These sprinkler heads have an increased radius of approximately 10 ft and can be spaces about 20 ft apart. But there's more to sprinkler placement than square footage. In section 10.3.4, NFPA 13 clarifies that the maximum distance also varies with the hazards involved: To stop cold soldering, sidewall sprinklers placed on opposing or adjacent walls must not be within the maximum protection area of another sprinkler.

Further, installers may sometimes place specially equipped or specially designed sprinklers close together. More often, sprinkler co verage is found only above such large ducts, with no sprinkler coverage below the ducts. This information may also be publicly available from some municipal water authorities.
