Remote Mode change of DVRS by FNE / Dispatcher
Dispatcher can send a call alert (page) to a specific MSU ID, which in turn causes DVR
mode change in the following order: OFF-SYS-LOC-OFF.
The MSU can be programmed to support one of the following configurations:
•
Call Alert / Remote Activation Disabled
– the MSU does not respond to any Call
Alert requests
•
Call Alert Enabled
– the MSU responds to Call Alerts addressed to its ID and
does NOT initiate DVRS mode change
•
Remote Activation Enabled
– the MSU will acknowledge Call Alerts addressed
to its ID and will initiate DVR mode change provided the source ID of the Call Alert
is programmed in the “DVR Remote Activation IDs” table.
•
When MSU is involved in any one of MSU features (emergency call, private call,
status, etc.) MSU will not accept the call alert from FNE.
“DVRS Remote Activation via Call Alert” feature is blocked by the MSU.
If “Generate Status on DVR Mode Change” is enabled for a given DVRS Profile (in the
APX MSU) , the MSU will send back a mode change status to indicate the current DVRS
mode (OFF, SYSTEM, LOCAL). Only the dispatcher console can interpret those status
messages:
DVR MODE
STATUS VALUE
OFF
1
LOCAL
2
SYSTEM
3
Dispatcher can’t force a non-primary DVR to become a primary and can’t activate a DVR
when a ‘VR Disabled’ mode is selected on the control head.
