First Alert 10-Year Battery Smoke Alarm with Precision Detection — Sealed Long-Life Power & Nuisance Resistance

The First Alert 10-Year Battery Smoke Alarm is a sealed-battery smoke detector with Precision Detection technology that provides a decade of maintenance-free fire warning.

This compact, hardwired-alternative alarm is designed to simplify home safety by combining long-life power with improved sensing to cut down on cooking-related false alerts. The sealed 10-year battery is permanently installed, so you avoid periodic battery swaps and the nuisance chirps that come with low power. Built-in features include a test/silence button and an end-of-life indicator that signals when the unit should be replaced, making it a straightforward option for bedrooms, hallways, and common areas.

How does the alarm reduce false alerts from cooking?

Precision Detection sensing balances sensitivity and nuisance resistance so the alarm is less likely to trigger from routine kitchen activity while still responding to real smoke patterns. It analyzes the particle signatures common to slow-smoldering and fast-flaming fires to reduce unnecessary disruptions.

• Advanced sensing algorithm minimizes triggers from light smoke and steam
• Designed to meet updated industry standards for nuisance resistance
• Suitable placement advice: outside sleeping areas, not directly over stoves

What does the sealed 10-year battery mean for maintenance?

The alarm arrives with a permanently installed battery rated to power the unit for up to ten years, removing the need to change batteries annually. When the battery reaches its designed end of life, the alarm will provide a clear end-of-life warning so you know when replacement is necessary.

• No annual battery removal or replacement required
• Eliminates low-battery chirps that interrupt sleep
• End-of-life alert indicates when to replace the entire alarm after its service life

How simple is installation and everyday use?

Installation is fast and tool-friendly; the unit mounts to the ceiling or wall and snaps into its bracket for secure placement. Everyday checks are easy via the test/silence button, which lets you verify the alarm is operational or temporarily mute nuisance alarms without disabling protection.

• Quick-mount bracket for ceiling or wall installation
• Test/silence button for routine checks and temporary silencing
• Lightweight design makes placement and handling straightforward

What safety indicators and lifecycle notices are included?

The alarm contains audible alerts and a clear end-of-life signal so you’ll know when the device should be replaced. Built-in cues help ensure the alarm remains an effective part of your home safety plan throughout its lifespan.

• Loud alarm for prompt warning during smoke events
• End-of-life notification to prompt timely replacement
• Visual and audible signals for testing and status checks

Who this product is for: Homeowners, renters, and property managers who want a low-maintenance smoke alarm that meets current nuisance-reduction standards. It’s a solid choice for bedrooms, hallways, and general living spaces where a reliable, long-lasting detector is preferred over alarms that require frequent battery changes or complicated wiring.
