The automated public address announcement can be generated automatically by the station's fire warning system, or can be triggered from the station control. The message audio file is usually stored as the primary standard emergency announcement on the station PA/VA system. The message may indicate that a single fire alarm call point in a public area has been operated. If a fire alarm in a non-public area is operated or more than one fire alarm is operated or if a detector has gone off the system will start the evacuation procedure and the fire brigade is automatically called. The announcement can be triggered by the station controller to alert station staff of other incidents which need urgent attention. The automated nature of the announcement and its high priority means that it has occasionally been known to cut into manual (lower priority) announcements being made by station staff.

"Mr Sands" has long been used in theatres as a code for fire, where sand buckets were used to put out fires. The word "fire" backstage would cause alarm to either performers or audience.
