Ruotsi-Sweden (SE) 7801578-1 (71) Oy LM Ericsson AB, 02420 Jorvas, Suomi-Finland (FI) (72) Karl-Magnus Andersson, Tyresö, Tage Vilhelm Leander Andersson, Enskede, Ruotsi-Sweden (SE) ( 7) »Kolster Ab (54) Alarm system comprising a number of subscriber apparatus and a subscriber apparatus serving alarm center - Hälytysjärjestelmä, joka käsittää useita tilaajakoneita ja tilaajakoneita palvelevan hälytyskeskoken

The object of the invention is that, e.g. for pensioners and people with severe disabilities, facilitated in an emergency, that is, when they cannot normally use their telephone, alert a call center, where few can speak to anyone and if needed they can quickly get help.

The invention of the invention is based on the fact that pensioners usually live in their own apartments, confined in urban or rural buildings and where available to ordinary telephone equipment. The pensioners have different health status and can in their homes live out for accidents, acute illnesses or towers, assaults. In this case, it may be difficult or impossible for them to use their telephone to call for help.

Alarm systems are known in the past, with which the needy can call attention, ie. say "alarm", but a simple alarm gives many ginger no information on what has occurred (or perhaps occurred in cases where only a pure contact need exists). If the alarmist lives at a significant distance, perhaps kilometers or miles, from auxiliary municipal agency (hospital, hospital, fire station, police station), alarm ginger can unnecessarily cause an emergency call with a police or medical car to get information about what has happened. . By adding voice communication to the alarm function in accordance with the invention in a certain way, the advantage that the cost of calling in blind can be completely eliminated.

Speaking voice communication means that the bed- or floor-lying person can, after alarm alerting from his place, without his own measures regarding the telephone apparatus, be addressed and respond in that they are centrally fir knowledgeable about what has happened. This is done in such a way that unauthorized eavesdropping cannot occur, ie. the non-grity of the aid applicant is fully secured.

The characteristics of an alarm system according to the invention appear from the appended claims.

An alarm system according to the invention comprises a plurality of subscriber apparatus and a subscriber apparatus serving alarm center. The subscriber sets each include, in addition to traditional telephony equipment, an automatic dialing device, a microphone speaker and a first switching device. The switching device is arranged to purchase the dialing device and the microphone speaker to the subscriber line after the external paver operation, for automatic connection of connection between the subscriber's microphone speaker in question and the alarm center with transmission direction towards the alarm center. The alarm center is equipped with a second switching device arranged to switch the transmission direction of the connection to the aforementioned subscriber apparatus after the external paver and to return the transmission direction of the connection to the alarm center after completion of the paver operation.

For example, in a pensioner apartment that enters the alarm system is thus a standard telephone device, e.g. of type "DIALOG", which stares at 3 71028 on a chassis containing electronics and microphone speakers for loudspeaker phone calls. On the chassis panel there is an alarm button which is used if the person is capable of triggering a manual alarm (eg in bed mode). One or more microphone speakers and alarm keys may need to be set up and size.

The call center has a telephone with a secret number. The tele-phone operates on a base whose panel has three knobs with the designations "Start", "Tai" and "Reset".

The course of the now outlined system Sr follows.

Alarms are triggered in the pensioner's apartment. The dialer will then automatically dial the call center's number and continue to call until answers are received. If the number is busy, the rings are repeated at specified intervals until answers are received. With the alarm tone, the base is prepared for loudspeaker calls, ie. tai and listening. A prerequisite for the possibility of listening from the emergency room is that alarm giving has occurred, which is a guarantee of the pensioner's integrity.

When the telephone rings in the call center, the caller on the handset picks up the phone and switches it off, presses the "Start" button and thus can "listen into the home" via the pensioner's microphone speakers. Then press the "Tai" button, introduce themselves, ask who is calling and what has happened. Answers may come when can release button "Tai"; by alternately pressing and releasing the button "Tai" has full control over the call. After the end of the call, you can put on the handset and press the button "Reset", whereby the call center as the pensioner's telephone device is switched off.

If the call center does not receive anything in response to "listening into the home", there is reason to immediately investigate what has happened through the call / visit.

The system can be designed with automatic identification in the emergency room of who the alarm-giving person is, e.g. on a screen or lamp table.

As preceded by the description in the foregoing, the system is arranged for simplex connection, whereby the conditions are good for perceptible tai in both directions, even if the pensioner would be at considerable distance from the telephone, perhaps lying on the floor.

The telephone base panel also has a sensor (microphone) for receiving alarm signals from wall-mounted wireless, mechanical ultrasound transmitters or from a portable seed transmitter. In the latter case, it may take the form of a small plate, which hangs in a chain about the pensioner's neck. In the event of an assault or burglary, a disc print on the plate within a few seconds can give the call center information on what is happening to the tails.

The aforementioned microphone speaker unit may be comprised of a speaker which is switchable to either branch with amplifiers having different transmission directions connected to a subscriber line via a four-wire amplifier circuit.

The switching contact is controlled from the alarm center by the switching device there (the second switching device). The number switching device Sr is connected to the subscriber line and is activated through the switching device in the subscriber's base (the first switching device).

The invention will also be described in connection with the accompanying drawing showing a simplified picking scheme of an alarm system.

A subscriber apparatus 1 is connected over a switching means 2 to a subscriber line 3 which is part of a public telephone network. A wireless transmitter / receiver device comprises a transmitter 4 and a receiver 5. The transmitter 4 is an alarm means carried by the subscriber, and the receiver 5 is arranged in a lower part of the subscriber apparatus 1 and activates, after signal from the transmitter 4, control circuits 6 for connection. of an automatic dialing device 7 and a microphone speaker unit 8 to the subscriber line 3 instead of the subscriber unit 1. Til the control circuits 6 may be connected to additional, permanently arranged alarm means via line 9. The microphone speaker unit 8 comprises a speaker 81, which also acts as a microphone, an amplifier 82 which, via a switching means S3, amplifies the speech current from and to the loudspeaker 81 respectively. For controlling the recorder 83 from the subscriber line 3, there is a tone receiver 84.

71028

The subscriber equipment indicated in the preceding paragraph is served from an alarm center, as on. the drawing is represented by a telephone apparatus 10 with tone signal transmitter 11 for speech control of the connection between the subscriber equipment and the alarm center after the connection is established via the public network 12. The units contained in the alarm system consist of per se well-known details, for which no further description of them is necessary.
