We're currently working on a school project. There's a suspended ceiling throughout much of the school. The project requires "total coverage", but I'm not sure whether this applies above the ceiling, below the ceiling, or both.
We're under NFPA 72, but 72 does not seem to clarify this either way.
Are smoke detectors required above and below ceilings, for "total coverage"?

2016 NFPA 72 188.8.131.52 "...total cover-age of a building or a portion thereof, shall include all rooms, halls, storage areas, basements, attics, lofts, spaces above suspended ceilings, and other subdivisions and accessible spaces." sections 184.108.40.206.1-220.127.116.11.5 offer modifications/exceptions, might want to read through those and the annex language.

Is the building sprinklered in accordance with NFPA 13?

It comes down to what items are in the attic:

Jon is correct for the definition of "total coverage." I believe the issue isn't "is smoke detection required in the attic per code?" it is "the project requires total coverage and what does that mean?"

The IBC (or the NFPA 101 Life Safety Code) would be the scoping Code for automatic smoke detection system (ASDS) in Group E Education occupancies per 907.2.3. This section identifies where manual fire alarm systems are required and includes exceptions IF automatic sprinkler systems are installed throughout but does not include a requirement for an ASDS to be installed "throughout."

Ask the AHJ what they are requiring.

NFPA is a standard for installation of fire alarm system is not the code requirement , as Todd mention IBC should be the guideline.
