Battery Operated Wireless Smoke & Carbon Monoxide Alarm
900-0225CA


Provides protection from two hazards – fire and CO – Interconnects without wires, when one alarm sounds they all do.

  • Wireless Communication – Offers the safety benefits of an interconnected system without having to run new wiring.
  • Wink compatible – This product is compatible with the Wink Hub and the Wink App* and will send notifications to your smartphone, tablet or PC (Wink Hub required). Please see Wink Hub documentation for instructions. The Wink Hub is required to send notifcations to smart devices, but this alarm can operate wirelessly, with or without the Hub.
  • Voice Alarm – Announces the hazard type thereby helping to speed up the correct reaction to the hazard detected. Alarm announces “Fire!” when a smoke or fire hazard is detected and announces “Warning Carbon Monoxide” when a CO hazard is detected.
  • Combined Carbon Monoxide and Smoke Alarm – A single unit can be installed where previously, two were needed. Reduces installation time and helps to keep home décor attractive.
  • Peak Level Memory – If the alarm has detected a CO level of 100ppm or higher, the unit will announce “Carbon Monoxide Previously Detected” to warn of the CO incident, when the Test/Reset button is pressed.
  • Silent Mode Feature – Temporarily silences nuisance alarms.
  • Test/Reset Button – Tests alarm circuitry and triggers the voice announcement.
  • LEDs – Flashing green for normal operation and flashing red for alarm condition.
  • Battery Powered – Provides protection even during power outages when many fire and carbon monoxide incidents occur.
  • Low Battery Silence – Disable low battery chirp for 10 hours without disconnecting power from alarm
  • Ionization Smoke Alarm Sensor
  • cUL Listed

The Kidde KN-COSM-B-RF-CA (P/N 900-0225CA) Combination Smoke & Carbon Monoxide Alarm provides two important safety devices in a single unit. This alarm includes a voice warning system that announces “Fire”, “Warning, Carbon Monoxide”, “Low Battery”, and “Caution, Carbon Monoxide Previously Detected.” The voice alarm eliminates any confusion and clearly warns you and your family of a smoke or carbon monoxide danger, or if your battery is in need of replacement.  

This alarm can be installed as a single unit, or in a multiple station configuration that will enable wireless communication with the other alarms in the case of a smoke or CO event. Installation of the interconnect system is quick and easy, and avoids the hassle of extensive wiring and labor. Per NFPA guidelines, the interconnected system should not exceed the limit of 12 smoke alarms, or 24 total devices.
