NEMA ABP 11-2016 explains that arc-fault circuit interrupters (AFCI) provide increased fire protection for the electrical installation. There is no evidence that the circuit supplying smoke alarms should be exempt from these increased protection requirements. Power supply reliability for smoke alarms is not impacted by the installation of an AFCI.
