How it works Steps Press the alarm button on the device: it knows your exact location gathered via GPS satellites. It immediately sends an SMS with the location and ID information via the mobile phone network to our Emergency Response Centre and opens a 2- way audio link. The Emergency Response Centre controller listens to activity at your location, while seeing your details and location on a special screen. He evaluates and verifies the alarm and calls the appropriate emergency service if required - talking to you only if appropriate. Response service comes to your assistance - either the emergency services or Skyguard's own national response service depending on the circumstances.
