INSTALLING THE XOi DIGITAL HOME SYSTEM
1. Prewire
The XOi uses Cat-5 cable for keypad control and either two- or four-conductor 16- gauge speaker wire. All the wire is

from each zone to the XOi.
2.The XOi digital home systems require Cat-5, unshielded, twisted pair (UTP), for communication between the keypads/display pads and the main XOi unit. Each end of the wire is terminated with an RJ45 connector.
The XOi system can accommodate 500 total feet of Cat-5 cable for each zone. For the most reliable operation, it is best that no single run of Cat-5 exceeds 250 feet. The correct wiring scheme for the Cat-5 cable is standard EIA/TIA 568A. Properly terminating the Cat-5 cable is crucial for the operation of the system. It is very important to use a good quality crimp tool, and testing each end to end run with Cat- 5 wire tester will insure that your system operate flawlessly, Fig. 1.
