Method and devices for reporting emergency calls and for initiating emergency assistance measures
First Claim
1. In an emergency assistance system,an alarm central for monitoring for incoming emergency call reports (NRM) and operable to transmit coded signals including a coded communication control signal, a coded preliminary signal (TKF) and a coded door access signal (T0), and operable to send and receive voice communications,an alarm location for installation in a closed dwelling unit and having communication means providing for the reception of said coded signals from said alarm central and for two-way voice communication with said alarm central,an emergency call report device at said alarm location for initiating the transmission of an emergency call report to said alarm central via said communications means, when a person at the dwelling unit actuates said device to signal a need for emergency assistance,said communication means at said alarm location being responsive to the coded communication control signal from said alarm central for automatically establishing two-way voice communication between said alarm central and said alarm location via said communications means, whereby said alarm central can respond to an emergency call report by establishing voice communication with the person in need of emergency assistance, anddoorbell response means for connection with a doorbell of the closed dwelling unit, and responsive to said coded preliminary signal (TKF) from said alarm central, and operable after receipt of said coded preliminary signal (TKF) to notify said alarm central when the doorbell is thereafter actuated, so that alarm central is notified when a person summoned to render assistance has actuated the doorbell, anddoor access control means at said alarm location and automatically responsive to said coded door access signal from said alarm central for enabling access to the dwelling unit, whereby said alarm central has selective control of access to the dwelling unit and can authorize access after notification via the doorbell response means.

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.

1. In an emergency assistance system,
an alarm central for monitoring for incoming emergency call reports (NRM) and operable to transmit coded signals including a coded communication control signal, a coded preliminary signal (TKF) and a coded door access signal (T0), and operable to send and receive voice communications, an alarm location for installation in a closed dwelling unit and having communication means providing for the reception of said coded signals from said alarm central and for two-way voice communication with said alarm central, an emergency call report device at said alarm location for initiating the transmission of an emergency call report to said alarm central via said communications means, when a person at the dwelling unit actuates said device to signal a need for emergency assistance, said communication means at said alarm location being responsive to the coded communication control signal from said alarm central for automatically establishing two-way voice communication between said alarm central and said alarm location via said communications means, whereby said alarm central can respond to an emergency call report by establishing voice communication with the person in need of emergency assistance, and doorbell response means for connection with a doorbell of the closed dwelling unit, and responsive to said coded preliminary signal (TKF) from said alarm central, and operable after receipt of said coded preliminary signal (TKF) to notify said alarm central when the doorbell is thereafter actuated, so that alarm central is notified when a person summoned to render assistance has actuated the doorbell, and door access control means at said alarm location and automatically responsive to said coded door access signal from said alarm central for enabling access to the dwelling unit, whereby said alarm central has selective control of access to the dwelling unit and can authorize access after notification via the doorbell response means.

15. Method for reporting emergency calls and initiating emergency assistance measures by means of protected, coded data transmission between one or more alarm centrals authorized to receive emergency calls and at least one alarm location via a communication network, the alarm location being installed in a closed dwelling unit and having an emergency call report device which is normally in a reset condition, and an emergency assistance communication unit allocated to it whereby, on the basis of an emergency call report which results in a set condition of the emergency call report device, a connection to the alarm central is automatically completed and, by means of previous, mutual identification, it is assured that the emergency call and further information are only transmitted to the authorized alarm central, characterized by the following method steps:
-
(a) after the alarm location (MS) responds to an emergency call report (NRM) and transmits an emergency call to the alarm central (AZ), a communication connection for two-way voice communication is produced between the alarm central (AZ) and the alarm location (MS), said two-way voice communication via said communication connection being controlled from the alarm central (AZ); (b) a controlled door opening procedure is initiated by the alarm central (AZ) by transmitting a coded signal (TKF) for activating a door opening control circuit (TSK, FIG. 2;
TKSK, FIG.
3) to the alarm location (MS) and, after termination of the voice communication, the connection is disconnected;(c) after actuation (TKB) of a doorbell button (6) of the closed dwelling unit, a connection from the alarm location (MS) to the alarm central (AZ) is again produced by the activated door opening control circuit (TKS, FIG. 2;
TKSK, FIG.
3), and the actuation of the doorbell button is reported to said alarm central;(d) an access authorization of a person coming to assist is monitored by the alarm central (AZ) by means of a door voice and/or data transmission device (17) arranged at the door of the closed dwelling unit; (e) after determination of authorization, the opening of the door (8) is brought about from the alarm central (AZ) by means of a further coded signal (T0); and (f) after manual resetting of the emergency call report device at the alarm location (MS) a last connection with the alarm central is produced by the alarm location (MS) in which this resetting is reported by coded signals and is printed out in the alarm central to indicate that no further aid is needed, and the connection is released. - View Dependent Claims (16, 17, 18, 19)
