What is carbon monoxide and why is a carbon monoxide (CO) alarm essential for homes, apartments, and travel?
CO is a colorless, odorless gas from fuel-burning appliances. Build-up can occur from faulty furnaces, blocked vents, or running vehicles. Since some hotels and vacation rentals lack CO alarms, always travel with a portable Kidde detector.
What type of backup batteries should I use?
Only use alkaline Energizer E91, Gold Peak 15A, or Golden Power GLR6A. Lithium batteries should not be used.
How many carbon monoxide alarms do I need in my home?
Experts recommend installing a detector on every floor, including the basement, and in or near each sleeping area, ensuring full-home coverage and faster detection no matter where a leak occurs.
What should I do if my CO alarm goes off?
If the alarm sounds, evacuate to fresh air immediately and call 911. Do not silence the alarm or try to locate the source yourself; professionals should inspect for leaks or faulty appliances.
Do CO alarms expire, and how long do they last?
Yes, carbon monoxide alarms should be replaced every 5-10 years. Check the manufacturer's replacement guidelines. Kidde CO alarms offer 10 years of 24/7 detection.
