X-Sense CO03A Battery Powered Carbon Monoxide CO Detector Sensor Alarm with Digital Display


Reliable Performance 

Carbon monoxide (CO) is invisible, odorless and yet lethally poisonous. The electrochemical gas sensor of this carbon monoxide alarm is highly sensitive at detecting carbon monoxide leaks and protects all your family against deadly threats. Also, the unit may detect dangerous CO levels when no one is at home. The highest CO concentration detected will be recorded and shown on the LCD screen. Please note that this alarm does not sense smoke, heat, flames, or other hazardous gas. 

Convenient Use 

The LED indicator on this alarm flashes in green every 50 seconds in the standby condition to confirm that the unit is functioning normally. The alarm sounds with a volume of up to 85 dB to alert all household members when it detects 30 ppm of carbon monoxide for 120 minutes, 50 ppm for 60-90 minutes, 100 ppm for 10-40 minutes, or 300 ppm for 3 minutes. The alarm will also automatically reset when the hazardous conditions have passed. 

Easy Installation 

This alarm comes with a mounting bracket, 2 screws and 2 anchor plugs, and can be easily hung on the wall in houses, apartments, mobile homes and dormitory rooms, or placed on any flat surface. We recommend that the alarm should be located between sleeping areas and potential sources of CO leaks such as living rooms and kitchens. Please refer to the user manual for detailed instructions.
