Which wire specification is indicated for grounding a fire alarm, according to the source material?

• A. 12/1
• B. 18/1
• C. 22/2
• D. 14/1

Answer: (C)

Grounding a fire alarm uses a small, two-conductor cable so the grounding path can be run easily alongside the other alarm conductors while still providing a reliable reference for the low-voltage circuit. The material specifies 22/2, meaning two insulated conductors at 22 AWG, which is appropriate for the low-current grounding needs of these systems and keeps installation flexible and cost-effective. Larger gauges or single-conductor options would be unnecessary for this purpose and are not what the material describes for this grounding task.
