3.5 Wiring Specifications
The induced noise (transfer of electrical energy from one wire to another wire) can interfere with the telephone communication
or cause false alarms. To avoid induced noise, follow these guidelines:
•
Isolate the input wiring from the high current output and the power wiring. Do not pull one multi-conductor cable for the
entire panel. Instead, separate the wiring as follows:
•
Do not pull the wires from the different groups through the same conduit. If you must run them together, do so for as short
a distance as possible, or use the shielded cable. Connect the shield to the earth ground at the panel. You must route the
high and the 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.
