USI Sensing Plus Kitchen Smoke & Fire Alarm AMIK3051SC – 10-Year Sealed Battery

Overview

The USI Sensing Plus AMIK3051SC is a 2-in-1 kitchen smoke and fire alarm designed for modern homes. It blends fast flaming and slow smoldering fire detection with a smart, multi-criteria sensor to differentiate smoke profiles and reduce nuisance alerts, all in a single, compact unit.

Powered by a 10-year sealed battery, this alarm delivers maintenance-free protection through a decade of power, including during power outages. A built-in microprocessor helps minimize false alarms, while a loud 85 dB siren and intuitive test/silence controls make it practical for busy households. The tamper-resistant housing adds an extra layer of security, and a 10-year warranty covers both the battery and the alarm.

Smart sensing and reliability

The Sensing Plus technology uses multiple inputs to classify smoke and fire indicators, offering the benefits of both photoelectric and ionization approaches in one device. It’s designed to resist cooking-related false alarms and to withstand high-voltage surges, making it suitable for real-world kitchens and living spaces.

• Multi-criteria detection combines fast flame and slow smoldering fire detection for broader protection.
• AI-inspired processing differentiates smoke types to reduce nuisance alarms.
• Integrated microprocessor improves decision accuracy and minimizes false alerts.

Power, maintenance, and installation

Enjoy 10-year permanent power from a sealed battery included with the alarm, eliminating routine swaps and annoying chirps. A large mounting base helps cover drywall imperfections during retrofits, while a quick activation pull tab speeds up installation.
