2.5 INSTALLING THE IMPACT SENSOR (OPTIONAL)
The Impact Sensor is typically mounted near the DVR and comes with a 7-foot cable that terminates in
the DVR.
CAUTION
Do not install the Impact Sensor until you have tested its functionality on each vehicle. The Impact Sensor
should be mounted on a flat, stable surface and secured to the frame of the vehicle. The mounting surface
must not be subject to vibrations.
1) Using the Impact Sensor as a template, mark the location of the two mounting holes. The Impact
Sensor should be aligned so that it is square with the front and rear of the vehicle. See Figure 16.
2) Drill the mounting holes with an appropriate size drill bit.
3) Mount the Impact Sensor.
