Setting Up and Operating Your Kidde CO Detector
Proper installation and operation are key to ensuring your Kidde KN-COB-B-LPM detector works effectively.
Installation:
- Choose the Right Location: Install detectors in hallways outside of bedrooms and on each level of your home. For optimal protection, consider placing one near or in each bedroom. Avoid installing detectors in kitchens or bathrooms where normal cooking fumes or steam might trigger false alarms. Do not place in corners or close to windows or doors.
- Mounting: The Kidde KN-COB-B-LPM can be mounted on a wall or ceiling. Use the included mounting bracket and screws to secure it. Ensure it is firmly attached and will not fall.
- Initial Power Up: Install a fresh 9V battery. The detector will perform a self-test, and the green light should flash periodically, indicating normal operation.
Testing Your Detector:
- Regular Testing: It is crucial to test your CO detector weekly to ensure it is functioning correctly.
- Test Button: Press and hold the “Test/Reset” button. The alarm should sound loudly and then stop. If the alarm does not sound, check the battery and re-test. If it still fails, the detector may need replacement.
Understanding the Lights and Sounds:
- Green Light Flashing: Normal operation – the detector is powered and working.
- Red Light Flashing and Alarm Sounding (Beeping 4 times every 5 seconds): Carbon monoxide is detected. Evacuate everyone immediately and call emergency services from outside the home.
- Yellow Light Flashing and Chirping every 60 seconds: Low battery. Replace the battery immediately.
- Chirping every 30 seconds (even after battery replacement): End-of-life warning. The detector has reached its 10-year lifespan and needs to be replaced.
- White Flashing Light (in some models): Refer to the specific manual for your model, but it can sometimes indicate a detector malfunction or sensitivity issue.
Troubleshooting Common Issues and Alarms
Many users encounter common issues with their carbon monoxide detectors, often resulting in unnecessary concern. Understanding these issues can save you time and worry.
False Alarms:
- Possible Causes: False alarms can be triggered by temporary fumes from cooking, fireplaces, or gas appliances. Humidity and dust build-up can also sometimes cause false alarms.
- Silencing a False Alarm: Press the “Test/Reset” button to silence the alarm temporarily. Ventilate the area by opening windows and doors. If the alarm stays silent and does not reactivate, it may have been a temporary issue. If the alarm reactivates, evacuate and investigate the source of CO.
Persistent Chirping (Even with New Batteries):
- End-of-Life Signal: If your Kidde KN-COB-B-LPM is chirping even after replacing the battery, it is likely signaling the end of its 10-year lifespan. You must replace the entire unit immediately. Carbon monoxide detectors have a limited lifespan for safety reasons and sensor degradation.
- Incorrect Battery Type: Ensure you are using a standard 9V alkaline battery. Rechargeable batteries or other battery types may not provide sufficient power.
Detector Not Resetting:
- Automatic Reset: The Kidde KN-COB-B-LPM should automatically reset after the condition that caused the alarm is resolved and the “Test/Reset” button is pressed.
- Battery Issue: If it doesn’t reset, try replacing the battery again, ensuring correct polarity. If it still doesn’t reset, the unit may be faulty and require replacement.
Maintenance and Care for Longevity
Proper maintenance ensures your Kidde carbon monoxide detector remains reliable for its lifespan.
- Battery Replacement: Replace the battery at least once a year, or whenever the low battery chirp occurs. Use a fresh 9V alkaline battery.
- Cleaning: Dust and cobwebs can accumulate and affect detector performance. Gently vacuum the detector with a soft brush attachment every six months. Never use water or cleaning solutions.
- Do Not Paint: Do not paint over the detector as paint can seal the sensor openings and impair functionality.
- Replacement: Kidde KN-COB-B-LPM detectors have a 10-year lifespan. Replace your detector after 10 years from the date of manufacture, which is usually printed on the back of the unit. The end-of-life chirp will also signal replacement is needed.

Frequently Asked Questions About Kidde KN-COB-B-LPM
Q: How do I reset my Kidde carbon monoxide detector after replacing the battery?
A: The detector should automatically reset after installing a new battery and pressing the “Test/Reset” button.
Q: My CO detector keeps chirping even with new batteries. Is it broken?
A: Persistent chirping after battery replacement often indicates the detector has reached its end-of-life (10 years) and needs to be replaced.
Q: What does it mean when the red light is flashing and the alarm is sounding?
A: This indicates that carbon monoxide has been detected. Evacuate immediately and call emergency services.
Q: Can cooking fumes trigger my carbon monoxide detector?
A: While less sensitive to cooking fumes than smoke detectors, it’s best to avoid placing CO detectors directly in kitchens. However, if cooking fumes are excessive, they could potentially trigger an alarm. If false alarms are frequent and occur near the kitchen, consider relocating the detector slightly further away, while still ensuring it protects the living areas.
Q: Where is the best place to install a carbon monoxide detector?
A: Install detectors on each level of your home, especially near bedrooms and in hallways leading to sleeping areas.
