Does the 'small room rule' apply to NFPA 13D sprinkler systems?
I could not find any mention of it in 13D. If 13D does not allow it, why not? Submitted anonymously and posted for discussion. Discuss This | Submit Your Question | Subscribe

Small room rule does not apply to NFPA 13D. NFPA 13D, NFPA 13R and NFPA 13 are completely different standards even though they all are installation standards for sprinkler systems.

Also Small Room is defined as a light hazard area. 13D would be considered a residential area. Another interesting thought is this should only apply to standard spray sprinklers as a residential sprinkler operates more like an extended coverage sprinkler and are listed to only operate at a listed coverage at a given pressure. Standard spray sprinklers are listed to be spaced per NFPA 13.

To add to Jeremiah's thought, the residential sprinkler heads act a lot more like extended coverage heads compared to standard spray in regards to obstructions as well, so that is also something to keep in mind when designing their coverage.

No it can't, but there's not much of a need for it. Most listed residential sprinklers allow for greater spacing than standard coverage sprinklers used in full 13 applications. with 20x20 spacing you can be 10-ft off of every wall which is greater than the small room rule of 9-ft from a single wall.
