2. How it works? The Munich city refugee centers are equipped with smartphones and TWIG Embody personal alarm devices. Both devices are connected to iTelematics Enterprise, the alarm receiving center, communicating within public telecommunication network. In an emergency case the smartphones carried by the center employees can be located inside the buildings with the help of installed iBeacons. The TWIG Embody devices are installed inside the buildings in predefined spaces. In every predefined space, two TWIG Embody devices in continuous power supply are fastened under a table permanently. Loud and silent alarm Depending on the situation, the refugee center employee can either launch a loud alarm or a silent alarm by pressing the SOS key of the under the table fastened TWIG Embody. To differentiate the devices from the functions, the left hand TWIG Embody is configured for the loud alarm and the right hand TWIG Embody is configured for the silent alarm. The left TWIG Embody with internal loud alarm frightens the aggressor and sends the alert message to the ARC. The right TWIG Embody with silent alarm discreetly calls the ARC and opens a silent call enabling to listen to the emergency situation. The ARC alerts the police according to its situational awareness. Fast help with accurate location In emergency situations all nearby employees are alerted automatically and immediately on their smartphones. The nearby colleagues of the aggressed employee receive the alert, including the position details, to their smartphones and can reach the person in distress fastest. The alarm receiving center operates with the iTelematics Enterprise alarm monitoring system (PNEZ) where all alarms are managed. The leading operator controls the incoming alarms and opens a handsfree call to the device launching the alarm. The silent alarm opens a hands-free call enabling the operator to listen to the situation in the room. If the operator sees it necessary, he alerts the police forces and informs it of the exact location of the event. The emergency alert in the ARC and personal alarm device will be closed only after the official closing of the process.
