This is a combined smoke and carbon monoxide alarm. It uses photoelectric smoke detection and a high-performance electrochemical carbon monoxide sensor for dual detection. It can detect smoke particles in real time, with faster detection of visible particles (such as those produced by smoldering fires) than ionization-type smoke alarms.
The carbon monoxide sensor provides stable performance, low power consumption, high sensitivity, and a compact design. When smoke or carbon monoxide is detected, the red LED flashes rapidly and the alarm emits a warning sound to alert you and your family.
