The municipality of Trolhättan began to notice the problem at the beginning of the week, when several of the elderly who use the security alarms heard that the help had been delayed.

According to Jane Johansson, head of the care administration in the City of Trollhättan, the response time has at most been extended by one and a half hours.

- It is obviously a big problem, fortunately there have been no serious incidents, but there is obviously a risk of it if the problem is not fixed soon, she says.

What are you doing now?

- We are attentive and have extra supervision.

Everything is very unclear at the moment.

We have not received a good response from the supplier about what caused the problem, how we should do to deal with it or when it will be fixed, says Jane Johansson.

Problems in several municipalities

It is the company Tunstall that delivers the alarms and the problem has arisen since they changed the technology platform.

Municipalities throughout the country have noticed the disturbances and in Västra Götaland, in addition to the municipality of Trollhälltan, Munkedal, Lysekil and Sotenäs municipalities have been affected, according to information to P4 Väst.

SVT has contacted the company Tunstall for a comment.
