Owner's Manual

Sentinel uses four different types of log files to save information about communications, alarms, etc. that can be viewed. All of
the log files can be accessed from the folder where Sentinel is installed and can be viewed with Word or Notepad.
The general information about communications between the Sentinel Central Computer and the field units is logged in the
Activity Log, which is saved as Sentinel.log. It can be accessed from the Sentinel File menu. This file will include the type
of each communication activity (i.e. transmission of time/date, zone data, ET values, etc.) and the time that it occurred. It will
also list communication errors and an indication of whether communication succeeded or failed with each unit.
All communications that Sentinel logs are recorded in this file with the exceptions of Alarms and Run Time Reports, which
have their separate log files.
Sentinel logs the time and alarms received when polling the alarms from the field units, whether polled from the Sentinel
Group Operations menu, Alarms shortcut or from schedule polling in AutoComm. The alarm log is stored in the
calarms.log file located in the folder where Sentinel is installed.
Notice in the sample that when Sentinel polled field unit 105, it found a power failure alarm and displayed the time when it
occurred and when power was restored. Unit 103 also had a power failure but the time was not displayed. Unit 103 is an
older field unit with an earlier firmware version that does not support power failure time log. This is also apparent from the
Sentinel.log listing in which receipt of Special Data from the similar field units revealed that unit 103 has firmware version
1.19 while unit 105 has firmware version 1.31. This emphasizes the importance of receiving Special Data from all units, to
update information regarding field unit firmware version and settings, before setting up the field units.
