Kidde 2-in-1 Combination Smoke and Carbon Monoxide Alarm with Voice Alerts, 120V AC, Model I12010SCOCA



Kidde combination Smoke & Carbon Monoxide alarms offer protection from two deadly threats in one. These combination devices use breakthrough technology to offer a fast response to real fires, including smoldering and fast-flaming, as well as protect you from carbon monoxide and dramatically reduce the chance of nuisance alarms.


  • Combined Smoke & Carbon Monoxide Alarm – A single unit can be installed where previously, two were needed. Reduces installation time and protects against both fire and carbon monoxide dangers
  • Intelligent Sensor Technology – Combines the detection capabilities of an ionization smoke sensor with that of an electrochemical sensor, which is used to detect CO. When either sensor notices a potential hazard, the alarm will adjust its smoke sensitivity to differentiate between a real hazard and a false one
  • Voice Warning – Announces the hazard type detected (in both English and French). Alarm announces “Fire! Fire!” when a smoke or fire hazard is detected and announces “Warning! Carbon Monoxide!” when a CO hazard is detected or “Low Battery!”. 
  • 10-Year Sealed Lithium Battery Backup – Eliminates the need to replace the battery. No battery to replace for the life of the alarm (10 years). Battery backup automatically activates when the alarm is attached to the mounting bracket
  • Multi-function One Button Design includes:

    • Hush Feature – Temporarily silences nuisance alarms.

    • Test Feature – Simultaneously tests the unit’s electronics and verifies alarm operation

  • Tamper Resist Feature – Unit will lock to mounting bracket to deter theft or tampering
