There is a reason, but without details of the conditions (occupancy, building construction, water supply, etc.), it is impossible to pinpoint why FM Global made the recommendation. The installation rules for suppression mode sprinklers are very specific, and apparently something changed since their acceptance by FM Global three years ago or was missed back then that made these sprinklers a bad fit now. You'll need to look at Data Sheets 2-2 and 8-9 to figure it out, or call and ask them.
