Tanks equipped with supervised water level alarms connected to a constantly attended location shall be inspected how often?

• A. Daily
• B. Weekly
• C. Quarterly
• D. Monthly

Answer: (C)

Tanks with supervised water level alarms that feed a constantly attended location are kept reliable by inspecting them on a quarterly basis. This frequency ensures the supervisory circuit is intact, power and wiring are sound, the water level sensors are functioning correctly, and the alarm signal is reliably received at the attended location. Checking every three months provides a practical balance between keeping the system dependable and avoiding excessive testing, while still catching issues before they can compromise response time.
