How to Ensure Your First Alert Carbon Monoxide Detector is Working Correctly

Ensuring that your First Alert carbon monoxide (CO) detector is functioning properly is crucial for the safety of your home and family. This article provides a comprehensive guide on how to check if your CO detector is working correctly.

1. Check the Power Supply

Whether your detector is battery-powered or hardwired, it is essential to verify the power supply. Here are the steps:

Battery-Powered: Ensure the batteries are fresh. Replace them if you are unsure when they were last changed. Most detectors will emit a specific beep pattern to indicate a low battery. Hardwired: These detectors are connected to your home’s electrical system but should also have backup batteries. Check these batteries the same way as you would in a battery-powered unit.

2. Test the Detector

Performing a test can help you confirm the operational status of your CO detector:

Use the Test Button: Press the test button to see if the alarm sounds. This test checks the electrical functionality and the sound mechanism but not the sensors' ability to detect CO. Listen for Beeps: The alarm should sound loudly to indicate that the electronic components and speaker are working.

3. Check the Expiry Date

CO detectors have a limited lifespan, typically between 5 and 7 years. Some newer models may last up to 10 years. Look for a manufacture date or an expiry date on the unit. If it has passed this date, replace the detector.

4. Optional Sensor Testing

Professional Testing Kits:

Some kits are available to safely expose the detector to a small amount of CO to see if it responds. Follow the manufacturer's instructions carefully.

Controlled Source Method (Not Recommended):

You could use a controlled source of CO, like a burning candle, held near the detector (not recommended without proper precautions and knowledge as it poses a safety risk and potential damage).

5. Visual Inspection

Vigilant visual inspection can help you identify any signs of damage or tampering. Ensure the detector's vents are not blocked by dust or paint, which can obstruct the sensors' ability to detect CO.

6. Check Manufacturer's Instructions

Refer to the user manual for specific maintenance guidelines and troubleshooting steps. Manufacturers may provide important information specific to the model you own.

7. Regular Maintenance

Regularly dust and clean the unit according to the manufacturer's instructions. Avoid using harsh chemicals or water that could enter the sensor.

8. Listen for End-of-Life Signal

Many newer CO detectors have a specific end-of-life signal, often a different beep pattern, to alert you when the detector needs to be replaced.

9. Professional Evaluation

If you suspect that your CO detector isn't working correctly even after these checks, consider having it evaluated by a professional or replacing it.

Regular Testing and Maintenance

Regular testing and maintenance of your CO detector are essential. It is a good practice to test your CO detector at least once a month and replace batteries annually if applicable or as soon as you hear the low battery warning. Always replace the CO detector unit itself before its expiration date.

Conclusion: By following these steps, you can ensure that your First Alert carbon monoxide detector is functioning correctly and providing peace of mind for you and your family. Regular testing and maintenance are crucial in maintaining the safety of your home.
