- It's super serious. In the case of fire smoke, a loud speaking alarm should start and then the routine will start, but now it did not, says Urban Wickman, Head of Operations for the upper secondary school in the municipality of Hudiksvall.

The rescue service was alerted and according to the municipality's techniques the alarm went off at the school as well. The Head of Operations for the Bromane Gymnasium and Urban Wickman were in the premises at the smoke development. He says that in this case, they had to rely on the emergency services because the technology did not work.

"Extremely surprising"

According to Wickman, the school had a fire practice as late as October 18, and then everything worked perfectly.

- It's incredibly surprising that it didn't work, says Urban Wickman.

During Wednesday morning the alarm was tested several times and then everything worked as it should. An investigation has now been added to find out what went wrong.
