Fire Alarm-Notification devices in Private offices

[VAC]

I did a quick search but came up empty.
Simple question, but Fire alarms/notification devices is not my area of expertise.
I'm am aware of the need for strobes in public and common use areas, and employees areas being wired in case it becomes required.
My question is, are (audible) notification devices (alarms without the strobe) required in private offices? all occupiable areas? and would that be spelled out somewhere?

I'm not trying to design an alarm system, I'm just trying to understand the basic requirements for the audible part/devices.~TIA

I don't know how I missed that under all the other exceptions! Thank you.

A hint for the rest of us: you can download a sound-measuring application onto your phone for *just* this purpose.
