What does an ERR message mean on my carbon monoxide alarm?

Oct 27, 2011

NOTE: An Err message may appear on your carbon monoxide alarm’s digital display for several different reasons.

Responding to an Alarm Malfunction

NOTE: In the rare event that your alarm malfunctions, it will alert you with a short Chirp and the Red LED will flash once every 30 seconds.

If your alarm is malfunctioning, perform the following steps:

  1. Push and hold the Test/Reset button for 5 seconds, and then release the button. NOTE: If the reset is successful, the display will reset to zero. If it's an actual malfunction, the unit will go back to Err within 5 minutes.
  2. If it does turn out that your alarm is malfunctioning after you reset it, you need to press and hold down the Peak Level button. NOTE: The Err message will change to a Err code. It will start with an E and have two numbers behind it.
  3. Once the error code is displayed, call us on our hotline at 1-800-880-6788, provide an agent with the code, and they will assist you further. NOTE: Please make sure that you have your alarm's model number, date of manufacture, and assembly number (if visible), so you will not have to call back.

Responding to a Power Surge

NOTE: A power surge may be the cause of an Err message.

If you think a power surge may have been the cause, push and hold the Test/Reset button for 5 seconds, and then release the button.

NOTE: If it was just a surge that created the Err message, the reset will change the display to zero and stay there.

Responding to an End-of-Life Warning

NOTE: An Err message may be due to an End-of-Life warning. Seven years after initial power up, this unit will Chirp every 30 seconds to indicate that it is time to replace the alarm.

WARNING: The unit will not detect carbon monoxide in this condition.

If your alarm has reached its End-of-Life warning, replace the alarm immediately. NOTE: For more information about your specific alarm, refer to your user’s manual
