Bullseye. 13 says Hydraulic Design Sign and 25 asks about the
Hydraulic Nameplate. Nothing says hang a sign to say Pipe Schedule so
you know it isn't a hydraulic system.
Another related signage issue. 13 (07 ed) requires a new General
Information sign with up to 15 items (including things like location
of all auxiliary drains). NFPA 25 (08 ed) also has a new requirement
to check for the presence of a General sign identifying just a couple
of these items. It does make it a little more difficult when
'splaining the system was installed prior to the requirement when
there are no required records available.
Question to the AHJ's: Since the IFC (I believe) and certainly NFPA
25 require records of the shop drawings, etc to be maintained, what do
you do when the owner does not have them?

When
did code require systems to be hydraulically designed? I believe
sometime or
another it was only required when a system was gridded.

By 1974 it was in 7-1.2, so I think that if your jurisdiction had
adopted a
NFPA 13 1974 or newer it would have been required. Many
jurisdictions never
had a formal adoption of 13, they just "Allowed" it to be used when
they had
a sprinkler installation, which often allowed it to be used piece
meal.

The requirement is in the 1983 edition, so the requirement was there
in
1985.
It's not in my 1961 edition. So it was added sometime between 1961
and 1983.

It seems that the data plates are often left to the end of the job and
forgotten. I had one job where the same thing occurred, insurance
inspection and the owner was written up for no plates among other
things.
While we were fixing the other deficiencies the owner asked about the
plates, I explained what we would need to do to verify the system
data,
which he realized wasn't going to be cheap, and then he asked if we
could
just fill something in because the inspector wouldn't know the
difference
anyway. It goes without saying that we did not oblige him in that
matter.
We finished the other work and that's the last we heard of the
situation. He
probably found some jack-leg that filled out the plates for a couple
of
bucks.
I've got a 1989 NFPA 13 and it's in there, 7-1.2

Subject: Hydraulic Data Plate
Hello sprinklerforum,
When did it the requirement for a hydraulic data plate to be posted
become a part of NFPA 13?
I have a customer that just went through an insurance inspection...
They
wrote them up for not having the data plates posted. This is a 10
story
building and the floors are fed from the standpipe on each floor. The
company that installed the system back in 85 is not to be found
anymore.
The HOA does not want to tear up the units so we can trace the pipe
to
reproduce the calcs (or pay what I would charge for that). I'm open
to
suggestions. I do have a call in to the AHJ about plans but he does
not
think they exist any more.
