Carbon monoxide is a colourless, odourless gas that can be extremely dangerous and even fatal if inhaled in high concentrations. It is released when a material burns (namely gas, oil, coal, and wood); homes with fuel-burning appliances or attached garages are more likely to have carbon monoxide issues.

As our senses cannot detect carbon monoxide, a carbon monoxide detector is essential for detecting its presence and protecting ourselves and our loved ones.

However, like any other electronic device, carbon monoxide alarms can deteriorate over time and become less effective. Therefore, knowing the signs indicating you should replace your carbon monoxide alarm is crucial.

The Alarm Is Reaching Or Has Exceed Its Lifespan

Carbon monoxide detectors have a limited lifespan, which ranges from 5 to 7 years, depending on the manufacturer. The sensor inside the alarm can degrade over time, resulting in reduced sensitivity or failure to detect carbon monoxide. As a result, if your alarm has reached or has exceeded its recommended lifespan, it is recommended that you replace it with a new one to ensure reliable and accurate detection.

Frequent False Alarms

Frequent false alarms may indicate that your carbon monoxide detector alarm needs replacing. While you can expect occasional false alarms due to low batteries or minor interference, persistent or random false alarms should not be ignored. These false alarms may indicate a faulty sensor or other internal issues jeopardising the device’s dependability. As such, it’s best to be cautious and replace the alarm immediately to ensure your family’s safety.

Malfunctioning Alarm/Expired Battery

Carbon monoxide detectors are typically powered by batteries. If you notice that your alarm is beeping due to a low battery, but replacing the alarm does not stop the beeping, it could mean the alarm is malfunctioning.

Furthermore, some alarms have a battery lifespan (1 to 5 years), after which you should replace the battery. If the battery is no longer functional, consider replacing the entire unit to ensure dependable performance.

Inconsistent Or Intermittent Beeping

Carbon monoxide alarms are programmed to emit a specific pattern of beeps when it detects carbon monoxide. If you hear inconsistent or intermittent beeping from your alarm, it could be due to a faulty sensor or other internal problems. In such cases, replacing the alarm is recommended to ensure the highest level of safety for you and your family.

Signs Of Physical Damage

Inspect your carbon monoxide alarm regularly for physical damage. Accidental knocks, drops, or moisture exposure can jeopardise the device’s integrity and prevent it from functioning correctly.

If you notice cracks, dents, or other visible damage, replace the alarm as soon as possible, as it may no longer provide accurate readings or sound an alarm when needed.

Expired Certifications

When purchasing a carbon monoxide alarm, it is crucial to ensure it meets the necessary safety standards and certifications. If your alarm lacks or has expired certifications, replace it with a certified and up-to-date model to guarantee its reliability and effectiveness.

As there is no Australian standard for CO alarms, we suggest choosing an alarm certified to EN50291 (the European standard) or UL2034 (the US standard).

Outdated Technology

Advancements in technology have led to the development of more sophisticated carbon monoxide alarms with enhanced features and capabilities. If your current carbon monoxide home alarm is outdated and lacks features such as digital displays, peak-level memory, or wireless interconnectivity, consider replacing it with a more advanced model that offers additional safety features and better peace of mind.

Carbon Monoxide Alarm Replacement FAQs

How Long Do Carbon Monoxide Detectors Last?

Carbon monoxide alarms have a limited lifespan, typically 5 to 7 years. However, the exact lifespan can vary depending on the specific model, manufacturer, and quality of the alarm. It’s essential to check the manufacturer’s guidelines or instructions for the recommended replacement interval.

Should I Replace The Battery Of My CO Alarm Or The Entire Unit?

Most carbon monoxide alarms have replaceable batteries. However, it’s important to note that CO alarms have a limited lifespan and that battery replacement might not address any internal issues or sensor degradation. If the alarm is nearing the end of its recommended lifespan or showing signs of malfunction, it’s advisable to replace the entire unit.

Why Is My Carbon Monoxide Detector Beeping Intermittently?

If your carbon monoxide detector is beeping intermittently, it could indicate several issues. Here are some possible reasons why:

  • Low Battery
  • End-Of-Life/Replacement Warning
  • Malfunction
  • Environmental Factors (cigarette smoke, humidity)

If your carbon monoxide detector is intermittently beeping, you should take it seriously and investigate the problem immediately. First, replace the batteries and see if the beeping stops. If the beeping continues, replace the detector or seek professional help to troubleshoot the problem.
