Installing the VISTA Vehicle Kit
Connecting the External Inputs Cable
Warning!
Only connect cables when the full installation workflow on
instructs you to. Connecting cables out of sequence can damage components.
The external inputs cable connects the Smart
Power Switch sense wires to various external
device inputs, for example, ignition, siren, and
door switch.
The sense wires in the external inputs cable
monitor the external device inputs for voltage
(8-12 volts) and no voltage (0 volts). When an
external input wire senses voltage from an
external device, the Smart Power Switch
informs VISTA WiFi or VISTA XLT so it can
start recording an event, if configured to do so
in the agency's Evidence Library software.
The presence of voltage on the sense wire also signals to the system to add the external device
activation information to the metadata file.
Connect each sense wire in the external inputs cable to the corresponding external device input
wire:
Tip:
Where possible, use butt splices when you connect the wires to ensure good
connection and consistent voltage.
l
Ignition (white)
: The white wire senses whether the ignition is on or off
Connect the white wire to a feed (switched ignition accessory wire) that provides positive 12
volts when the vehicle ignition is ON and 0 volts when the vehicle ignition is OFF. A fuse link
with a 1-amp fuse is provided to connect the ignition feed with the ignition sense wire from the
external inputs cable.
l
Emergency lights (blue with white stripe)
: The blue wire with the white stripe senses
whether the emergency lights have been activated
Connect the blue wire with the white stripe to a positive 12-volt switched power source that
provides voltage when the emergency lights are activated.
Note:
Some manufacturers of older-type light bars use negative 12 volt
or ground triggers. In those cases, you may need to incorporate an
additional relay into the wiring scheme to provide positive 12 volt power
to the external input wire.
