The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for limiting the amount of data transmitted between a security system and a monitoring station within a heartbeat time interval comprising:
transmitting a heartbeat signal from a controller within a security system to the monitoring station;
waiting a given time period for an acknowledgement signal to be sent from the monitoring station to the controller;
determining whether or not an acknowledgement signal was received by the controller in response to the heartbeat signal; and
if an acknowledgement signal is received by the controller in response to the heartbeat signal, then resetting the heartbeat time interval to transmit a subsequent heartbeat signal from the controller to the monitoring station.
2. The method of claim 1 wherein the heartbeat signal is a first heartbeat signal, the method further comprising:
transmitting a second heartbeat signal from the controller to the monitoring station within the heartbeat time interval if an acknowledgement signal is not received by the controller within the given time period from when the first heartbeat signal was transmitted to the monitoring station;
determining whether or not an acknowledgement signal was received by the controller in response to the second heartbeat signal; and
if an acknowledgement signal is received by the controller in response to the second heartbeat signal, then resetting the heartbeat time interval to transmit a subsequent heartbeat signal from the controller to the monitoring station.
3. The method of claim 2 further comprising:
transmitting a third heartbeat signal from the controller to the monitoring station if an acknowledgement signal is not received by the controller within a given time period from when the second heartbeat signal was transmitted to the monitoring station;
determining whether or not an acknowledgement signal was received by the controller in response to the third heartbeat signal; and
if an acknowledgement signal is received by the controller in response to the third heartbeat signal, then resetting the heartbeat time interval to transmit a subsequent heartbeat signal from the controller to the monitoring station.
4. The method of claim 2 wherein said heartbeat time interval is T and said given time period is represented by \u201cx\u201d seconds, said first heartbeat signal is transmitted from the controller at T\u2212x seconds.
5. The method of claim 2 wherein the time period for waiting for an acknowledgement signal after the first heartbeat signal is transmitted is represented by \u201cy\u201d seconds, said second heartbeat signal is transmitted from the controller at (T\u2212x)+y seconds.
6. The method of claim 2 further comprising transmitting an alarm notification from the controller to the monitoring station if the acknowledgement signal is not received by a given time interval after expiration of the time period.
7. The method of claim 1 wherein the heartbeat signal is a data packet containing information associated with the security system.
8. The method of claim 1 wherein the heartbeat signal is transmitted from the controller to the monitoring station via a GPRS communication link.
9. The method of claim 1 wherein the heartbeat signal is transmitted from the controller to the monitoring station via an internet based communication link
10. The method of claim 1 wherein transmitting the heartbeat signal from the controller includes transmitting the heartbeat signal from a communicator housed within the controller.
11. A method for limiting the amount of data transmitted between a security system and a receiving station within a time period comprising:
transmitting a heartbeat signal from a communicator within a security system to the receiving station within a heartbeat time interval;
waiting for an acknowledgement signal to be sent from the receiving station to the security system;
determining whether or not an acknowledgement signal was received by the security system in response to the heartbeat signal; and
if an acknowledgement signal is received by the security system in response to the heartbeat signal, then resetting the heartbeat time interval to transmit a subsequent heartbeat signal from the communicator to the receiving station.
12. The method of claim 11 wherein the security system includes a plurality of sensors communicating with a controller, said communicator is housed within the controller.

transmitting a heartbeat signal from a controller within a security system to the monitoring station within a heartbeat time interval;
waiting for an acknowledgement signal to be sent from the monitoring station to the controller with the heartbeat time interval;
determining whether or not an acknowledgement signal was received by the controller in response to the heartbeat signal within the heartbeat time interval; and
if an acknowledgement signal is received by the controller in response to the heartbeat signal, then resetting the heartbeat time interval to transmit a subsequent heartbeat signal from the controller to the monitoring station.
