Pre-Construction
In a pre-construction installation, walls and ceilings are open with no drywall installed. This is
desirable and allows the installer greater access than in retro-fit applications. Before actually running
any wire or cable, take the time to look around each room or area of the house and plan your wire
paths for maximum efficiency. Look for routes through uncluttered parts of the stud wall or ceiling that
allow you to group all low-voltage (video, speaker wires, CAT-5, telephone, etc.) wires wherever
possible. It is a good practice to label both ends of all cables and to protect wires by tying a plastic
bag over the ends.
Note: Do not run low-voltage wires closer than 12" from high-voltage wires. If necessary, cross low-
voltage wires at a 90º angle to prevent interference.
Retro-Fit Wiring/ Post Construction
Retro-fit installations are more difficult to complete than pre-construction because walls and ceilings
are intact. Typically wires must be fished into position through walls, floors and ceilings. Holes must
be cut; speakers mounted directly in the ceiling or walls with no rough-in brackets and keypads and
local source wall plates must be mounted in existing drywall.
