FIELD WIRING
The field wiring for a KD6 Z-Series Dome is terminated at the interface board. Refer to the
installation guide provided for wiring connections.
1.
Power -
Each KD6 Z-Series Dome requires a separate power source. A 12Vdc or 24Vac
interface board may be provided with the dome.
12Vdc
– A 12Vdc - 15Vdc power supply @ 1.1A is required. A minimum of 12Vdc is required
at each dome for proper operation of the scan. The terminal strip accepts 22-14AWG wire
sizes. The following wire sizes and distances represent one power source for one KD6 Z-
Series Dome.

Control
Data -
One shielded twisted-pair RS-485 cable is required. The data terminal strip
accepts 24-14 AWG wire sizes. The data lines can be home-run wired or daisy-chain wired
from the control output. Home-run wiring is one scan per control output. Daisy-chain
(parallel) wiring is up to 32 scans per data run with the control output at one end of the run or
in the middle of the run.
The data cable shield should be connected together at each dome, but is not connected at
the dome. Connect the cable shield at the control unit. The maximum distance to the last
dome is 4000 feet.
