Hardwired Combination Carbon Monoxide & Smoke Alarm KN-COSM-IBA
The KN-COSM-IBA Combination Smoke and Carbon Monoxide Alarm is an advanced, hardwired safety device designed to protect homes from two major hazards—fire and carbon monoxide (CO)—in a single integrated unit. It operates on 120V AC power with battery backup, ensuring continuous protection even during power outages.
This alarm features intelligent dual-sensor technology, combining an ionization smoke sensor and an electrochemical CO sensor. The ionization sensor responds quickly to fast-flaming fires, while the electrochemical sensor accurately detects carbon monoxide gas, providing comprehensive home safety coverage.
What makes this model unique is its interconnected intelligent communication system, where both sensing chambers work together. When one sensor detects a potential hazard, it communicates with the other to optimize sensitivity and reduce nuisance alarms while maintaining fast response to real threats.
The system is designed to distinguish between real emergencies and false triggers, improving overall reliability and reducing unnecessary alarms. This makes it especially suitable for modern residential environments where both fire types and CO risks are present.
The unit also provides alarm memory functionality, alerting users if carbon monoxide levels of 100 ppm or higher were previously detected, ensuring awareness even after the event has passed.
Built for long-term safety performance, the KN-COSM-IBA is UL Listed and widely recommended for homes requiring dual-protection systems.
