A combined alarm, security and rescue system includes room boxes (33a-33j, 35a-35j) in associated rooms, a two way communication system (29a-29C, 30a-30C, 31a-31b, 32a-32j, 34a-34j) between a number of room boxes and a central operator station, and a central operator station. The system can be used in hotels, hospitals, cruise vessels, offshore living quarter platforms, and other places where many people usually are gathered within a definite area. In case of an emergency situation, the system provides essential information at the operator station for rescue crew, and thus acts as a decision tool for the rescue leader. The system also provides personal safety equipment like breathing masks (contained in the room boxes), that can be used by the people in the rooms in order to break through areas filled with smoke. Further, necessary equipment for a person-to-person communication between the central operator and the people present in the actual rooms is provided. The communication system enables the central operator to give alarms and other messages to persons in one or more rooms, and to receive acknowledgements from the persons in the room(s). Finally, all events are time-stamped and recorded at the central operator station, so that investigators easily can reconstruct the progress of a disaster.
