About Carbon Monoxide Detectors


Carbon monoxide (CO) is a tasteless, odorless and invisible gas, but the effects of carbon monoxide poisoning can be deadly, which is why it’s often referred to as the “silent killer.” Carbon monoxide can be emitted from many household appliances including refrigerators, water heaters and space heaters. This is why carbon monoxide detectors are so important in a home. The detectors are designed to measure CO levels and sound an alarm if dangerous levels are found.

It’s important to note that carbon monoxide alarms and smoke alarms differ. Carbon monoxide alarms detect carbon monoxide gas while smoke alarms detect smoke created by fire. However, there are combo units available where one device can detect both carbon monoxide and smoke. There are even digital carbon monoxide detectors that allow you to see the levels of carbon monoxide in your home and observe if they fluctuate.

Carbon monoxide detectors are just as important as smoke detectors when it comes to home safety. If you find that your house could use more coverage, Ace has many options to choose from as well as a gas, smoke and fire protection guide so you can protect yourself and your family from this hazardous gas.
