About First Alert Carbon Monoxide Detector Alarm|No Outlet Required with Digital Display
Overall Feedback:
74% positive
64% praised for its accurate co detection, but 36% experienced false alarms
I appreciate the digital display feature of the detector, especially for carbon monoxide detection, as it is the only way to detect it.
I have learned that a good CO detector should sound at readings of about 70ppm, even better at 30ppm, and the alarm will sound within 15 minutes of a 400ppm reading, which is well above lethal levels of CO.
64% appreciated the clear and easy-to-read display
The display on my CO detector shows the amount of CO in the air, which is nice to have as a digital reading.
I like the digital display of this carbon monoxide detector as it is the only way to detect carbon monoxide.
76% found it easy to install
The installation was easy and required no electrical connection. It only needed two screws in the wall to hang on.
The carbon monoxide detectors were easy to install and came attractively packaged.
