In general, how often shall all smoke detectors be tested?

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

Answer: (B)

Testing all smoke detectors on a regular, comprehensive basis is about ensuring the entire fire alarm system works as a coordinated unit, not just individual units. A yearly test is the standard maintenance interval because it allows a full check of every detector, the interconnections, power supply, and the control panel, ensuring everything signals correctly together. Monthly checks are useful for quick functional confirmation of individual units, but they don’t substitute for a complete system verification. Weekly or biweekly testing is excessive for routine maintenance and isn’t needed to maintain reliability. Therefore, the general practice is to schedule a full system test annually.
