Review Summary

This is the summary of consumer reviews for Kidde KN-COSM-IB Hardwire CO and Smoke Alarm with Battery Backup and Voice Warning, Interconnectable. The BoolPool rating for this product is Very Good, with 4.10 stars, and the price range is $30.00-$62.00.

The Kidde KN-COSM-IB combines carbon monoxide and ionization smoke alarm, providing two important safety devices in a single unit. It requires hard wire installation powered by home’s electricity in order to provide continuous protection. It easily mounts on the ceiling or wall and comes with a front loading battery installation. This speeds up replacement process by eliminating the need to remove the unit completely and re-installing. The alarm includes a voice warning system that helps eliminate confusion, as it tells you if its detected fire or carbon monoxide, if it needs a new battery or end of life alarm. The alarm also allows you to easily silence nuisance alarms using its convenient Smart Hush feature.

This alarm has 9 volt battery backup, which protects you and your family even during a power outage. This talking combo alarm is powered by your home’s electricity and can interconnect with other smoke alarms in your home. Experts recommend interconnected alarms, because when one sounds, they all sound, providing an early warning against fire by dramatically increasing your ability to hear an alarm anywhere in your home, regardless of where the danger starts. The device is provided with two LEDs - flashing green for normal operation and flashing red for alarm conditions.

However the only concern with the unit is sometimes it chirps non-emergency alarm even 30 seconds even after installing new batteries.

Overall, the Kidde KN-COSM-IB combined with safety and a temper resistant feature is perfect dual detector alarm at a reasonable price.
