Alarm and emergency call system
First Claim
1. Alarm/emergency call system, comprising:
- a central unit connected to a computer making it possible to;
(a) form function parameters for a plurality of local units, and(b) store the function parameters of the local units in a data base,the function parameters comprising at least one of the following;
(a) the telephone numbers of the recipients of alarm/emergency call messages,(b) the telephone number of at least one monitoring center,(c) an identification number corresponding to the local unit,(d) a predetermined number of alarm and disturbance criteria,(e) the telephone numbers of pager receivers to be called with an (alpha) numeric text,(f) the telephone number of the paging center,(g) the telephone numbers corresponding to the recipients that the user of the local unit can call by pressing a predetermined button of a keypad,(h) the recording of a voice alarm message/call message and a reply message, and(i) the recording of the specific code of a transmitter of associated with the local unit;
a plurality of local units, each;
(a) identical to the central unit,(b) designed so as to be able to be used as a central unit,(c) connected by a telephone line to the central unit,(d) designed so as to send, upon reception of signals, an alarm/emergency call message to at least one recipient over the telephone line,(e) having at least one transmitter associated with each local unit capable of sending signals of a specific code to the associated local unit, and(f) having;
(1) a receiver intended to receive signals sent by the associated transmitter,(2) a keypad,(3) a display unit,(4) a Dual Tone Multifrequency type receiver,(5) a Dual Tone Multifrequency type transmitter,(6) a modem,(7) a voice recorder, and(8) a control unit having;
(i) peripheral microcontroller having memory capable of containing the function parameters and connected by a bus to;
the keypad, the display unit, the Dual Tone Multifrequency type receiver, the Dual Tone Multifrequency type transmitter, the modem, and the voice recorder, and(ii) central microcontroller connected by a bus to;
the peripheral microcontroller, the receiver, the modem, and the display unit,(9) a loudspeaker amplifier, and(10) a telephone interface connected to;
(i) a loudspeaker amplifier,(ii) the modem,(iii) the receiver,(iv) the Dual Tone Multifrequency type transmitter, and(v) the voice recorder; and

Abstract
The alarm and emergency call system having a plurality of local units installed at the users and connected by a telephone line to a central unit having the same design. Each local unit is in radio connection with alarm transmitters and has a control member with an electronic circuit contained in a case, a keypad, and a display unit. Following an alarm signal sent by one of the transmitters, the local unit in question calls different telephone destinations and/or pagers according to a determined cycle. The different function parameters of each local unit are stored in its control member. These function parameters can be entered, adapted or modified remotely from the central unit according to a remote management procedure.
