ABSTRACT:
This invention provides a security system which remembers an alarm event until either the alarm event is intentionally reset or the condition causing the alarm event is corrected. The security system includes at least one sensor coupled to a hub and at least one hub. A serial chain of hubs is connected to a control unit having a controller. The controller sounding a main alarm when an alarm event is generated by the at least one sensor. After the main alarm is silenced and the security system is disarmed, the controller activates a hub annunciator of a hub connected to one of the sensors having generated an alarm event. When a predetermined period of time from disarming the security system expires, the controller sounds the main alarm if there are any alarm events that occurred during the predetermined period of time that are either not reset or the condition causing the alarm event is not corrected.
