Probably because sprinkler water would reach temperatures in excess of 120* (7.7.1.3.1.1) That pertains to combination systems, but I think there's a similar requirement for standard wet systems.

The piping is on the exterior and a drop sprinkler into the oven. An FM plan reviewer stated that FM suggests using a dry system when temps run this high.
