Using ICC 2012 and NFPA 72 2010 edition,
Given an occupancy that is not required to have a fire alarm by 907.2.4 and is sprinklered per 903.2.4 thus contains a dedicated function fire alarm unit for water flow monitoring. Does a dedicated function fire alarm control unit require occupant notification beyond the exterior device per 903.4.2?
Common sense would be if the sprinkler activates, occupant notification would be wanted to notify the occupants for evacuation. Without notification, the dedicated function fire alarm control unit would notify the FD but not the occupants of the building.
