Exposure to carbon monoxide (CO) gas can occur when charcoal, wood, propane, natural gas, or oil are being burned. CO has no odor or taste, making it impossible to tell if you are breathing it in. This invisible gas will dissipate in most cases, but gas leaks in your home or garage can be fatal. By installing carbon monoxide alarms, you will be alerted as soon as CO is detected. It is recommended that carbon monoxide detectors be placed on every floor of your home or business, including in these areas:

  • Within 5 to 20 feet of a furnace, fireplace, or water heater
  • Basement
  • Laundry Room
  • Hallways
  • Kitchen
  • Living Room
  • Bedrooms

Types of Carbon Monoxide Alarms

There are three types of sensors that carbon monoxide detectors use to sense CO. Alarms with biometric detectors use gels that absorb CO in the air. The alarm will sound once a certain threshold is met. A metal oxide detector uses silica chips. This sensor detects when CO comes into contact with the chips and sounds the alarm. Electrochemical sensors detect CO by sensing changes in electrical currents using electrodes in chemical solution. As soon as CO is detected, the alarm will sound.

How to Install Carbon Monoxide Detectors

Carbon monoxide alarms can be installed several ways. Hardwire carbon monoxide detectors are hard wired to the buildings power. These alarms can be connected to multiple devices for additional warning time and use a battery backup. Older homes built before 1992 aren't generally required to have hardwired alarms, but check your local regulations to make sure. Plug-in, or AC powered, alarms plug directly into an outlet that is not operated by a wall switch. These alarms require no wiring and have a battery backup. Battery operated carbon monoxide alarms operate solely on a sealed Lithium powered cell that lasts up to 10 years. When the power cell fails, you replace the entire alarm. These tamper-proof alarms are required by law in several states including California and are ideal for rental homes and apartment buildings.

Carbon monoxide alarms should be replaced every 5 to 7 years. Detectors should be tested often, at least once a month, to ensure that the alarm is working properly. When the low battery chirp sounds, batteries should be replaced as soon as possible.
