Important public announcement (IPA)

The IPA alarm can be used when something serious has happened. For example, if a factory has caught fire and toxic smoke is spreading or if there is a risk of an explosion. If the important message concerns the area where you are, follow the instructions of the authorities.

You can receive IPA:s in several ways:

  • via outdoor alarm via the Hesa Fredrik horn (only for really serious events)
  • via radio and TV
  • via SMS to your mobile phone if used in the affected area
  • from Krisinformation.se via web, app and social media
  • as a notification in the Swedish Radio app SR Play, or via the SOS Alarm app 112.

In the event of really serious incidents, war and air raids, the Hesa Fredrik outdoor alarm can be used. It consists of around 4,500 horns located on rooftops or other tall buildings throughout Sweden. The horns are tested four times a year - at 15.00 on the first Monday in March, June, September and December. Hesa Fredrik has four different alarm signals.
