Abstract
The present disclosure relates an evacuation management system, EMS, () operative to provide real-time evacuation information for evacuation of a building, triggered by alarm notification (S). Based on determined (S) precise real-time positions of personal ultra-wide band, UWB, devices, as determined by UWB real-time localization system, RTLS, a controller determines (S) evacuation plans being personal UWB device specific in real-time. Based on individual evacuation plans and input from building facilities, real-time guidance information is defined (S) and sent to each personal UWB device, providing guidance to person carrying said personal UWB device, in what direction to move (S), to reach a safe area. Based on localization signals the UWB RTLSA then calculates updated positions of the personal UWB devices and sends to the evacuation management system. It is an advantage that trapped or injured people can be found, even in low visibility areas.
