Are smoke detectors in residential bedroom areas required to have AFCI protection?

Smoke detectors in residential bedroom areas are indeed required to have AFCI (Arc Fault Circuit Interrupter) protection. This requirement is based on the National Electrical Code (NEC), which emphasizes the importance of providing safe and reliable electrical systems in living spaces. Smoke detectors are critical life safety devices, and AFCI protection helps reduce the risk of electrical fires that can occur due to arcing faults.

By having AFCI protection, these devices can ensure that any potential electrical faults are detectable and that power is interrupted before a hazardous situation develops. This is particularly relevant in areas where people sleep, as a malfunctioning electrical circuit could lead to a fire that may go unnoticed while occupants are asleep.

AFCI protection is applicable not only to general circuits in bedrooms but also extends to the protection of circuits that specifically serve smoke detectors, ensuring comprehensive safety measures in residential environments. This makes the requirement crucial for maintaining a high standard of electrical safety.
