Fig. 14 — Communication Bus Wiring to Zone Controller

Before wiring the CCN connection, refer to the Connect to the CCN Communication Bus section on page 26, for commu- nication bus wiring and cable selection. The cable selected must be identical to the CCN communication bus wire used for the entire network.

The other end of the communication bus cable must be con- nected to the remainder of the CCN communication bus. If the cable is installed as a T-tap into the bus, the cable length cannot exceed 100 ft. Wire the CCN service jack of the sensor in a daisy chain arrangement with other equipment. Refer to the Connect to the CCN Communication Bus section, page 26, for more details.
