If your Honeywell alarm system fails to sound or respond, it may be because of a Comm Failure. A Comm Failure is an electrical issue with your alarm system that can prevent it from ringing or responding. To clear a Comm Failure, you will need to remove the battery and replace it with a new one. You will also need to reset the alarm system and check for any other issues. If all of these steps don’t fix the Comm Failure, you may need to call Honeywell customer service.
