Question: Regarding the wiring between an ancillary relay and the building equipment it controls (e.g., a fan starter), which statement is true regarding standard supervision?

Answer options: ✅ It is usually not supervised for wire faults.

• It must be Class A supervised.
• It must use 24VDC only.
• It must be red-jacketed cable.

Correct answer: It is usually not supervised for wire faults.

Explanation: While the relay itself is part of the FACP circuit, the actual cabling to the motor starter or fan is often not supervised for 'opens' or 'shorts' unless specifically required by the design (e.g., smoke control). S524 distinguishes between the supervised output circuit and the ancillary wiring.
