The Kidde® P3010K-CO is a 10 years, sealed battery, smoke and carbon monoxide alarm that features photoelectric and electrochemical sensing technology with smart hush feature. This combination alarm combines the detection capabilities of a photoelectric sensor with that of an electrochemical sensor, which is used to detect CO. When either sensor notices a potential hazard, it will communicate with the other. Depending on what is detected, the alarm will adjust its smoke sensitivity in order to better discriminate between a real hazard and a false one. This constant communication enhances the alarm's overall performance and significantly reduces the potential for a nuisance alarm.

• Smoke and CO sensing technologies work together to detect real fires faster and reduce cooking-related nuisance alarms
• Sealed-in lithium power supply, no battery replacement required over-the 10 years life of the alarm, eliminates worry about battery removal or unauthorized deactivation of alarm
• Smoke alarm contains advanced photoelectric sensor that may detect visible particles (associated with smouldering fires sooner than ionization alarms
• Alarm automatically activates when attached to the mounting bracket
• Rapidly flashing led alerts user if the alarm has sounded since the last time the test/reset button was used
• Tests alarm circuitry and activates hush features
• Temporarily silences nuisance alarms for approximately 10 min and will not allow hush mode unless the unit is in alarm mode
• Red will blink in conjunction with the alarm sound
• Alarm chirps every 30 sec to indicate the unit is in need of replacement
• End of life indication can be silenced three days at a time up to 30 days to allow for alarm replacement at a more convenient time
