There is no prohibition to having a pre-action system adjacent to a wet sprinkler system. There might be storage configurations or processes where you want the additional protection of a double interlocked pre-action system, but there is no need for that level through the remaining spaces. The detection would only be required over the area protected by the pre action system.

There is no separation between the two system types.
