for your client’s records. Letter and number cable iden-

8.4.7 Wiring Chart
Every AC installation comes with at least a rudimentary
circuit map attached to the door of the service entrance.
Your SMC serves the same purpose as a location for a
wiring identification chart for your low-voltage system.
This chart (see page 8-12) should include pathways for:
• Category 5 or 5e cables for telephone and voice/
data distribution
• Coax cable for video distribution
• 16/2 or 14/2 Type CL-II stranded copper wire for
speaker wiring
• Other wiring or cable (for example, fiber)
Installer’s Tip: For an even more foolproof identifica-
tion, duplicate labels can be placed on the inside of
the wallplate.
A wiring chart should refer to the rooms or sections of
the house where the end-point devices are located in
such a way that anyone can identify those areas.
Simply to state “Bedroom #1” can be misleading to a
future homeowner or technician. The chart should
employ more accurate directions, such as “2nd floor
NW bedroom,” to avoid confusion. An example wiring
chart is shown on page 8-12.
8.5 Pre-Wire for Individual
Devices
Each end-point device calls for its own wiring require-
ments such as cable type and location. The following
summarizes these requirements:
• Run Category 5 or 5e cable to every data and phone
wallplate
• Run Category 5 or 5e cable to every IR target and
emitter location and leave instructions for drywall
installers that Category 5 or 5e cable of IR Targets (in
ceiling or walls) should protrude through drywall with-
out an electrical box or mud ring.
• Run two RG-6 quad shield coax cables to every
TV/video outlet
• Run additional RG-6 quad shield and Category 5 or
5e cable to every camera location, checking mount-
ing heights
• Run additional RG-6 quad shield and Category 5 or
5e cable to any location where multi-room
audio/video is planned
• Run two cables of minimum 16/2 AWG speaker wire
and a Category 5 or 5e cable from each volume con-
trol location to the SMC. Run one cable of minimum
16/2 AWG from each volume control to each speaker
in the same room. A simple method for assisting dry-
wall installers to accurately locate speaker wiring
(without an electrical box or mud ring) is to attach
cardboard to the appropriate wall stud or ceiling joist.
Then, drill a hole in the cardboard at the desired loca-
tion, just large enough to pull the speaker wire
through.
Note: You may have a higher cable count than needed
for the number of connection points in the SMC. This
approach enables future expansion and can save much
time and expense in the long run.
Installer’s Tip: An alternative to individual Category
5/5e and coaxial cables is CEBus®, which stands for
Consumer Electronics Bus. This is a communications
standard for in home networks developed by the
Electronics Industry Association (EIA) and the
Consumer Electronics Manufacturers Association.
CEBus houses twisted pair (TP) cable, coax cable,
RF and infrared all under a single jacket. It’s expen-
sive and its major advantage is centralizing multiple
media in a single cable.
8.6 Volume Control and
Speakers Location
Considerations
There is a certain science to the placement and instal-
lation of speakers for multi-room stereo systems.
Generally, speakers should:
1. Face the typical sitting location of the listeners
2. Be located on the long wall of a room for accurate
stereo imaging.
Once you have selected the best wall for speaker
mounting, the rule-of-thumb is to mentally divide the
wall into three equal vertical sections. The imaginary
lines where any two sections meet are the best loca-
tions for the speakers (after you’ve taken into account
furnishings, fireplaces, windows, and light fixtures).
This method places the speakers roughly equidistant
from the room corners (called boundaries) and from
each other.
