Where should cable splices in a fire alarm notification circuit be made?

• A. Boxes
• B. Walls
• C. Enclosures
• D. Fire alarm devices

Answer: (A)

Splices in a fire alarm notification circuit must be protected and accessible, so they’re made inside an approved electrical box with a cover. The box provides mechanical protection for the conductors and a listed method for making the splice, which keeps the circuit reliable and serviceable. Splicing in walls without a proper box isn’t allowed because the splice would be unprotected and not readily accessible for testing or replacement. Splices should not be inside a fire alarm device; devices contain their own wiring and aren’t intended as splice points. Using a box—an enclosure specifically designed for splices—meets the requirement for a safe, accessible splice point.
