Why Choose First Alert Detectors?
Whole-Home Smoke Detection
Hardwired smoke alarms connect across the home, reduce false cooking alarms, and keep working during power outages.
Gas & Carbon Monoxide Alerts
Plug-in combo alarms detect natural gas, propane, and CO—showing live levels and backup power to protect during outages.
Automatic Water Shutoff
The L2 Wi-Fi water sensor shuts down HVAC equipment during drain overflow and sends phone alerts. No batteries needed.
