It is not mandatory, unless required by the AHJ, to supervise supplementary circuits.

• A. True
• B. False
• C. It Depends
• D. Not Specified

Answer: (A)

Supervision is about ensuring circuit reliability by continuously monitoring for faults. In fire alarm systems, life-safety circuits (like initiating and notification circuits) are normally supervised to guarantee there’s no hidden fault that could stop a detector from signaling or a device from operating. Supplementary circuits are additional circuits that support equipment but aren’t part of the core life-safety signaling path. By code, supervising these circuits is not mandatory by default; it becomes required only if the Authority Having Jurisdiction decides to mandate it for a particular installation. That’s why the statement is true: you don’t have to supervise supplementary circuits unless the AHJ requires it.
