A carbon monoxide (CO) alarm is a simple yet essential component of any home, and it’s often overlooked. But do you know how to test it properly? Knowing how to check that your alarm is working correctly could be the difference between life and death. Read on for expert advice that could save your life.
What is a Carbon Monoxide Detector?
A carbon monoxide detector should be installed in every home or business that burns gas as fuel. Carbon monoxide is an invisible, odorless, and colorless gas that’s incredibly dangerous. If left undetected, it can be fatal. It binds with red blood cells in your body, depriving your lungs of oxygen, which can lead to severe health consequences or even death.
Early symptoms of carbon monoxide poisoning include headaches, nausea, dizziness, confusion, and shortness of breath. But it’s far safer—and easier—to prevent this danger with the right safety measures. Installing and regularly testing your carbon monoxide detector is a simple and affordable way to protect your loved ones.
If you don’t have a CO detector yet, and your home uses gas appliances like central heating, cooking hobs, or water heaters, install one now! CO alarms are available at most DIY stores and online.

How to Test Your Carbon Monoxide Alarm
Testing your carbon monoxide detector is vital to ensure it’s working and ready to protect your home. Follow these steps to ensure your detector is functioning properly:
- Check the Placement:
Ensure the detector is placed at least 1 meter away from any fuel-burning appliance (like gas boilers, fires, or stoves) and ideally 1½ meters from the floor. Since carbon monoxide is lighter than air, it accumulates in the warmer air near the ceiling. - Test the Alarm:
Most carbon monoxide detectors feature a test button. Push the button, and you should hear a series of four beeps followed by a brief pause. This confirms that the alarm is functioning. This is the safest and most reliable way to test your carbon monoxide alarm.
- No Beeps?
If you don’t hear any beeps after pressing the test button, press it again. If there’s still no sound, the detector may be malfunctioning.
- Replace the Battery: If the detector emits a low battery warning beep, it’s time to replace the battery. If it still doesn’t work after changing the battery, the device may need to be replaced.
- Regular Testing:
It’s important to test your CO alarm monthly to ensure it’s functioning properly, so it’s always ready to protect you.
Can I Test My Carbon Monoxide Detector with a Candle?
While some may suggest using a candle to test your carbon monoxide alarm, this is not recommended. Lighting a candle near the detector may expose you to unnecessary risks and doesn’t guarantee an accurate test. The test button on your device is designed to accurately verify its functionality, ensuring both safety and reliability. Always use the test button for an accurate and safe check.
How to Check for Carbon Monoxide in Your Home
The only reliable way to check for carbon monoxide in your home is through a carbon monoxide alarm. If you suspect a CO leak or your detector sounds, don’t hesitate to act.
Signs of Carbon Monoxide Poisoning:
- Headaches
- Nausea and dizziness
- Confusion or shortness of breath
If anyone is showing symptoms of poisoning, immediately evacuate the building and contact emergency services. Carbon monoxide can be life-threatening, which is why detection and prevention are essential. Regular appliance checks, gas safety certificates, and visits from qualified professionals can all help improve safety in your home.
What to Do If the Carbon Monoxide Alarm Goes Off (Not During Testing)
If your carbon monoxide alarm goes off, don’t panic—act quickly! The detector is warning you of a dangerous build-up of carbon monoxide in your home. Follow these steps immediately:
- Evacuate:
Get everyone out of the house, including pets. Move to fresh air outside. - Check for Symptoms:
Assess if anyone is showing signs of carbon monoxide poisoning, such as headache, dizziness, nausea, or confusion. - Call Emergency Services:
If anyone has symptoms of poisoning, call emergency services immediately. If no one is showing symptoms, you should still contact professionals to inspect the source of the leak.
Remember, carbon monoxide poisoning is a real threat, causing 60 deaths per year in the UK. Always treat an alarm seriously and act fast.
Why is Regular Testing So Important?
Testing your carbon monoxide alarm isn’t just a one-time task. It’s crucial to do so regularly, at least once a month, to ensure that your alarm is working properly. A faulty alarm is like having no alarm at all.
Key Benefits of Regular Testing:
- Protects Your Family: Ensure your detector is always ready to detect any potential CO leaks.
- Prevents Costs from Replacement: Spot issues early with regular checks so you can avoid costly emergency repairs.
- Peace of Mind: Testing regularly reduces the risk of false alarms, ensuring that your family is safe from carbon monoxide exposure at all times.
