First Alert SM310 10-Year Sealed Battery Dual Sensor Smoke Alarm | Test & Silence

The SM310 from First Alert delivers reliable protection for modern homes with advanced sensing technology and two sensors that monitor for both fast flaming and slow smoldering fires. Built to work with the realities of daily life, it aims to reduce false alarms while staying ready to alert you when danger arises.

Why it stands out

• Precision Detection technology aligns with current industry standards to minimize cooking nuisance alarms while providing early warning in a home fire emergency.
• A 10-year sealed battery eliminates the need for regular battery replacements and prevents low battery chirps for the life of the alarm.
• Dual sensors offer broader coverage by responding to both fast burning flames and slower, smoldering fires.
• The built-in test and silence button makes it easy to verify operation and temporarily silence nuisance alarms without compromising safety.
• An end-of-life warning helps you plan replacement before performance declines.

In everyday use, you will appreciate the low maintenance design: no battery swaps to worry about, and simple testing to confirm the unit is functioning. The compact form fits common hallways or living spaces, keeping protection close at hand where it matters most.

Practical scenarios

• Cooking spillovers in the kitchen can trigger alarms; precision sensing aims to distinguish these events from real fire threats.
• Living room and bedrooms receive early alerts in the rare case of smoldering fires that start slowly over time.

Note that this device meets current safety standards and is designed to provide timely alerts without guaranteeing results. For comprehensive protection, pair it with additional detectors as needed for your home.
