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 AC Power - Main Power Supply

x Notification Appliances

x SLC Circuits

x Relay Outputs

x Voltage Outputs

x Remote Control and Auxiliary Inputs

x Network Wiring (Shielded wire required)

x RS485 Bus Wiring (Shielded wire required)

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.
