Acknowledging, silencing, and resetting FACP's

This is for a video that I’ve been working on for a while (this is a video that will be posted to one of my non-FA channels).

Can somebody point me in the right direction as to who is authorized to acknowledge an alarm condition, silence the alarms, and do a system reset on actual fire alarm systems?

I am aware that it depends on local laws and/or some other criteria, but I need some ideas for this video I’m working on.

The video in question is technically a work of fiction, but I feel that I need some realism in this.
