What if you have a shed near your house and if something catches on fire out there you want to hear a smoke alarm inside your house where you might be sleeping but it is far enough back there you might not hear it.  A stand-alone super loud alarm might work but one with a radio transmitter to inside might work better.  I don’t recall ever having seen one like that.

Search for smart smoke alarms - they send a message to your phone.
Or wireless interconnected smoke alarms - when one goes off, they all
go off, range up to about 50 meters.
