Q (NFPA 13R, 2007):
As per 6.8.1.5.3.1, closets not larger than 400 CF may be protected by a single sprinkler at the highest ceiling space without regard to obstructions.
If that closet includes space below a combustible stair but the sprinkler at the highest elevation is obstructed from protecting below the stair (but still in compliance with 6.8.1.5.3.1), is an additional sprinkler required to protect under the combustible stair as per NFPA 13 (2007), 8.15.3.1?
Do we apply NFPA 13, 8.15.3.1 in NFPA 13R?
