2.0 System Design Overview/Applications
Notes:
A recommended electrical back box is always required for all installation of this
product (see specifications).
This keypad is specifically designed to work with the MRC88m and
MRAUDIO8x8m
(Firmware ver. 2.03 or later)
. It is NOT designed to work with
MRC88, MRAUDIO8x8, MRC44, MRAUDIO4x4, or BXAUDIO4x4.
This keypad is compatible with Zone Linking. However, the Dynamic Zone
Linking function can only be initiated with an MRKP2, MRKP2E, or an LCD
Touch panels. Static Zone Linking can always be configured through Universal
Dragon™.
Planning
Before installing the MRKP1, 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 electrical back- brackets and
keypads and local source wall plates must be mounted in existing drywall.

Pre-Wiring
CAT-5 Wiring between MRC88m and MRKP1
The MRC88m and all associated components are wired using CAT-5
terminated to the T568A or T568B Wiring Standard (Figure 2.1). When pre-
wiring the system, run lengths of CAT-5 from the pre-determined MRC88m
location to each Keypad or Touch Panel location. The CAT-5 cable routes all
Power, Control, Communication, and IR information needed for full system
operation.
Important:
While there are two wiring standards, it is very important to be
consistent to one configuration throughout the entire system. Otherwise, the
system will not operate.
Note:
Speaker wiring will need to be separately routed from the MRC88m to
each zone.
