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.
Pre-Wiring
D5XH to D5KP Keypads
The D5XH and all associated components are wired using Cat-5 terminated to the T-568A Wiring
Standard (Figure 2-2). When pre-wiring, run lengths of Cat-5 from the pre-determined equipment
location (the “head-end”) to each Keypad location. The Cat-5 routes all audio, power, IR and status
information needed for full system operation.
Note: For maximum performance over long runs (more than 150 ft) run an additional 16AWG 2-
conductor wire for external power.
