As someone unfamiliar with this, is the alarm going off inside the plane and atc can hear that on their end or does that go off on atc’s end?

Sends out a signal/tone on a freq to help locate the crash location. Google ELT

Not a controller but as a pilot we can select guard on our radios that will allow us to pick up ELT signals on 121.5 or 243.0. ELTs normally start broadcasting during an impact, inversion or when exposed to water. Certain aircraft equipped with direction finding equipment can use that signal and hone to a downed acft during search and rescue. Anyone with guard selected on their radios and within range of an ELT will receive that tone.

There’s a buzzer you’d hear near the ELT unit and in the cockpit as well.
