Kidde Worry-Free Hardwire Smoke and Carbon Monoxide Alarm with 10-year Sealed Battery Backup i12010S-CO-CA

The Kidde i12010SCOCA is a hardwired combination smoke and carbon monoxide alarm that contains a 10-year, sealed battery backup. This alarm uses 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.

The Intelligent sensor technology combines the detection capabilities of an ionization smoke sensor – which is more likely to detect smaller, less visible fire particles, like those produced by flaming fires – with that of an electrochemical sensor, which is used to detect CO.

Since carbon monoxide is present in all fires, having both detection chambers work together in one alarm is a breakthrough in the fire safety industry. 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 in all fires, and significantly reduces the potential for a nuisance alarm.

Leading authorities recommend that both ionization and photoelectric smoke alarms be installed to help insure maximum detection of the various types of fires that can occur within the home. Ionization sensing alarms may detect invisible fire particles (associated with fast flaming fires) sooner than photoelectric alarms.

Photoelectric sensing alarms may detect visible fire particles (associated with slow smoldering fires) sooner than ionization alarms. The i12010SCOCA contains a 10-year tamper proof backup battery that eliminates the need for battery replacement, and ends worry over unauthorized battery removal.

The alarm provides continuous protection from smoke, fire and carbon monoxide, even during power outages. At the end of alarm life, the unit will chirp, indicating the alarm is in need of replacement. The end of life chirp can be temporarily silenced, allowing for replacement at a more convenient time.


  • 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 a 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 sensitiivity 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!”. 
  • 120V Interconnectable – Will interconnect with up to 24 other devices (18 of which can be initiating), including smoke alarms (limit of 12), CO and heat alarms.
  • 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 mounting bracket.
  • Multi-function One Button Design includes:
    • Hush® Feature – Temporarily silences nuisance alarms for approximately 9 minutes (smoke must be present before Hush® is activated).
    • Test Feature – Simultaneously tests the unit’s electronics and verifies alarm operation.
    • Reset Feature – Resets the carbon monoxide alarm
  • Tamper Resist Feature – Unit will lock to mounting bracket to deter theft or tampering.
