Kidde Combination Smoke and CO Alarm

Ideal for all Living Spaces


Kidde's combination alarms quickly alert to both the presence of smoke hazards and dangerous levels of carbon monoxide (CO), a poisonous gas found in many homes. CO is generated by heating and fuel-burning appliances, including fireplaces, water heaters, gas ovens, and generators, and a CO alarm should be installed on every level of a home. A combination smoke and CO detector can alert to both dangers, in one discrete, space-saving alarm.


Features & Benefits
  • Double the Detection - Alerts to both smoke & carbon monoxide (CO) using a single, cost-effective device.

  • Worry-Free 10-Year Backup Battery - No battery changes for 10 years. Avoids inconvenient battery replacements and saves up to $40 over the life of the device.

  • Voice Alerts - Crystal-clear voice alerts tell exactly why the alarm is sounding so reaction time is quicker.

  • Interconnected Alarms - When one alarm sounds, they all sound, so an emergency is never missed.

  • Self-testing Alarms - For added assurance, internal components ensure alarm is always operating as expected.

  • Simple Installation - Easy to install with included twist-and-click mounting bracket.

  • End-of-life Notifications - No low battery chirps! The alarm beeps to remind you it's time to replace it 10 years after it is powered.


Alarm Warnings - featuring multi-color LEDs

Fire: The red LED will flash in sync with the alarm pattern (3 long beeps). The alarm will repeat this pattern until the unit is reset or smoke is eliminated.
