2. System Design Overview/Applications
Planning
Before installing the D5SH4, it is essential to have a detailed and accurate system design. The first
step to a good design is to map the system. It is advisable to mark up a copy of the house floor plan
with speaker, keypad and equipment locations, etc. Make sure that all locations are decided upon
before pre-wiring so that all necessary wiring and installation hardware is in place.
It is essential that ALL system components are accounted for prior to the pre-wire stage. After
establishing design goals, make a detailed list of all components. Include source equipment, keypad,
expansion hubs, local source wall plates, IR emitters, etc.
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
D5SH4 Digital Audio Distribution Hub to D5KP Amplifier Keypad
The D5SH4 and all associated components are wired using CAT-5 terminated to the T-568A Wiring
Standard (Figure 2.1). When pre-wiring, run lengths of CAT-5 from the pre-determined D5SH4 Digital
Distribution Hub location (the “head-end”) to each Amplifier Keypad location. The CAT-5 routes all
audio, power, IR and status information needed for full system operation. Use a 110 Punch-down tool
to connect the CAT-5 wiring to the Digital Audio Distribution Hub.
Note: For maximum performance over long runs (more than 150 ft) run an additional 16AWG 2-
conductor wire for external power.
