What @marktheknife said. 
In the US, a distinction is made between residential smoke alarms and multipurpose security alarms, particularly those for offices.
In the US, residential smoke alarms, from the first alert to nest protect to halo are not supposed to use their speakers for any other notifications, as the fear is that you might get a notification that the laundry was done and miss a smoke alarm.
Multi-purpose Alarm systems such as those used in offices don’t have the same restriction as they are supposed to be part of a system that also has a separate set of fire only alerts.
