On Monday 7 March at 15:00 there will be a scheduled test of Sweden’s emergency warning system, "Important public announcement" (IPA).
Sweden has a warning system called Important Public Announcement. The warning system includes outdoor signal horns or sirens. The outdoor warning system is tested at 15.00 (3 pm) on the first non-public holiday Monday in March, June, September, and December. The signal will sound for 7 seconds, with 14 second breaks, for a total of 6 times. Afterwards, the “danger over” signal is also tested, which is an uninterrupted 30-second signal.
