Yeah but … that’s a red herring regarding the question on the table. The spray pattern and droplet size are different from a conventional sprinkler. These are designed to cool the compartments more than wet burning fuel, so applying an attic sprinkler to any space with people or stuff in it is outside of its listing. An attic is an attic and as Travis noted, the standard says that UNUSED attics are light hazard. If there’s any doubt about what a word means in the standard that isn’t fully defined, we go to Merriam Webster’s Collegiate Dictionary, 11th edition which states, “ a room or a space immediately below the roof of a building.” So that’s not a space between floors, only the one below the roof (which has pitches and creases and so forth, hence the unique design and discharge patterns of attic sprinklers) but it has to be unused, otherwise it’s an occupied compartment.

Annex says unused attics are light hazard. So, an attic used for storage would not be unused, nor light hazard. Page 6 of 28 of the tyco data sheet says light hazard. Seems like the AHJ missed the target on this one.
