Which code corresponds to Fire Alarm - Dwelling?

• A. 3A
• B. 1A
• C. 3DC
• D. 3D

Answer: (D)

Codes combine a general category with a location/subtype indicator. For a fire alarm inside a dwelling, the system uses the fire-alarm category paired with the dwelling indicator, so the exact code that represents a dwelling fire alarm is the one that matches that pairing. The other forms would point to different subtypes or locations (such as non-dwelling settings or other fire-alarm variants), and therefore do not represent a dwelling fire alarm. This is why the code for Fire Alarm - Dwelling is the correct choice.
