Trash Compactor Open Sprinkler?

NFPA 13: states that a sprinkler shall be installed in the trash compactor. For years we have been installing Open sprinklers in the compactor with a solenoid valve, operated by a heat detector or rate of rise detector inside the compactor. There is a trash chute as well, with closed sprinklers on alternating floors.


My question is, "Has the code changed to allow a closed sprinkler in the compactor with out a solenoid valve and heat detector?" 


Please identify where this is in the code.
