The Kidde KN-COSM-IBA uses Intelligent sensor technology combining ionization smoke detection and electrochemical CO detection. The two detection chambers communicate — when either senses a hazard, it signals the other. The alarm adjusts smoke sensitivity based on CO presence to better distinguish real fires from nuisance events. Voice warnings announce 'Fire!' or 'Warning, Carbon Monoxide'. Peak level memory alerts when CO concentrations of 100 PPM or higher have been detected. Hush button silences nuisance alarms. This model is replaced by the 30CUAR.
What makes the KN-COSM-IBA's intelligent technology different?
The ionization smoke sensor and electrochemical CO sensor communicate with each other. Since carbon monoxide is present in all fires, when the CO sensor detects CO, it signals the smoke sensor to increase its sensitivity. This allows faster detection of real fires while reducing nuisance alarms from non-fire smoke sources.
What replaces the KN-COSM-IBA?
Kidde recommends upgrading to the 30CUAR, the current DETECT hardwired combo alarm with AA battery backup, enhanced photoelectric sensing, self-testing, and updated UL certifications.
