Telecommunity alarm system with a plurality of security surveillance modems
First Claim
1. A telecommunity alarm system including a plurality of security surveillance modems which can be connected to a telecommunications network to form a group of predetermined size, each security surveillance modem comprising:
- at least one input to which a detector for sensing an alarm status can be connected;
a first memory capable of being programmed with telephone numbers of other security surveillance modems of the group;
a second memory containing an identification message identifying the security surveillance modem; and
a programmable control unit connected to the first memory and second memory and to a telephone system, the programmable control unit for automatically dialing at least one of the telephone numbers entered in the first memory in response to an alarm signal supplied by the detector and for sending the identification message stored in the second memory to another security surveillance modem of the group,the programmable control unit connected to an alarm signal device and to a display for displaying a received identification message.

Abstract
A telecommunity alarm system having a plurality of security surveillance modems that can be connected to a telecommunication network via an analog or digital subscriber terminal port, the security surveillance modems forming a group of a predetermined size. The security surveillance modems each have a first memory for storing telephone numbers of the other modems in the group, a second memory for identifying the particular modem and a programmable control unit. The modems are designed to dial automatically, in the event of an alarm, the other security surveillance modems belonging to the group and signal the alarm status.
