Alert Processing
Summary of Alert Sequence Processing.
Assuming that alert modes are NOT set “1=Disabled” or “3=Monitor-only, the following
is a summary of how alerts are processed:
1. Monitored device or condition changes to “alert” condition
2. TrimTrac begins transmitting alert messages
3. Alert message received by server application
4. Server application automatically sends an ACKNOWLEDGE message to
TrimTrac. This will stop the continuous re-transmission of alert messages.
5. Server application notifies service center operator or end-user that an alert
condition has occurred.
6. End-user corrects or resets the device or condition in the field that triggered
the alert in the first place.
7. Once field conditions have been returned to normal, end-user instructs the
server application or service center operator to CLEAR the alert
8. Server application sends a CLEAR message to TrimTrac ProE
9. TrimTrac ProE changes the cleared alerts back to “normal” and resumes its
normal operation.
NOTE: IF A CLEAR MESSAGE IS SENT TO THE TRIMTRAC PROE BEFORE
THE INPUT DEVICE OR CONDITION IS RESET TO ITS “NORMAL”
CONDITION, A NEW ALERT MESSAGE WILL BE INITIATED AND NO
RESPONSE TO THE CLEAR MESSAGE WILL BE SENT BY THE TRIMTRAC
PROE
Priority and Status-Levels
The TrimTrac ProE can be equipped with a Vehicle Adapter or Control Module capable
of monitoring vehicle power and externally wired switches and relay contacts. Each of
these devices must be assigned one of three different priority levels (High, Low,
Medium). Loss of external voltage and tampering (opens, shorts, grounds) with external
wiring are handled as Medium Priority Alerts.
Each alert, regardless of priority, can be in one of five status-levels at any given time:
0=Normal
1=Activated
2=Sent
3=Acknowledged
4=Monitor
Activated
