MZC-66 Hardware Installation Instructions Page 17
SYSTEM INSTALLATION
WIRING
Once the system has been defi ned and the contract signed, work can begin. The fi rst part of the system to be installed is the
wiring infrastructure. With all of the fl exibility and options of a MZC-66 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 specifi ed, 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 specifi ed in the system can help down the road,
should the homeowner decide to add rooms to the system at a later date, or increase fl exibility 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 MZC-66 EZ-Pad Terminals. CAT-5 can be used with or without RJ45 connectors. Standard wire can
also be used for retro-fi t installations provided there are at least 5 conductors available. Use of SpeakerCraft RJA-1.1 RJ45
to Wire Pin Adaptors is recommended for EZ-Pad connections. See: IMKP Installation Instructions and MODE 3.1
Installation Instructions for more information regarding connections for those models.
CAT-5 WITH RJ45 CONNECTORS
Requirement - Pull home-runs of CAT-5 from each Keypad location to the System Head-End.
MAXIMUM LENGTH: 1000' (305m) EZ-Pad/IMKP; 500’ (152m) MODE 3.1.
Installation - Terminate the CAT-5 with RJ45 connectors on both ends. Be sure the terminations are identical on both
ends, creating a pass-through (pin to pin) configuration. Connect the CAT-5 cable to EZ-Pads 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 MZC ends, if desired. Be sure RJA-1.1 pin orientation is correct on
both ends prior to powering up the system. Not applicable for IMKP or MODE 3.1.
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) EZ-Pad/IMKP; 500’ (152m) MODE 3.1.
Installation - Strip away approximately 2” (50mm) of the CAT-5 jacket and separate the individual conductors. Strip
approximately
1
⁄4 inch (6mm) of the individual conductors to be used for connection to the EZ-Pads/IMKPs. Twist the
stripped ends so there are no loose strands that can cause shorts. Secure the ends to the EZ-Pad/IMKP terminals.
Maintain proper polarity. For IMKPs, strip approximately 6mm from each conductor and secure to the appropriate
screw-down terminal. For MODE 3.1, secure each lead end (without stripping) to the proper terminal with a punch-
down tool. To terminate MZC ends, strip away approximately 2” (50mm) of the CAT-5 jacket and separate the individual
conductors. Strip approximately
1
⁄4 inch (6mm) of the individual conductors to be used for connection to the removable
screw-down connector. Twist the stripped ends so there are no loose strands that can cause shorts. Secure the ends
to the appropriate removable screw-down connector terminals. Maintain proper polarity. Plug connector into the
appropriate Zone EZ-Pad terminal.
STANDARD WIRE (Recommended for Retro-fit Only)
Requirement - Home-runs of 24-14AWG stranded, non-shielded wire with at least 5 conductors to the System Head-
End.
MAXIMUM LENGTH (24AWG): 1000’ (305m) EZ-Pad/IMKP; 500’ (152m) MODE 3.1.
