Induced noise (transfer of electrical energy from one wire to another) can interfere with 
telephone communication or cause false alarms. To avoid induced noise, follow these 
guidelines:

•

Isolate input wiring from high current output and power wiring. Do not pull one multi-
conductor cable for the entire panel. Instead, separate the wiring as follows:

•

Do not pull wires from different groups through the same conduit. If you must run them 
together, do so for as short a distance as possible or use shielded cable. Connect the shield 
to earth ground at the panel. You must route high and low voltages separately.

•

Route the wiring around the inside perimeter of the cabinet. It should not cross the circuit 
board where it could induce noise into the sensitive microelectronics or pick up unwanted 
RF noise from the high speed circuits. See Figure 3-1 for an example.

•

High frequency noise, such as that produced by the inductive reactance of a speaker or 
bell, can also be reduced by running the wire through ferrite shield beads or by wrapping it 
around a ferrite toroid.
