How often should I replace my smoke alarm?

First Alert recommends replacing smoke alarms every ten years. This timeframe is based on the lifespan of the smoke detector’s internal components, which can deteriorate over time and may not function properly after this period. It is crucial to ensure that smoke alarms continue to provide reliable protection for your home and family. In addition, it is a good practice to test your smoke alarms monthly to ensure they are functioning correctly. If you are using battery-operated smoke alarms, be sure to change the batteries at least once a year to maintain optimal performance. Some smoke alarms come with a sealed battery that lasts for the life of the alarm, which is typically ten years, but it is still important to replace the entire unit when the time comes. For more specific guidance and information, checking the manufacturer's recommendations on the current First Alert website may be helpful.
