4.2.4.12.6 Event memory<br />
The signalling system has an event memory, which is non-volatile should the mains or bus<br />
power supply fail, in which specific fault messages and all the events in armed security areas<br />
can be recorded.<br />
The following events and fault messages are given time and date stamps and logged in the<br />
event memory...<br />
- "Arming, internal" (internal arming),<br />
- "Arming, external" (external arming),<br />
- "Unarming, internal" (internal unarming),<br />
- "Unarming, external" (external unarming),<br />
- "Alarm" (also subsequent alarms),<br />
- "Detector activated: " (Detector which caused the alarm or subsequent<br />
alarm),<br />
- "Alarm reset" (acknowledgement of an alarm),<br />
- "Sabotage" or "Detector missing: " (cause of the fault),<br />
- "Acknowledgement" (fault acknowledgement),<br />
- "HW: Reset" (return of power supply, programming operation).<br />
i Active detectors are not recorded in the event memory in the "Unarmed" status.<br />
The event memory is opened by pressing the button of the same name on the system page of<br />
the signalling system. A new system page opens, in which all the events are displayed in chronological<br />
order.<br />
The event memory can hold a total of 64 entries (max. 8 display pages of 8 lines). Each event is<br />
given a separate entry. The memory is organised as a "ring memory". When the memory limit<br />
has been reached (= 64 events), a new event will overwrite the oldest event.<br />
The event memory cannot be deleted. The contents are maintained when the main power supply<br />
fails or there is a programming operation.<br />
