This edition now adds 2-level car stackers to Extra Hazard Group 2.  Is it the intent to provide EH2 at the ceiling level above the 2-level car stacker and no other sprinkler protection is required, i.e. intermediate level sprinklers?

In a 16 bed facility where the occupants are not capable of self preservation, where they will be required to relocate patients from one side of a fire wall to another; the sprinkler system is zoned to correspond with each fire area in the building. Our question is - whether or not the dry system in the attic needs to be split into zones as well?
