By "Rehabilitation Code", what are you referencing?

I was hoping to get some clarification on the need for notification on Group B occupancies. There are few questions built into this.

This scenario is a Group B (not an Ambulatory Care Facility), is 28,000 square feet, has an occupant load of 286 and is fully sprinkled. 2015 code cycle.

 

 - 907.2.2 of the IBC states that a fire alarm system is not required when the total occupancy is less than 500 in a Group B. So in the above scenario there would be no need for activation or notification devices through out the building other than what is needed for the sprinkler system (flow switch, tamper, 1 horn/strobe outside for flow, 1 manual pull station, ect.). Would this be a correct conclusion?

 

Below is where I need a little clarification.

 

 - 904.2 of the Rehabilitation Code, Level III Alteration says to refer to the building code for fire alarm systems. See above.

 - 804.4 of the Rehabilitation Code, Level II Alteration says to refer to THIS CODE and the NFPA 72 for fire alarm systems.

So is THIS CODE referring to the Rehabilitation Code or the Building Code? And if it is referring to the Rehabilitation Code, does this mean that a level II restoration would require full notification based on NFPA 72 in the above scenario, and a Level III would not?

 

Thank you for your time.
