Bought these then decided to get some hardwired ones. Will sell for $15 each or $75 for all 6 of them. Does not include the 9V batteries.
Here are some key features:
- Precision Detection technology helps reduce cooking nuisance alarms and provides early warning.
- Provides reliable 2-in-1 protection against both smoke and carbon monoxide
- End-of-life warning lets you know when it’s time to replace the alarm
- Battery-operated alarm allows for easy installation and maintenance
- Test/silence button for efficient testing to ensure alarm is working properly
