ABSTRACT:
For giving assistance to persons living alone in closed dwelling units, an emergency call report is transmitted in a communication system from an alarm location to an allocated alarm central authorized to receive. Thereby, with mutual identification, the connection is automatically completed to the alarm central via a public telephone dial network. An intercommunication connection with the person seeking assistance is controlled by the alarm central. In case a helper must enter the closed dwelling, a monitored access for the helper can be rendered possible proceeding from the alarm central. Thereby, the access authorization is monitored and the dwelling door is opened as well.
