    • A method of operating a security system includes activating a security device and transmitting a first status report from the device in response to the activating step. A second status report is transmitted from the device after the first status report has been transmitted. The second status report is indicative of a status of an input of the security device. It is determined whether the first status report indicates a status different than the status indicated by the second status report. A third status report is transmitted from the device after the second status report has been transmitted. The third status report is indicative of the input of the security device being in an alarm condition and/or a trouble condition. Dependent upon whether the first status report indicates a status different than the status indicated by the second status report, an alarm and/or a trouble warning are issued in response to the third status report.
