How to Know If Your Alarm is Malfunctioning Your alarm performs an internal self-diagnosis every 15 seconds to make sure that it is functioning properly. The alarm is designed to alert you in the unusual event of a malfunction.

If the alarm malfunctions.

In the rare event that your alarm malfunctions, it will alert you with one of these signal groups (depending upon the type of malfunction that occurs):

Malfunction Signal Group 1 - Component Failure

–An intermittent “chirping” alarm will sound every 30 secs., and

–An “Err” message will appear on the digital display

Low Battery Warning

If the 9V battery is missing, or if the battery’s power is low, an “Lb” message will display which blink’s alternately with the current CO reading or “GAS” every second. If this happens, you need to replace the battery. Refer to page 1-5 for more on low battery warnings.
