CAUTION
When installing cables, follow these guidelines:
Avoid excessive lengths of cable at the control and device end. Excess cable should be pulled back to a
duct area where it can be folded and secured. Leave a service loop as directed for specific devices.
Cables should not come into contact with bare metal edges, light ballasts, or magnetic speaker coils. If
ballasts and speaker coils cannot be avoided, cross them perpendicularly.
Cables that are secured with cable-ties should not be tightened to the extent that the cable is
compressed or damaged. The cables should not be crimped, crushed, or severely bent.
When passing cables through tapping plates or metal side walls of the vehicle , insert grommets in the
holes to protect the cable, if possible This may not be feasible in a retrofit situation. If it is not feasible,
make sure that the protective outer CL2 jacket is maintained when passing cable through hole.
When pulling cable through the conduit, do not jerk or over-pull the cables. These actions will stretch
and damage the cable. Attach a pull-line to the cable jacket, not to the connectors.
1) Route cables from each camera location to the DVR location as determined by your customer-
specific system layout. Figure 3 shows an example system layout.
2) If cables must be pulled through vehicle walls with limited access or conduit, attach pull lines to the
cables jackets, and gently pull cables through the appropriate routing paths.
3) After reaching camera locations, leave enough cable for a 6-inch service loop at each location.
4) Pull any excess cable back into the duct area where it can be folded and secured.
