Frequently asked questions

Where should I place a carbon monoxide detector?
The CDC and most fire safety agencies recommend a CO detector on every level of the home and outside each sleeping area. Plug it into a wall outlet that is not blocked by furniture or curtains so the sensor and display are unobstructed.

How long does a carbon monoxide detector last?
Most CO detectors are rated for 5 to 10 years of sensor life. Check the unit periodically with the test button and replace the detector when it reaches the end-of-life signal listed in the included instructions.

What is the difference between a CO detector and a smoke detector?
A smoke detector reacts to particles from fire. A CO detector reacts to carbon monoxide gas, which is invisible and odorless. Most homes need both because they sense different hazards.

Can I test the alarm?
Yes. Press the test button to confirm the alarm sounds. Run the test on a regular schedule, for example once a month, to make sure the detector is working.
