For optimal safety, your carbon monoxide (CO) detectors should be strategically placed on every floor of your home, especially near sleeping areas and away from direct sources of combustion.
Carbon monoxide is a colorless, odorless, and tasteless gas that can be deadly, making proper placement of CO detectors crucial for early detection. Understanding where to put these essential devices ensures maximum protection for you and your family.
Key Locations for Carbon Monoxide Detector Placement
Effective placement of carbon monoxide detectors is vital for timely alerts. According to ADT and general safety guidelines, consider the following specific areas:
Near Sleeping Areas
- Outside of Each Bedroom or Sleeping Area: This is a primary location. Placing a detector just outside bedrooms ensures that occupants are alerted quickly if CO levels rise while they are asleep, providing precious time to evacuate.
- For homes with multiple sleeping zones, ensure each area is covered.
On Every Floor
- On Every Floor, Including the Basement: Carbon monoxide can spread throughout your home. Having detectors on each level—main floor, upper floors, and in the basement—provides comprehensive coverage and increases the likelihood of early detection, regardless of the CO source.
Specific Appliance and Garage Proximity
When placing detectors, it's crucial to consider potential CO sources and airflow patterns.
- Inside an Attached Garage: Garages, especially attached ones, can be a source of CO from vehicle exhaust or gas-powered tools. Placing a detector here helps monitor potential leaks before they spread into the living space.
- At Least 10 Feet From the Garage Door Leading to Your Home: While a detector in the garage is good, it's also important to have one inside your living space, specifically away from the direct entryway from the garage. This distance helps prevent false alarms from vehicle exhaust during brief garage door openings, while still detecting CO that might seep into the home.
- At Least 15 Feet Away From Gas-Burning Appliances, Like Fireplaces or Stoves: Placing detectors too close to these appliances can lead to false alarms due to transient CO emissions during startup or minor fluctuations. A distance of at least 15 feet ensures the detector accurately measures ambient CO levels rather than temporary spikes.
Summary of Placement Guidelines
| Location Category | Specific Placement Guide | Reasoning |
|---|---|---|
| Sleeping Areas | Outside of each bedroom or sleeping area | Early warning for occupants during sleep. |
| Home Levels | On every floor, including the basement | Comprehensive coverage throughout the entire dwelling. |
| Garage Proximity | Inside an attached garage | Monitors potential CO from vehicles/equipment in the garage. |
| At least 10 feet from the garage door leading to your home | Prevents false alarms from car exhaust, yet detects CO entering home. | |
| Appliance Proximity | At least 15 feet away from gas-burning appliances | Avoids false alarms from minor appliance emissions. |

General Tips for CO Detector Installation
- Follow Manufacturer's Instructions: Always read and follow the specific installation instructions provided with your carbon monoxide detector, as models can vary.
- Avoid Obstructions: Ensure detectors are not blocked by furniture, curtains, or other objects that could impede CO detection.
- Test Regularly: Test your carbon monoxide detectors monthly using the test button to ensure they are functioning correctly.
- Replace Batteries Annually: For battery-powered units, replace batteries at least once a year. For units with sealed 10-year batteries, replace the entire unit after 10 years.
- Don't Place Near Vents: Avoid placing detectors near heating/cooling vents, fans, or windows, as drafts can affect readings.
By following these guidelines, you can significantly enhance your home's safety against the silent threat of carbon monoxide.
