EC's = 5 heads minimum and can't lower the density.

This sounds like maybe an older spec that was update with a new head but the density did not get updated? Is the specifying engineer very familiar with fire sprinklers?

I'm working on a retail store and the engineer has called for Tyco EC-11 heads with a .18/2500 density. I realize the .18/2500 falls on the OH-2 curve but the cut sheet for the head is rated at .20/1500 for OH-2. How would you go about designing to these specs?
