3FXB Carbon Monoxide Alarm with Digital Display and Voice Alert: Plug-in type for easy installation
This plug-in carbon monoxide alarm is for homeowners who want reliable protection without complicated installation. It's perfect for placing in your kitchen near gas appliances or in bedrooms where you sleep.
While most CO detectors simply sound an alarm, this model gives you clear information with its digital display. You can see the exact CO level at a glance, not just hear a beep. The voice alert tells you "Warning: carbon monoxide detected" in plain English, so you know immediately what's happening even if you're half-asleep.
The plug-in design means no battery changes, and the two-pack lets you cover multiple rooms. It works silently in the background, but when it detects danger, it responds with unmistakable clarity to keep your family safe.
