Security system with correlated signalling to selected satellite stations
First Claim
1. A security system comprising:
- a plurality of sensors respectively adapted to produce an alarm signal upon occurrence of a predetermined alarm condition at a location monitored by such sensor;
a plurality of encoders respectively connected to said sensors, each encoder being responsive to the alarm signal produced by the sensor connected thereto to encode such alarm signal to identify the corresponding alarm condition and sensor location;
means connected to each of said encoders for transmitting the encoded alarm signals produced thereby over at least one transmission channel;
a plurality of satellite stations respectively adapted to receive correlated signals which uniquely address each of such satellite stations;
a central control station comprising means for receiving and decoding the transmitted encoded alarm signals from said transmission channels;
a computer further comprised in said central control station programmed to correlate each of the decoded alarm signals with information stored in the computer memory relating to each sensor location and alarm condition, and adapted to produce correlated signals which respectively address one or a plurality of particular satellite station to be notified of respective alarm conditions and include the correlated signals to be transmitted to each such satellite station and further adapted to select the number and identities of the satellite stations to be notified, which selection being a function of the nature of the alarm condition and of the location being monitored by said sensor;
and means comprised in said central control station and connected to said computer for transmitting such correlated signals to the satellite stations identified thereby.

Abstract
A security system wherein a plurality of locations are monitored by sensors which transmit alarm signals to a central control station by radio or telephone, each alarm signal being encoded to identify the particular sensor location and alarm condition. The control station comprises a computer which correlates the received alarm signals with information stored in the computer memory to identify which of a plurality of satellite stations are to be notified of a particular alarm condition at a particular monitored location, what correlated information is to be transmitted to such satellite station, and whether to effect such transmission by radio or telephone. The computer actuates a radio or telephone transmitter in the control station to transmit correlated signals to the appropriate satellite stations, and may also actuate a speech synthesizer so that such signals may be transmitted as synthetic speech.
