Install Backup Batteries
Before proceeding with system setup, install the backup batteries in the module. Open the two battery
compartment covers on the top of the module.
Locate the red (positive) and black (negative) wires with female spade connectors under each door.
Move the wires out of the way and place the batteries in the holders and connect the spade terminals to
the batteries as shown below.
Connect the red leads to the positive terminal of each battery and the black leads to the negative ter-
minal of each battery.

The Tek-CARE120 Data Bus
The Tek-CARE120 data bus is a two-wire serial communications bus. There are four ports on the front of
the module, each capable of driving up to 1,000 feet of data bus and up to 16 LI122-Series room con-
trollers.
There are four 8P8C jacks on the front of the module. The two on the right are for NC415AV Master Sta-
tions, and two on the left for Tek-CARE Network connectivity. Each module supports up to six master
stations, three per port.
To begin installing the NC120 CE Module, mount the module either on a server rack or on a shelf. Plug
in the supplied AC power cord, and turn the unit on. You are now ready to begin connecting field wir-
ing to the module.
