Why does my First Alert Onelink Safe & Sound smoke alarm sound when no smoke is visible?
- CChristina OdomAug 13, 2025
The unwanted alarm from your First Alert Security System may be triggered by a non-emergency source, such as cooking smoke. You can silence the alarm via the app or the unit button. Additionally, clean the alarm's cover with a soft, clean cloth. If these unwanted alarms persist, consider relocating the alarm, as it might be too close to the kitchen, a cooking appliance, or a steamy bathroom.
