Handicap toilet alarm
The alarms on the handicap toilets on the X2000 trains goes directly to Crystal Alarm. The alarms are sent to everyone working on board the particular train. If on board personell are unable to stop the alarm, it is automatically escalated to the traffic control center.
At the traffic control center
The traffic control center receives all the alarms at their control rooms in Stockholm and Gothenburg. If there is a problem with the connection in one of the control rooms, all alarms are automatically prioritized to the other room.
Alarm to colleagues
All alarms are also sent directly to all colleagues on the same train. This allows the exposed person to get help faster. The link is made through an integration against SJ's planning system.
With the phone's GPS
The staff on the traffic control center and the colleagues can see which train the person is currently assigned to, they can also see the position which can be displayed on a map.
Easy to assess the situation
When someone triggers an alarm, the phone's microphone automatically activates and allows the traffic control center to listen in on the background sound. The function is a great help in assessing what action is required.

IT DevelopmentThe personal alarm works very well for us. Historically, we have had a lot of false alarms, but with the introduction of dedicated alarm buttons, the false alarms has decreased significantly. Our staff also feel more secure with the new alarm method. Crystal Alarm is helpful and helps exemplarily in all the issues and challenges that appear. I highly recommend the Crystal Alarm.

SJ IT SOAReal-life situation The train was on its way to Stockholm from Malmö and at the height of Hässleholm, there was a fight on board when two people were rejected without a ticket. One SJ staff felt so threatened that she pushed her Crystal Button. The alarm worked like clockwork, the system worked fully with positioning, emergency call to emergency telephone and SMS to other staff. Our own alarm routines worked and we executed the entire alarm chain. Police arrived at the station in Hässleholm in 6-7 minutes and we had direct contact with the Police's central in the South while we were listening to the person who triggered the alarm.
