Smoke & Carbon Monoxide Safety
Smoke and carbon monoxide alarms provide critical early warning when dangerous conditions develop inside your home. From smoke caused by a developing fire to invisible, odorless carbon monoxide, reliable detection can give your household valuable time to respond and get to safety.
Explore essential smoke alarms, carbon monoxide detectors, combination alarms, smart detectors, and portable monitoring solutions designed for different areas of the home. Choosing dependable detectors—and keeping them properly installed, tested, and maintained—is a fundamental part of a well-prepared household.
First Alert Hardwired Smoke Alarm
The First Alert 9120BA Hardwired Smoke Alarm provides continuous household fire monitoring using a 120V hardwired power connection backed by a replaceable 9V battery. Its ionization sensor is designed to respond effectively to fast-flaming fires, while the loud 85 dB alarm, test/silence control and status indicators make it a practical choice for everyday home fire protection.
One of its biggest advantages is hardwired interconnectivity. Multiple compatible First Alert or BRK alarms can be connected so that when one detects smoke, the interconnected alarms sound throughout the home—particularly valuable in larger or multi-level houses. Combined with battery backup during outages and a 10-year limited warranty, the 9120BA provides a dependable foundation for a comprehensive home smoke-detection system.


Airthings Corentium Home Radon Detector
The Airthings Corentium Home Radon Detector provides a simple way to continuously monitor one of the most difficult household hazards to detect: radon gas. Its digital display shows short- and long-term radon averages directly on the device, with initial readings available within about 24 hours. Because it operates on three AAA batteries for approximately two years, it can be positioned around the home without outlets, cables, subscriptions or laboratory testing.
Continuous monitoring also allows homeowners to observe how levels change over time and verify whether mitigation measures are working. For your website, however, I would classify this under Home Air Quality & Radon Safety, rather than Smoke & Carbon Monoxide Safety, because it does not detect either smoke or CO.


Kidde Smoke & Carbon Monoxide Alarm
The Kidde Combination Smoke & Carbon Monoxide Alarm provides two essential layers of home protection in one compact device, continuously monitoring for both smoke and dangerous carbon monoxide. Its battery-powered design keeps the alarm operating even when household electricity is unavailable, while Kidde's newer sensing technology is designed to deliver fast warnings while reducing nuisance alarms associated with everyday cooking.
Simple installation, self-testing components and an accessible Test/Hush function make it a practical choice for strengthening everyday home safety. For emergency preparedness in particular, combining smoke and CO detection in a single battery-powered unit provides valuable protection during fires, power outages and heating emergencies when early warning can make a critical difference.
