"2-IN-1 PROTECTION: Equipped with photoelectric and electrochemical CO sensors that work independently; notifies you immediately when dangerous smoke or CO concentration is detected, while minimizing false alarms; provides ultimate protection from 2 deadly threats, in one unit
"BUILT-IN BATTERY WITH 10 YEAR LIFE: Provides 10 years of continuous power with a built-in lithium battery; no need for constant battery changes or doubt if your detector is still working
"PRECISE, RELIABLE AND HIGHLY SENSITIVE: The X-Sense combined smoke and CO alarm has been completely redesigned; it will ensure that smoke triggers the alarm, instead of disturbances caused by 3 separate smoke samples from the surrounding air; a 360° ring of air inlets ensures complete detection without blind spots
"LED STATUS LIGHT: Informs you of the detector's operating status with its 3-color flashing LED status light (green LED indicates normal operation, red LED indicates alarm status, and yellow LED indicates an error), so you and your home can feel safe 24/7
"LARGE LCD DISPLAY: Displays the battery level and CO values in PPM (parts per million) from the surrounding air in real time, with an updated measurement every 10 seconds"
