1.3 - Alarm Extender
The Alarm Extender is used to attach 8 custom sensors, supply 12v power output and
ground, relay sensor output, and as a secondary speed sensor.
The eight custom sensors can e configured to use a “normally open” or “normally
closed” circuit. This means that the sensor can e triggered either when positive voltage
is applied or when zero voltage is applied (ground). These sensors are commonly used
to tie into existing vehicle electronics such as rake lights, head lights, seat elts, turn
signals, hazard indicators, reverse gear, spot lights, roof mounted light ars, manual
emergency uttons, doors, or any other actuated device in the vehicle. These can each
e custom la eled in the DVR’s sensor configuration menu.
The two sensor relay output supply a positive 12v 250 mA signal when a sensor has een
activated. This can e used to actuate other devices in the vehicle, sounds alarms, or
flash secondary indicators on the dash.
The secondary speed sensor is used when the vehicle is equipped with a specific com-
pati le speed sensor usually coming off of the transmission or ECU. This can e used
instead of GPS to determine vehicle speed y the DVR.
The power output can e used to power cameras, routers, switches, or other mo ile ac-
cessories.
NOTE DO NOT EXCEED 2.5 AMP DRAW THROUGH SENSOR PANEL. DO NOT
POWER MONITORS VIA THE SENSOR BLOCK.
