Travis, I ran into this condition on a project recently and the state required to design per the cut sheet. Our condition was that the Engineer of record (EOR) was responsible and designed the system after the fact to the cut sheet criteria. I had contacted Tyco Tech Services prior to our submittal and they contended that the cut sheet was to be adhered to...suggested for us to calculate to the cut sheet criteria for our files. I would think that would be the thing to do!

The design documents specify to use Tyco EC-11 ex cov sprinklers. The sprinklers are spaced at 16X16 sq ft. Per the data sheet, for OH2 (0.20 density), the sprinkler is req'd to discharge 51 gpm. However, the consultant is saying that because our specified density is 0.19 that we are able to only discharge 48.64 (256*.19)gpm per sprinkler. Has anyone done this before? Is it acceptable? I thought I had to go with the minimum the sprinkler cut sheet shows for OH2 (51 gpm). Any thoughts?
