(B) A separate fire alarm system is not required in buildings that are equipped throughout with an approved supervised automatic sprinkler system installed in accordance with Section 903.3.1.1 or 903.3.1.2 and having a local alarm to notify all occupants.

The section number 1104.25 itself, will stay as part of this code for numbering alignment but will not have any requirements attached to it.
