The Kidde KN-COSM-B 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 or 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 KN-COSM-B is an easy to install alarm that is suitable for all living areas, has a 5 year limited warranty, and is UL approved.

Alarm Warnings

Fire: The red LED will flash and be accompanied by three long alarm beeps followed by a verbal warning message "FIRE! FIRE!". The alarm will repeat pattern until smoke is eliminated.

Carbon Monoxide: Four short alarm beeps followed by a verbal warning "WARNING! CARBON MONOXIDE!" This continues until the unit is reset or the CO is eliminated.

Low Battery: One chirp followed by warning "LOW BATTERY". The red LED light will flash. This pattern will continue every minute for the first hour. After the first hour the red LED light will flash once every minute accompanied by the chirp sound. The "LOW BATTERY" warning will only sound once every fifteen minutes.

Voice Hush Indication: "HUSH ACTIVATED" and "HUSH CANCELED" voice announcement.

Peak Level Memory: If the alarm had detected a CO level of 100ppm or higher, the unit will announce "CO PREVIOUSLY DETECTED" to warn of the CO incident, when the Test/Reset button is pressed.
