TL;DR
A notification appliance is any device a fire alarm system uses to alert occupants — horns, strobes, speakers, chimes, and combination units — wired on supervised circuits from the alarm panel. NFPA 72 sets their performance: audible coverage loud enough above ambient sound, synchronized strobe flashes, and ADA-driven placement of visual units in public and hearing-accessible spaces.
