First Alert 10-Year Combination Smoke & Carbon Monoxide Detector

Our review of the First Alert PRC710 PC1210 finds it is a practical, no-fuss safety upgrade for homes and rental properties that need combined smoke and carbon monoxide detection with minimal maintenance. The single biggest reason to buy is the sealed 10-year battery and tamperproof design, which deliver a decade of continuous protection without battery swaps. Installation is straightforward and the photoelectric sensor reduces nuisance trips from cooking or shower steam, making it a sensible choice for kitchens, hallways and bedrooms where false alarms are a common problem.

Key Features

• Combination protection: Integrates a photoelectric smoke sensor and a carbon monoxide alarm in one unit to cover two common household hazards with a single device.
• 10-year sealed battery: Built-in battery is designed to last the life of the alarm so owners do not need to replace batteries during normal use.
• Photoelectric technology: Uses a sensor type that is less likely to trigger false alarms from cooking or shower steam, improving everyday reliability.
• Tamperproof design: The sealed construction meets code for tamperproof alarms and reduces the chance of accidental disconnection or battery removal.
• UL compliance and warranty: Meets UL standards and legislative requirements for 10-year battery alarms and includes a 10-year limited warranty for added peace of mind.

Who It's For

The First Alert PRC710 is aimed at homeowners, landlords and property managers who want low-maintenance, code-compliant detection with a clean installation and a long service life. It is especially useful in locations where nuisance alarms from cooking or steam are a problem, since the photoelectric sensor helps avoid unnecessary disturbances.

Those who need networked or smart-home connected alarms, selectable sensor types beyond photoelectric, or replaceable batteries for easy mid-life service should look elsewhere; this unit emphasizes sealed longevity and simple combination protection rather than advanced connectivity.
