The U.S. Fire Administration recommends testing smoke alarms monthly, changing replaceable batteries as instructed and generally replacing alarms after ten years. These are U.S. recommendations; local rules and the device manual take priority. Treat any possible real fire as an emergency and evacuate immediately.

1. Locate all smoke alarms. USFA recommends coverage on each level and in and outside sleeping areas, but always confirm local installation rules.
2. Read the manufacturing date, model and power type on each alarm. Replaceable-battery, sealed long-life and hardwired alarms require different maintenance.
3. Once a month, use the test button according to the manufacturer's instructions. Do not risk a fall from an unstable ladder to reach a high alarm.
4. Replace removable batteries with the specified type and interval. USFA recommends at least annual replacement for 9-volt battery alarms; never pry open a sealed battery unit.
5. Never paint, cover or disable an alarm. If cooking causes a nuisance alarm, do not remove the battery; consult the model's hush function and ventilation guidance.
6. Record installation or manufacture dates and planned replacements. USFA generally recommends replacing smoke alarms by ten years. If an alarm may indicate a real fire, evacuate at once and call local emergency services.
