Multiple Choice

Class A, Class N, and Class X circuits should be separated by a distance of not less than ? when run vertically.

Explanation:
In a vertical run, different fire alarm circuit classes need physical separation to prevent heat, electrical interference, or fault effects from one circuit affecting another. The minimum distance required is three feet. This spacing helps keep circuits isolated in a shared shaft, reducing the chance that a fault or heat in one circuit impacts the others. A smaller gap, like one foot, isn’t enough isolation, while much larger gaps aren’t typically required unless space or additional barriers dictate it. If space is limited, you can use barriers or separate compartments to maintain the needed separation.
