The “silent killer”
Known as the “silent killer,” carbon monoxide (CO) is odorless, invisible, and lethal. According to the CDC, approximately 50,000 people in the U.S. go to the emergency room each year due to CO poisoning. A carbon monoxide detector is required by law to ensure the safety of everyone. In commercial buildings, carbon monoxide detectors are required in any spaces where there is an open flame, such as: HVAC units, warehouse heaters, hot water heaters, furnaces, stoves or other cooking appliances. If you know you do not meet these requirements, or if you’re unsure, it’s time to consult the professionals at ROS Electric.
Local fire officials and building officials are enforcing this law every day. Whether your inspector notes inadequate CO precautions, you’ve already received a violation or if you just want to make sure your system is set up properly, we’re here to help. Call ROS Electric today to discuss how to keep your office, facility or home safe and compliant with effective CO detectors.
Where do I install a carbon monoxide detector?
Deciding where to install your carbon monoxide detector can be tricky. Best practices require at least one detector on every floor. Proper placement of the device is critical to accurate carbon monoxide detection. The height of installation depends on the room configuration. For residences, the alarm should be close enough to bedrooms to rouse sleeping occupants. Because there are a lot of variables that determine where your carbon monoxide detector will work best, it’s best to consult an expert rather than trying to do it yourself.
Don’t leave the safety of your business and employees to anyone but the experts. Contacting ROS Electric for your carbon monoxide monitoring needs means you’ll receive a complimentary, expert review of your facility and full recommendation on the best CO system for your individual needs. Every space is unique. Our team understands that and during our consultation, we will identify the most effective position(s) for your detector(s) to alert you and your employees of CO buildup. Our licensed electricians work with your electrical system ensuring the detector will be in the proper place, regardless of how your facility is currently wired following all requirements set by law to keep everyone safe. We also advise on the benefits and drawbacks of combination smoke and carbon monoxide detectors, recommending the right combination for you. With ROS Electric, you can rest easy knowing you have the right system for your facility.
Not only will ROS Electric provide a free consultation and review your needs, but you can also expect a seamless installation. Don’t leave something so important to chance, trust the experts at ROS with decades of experience and thousands of projects.

How do carbon monoxide detectors work?
Carbon monoxide detectors sound an alarm when they detect harmful levels of airborne CO over time. Sensor mechanisms include:
- Biomimetic Sensors
- Electrochemical Sensors
- Metal Oxide Semiconductors
ROS Electric has extensive knowledge of these configurations and can recommend the best choice for your business, home or facility.

FAQs
Why is Carbon Monoxide so Dangerous?
Carbon monoxide forms when fuels like gas, oil, wood, or coal burn incompletely. It builds up indoors when appliances or ventilation systems malfunction. Because it can’t be seen or smelled, people often don’t realize they’re exposed until it’s too late. Early symptoms like headache, dizziness, or nausea may seem minor but can progress rapidly to confusion, unconsciousness, or even death. CO detection systems identify unsafe levels before exposure becomes dangerous, protecting building occupants from a serious or fatal event.
Where Should Carbon Monoxide Detectors Be Installed?
Placement is critical for accurate detection. At a minimum, one carbon monoxide detector should be installed on every floor of the building. In commercial buildings, detectors must be placed in any area where there’s an open flame or potential source of CO, such as mechanical rooms, boiler rooms, kitchens, or near furnaces, HVAC units, and warehouse heaters.
The exact mounting height and distance from appliances depend on the manufacturer’s instructions and room configuration. Because every space is unique, ROS Electric provides on-site evaluations to determine the optimal detector locations for comprehensive coverage and compliance.
How Do Carbon Monoxide Detectors Work?
Detectors sound an alarm when they detect a buildup of CO in the air over a prolonged period. They use one of several types of sensor technologies:
– Biomimetic Sensors: Contain color-changing gels that react to CO exposure.
– Electrochemical Sensors: Generate an electrical current when CO is present, providing reliable and accurate readings.
– Metal Oxide Semiconductors: Use chemical reactions on a heated sensor to detect CO.
Each option has advantages depending on the environment. ROS Electric’s licensed electricians can recommend the most effective system for your property’s layout and risk level.
Are Combination Smoke and CO Detectors Reliable?
Combination detectors can be an effective option in residential or small office settings, providing dual protection in a single unit. However, larger buildings and commercial facilities often benefit from dedicated CO detectors, which provide more consistent monitoring. ROS Electric evaluates each property’s needs and can advise whether separate or combination units make the most sense based on safety requirements, budget, and building design.
What Should I Do if I Fail a Carbon Monoxide Inspection, or I’m not sure if My Property Meets Code?
If your local fire or building inspector flags inadequate CO protection, or if you’re uncertain about your system’s compliance, it’s essential to act quickly. Violations can carry penalties, but more importantly, they signal a potential safety hazard. ROS Electric offers expert inspections, compliance reviews, and professional installation to ensure your property meets all safety regulations and detection requirements.
How Often Should Carbon Monoxide Detectors be Replaced or Tested?
Most detectors last between 5 and 7 years, although some professional-grade models may have a longer lifespan. Regular testing, typically performed once a month, is recommended to ensure the alarm is functioning properly. Batteries should be replaced at least annually unless your system is hardwired or features a 10-year sealed battery. ROS Electric can include testing and replacement as part of routine maintenance service to keep your system performing properly.
Keep Your Property Safe from the Silent Killer
Carbon monoxide detection is a life-saving requirement that protects everyone inside your building. Whether you’re installing new detectors, upgrading outdated systems, or addressing a recent inspection notice, ROS Electric is ready to help.
