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

Rated 1 out of 5 by Frequent falsing I hate these detectors with a white hot passion. I bought them for a retrofit in an old house. Now six months later, I'm shopping for a new brand to replace them all. They false very frequently: Both the smoke and CO functions. Maybe that's just reality with all resdiential smoke detectors. What makes the Kidde/Firex detectors uniquely annoying is that they don't have a silence button. They have a "hush" function that is supposed to turn down the sensitivity, but in practice often does nothing. It creates a situation where there's no way to silencing a falsing system without either unplugging the alarm or beating it to death. (I've done both) I would strongly recommend NOT buying Kidde/Firex detectors as they all seem to have this "feature". August 24, 2014
Rated 1 out of 5 by Junk 2am, way to frequently, FIRE FIRE. There is not a fire, shut up. False alarms all the time. I clean them. I replaced them. I sprayed bug spray to keep bugs out since that's what the company said was the problem. Nothing works. All of these are getting replaced in my house. October 3, 2014
