Which pairing correctly matches alarm type with its inspection frequency?

• A. Supervised water level alarm — Quarterly
• B. Supervised water level alarm — Daily
• C. Nonsupervised air pressure source — Daily
• D. Nonsupervised air pressure source — Quarterly

Answer: (A)

Supervised alarms are monitored by the system, so they’re checked on a schedule that confirms both the alarm function and that the supervision circuit is healthy. For a water level alarm that is supervised, a quarterly inspection provides a practical, reliable cadence to verify operation, status indication, and that the supervision pathway remains intact without the need for daily checking.

Daily inspection of a supervised water level alarm would be overly burdensome and unnecessary because the system is continuously watching that device. Conversely, the other pairing suggests a daily check for a nonsupervised air pressure source, which isn’t how these unsupervised devices are typically scheduled to be verified, and the quarterly option for a nonsupervised air pressure source doesn’t align with how these items are usually prioritized in standard practice.
