5.6.5 PRIVACY SWITCH
A privacy switch can be used to prevent the unit from reporting any location information. To do this,
select a DPST switch for mounting on the vehicle dash, preferably with an illumination lamp indicating it
is on. The more typical switch will light up in the “on” condition and indicate a closed circuit, so unless
you select a Normally Closed (NC) switch, the switch will be lit when in the reporting condition. Turning
the switch and light off will cause it to stop reporting.
One pole should be wired between the ignition wire of the vehicle/vpod and the white wire input of the
device harness. This will normally be wired such that the privacy switch disconnects these two wires
when in the “OFF” position, thus preventing the device from receiving an ignition on event from the
vehicle. An “ON” condition, when the switch is lit, will indicate the device is getting the ignition on
message and is reporting normally.
Additionally, we recommend the use of one digital input to send a message that will appear in
FleetOutlook when privacy mode is on. To do this, splice a wire into the red power wire and connect it
to the second pole of the privacy switch. The other end of that switch pole should be wired to an input
on the device. The switch will open the circuit when the privacy switch is in the “OFF” position. Set an
alert to appear in the breadcrumb detail by creating a Device Condition Change alert in FO. Note that
you need to define the input on the device so that Privacy mode will be active when power is removed
from the input.
