Which references may I bring to the R-16 exam?
PSI's R-16 reference list includes NFPA 10, 11, 12, 12A, 13 (2016), 14, 17, 17A, 24, 25, 72 (2016), 96 and 2001, plus the 2018 IPC, 2018 IRC and 2015 Uniform Plumbing Code, bound and tabbed with permanent tabs only.
Does R-16 cover fire alarm work?
Partly. Heat and Smoke Detectors is 8 of the 50 items, and the R-16 scope includes low voltage signaling systems; other electrical devices, apparatus and wiring must be subcontracted to a properly licensed contractor.
