How often should smoke alarms be tested by pressing the test button?

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

Answer: (D)

Testing with the test button confirms that the alarm’s electrical system and audible alert are functioning, so you’ll be warned if a real fire occurs. The best practice is to perform this test monthly. Monthly testing catches problems like a dying battery, loose wiring, or a faulty horn long before they matter, ensuring the device will actually alert occupants when needed. Testing more often isn’t necessary for safety, and testing less often could leave you unaware of a malfunction for extended periods. Some units have sealed batteries or longer lifespans, but monthly tests remain the recommended routine to verify operation.
