Event log
The Event log is a record of detector events such as faults, alarms, and function
changes. It is stored inside an operating detector and is updated whenever an
event occurs. The event log is nonvolatile, which means that it is retained when
the detector is turned off. The last 200 detector events may be stored.
An event is defined as:
• A change to any programmed function
• A signal received from an external controller such as the remote software,
APIC, or SenseNET
• A detector output level meeting or exceeding the Pre-Alarm, Aux., Alarm, or
Alarm 2 alarm thresholds
• A start of day or night operation
• Demonstration Mode start
• FastLearn start or stop
• Power on or off
Events can either be viewed on a PC screen or downloaded to disk by running
the Remote application.
When the detector event log is full (200 events have been logged) and a new
event occurs, the oldest event in the log is deleted (first-in, first-out).
To download the event log, connect a PC to the detector serial port and run the
Remote or SenseNET applications.
