How often must alarm monitors take a no-notice test?

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

Answer: (C)

No-notice testing is meant to verify that alarm monitors actually perform when an unexpected event occurs, not just when someone knows a test is coming. The right cadence is quarterly because it checks performance across different times, shifts, and conditions without overburdening daily operations. It helps catch drifting accuracy, equipment faults, or tampering early while keeping the tests frequent enough to maintain real-world readiness. Doing it monthly would be unnecessarily heavy and could dull focus from routine duties, while waiting annually or biannually allows issues to go undetected too long and can leave the system vulnerable. Quarterly strikes the balance, ensuring reliability and timely detection of problems.
