What does a single chirp every 30 seconds mean?
This indicates a low battery. Replace the batteries immediately with fresh AA alkaline batteries.
Why is my CO120X beeping 4 times in a row?
This is the alarm pattern for carbon monoxide detection. Evacuate the premises and call emergency services. Do not ignore.
How do I test the alarm?
Press and hold the Test/Reset button until the alarm sounds (4 beeps, pause, repeat). Release the button. If the alarm does not sound, replace the batteries or unit.
How often should I replace the batteries?
Replace batteries at least once a year or when the low battery chirp begins. Use only AA alkaline batteries.
How long does the CO120X last?
The alarm has a 5-year lifespan from the date of manufacture. When it reaches end-of-life, it will chirp 2 times every 30 seconds and display 'End' on the screen. Replace the entire unit.
Can I install the CO120X in a kitchen or bathroom?
Avoid locations with high humidity or steam. Install at least 10 feet away from cooking appliances to prevent false alarms.
Does the CO120X detect smoke?
No, the CO120X is a carbon monoxide alarm only. It does not detect smoke or fire. For smoke detection, install a separate smoke alarm.
