10-Year Battery Combo Smoke, Fire, and Carbon Monoxide Alarm - USI/SMCO/10YR/V

The Universal Security Instruments 10-Year Battery Smoke, Fire, and Carbon Monoxide Alarm with Voice Alerts delivers complete home hazard protection with zero electrical wiring required. Running on a sealed lithium power cell, this standalone battery operated carbon monoxide alarm monitors your living space continuously, even during power outages. Advanced Sensing Plus Multi-Criteria Detection allows this 10 year combo alarm to rapidly spot fast-flaming fires alongside slow, smoldering fires while actively filtering out false triggers from cooking steam or humidity.

An integrated electrochemical sensor continuously checks for dangerous CO gas, making this an essential battery powered carbon monoxide detector for bedrooms and hallways. Built-in voice notifications announce the precise threat type, helping you distinguish between smoke hazards, carbon monoxide leaks, and maintenance warnings. Choosing a wireless 10 year combo detector simplifies installation on any ceiling or wall while ensuring full safety code compliance and eliminating low-battery chirps for a complete decade.
