Quick Answer

Medical alert systems generally work by giving the user a way to call for emergency help through a wearable device, in-home base system, mobile unit, or some combination of those tools.

When the button is pressed, or when automatic fall detection is triggered if available, the system connects the user to emergency support or monitoring assistance.
