First Alert SM300-AC Interconnect Hardwire Dual Sensor Smoke Alarm with Battery Backup – 3-Pack

Smart, proactive protection for every room

The First Alert SM300-AC interconnect hardwire smoke alarm delivers thoughtful, practical safety features designed for real homes. It emphasizes accurate detection while reducing false alarms so you’re not interrupted by routine activities, yet remains ready to warn you at the earliest sign of danger.

Two sensor technologies work in tandem to cover different types of fires. The dual sensors provide reliable responses to both slow, smoldering flames and rapid, flaming fires, helping you notice danger sooner while you maintain daily life without constant interruptions.

Interconnected protection for a coordinated alert

With interconnection support for most First Alert and BRK alarms, one alarm sounding can trigger compatible units throughout the home. This creates a synchronized warning that spans multiple rooms, helping you react quickly as a team.

The latching alarm indicator visually identifies the unit that started the alarm or signaled a low battery, making it easier to locate the source when you’re organizing a quick, calm response.

Power you can rely on

Each unit includes a dependable battery backup, ensuring continuous protection even during power outages. This added continuity can be especially valuable in rooms far from the main panel or in areas prone to outages.
