The Kidde KN COSM B Combination Carbon Monoxide and Smoke Alarm provides two important safety devices in a single unit. This alarm includes a voice warning system that announces Fire, Carbon Monoxide, Low Battery or Smart HushTM Activation. 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 technically advanced combination alarm is battery operated protecting you and your family even during a power outage when many incidences occur. The 900-0102 is an easy to install alarm that is suitable for all living areas and has a 5 year limited warranty.

  • Talking alarm - announces the hazard type detected
  • Test/reset button - tests alarm circuitry and triggers the voice announcement
  • Combined carbon monoxide and smoke alarm - a single unit can be installed where previously, two were needed and reduces installation time and helps to keep home decor attractive
  • Two LED's are provided, flashing green for normal operation and flashing red for alarm condition
