Smoke & Carbon Monoxide (CO) Detectors Explained
Smoke and carbon monoxide (CO) detectors are essential safety devices designed to alert you and your family from potential hazards. Smoke detectors are designed to detect smoke as an indicator of fire. They are crucial for early warning in case of a fire, allowing occupants to evacuate and seek safety. Carbon monoxide detectors monitor the air for the presence of carbon monoxide, a colorless, odorless gas that can be lethal in high concentrations. It is often produced by fuel-burning appliances like furnaces, water heaters, and fireplaces.
Note: A carbon monoxide (CO) detector is primarily used for safety concerns related to potential poisoning from fuel-burning appliances, whereas a carbon dioxide (CO2) detector is typically used to monitor indoor air quality and ventilation levels.
- Carbon monoxide is a fatal gas for humans and animals whereas carbon dioxide is the gas that humans and animals exhale.
- Although both gases are colorless and odorless, CO poisoning is much more common and usually isn’t detected until one has fallen ill; CO2 poisoning, on the other hand, is quite rare.
- Carbon monoxide is a flammable gas while carbon dioxide is not.
Signs You Need a New Smoke or Carbon Monoxide (CO) Detector
Smoke and carbon monoxide (CO) detectors are essential for your home’s safety, and while they typically last for about ten years, various signs can indicate it’s time to replace them. Here are five key signs to watch for:

Chirping Sounds
A non-stop chirping sound typically signals low batteries or a fault in the system. However, if the chirping continues despite battery changes, there could be a deeper issue, such as a malfunction in the detector itself.
Yellow Residue
Over time, bromine used in smoke and CO detection devices can leave behind a yellowish residue. This residue is an indicator that the device is nearing the end of its service life and needs replacement.
Testing Failure
If your detector fails to sound during testing or produces a muffled sound, it may no longer be able to effectively detect smoke or carbon monoxide and should be replaced.
Unexpected Activation
If your smoke or CO detectors are activating for no apparent reason, giving false alarms, it may be due to faulty sensors or internal issues. In this case, replacing the unit is often the best option.
Exceeded Lifetime
If your smoke or CO detector has been in place for over 10 years, it’s time for a replacement. Even though it may still be functioning, detectors lose effectiveness over time.
What Does an Electrical Smoke & CO Alarm Inspection Include?
When you choose Electrical Solutions of Central Arkansas for your smoke and CO alarm inspection, you can expect a thorough process designed to ensure your home’s safety. Here’s what we do during the inspection:
Detector Placement Evaluation
Our electricians will evaluate the placement of your smoke and carbon monoxide detectors to ensure they are positioned correctly. For maximum safety, detectors should be located near each sleeping area and on every level of the home.Battery Check
Once the placement is confirmed, we will check the current condition of the batteries in your detectors. Fresh batteries are essential to ensure your detectors function when needed.Functional Testing
We will test each alarm to ensure they are functioning correctly. This involves checking the sound and response to simulated smoke or carbon monoxide.Feasibility Assessment
After testing, our electricians will assess if the detectors are still in good working order or if they show signs of malfunction.Recommendations for Replacement
If we find that your detectors are no longer functioning properly or have reached the end of their useful life, we will recommend either replacing the batteries, repairing the devices, or installing new detectors to ensure your home is adequately protected.




Smoke & Carbon Monoxide (CO) Detector Installation Process
Ensuring that your home is protected from smoke and carbon monoxide (CO) hazards is a critical part of maintaining a safe environment. Here’s what you can expect during the installation of smoke and CO detectors by our experienced electricians:




Evaluation of Current Working Condition
Initial Inspection: If you’re replacing existing detectors, we’ll first inspect their working condition. This includes testing the functionality and checking for any signs of wear or malfunction. If the devices are outdated or not functioning correctly, we’ll recommend replacement.Determining the Best Placement
Optimal Location: Our electricians will work with you to determine the ideal placement for your new detectors. Smoke alarms should be installed on the ceiling, at least 10 feet from cooking appliances, and near sleeping areas. Carbon monoxide detectors should be installed in hallways or near sleeping rooms but not in the kitchen or garage.Choosing the Right Detectors
Detector Options: We offer a variety of smoke and CO detectors, including battery-operated, hardwired, and combination units. Our electricians will help you select the best detectors for your home’s needs, ensuring maximum protection against both smoke and carbon monoxide.Installing Hard-Wired Alarms
Hard-Wired Connection: If you’re opting for hardwired alarms, we will connect the detectors to the electrical system. This provides constant power, with a battery backup for reliability during power outages. The alarms will be linked together to ensure that if one sounds, all alarms in the system will activate.Installing Remodeling Boxes
Supporting Installation: For new installations or when installing hard-wired systems, a remodeling box will be placed into the drywall. This box holds the wiring and provides secure support for the detectors.Connecting Wires
Wiring the System: Our electricians will carefully run the necessary wiring from the detectors to the main circuit breaker. Once the connections are made, we will install the backup batteries for the alarm’s fail-safe operation.Testing the Detectors
Functional Testing: After installation, we conduct thorough tests to ensure the detectors are working correctly. We check for response time and ensure the alarms sound when triggered. If any adjustments are needed, we’ll make them on the spot to guarantee optimal performance.
Benefits of Installing Smoke & Carbon Monoxide (CO) Detectors
Installing smoke and carbon monoxide detectors in your home provides critical and affordable protection against two of the most common and dangerous hazards: fire and gas leaks. Here are some key benefits of having these life-saving devices installed:
Early & Quick Detection
Smoke and CO detectors give an early warning in the event of a fire or gas leak. By alerting you at the first signs of danger, these devices allow you to take action before a potentially disastrous situation escalates.
Night Protection
At night, when people are most vulnerable, these detectors offer protection. They ensure that you and your family are alerted to potential dangers while you sleep, providing an extra layer of safety and peace of mind.
Safety for Everyone
Smoke and CO detectors are essential for households with young children, elderly individuals, or anyone with mobility impairments. These devices provide an audible alarm that can alert those who are vulnerable or may have difficulty responding to emergencies, ensuring they have time to evacuate safely.
Safe Evacuation Time
When a fire or CO leak occurs, detectors help you implement your home’s emergency escape plan. Early alerts give you and your family enough time to evacuate the house and alert the proper authorities, minimizing harm and potential loss.
Continuous Protection
Whether you’re at home or away, smoke and carbon monoxide detectors ensure that your home is always monitored. This provides invaluable peace of mind, knowing that your family and property are safeguarded from these invisible threats.
Property & Health Protection
Detecting a fire early can significantly reduce the damage to your home and belongings. Similarly, detecting carbon monoxide leaks promptly can prevent health-related issues and costly repairs that may result from gas exposure.
