This pattern will continue every minute for at least seven days. One chirp followed by warning “LOW BATTERY.” The red LED light will flash. The alarm pattern will repeat until smoke is eliminated.įour short alarm beeps followed by a verbal warning “WARNING! CARBON MONOXIDE!” This continues until the unit is reset or the CO is eliminated. The red LED will flash and be accompanied by three long alarm beeps followed by a verbal warning message “FIRE!”. Photoelectric sensing alarms may detect visible fire particles (associated with slow smoldering fires) sooner than ionization alarms. Ionization sensing alarms may detect invisible fire particles (associated with fast flaming fires) sooner than photoelectric alarms. Leading authorities recommend that both ionization and photoelectric smoke alarms be installed to help ensure maximum detection of the various types of fires that can occur within the home. This constant communication enhances the alarm’s overall performance in all fires, and significantly reduces the potential for a nuisance alarm. Depending on what is detected, the alarm will adjust its smoke sensitivity in order to better discriminate between a real hazard and a false one. When either sensor notices a potential hazard, it will communicate with the other. Since carbon monoxide is present in all fires, having both detection chambers work together in one alarm is a breakthrough in the fire safety industry. The Intelligent sensor technology combines the detection capabilities of an ionization smoke sensor – which is more likely to detect smaller, less visible fire particles, like those produced by flaming fires – with that of an electrochemical sensor, which is used to detect CO. If the unit malfunctions, the red LED will flash and the unit will chirp every 30 seconds.The Kidde KN-COSM-IBA uses breakthrough technology to offer a fast response to real fires, including smoldering and fast-flaming, as well as protect you from carbon monoxide and dramatically reduce the chance of nuisance alarms.

Kidde smoke and carbon monoxide alarm install#
The 21006377-N is an easy to install alarm that is suitable for all living areas.

This technically advanced combination alarm includes 9V battery backup providing protection even during a power outage when many incidences occur. 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 includes a voice warning system that announces "Fire, Carbon Monoxide, Low Battery or Smart HushTM Activation". The Kidde 21006377-N Combination Carbon Monoxide & Smoke Alarm provides two important safety devices in a single unit.
