Skyresponse:alarm is designed to give lone workers or private persons, who is at risk at ending up in unsecure environments or emergency, a possibility to quickly send off an alarm if you for example are under threat or has been injured in an accident. Skyresponse:alarm safely connects the alarm to a predefined receiver (could be a professional response centre, an internal operations centre or similar) which makes it possible to quickly initiate help. An alarm can be activated from the alarm button in Skyresponse:alarm application or via the wireless accessory called Safeclick. When an alarm is activated, a phone call is connected to the predefined receiver at the same time as the application transmit the exact location, user information and other status information from the phone to the response centre. The user information is combined with the pre-entered instructions in the Skyresponse system so that the operator receives an as accurate and distinctive picture as possible about the measures that is needed to be done. On the contrary to most other applications that send alarm to friends, Skyresponse:alarm normally sends the alarm to a response centre. The connection to the response centre goes through the Skyresponse system. Please contact Skyresponse to get a full list of professional response centers that support Skyresponses products. To be able to use Skyresponse:alarm, the user needs to have an account on Skyresponses server where the user has added their profile and the instructions that should be performed when an alarm is triggered. To best aid a rescue team locating the person in distress, continued updates as well as a history of previous locations are provided to the response center while the alarm is active. This app uses the GPS in the background when there is an active alarm. Continued use of GPS running in the background can dramatically decrease battery life.
