'(/7$ 23 recalls in its electronic memory the most recent 1,500 to 2,000
events, faults, pre-alarms, fire alarms, operations on the panel’s keyboard, etc.
Further control panel activity will also be saved, but it will overwrite the oldest
messages in the memory. In other words, the system will always ‘remember’
the most recent 1,500-2,000 events.
All these events — the system log or history of events — are stored
chronologically, allowing the possibility of maintaining statistics concerning
alarm situations. The data can also be used to take decisions in order to prevent
false alarms in critical environments.
The log provides information about:
• Type of event, (alarm, pre-alarm, fault, function, user operations, etc.)
• Loop- and/or address number, analogue values, etc.
• Time & date of the occurrence.
The system log of events can be presented on the following equipment:
• 2QWKHV\VWHPSULQWHU
(connected directly to the panel)
• 2QWKHRSHUDWLQJSDQHOGLVSOD\
(scrolling of events on the display)
