Who rang the fire alarm?
What's more common out of the two "rang" or "sounded"?
"Rang" implies that there is actually some bell which somebody is (themselves) ringing. If the fire alarm is actually a physical bell which somebody needs to ring (for example, in a historical context, before they had modern fire alarms), then this makes sense. If we're talking about triggering an electronic alarm system, however, this verb doesn't make as much sense.
"Sounded" says essentially that somebody is making a sound or noise. Again, if somebody is physically ringing a bell or something, or they're calling out "Fire! Fire!" with their voice, etc, then "sounded" also works. Again, however, this verb isn't generally used with modern electronic alarms, etc.
("Sounding the alarm" can also be used metaphorically to just mean alerting people to a situation, without necessary any actual "alarm" device or system being activated.)
If we are talking about more modern alarm systems (where somebody starts them going but then they keep going on their own without anyone's help), then I think more commonly people would tend to use other verbs that reflect a "triggering" action, like:
Who triggered the fire alarm?
Who set off the fire alarm?
Who initiated the fire alarm?
In many cases, alarm systems are initiated by pulling on a little lever on the wall, so another common thing to say in those cases is:
Who pulled the fire alarm?
