How often shall waterflow alarm and supervisory alarm devices be inspected?

• A. Monthly
• B. Quarterly
• C. Annually
• D. Bi-annually

Answer: (B)

Understanding how often waterflow alarm and supervisory alarm devices are inspected comes down to balancing reliable signaling with practical maintenance. These alarms must be checked regularly to confirm they respond correctly when water flows or when a supervisory condition (like a valve position or detector) is present. The standard interval of a quarterly inspection keeps this balance: it’s frequent enough to catch developing faults in sensors, wiring, or valve positions, yet not so frequent that routine maintenance becomes overly burdensome. Monthly checks would be more than needed for these components, while waiting a year or six months could leave faults hidden for too long. During the quarterly inspection, verify that the waterflow alarm triggers properly on test, that the supervisory alarm signals are received and interpreted correctly, and that related wiring, tamper switches, and indicators are functioning, then document the results.
