WIRING THE T-55 AND T-56 SENSOR
1.
Refer to Figure 2 or 3. Identify the sensor wiring cable. If using 3-conductor cable, this cable
will contain a red, black, and white wire.
2.
Strip back the cable jacket for at least 3 inches. Strip 1/4 in of insulation from each conduc-
tor. Cut the shield and drain wire from the sensor end of the cable.
3.
Connect the sensor cable as follows:
a. Connect the Red wire to the SPT terminal on the controller. Connect the other end of the
Red wire to the left terminal on the sensor's SEN terminal block.
b. Connect the Black wire to the SPTGND terminal on the controller. Connect the other end
of the Black wire to the remaining open terminal on the sensor's SEN terminal block.
c. On the T-56 sensor, connect the remaining wire (White/Clr) to the controller's T-56
terminal. Connect the other end of the White/Clr wire to the rightmost terminal on the
sensor's SET terminal block.
d. On T-56 sensors, install a jumper between the two center terminals (right SEN and left
SET).

must be identical to the CCN Communication Bus wire that is being used for the entire network.
Refer to the CCN Installation and Start-up Manual (808-211) for recommended cable types. Refer
to Table 1 for color code recommendations. For wiring instructions, refer below to the instructions
