Working on a project where listed combustible concealed space sprinklers (such as Viking COIN) are required. Data sheets call for a design area of 1,000 sf. However, the combustible concealed spaces on several floors of this motel are compartmented into areas of approx 345 sf via 1-hour rated walls. A 1,000 sf design area would include up to 8 sprinklers, whereas a design area of (1) 1-hour rated compartment would include only 3 sprinklers. I'd love to use the room design method and calc only 3 sprinklers, but since these are specially listed sprinklers and the listing calls for 1,000 sf, I don't believe I'm allowed to do that. Anybody else run into this or have an opinion?
