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.
When the building occupancy does not require occupant notification via a fire alarm system, occupant notification for sprinkler flow is unnecessary per the occupancy codes.
Stick to the book so that personal opinions cannot enter into the process. Strive to make your plans as objective as possible. If things become subjective, personal or confrontational, it may cause the AHJ to exceed his or her authority. This is not a good thing to have happen, as it may not be correctable.
Know and understand the rules and codes adopted by the jurisdiction. Own a copy of the local building codes and understand both the administrative and technical portions. Knowledge is power. Know your responsibilities and the limited powers of the AHJ. Know who the AHJ is. Code knowledge will ensure successful project design and construction progress and protect your design and your client from unnecessary requirements
But the law complicates things—and with good reason, of course. We apply for construction permits, inspections and certificates of occupancy for new construction and alterations. And our work requires review, during the design and construction, by an “authority having jurisdiction” (AHJ).
