic. They
are turning this floor into a dormitory (R-2).
1)Can I use listed residential heads on return bends and
only pick up 4
heads per 11.3.1.1 or will I need to pick up 1950SF? What
if there are
incidental areas such as a laundry room, ect. in the same
areas as the
dorm rooms?
2)What would be the required trip time be per Table
7.2.3.6.1? 15sec for
residential or 60sec for light hazard?
Thanks,
