What do you enter for the "Location" on a standard hydraulic calculation placard?

What do you enter for the "Location" on a standard hydraulic calculation placard?

What do you enter for the "Location" on a standard hydraulic calculation placard?

(OP)


I've always used it to identify the hydraulically most remote area such as "Northeast Corner of Building" or "Plastics Storage Room" etc because often the hydraulically most demanding area is not the area farthest away from the riser.

I do not think this is for the building address.

Sorry for the silly questions lately but there's no such thing as a silly question. This is what happens when you hire a new layout technician trainee who asks questions you may not have thought about in decades. :)

RE: What do you enter for the "Location" on a standard hydraulic calculation placard?

In my sleepy little hollow we indicate the area of the building where the design area is located. I have seen the building address on some risers and I've seen it blank.

RE: What do you enter for the "Location" on a standard hydraulic calculation placard?

I always indicate area of design, as you described...NE corner, etc...

When Sprinkcad automatically populates the calc placard information after calc'ing a drawing, it puts the building address in that space. Like you, I had always assumed it was to correspond with the name of the calc i.e "Attic"

I figure I'm not the one to be second guessing Tyco, so all of our calc placards now show the building address in that space.

RE: What do you enter for the "Location" on a standard hydraulic calculation placard?

Maybe I should start reading the book:

NFPA 13-2010 24.5.2 The sign shall include the following information:

(1) Location of the design area or areas

Which appears to be separate from 24.6's "general information sign"

(1) Name and location of facility protected

RE: What do you enter for the "Location" on a standard hydraulic calculation placard?

I put the room # of the building where the remote area is on that line.

RE: What do you enter for the "Location" on a standard hydraulic calculation placard?

I would say, about 50% of the systems in AZ, that have Hyd. calc. placards, have the address of the building, and the total no. of sprinklers, in the building, written in on the No. of sprinklers area. LOL! Good question. Silly questions are always the best ones!

RE: What do you enter for the "Location" on a standard hydraulic calculation placard?

Figure A.22.3.2(a) has the building address at the top. Unclear to the intent of the placard at this point.

RE: What do you enter for the "Location" on a standard hydraulic calculation placard?

The same figure above has the number of fire sprinklers in the remote area. I've seen both, total sprinklers on a riser and number of sprinklers in the remote area. I use the number of sprinklers in the remote area.

RE: What do you enter for the "Location" on a standard hydraulic calculation placard?

NewtonFP, did you mean A.23.3.2(a) instead of A.22.3.2(a)?
In my NFPA 13 that is the "Summary Sheet" figure, which is a document as opposed to a placard/sign.
Section 25.5 (NFPA 13) addresses the hydraulic signage/placard.
Here is a photo from the NFPA 13 handbook,

It's hard to read, but on that one they put the building floor and hydraulic area number to indicate location of the hydraulic area the placard is talking about, which is what makes intuitive sense to me (which would be helpful if you have multiple hydraulic areas on your plans)

RE: What do you enter for the "Location" on a standard hydraulic calculation placard?

Also from the handbook,
"As-built drawings often become lost or misplaced over time. By keeping a permanent record of the design parameters attached to the system riser, as required by 25.5.1, it is much easier and less costly to perform any future modifications or work on the system. The information contained on such a nameplate is also of vital importance in assessing the ability of the system to
control fires as the building’s occupancy changes or the water supply’s strength deteriorates."

So I take that to confirm the theory that the placard/signs sole purpose is to act as replacement hydraulic data in case the as builts become lost. In that case, the physical building address is doing nothing for the designer who has no as builts, as he can just look outside and find the street sign.. he needs to know which floor and which hydraulic area the placard he is looking at (attached to some valve) is talking about.

RE: What do you enter for the "Location" on a standard hydraulic calculation placard?

Similarly, in response to total sprinklers in building vs. sprinklers in remote area, since the purpose is to replace the hydraulic data lost from having no as builts, the density and other information might not be clear without the knowledge of how many sprinklers were in the design area.. so I would list that, or both the total and the number in the design area
