Smart safety you can rely on, now connected

The First Alert SC5 Battery Smart Smoke & CO Alarm combines a trusted 2‑in‑1 detector with modern smart features.

When paired with compatible systems, the SC5 can interconnect with other alarms so a single incident can trigger multiple alerts for faster awareness.

You’ll receive clear voice alerts that name the danger and point to its location in your home, giving you contextual information without ambiguity.

• Interconnect so one alarm sounds across compatible devices
• Notifies via the First Alert app when smoke or CO is detected

In the morning, a low-battery alert saves you from unexpected chirps and last-minute battery changes.
