Well, that's pretty much the final nail in that box lid. Thank you Larry and everyone else for your input.

RECOMMENDATION: Add a new section to read: 5-5.6 Small loading docks, covered platforms, ducts or similar small unheated areas may be protected by dry pendent sprinklers extending through the wall from wet sprinkler piping in an adjacent heated area, as shown in Figure 5-5.6. Where possible, the dry pendent sprinkler shall extend down at a 45° angle. The width of the area to be protected shall not Exceed 7 1/2 ft (2.3 m). Sprinklers shall be spaced not over 12 ft (3.7 m) apart. Add a new Figure 5-5.6 ... SUBSTANTIATION: The above proposed alternative provides a workable solution where antifreeze systems are prohibited. Other than later being moved to the Appendix (Annex), it has remained virtually unchanged since that time. As I remember it, horizontal sidewall sprinklers had only been on the market for a few years prior to this and dry horizontal sprinklers did not become available until many years afterwards.
