Is AFCI protection required for an individual branch circuit to a fire alarm system?

AFCI (Arc-Fault Circuit Interrupter) protection is an important safety feature in electrical installations that help prevent electrical fires caused by arc faults. The requirements can be influenced by the National Electrical Code (NEC) as well as local regulations.

Regarding fire alarm systems, AFCI protection is typically required for circuits serving dwelling units, which includes circuits that supply power to fire alarm systems. This is in alignment with the NEC's approach to enhancing safety in residential settings by mitigating risks related to arcing, which could lead to fires.

By ensuring that circuits for fire alarms are protected by AFCIs, it helps to ensure that these critical safety systems remain operational during potential electrical failures, contributing to overall safety for occupants and property. Thus, the answer to whether AFCI protection is required for a branch circuit to a fire alarm system is indeed affirmative, as the intention is to maintain high safety standards in residential electrical systems.
