Question: 1 / 555

When is it necessary to replace a lithium smoke alarm?

Every 5 years

Every 7 years

Every 10 years

Replacing a lithium smoke alarm every 10 years is necessary because, over time, the sensor components can degrade, and the battery may lose its effectiveness, even if it's designed to last for a long duration. Smoke alarms are critical for detecting smoke and ensuring safety, and their reliability can diminish after a decade. This timeframe aligns with national fire safety guidelines that recommend the replacement of smoke alarms to maintain optimal functionality and to ensure that they will respond adequately in an emergency. Regular checks and maintenance are important, but replacing the alarm at this interval is crucial to ensure that you have a dependable line of defense against fire hazards.
