  • System and method for minimizing the amount of data being sent on a network for supervised security systems
    Patent number: 8525664
    Abstract: A system and method are disclosed for communicating heartbeat signals representative of the condition of a security system to a monitoring station. A controller is provided that transmits a heartbeat signal to a monitoring station within a given time period and awaits an acknowledgement signal from the monitoring station. If an acknowledgement signal is received within a time interval from the transmission of the heartbeat signal, then the time period is reset and another heartbeat signal is not sent until the next time period. If an acknowledgement signal is not received by the controller within a few seconds of transmitting the heartbeat signal, then another heartbeat signal is sent from the controller to the monitoring station. Heartbeat signals are only transmitted from the controller if an acknowledgement signal is not received from the monitoring station. In this manner, the amount of data sent over a communication link is reduced.
