Which statement correctly matches the inspection frequency to alarm type?

• A. Tanks with supervised water level alarms are inspected weekly
• B. Tanks with supervised water level alarms are inspected quarterly
• C. Tanks with supervised water level alarms are inspected daily
• D. Tanks with supervised water level alarms are inspected annually

Answer: (B)

Supervised alarms are monitored by a central panel or monitoring system, so the test frequency focuses on proving the supervisory circuit and transmission are functioning over time. For water level alarms that are supervised, quarterly inspections provide timely verification of the alarm’s operation and the integrity of the supervisory signal without creating an excessive maintenance burden. During the inspection, you check that the sensor responds to the set water level, the supervisory circuit is being received and acknowledged by the control panel, and that the event is properly logged. You also verify wiring integrity, connections, and any battery backup. Daily checks would be unnecessarily frequent for a supervisory circuit; weekly is also more than typically needed; annual checks risk missing developing faults.
