AVRA
The Automated VR Activation (AVRA) option enables automated DVR ON/OFF control
triggered by an external switch
– portable charger, door switch etc.
If this option is desired, the external switch (provided by others) needs to be wired to one
of the following:
A dedicated VIP Input on the MSU Control Head or DEK.
o
The ‘Automatic VR Activation’ and ‘AVRA Uses VIP on CH’ selection boxes
in the DVRS Hardware Setup menu must be checked.
o
The corresponding VIP I/P must be enabled in the MSU
– refer to the
programming guide provided by Motorola for detailed instructions.
For detailed instructions on VIP wiring, please refer to the MSU installation manuals
available from Motorola.
‘Switch 1 Input’ on the DB15 of the DVR Auxiliary Cable (PN
7W083X06
)
.
o
The ‘Automatic VR Activation’ selection box in the DVRS Hardware Setup
Menu must be checked.
o
The ‘AVRA Uses VIP on CH’ selection box in the DVRS Hardware Setup
menu must be left blank (unchecked).
o
The MSU does not require special programming related to the enabling of
this option.
Status Lights
The Status Lights option provides status identification capabilities. The relay outputs in the
DVRS can be programmed to provide several status indications
– ‘Master Light’, ‘LOC
Mode Light’, ‘SYS Mode Light’ or ‘DVR ON Light’.
The DVR then provides control input to an external switch which in turn toggles an external
light.
The external switch and light are not included with the DVR.
The Light Switch Relay Coil “+” must be wired to +12V DC and the “-“ to the corresponding
Relay Output on the DB15 connector of the DVR Auxiliary cable PN
7W083X06
(500mA
Max).
External Alarm
In applications where the DVR is installed in a fixed 19” rack, the external alarms option
can be enabled and the corresponding relay output wired up to an external logic system
for monit
oring and reporting of ‘low power’ or ‘overt temperature’ combined alarms.
