Section 2 – General Wiring Specifications
Care should be taken when wiring the system to avoid situations that would contribute to inducing
electrical noise from one wire to another. Induced noise can interfere with telephone communications or
cause erratic system operation. Follow these general guidelines to plan your system wiring prior to
installation.
x
Route high and low voltage wiring separately. Maintain a minimum 2” separation between high
and low voltage wiring throughout the building.
x
Route control panel wiring around the perimeter of the control panel enclosure. A minimum .25”
separation is required between high and low voltage wiring.
x
Identify which group each wire or cable is associated with from the list below. Isolate each
group’s wiring as much as possible. Avoid running a single multi-conductor cable for multiple
groups of conductors.

x
Keep wiring from different groups separated as much as possible. If you must share the same
conduit with different conductor groups consider using shielded cable.
x
If shielded cable is used terminate the shield to the earth ground terminal block in the main
control panel and leave open at field side of cable. Do not ground at both ends of cable.
