About this item

Kidde's Combination Smoke and Carbon Monoxide Alarm protects against two hazards and features a voice alert to clearly notify which hazard it has detected thereby aiding in quicker evacuation of the home.


"The Kidde 900-0102 Combination Carbon Monoxide & 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 and Smart Hush® 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 7-year life and a 5-year limited warranty."
