The main line pressure, operation of the source of supply, and the reserve source are monitored at which alarm?

• A. All of the above
• B. Area
• C. Master
• D. Local

Answer: (C)

Central monitoring of the medical gas system is handled by the master alarm. It tracks the main line pressure, whether the primary source of supply is operating, and the status of the reserve (backup) source. Because this alarm provides a system-wide view, any drop in pressure or failure in either the main or backup supply will trigger it, signaling staff to act to maintain uninterrupted patient gas service. Area alarms pertain to a specific zone, and local alarms alert a single outlet, so they don’t reflect the overall status of the entire gas system.
