Did you test if the alarm sounds when it is triggerred?
Check your manual for the resetting the system. Most probably the warning beep has been set to mute meaning you won't hear any beeping noise.
I could not find any reference for the system so I am not able to tell you how. Check the owner's manual for the resetting the system.
The other possibility is a failed or disconneted beeper.
