What to do if my FireAngel LSI-601 Smoke Alarm activates when no smoke is visible?

If your FireAngel smoke alarm goes off when there's no visible smoke, first, consider its location. Then, clean the smoke alarm. For the LSI-601 model, wipe the cover with a damp cloth to remove static electricity. Also, check if the battery is correctly fitted and replace it if it's been in use for over 12 months. If the problem persists, contact technical support.
