What’s the difference between a CO and Smoke detector


A CO detector and a smoke alarm are two different devices. A CO detector is used to detect carbon monoxide in the air, which is a colorless, odorless and tasteless gas. When fuel burns incompletely, it emits carbon monoxide. It can also leak from heating elements and appliances. This means that it’s important to have both kinds of detectors in your home.

The main difference between a CO and a Smoke detector is how they detect CO. Hardwired detectors are powered by an AC electrical circuit. They are recommended for new construction but don’t require any electrical wiring. Battery-powered smoke detectors are portable and use a nine-volt or AA battery to function. These batteries need to be replaced twice a year, though lithium batteries last for up to ten years. A CO detector plugs directly into an electrical wall outlet, but it’s not practical to plug one into the wall, unlike a smoke detector.

If you have a smoke detector and a CO detector, you’ll need to choose which one is right for your home. If you have a wood-burning stove or fireplace, you’ll need a CO detector as well. A CO detector will detect small smoke particles better, while a CO detector will detect large particles. It’s important to have both to protect your home from fire.
