Per NFPA 13 (2013 and other editions too) - 8.7.4.1.1.2 sidewalls can be placed up to 18" below noncombustible or limited combustible ceilings when listed for such use.

Does anyone know of a sprinkler that is listed for 18"? I have only ever seen 12". This would be a lifesaver if the elusive 18" listed sidewall exists.
