A system and method for storing and monitoring events at security devices

摘要

An alarm or intrusion monitoring system includes a plurality of detectors which communicate with a remote control panel. Each detector includes a memory wherein detected conditions or events are recorded along with a time indicator. Recorded events and respective times of occurrence can be downloaded to the control panel for evaluation. Detected conditions or events can include system conditions, such as faults or detector off-line indicators, as well as various intrusion or environmental-type incidents such as smoke, gas, temperature or fire. The invention assists a user in determining whether a security system provided an alarm in response to a false alarm event (false positive) or judged an alarm event as a false alarm (false negative) when it should have resulted in an actual alarm.
