They have an alarm

On the newer MFD's with Bluetooth media player control, it's conceivably possible that a future Lighthouse software
update could include a Bluetooth profile which would allow playing an alarm
through at Bluetooth speaker or stereo system, but a hard-wired alarm is the more reliable option.
