Wiring Specifications

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:
High voltage
SLC loops
POTS reporting input/output Phone line circuits, TELCO
Notification circuits
SBUS
Relay circuits
• 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.
