SYSTEM INSTALLATION
WIRING
Once the system has been defined and the contract signed, work can begin. The first part of the system to be installed is the
wiring infrastructure. With all of the flexibility and options of a MZC-88 System, maintaining clear, accurate documentation of
the location (the house) and the system will help in managing a smooth installation. Always be sure to pull and test the wires
needed for the system as specified, and always consider pulling extra wire for fall-back in the event something gets damaged
during drywall installation. Beyond that, pulling additional wire to rooms not specified in the system can help down the road,
should the homeowner decide to add rooms to the system at a later date, or increase flexibility within already active rooms.
There are certain types of wire that are default requirements and there are others that are used for the system optional fea-
tures.
KEYPADS
SpeakerCraft EZ-Pads have seven-position spring clip terminals for wire connections. Five of these terminals are used for
connection to the KCM-1.0 EZ-CONNECT KEYPAD MODULE. CAT-5 can be used with or without RJ45 connectors. Stan-
dard wire can also be used for retro-fit installations provided there are at least 5 conductors available. Use of SpeakerCraft
RJA-1.1 RJ45 to Wire Pin Adaptors is recommended for both EZ Pad and KCM-1.0 CAT-5 connections.
CAT-5 WITH RJ45 CONNECTORS
Requirement - Pull home-runs of CAT-5 from each EZ-Pad location to the System Head-End.
MAXIMUM LENGTH: 1000' (305m).
Installation - Terminate the CAT-5 with RJ45 connectors on both ends. Be sure the terminations are identical on both
ends, creating a pass-through configuration. Connect the CAT-5 cable to the keypads using SpeakerCraft RJA-1.1 RJ45-
TO-WIRE PIN ADAPTERS. Insert the RJA-1.1 pins into the keypad’s EZ-Connect Terminals and snap the levers in place.
RJA1.1’s can be used at both the keypad and KCM-1.0 ends, if desired. Be sure RJA1.1 pin orientation is correct on both
ends prior to powering up the system.
CAT-5 WITHOUT RJ45 CONNECTORS
Requirement - Pull home-runs of CAT-5 from each EZ-Pad location to the System Head-End.
MAXIMUM LENGTH: 1000' (305m).
Installation - Strip away approximately 2” of the CAT-5 jacket and separate the individual conductors. Strip approximately
1
⁄4 inch on both ends of the individual conductors to be used for connection to the KCM-1.0. Twist the stripped ends so
there are no loose strands that can cause shorts. Secure the ends to the EZ-Pad and KCM-1.0 terminals. Maintain proper
polarity. The 3 unused leads of the CAT-5 cable can be connected in parallel, one, with each of the +12V, GND and IR/IO
leads, for better IR performance when running long lengths of cable .
STANDARD WIRE
Requirement - Pull home-runs of 28-14AWG stranded, non-sheilded wire with at least 5 conductors to the System
Head-End.
MAXIMUM LENGTH: 1000’ (305m).
Installation - Strip away approximately 2” of the wire jacket and separate the individual conductors. Strip approximately
1
⁄4 inch on both ends of the individual conductors to be used for connection to the EZ-Pads and KCM-1.0. Twist the
stripped ends so there are no loose strands that can cause shorts. Secure the ends to the EZ-Pad and KCM-1.0 terminals.
Maintain proper polarity. Unused leads can be connected in parallel, one, with each of the +12V, GND and IR/IO leads,
for better IR performance when using lighter gauge wire on long runs.
