FAQ
FAQ
How do I know when to replace the battery?
The smoke detector will usually emit a chirping sound when the battery is low, indicating it's time to replace it. It is recommended to test your smoke detector monthly and replace the battery at least once a year if it uses standard batteries.
How do I test my battery-operated smoke detector?
Press and hold the test button on the smoke detector until you hear a loud siren. This ensures that the battery and alarm are working properly. If the sound is weak or nonexistent, replace the battery immediately.
How do I maintain my battery-operated smoke detector?
Regular maintenance includes:
1. Testing the alarm monthly.
2. Replacing the battery at least once a year (or according to the manufacturer’s recommendations). 3. Cleaning the unit with a vacuum cleaner or a soft brush attachment to remove dust and debris.
4. Replacing the entire smoke detector every 10 years, as sensors can degrade over time.
