TrimTrac ProE Locator Technical Manual v2.0e

General Alert Handling
Unless the alert mode (as opposed to “alert status”) is configured as “3=Monitor-
only”, alerts are processed in descending order of priority. High Priority Alerts,
for instance, will always take precedence over Medium and Low Priority Alerts
and so on. Other than having their status included in any outgoing data messages,
lesser priority alert alarms are ignored until all higher priority alerts have been
either cleared to “0=Normal” or set “3=Acknowledged”. The status of alerts
configured in the “3=Monitor-only” mode will be included in all STATUS_MSG
and REPORT_POS messages, but activation of any such monitored alerts will not
in and by themselves result in new message transmissions.
When a VAM or Control Module equipped TrimTrac ProE detects activation of a
switch or device, loss of external power or tampering with the external wiring, it
will set the appropriate priority alert status to “1=Activated”, unless the mode of
the alert is set to “3=Monitor-only”, in which case, the alert status will be set
“4=Monitor Activated”. The one exception to this, as more fully described
below, is a Low Priority Alert for which the TrimTrac ProE needs to also detect
motion, in addition to activation of the switch, before the Low Priority Alert
status is set “1=Activated” or “4=Monitor Activated”.
Resetting of the local switch or device will not reset any activated alert unless the
TrimTrac ProE has also received a SET_ALERT_STATE message (See page
147) or if the particular alert mode has been set “3=Monitor-only”.
Furthermore, activated or acknowledged alerts can only be cleared back to
“0=Normal” after the fault or monitored device has been restored to normal AND
the TrimTrac ProE has received the appropriate SET_ALERT_STATE message
or if the particular alert mode has been set “3=Monitor-only”. This will help
guard against an unauthorized person disabling the TrimTrac ProE or the Vehicle
Adapter or Control Module inputs. Alerts whose modes are set to “3=Monitor-
only” will have their status set automatically back to 0=Normal without a
SET_ALERT_STATE message being received; provided, however, that the fault
or activated device has been returned to its “normal” condition.
Whenever an alert changes to “1=Activated” from “0=Normal” (and all higher
priority alerts, if any, are set to either “0=Normal” or “3=Acknowledged” and the
activated alert mode is not otherwise disabled or set “3=Monitor-only”), the
TrimTrac ProE will transition from its current state as follows:
1.
If HPA Status becomes set “1=Activated”, then terminate the current state
and go to STATUS immediately; else
2.
If MPA Status becomes set “1=Activated”, then, if not in TRANSMIT
state, terminate the current state and go to STATUS immediately. If in
TRANSMIT, then go to STATUS upon completion of current
TRANSMIT state (Note: This allows the device to complete sending any
current messages prior to processing the new MPA); else
3.
If LPA Status becomes set “1=Activated”, then, if not in FIX or
TRANSMIT state, terminate the current state and go to STATUS
