Pros & Cons
The Kidde KN-COSM-B carbon monoxide and smoke alarm combines two important safety devices in a single unit. It can easily be mounted on the ceiling or on the walls thus reducing the installation time and helps to keep home décor attractive. The alarm includes a loud and clear voice warning system that announces “Fire, Carbon Monoxide, Low Battery” and “Smart Hush Activation”. The voice alarm eliminates confusion and clearly warns you and your family of a smoke or carbon monoxide danger, or if your battery or device is in need of replacement. This technically advanced combination alarm is battery operated, protecting you and your family even during power outage.
This device is suitable for all living areas and has a 7-year shelf life and a 5-year limited warranty. This smoke alarm uses ionization sensing technology. Ionization sensing alarms may detect invisible fire particles (associated with flaming fires) sooner than photoelectric alarms. The device is provided with two LEDs - flashing green for normal operation and flashing red for alarm conditions. This device ensures that the unit cannot be accidentally mounted without batteries being installed.
The sensor is very sensitive and detects even the hint of smoke from cooking pans thus requiring frequent attention to push the hush button to silence non-emergency alarms. It is a high battery consumption device that needs frequent battery replacements, but is still considered economical by many keeping their family safety in mind. Some reviewers also noticed that the device either stopped working after the first battery change or was chirping continuously every 30 seconds due to malfunction.
Overall, the Kidde KN-COSM-B Combination Carbon Monoxide and Smoke Alarm is a perfect combination of safety and temper-resistant features, beautiful neutral white finish and value for money and thus is a highly recommended smoke alarm unit. This combination smoke/CO alarm is UL listed, so you can be confident of its quality, and it is backed by a five-year limited warranty.
