Per 2014 NEC, It is my understanding that AFCI shall not be used for:
fire/smoke detection, burglar alarms that have a central control station.
power for a fire alarm (if its power supply is in metal conduit)
snow and ice melting equipment.
Also, I think AFCI protection is optional for the following:
Any outlet that is GFCI protected.
An outlet in kitchen, laundry room, bathroom, garage, that is not GFCI protected. Such as lighting, vent fans, garbage disposal, gas range, DW, trash compactor, instant hot water.
unfinished rooms , such as attic or basement,
fau circuit
Is this accurate?
