If the alarm is in Fault mode, it will chirp every 30 seconds with a voice message: "Error, see troubleshooting guide." (Note: After 5 minutes the voice messages stop but the chirps will continue.) This could mean the alarm needs cleaning. Push the button once and count the number of red LED blinks. A fault code of 10 or 14 red LED blinks indicates cleaning is needed.
