8. Maintenance
Regular Cleaning:
Clean your smoke detector at least once a month to prevent dust and debris buildup, which can affect performance.
- Gently vacuum the ventilation slots using a soft brush attachment.
- Wipe the exterior with a clean, damp cloth. Do not use cleaning solvents or sprays.
Battery:
The detector is equipped with a sealed 10-year battery. It is not user-replaceable. When the battery is low, the detector will emit a low battery warning (a chirp and/or app notification). Replace the entire unit when the low battery warning persists or after 10 years of operation.
9. Troubleshooting
- Alarm sounds intermittently or chirps: This usually indicates a low battery. Since the battery is sealed, the unit needs to be replaced.
- False alarms:
- Check for sources of smoke or steam (e.g., cooking, hot showers, fireplaces).
- Clean the detector to remove dust or insects.
- Relocate the detector if it is too close to kitchens or bathrooms.
- Detector does not connect to Wi-Fi:
- Ensure your Wi-Fi network is 2.4GHz. The detector does not support 5GHz Wi-Fi.
- Check your Wi-Fi password for accuracy.
- Move the detector closer to your Wi-Fi router.
- Restart your router and try pairing again.
- Ensure the detector is in pairing mode (rapidly blinking LED).
- No app notifications:
- Ensure your phone has a stable internet connection (cellular or Wi-Fi).
- Check app notification settings on your phone and within the Tuya/Smart Life app.
- Verify that the detector is still connected to Wi-Fi (check its status in the app).
- Test button does not work: Ensure the detector is properly activated and the battery is not depleted. If issues persist, the unit may be faulty and require replacement.
