Being this is in Mass.

There are no amendments to 527 CMR 12:00 that would require this, I am of the opinion that the State Building Code is silent regarding the source of energy for fire alarm systems (although I do not have one with me).

Multi station smokes are another issue in new construction they would most likely (residntial) require AFCI protection (bedrooms).
