DVRS Installation & Programming Guide – PART II
The PSU Emergency attempts counter must be programmed to be equal to the DVRS
'Attempts Counter' plus 3.
IMPORTANT
Hot Mic operation is only supported on DVRS Enabled PSUs that are loaded with
firmware R12.00.13 or later. Please check with Motorola for compatibility.

Emergency operation during TG Translation

Emergency operation is affected by TG Translation as follows:
Inbound Emergency Alarm received by the DVRS on TG X will be translated and
repeated locally on all translated TG IDs that are selected on Local PSUs, which are
currently affiliated with the DVRS. The Emergency Alarm is also translated to the ID of
the TG selected on the MSU and forwarded to the System.
Outbond Emergency Alarm received by the MSU on the MSU selected TG (TG Y) will
be translated and repeated to the Local PSUs on all translated TG IDs that are selected
on Local, affiliated with the DVRS PSUs.
Inbound Emergency Call on TG X will be translated by the DVRS to the ID of the TG
selected on the MSU and will be repeated locally on the translated TG.
Outbound Emergency call received on TG Y selected on the MSU will be repeated by
the DVRS to the Local PSUs on TG Y.
If Emergency Revert is programmed in the Local PSU then:
If the revert TG is on the DVRS TG Translation list, then the Emergency will be
translated to the ID of the TG that is selected on the MSU.
Emergency Alarm will be repeated locally on all Translation enabled TG IDs that are
selected on Local, affiliated with the DVRS PSUs.
If the revert TG is not in the DVRS TG Translation list then the emergency will be
proxied and the inbound, outbound and local repeat will be on the new emergency revert
TG.
If the MSU (interfaced to the Master DVR) is placed in Emergency and programmed to
revert in Emergency then a subsequent Local PSU emergency will also be translated
and declared on the MSU's emergency revert TG.

Fireground (FG) Signaling

If Fireground (FG) signaling is enabled in the Local PSUs and on the selected full duplex
DVRS channel, the DVR repeats locally the FG messages received form the Local PSUs
to the FG terminal. If the Local PSUs are programmed for digital voice when transmitting
FG signaling, a digital full duplex DVR channel with FG enabled must be selected.
FG Emergency signaling received from the Local PSU can be either repeated locally,
sent to the System or both (as programmed in the DVR).

Digital Outbound Takeover

When Digital Outbound Takeover is enabled in the DVR, a local PSU call is given higher
priority over an ongoing outbound call as described below.
The DVR stops repeating the outbound call and starts repeating the LPSU call.
The DVR tries to key up the MSU and if channel grant is received, the inbound call is
repeated to the system. Typically the MSU can only get channel grant and key up if the
MSU is receiving on a different TG then the one selected on the LPSU. If the MSU is
