During fixed fire system inspection, what gauge reading indicates a healthy system?

• A. Green
• B. Red
• C. Yellow
• D. If equipped with a gauge, the needle must be in the green

Answer: (D)

Gauge readings show whether the fixed fire suppression system is within its intended pressure and ready to operate. The healthiest state is when the needle sits in the green area, but only if a gauge is installed. Green indicates normal, in-range pressure; red means a fault or out-of-range pressure; yellow is a warning or approaching limits. Therefore, stating that, if there is a gauge, the needle must be in green best reflects the normal, ready condition while acknowledging that some systems may not have a gauge.
