Water motor gongs and pressure switches shall be inspected at what interval?

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

Answer: (B)

Quarterly inspections are used for water motor gongs and pressure switches because these alarm-related components depend on mechanical movement and electrical contacts that can wear, corrode, or loosen over time. The water motor gong should be tested to confirm it rings properly when water flow occurs, and the pressure switch should be checked to ensure it triggers the alarm correctly as pressure changes. Performing these checks every quarter balances reliability with practicality, catching developing faults without the redundancy of more frequent checks. Weekly checks are typically not necessary for these devices, monthly checks would be more frequent than required, and waiting until annually could miss developing issues. So, the appropriate interval is quarterly.
