Patent ID: 8339271

Claim:
An intelligent security system comprising: an integrated circuit having a first and a second input and a first and a second output corresponding to the first and second inputs, said integrated circuit also having an alarm output; a processor coupled to the at least two inputs and to the alarm output and coupled to a storage; a computer coupled to said processor via a network connection; said first output coupled to a first remotely monitored device and said second output coupled to a second remotely monitored device; a threshold value stored in said storage and a first measured value for said first remotely monitored device and a second measured value for said second remotely monitored device, wherein if either the first or second measured values exceed the threshold value, a alarm signal is send via the alarm output; said computer transmitting a command signal to said processor to turn one of the first or second inputs off; wherein the remotely monitored device that is in causing the alarm is identified by the cycling on and off of the first and second inputs; at least one end-of-line resistor located in the vicinity of said first remotely monitored device, said at least one end-of-line resistor comprising a circuit coupled to said integrated circuit; said processor applying a current across the circuit; said processor measuring a voltage that develops across the circuit and determining a resistance thereof; said processor storing the circuit resistance in said storage; said processor automatically setting its operational settings in accordance with the circuit resistance such that when said processor reads the circuit resistance the system registers normal operation; wherein when said processor reads a resistance that exceeds a threshold deviation from the circuit resistance, the system registers an alarm.
