The Kidde P3010 Series Carbon Monoxide (CO) Alarms are sealed-in lithium battery devices that use electrochemical sensing technology to monitor CO levels. Each alarm automatically activates when it is attached to the mounting bracket, eliminating the need for pull tags or switches to activate the alarm. At the end of alarm life, the unit will chirp, indicating the alarm is in need of replacement. The Kidde KN-COB Series Carbon Monoxide Alarms are available as battery operated devices or AC powered plug-in units with battery back-up. These alarms are suitable for all living areas. In addition, they offer worry-free features to make installation easy, and to help users be aware of replacement requirements.
