Wiring
1. Use a parallel cable to connect to KA-DA door station. Do not use any other cable like
coax-cable, individual wires, etc.
2. When existing chime wires are used, be sure to locate and disconnect the bell transformer.
If unused wires exist in the cable, terminate each extra pair with a 120Q resistor at each end of
wires (on audio-only sub station end as well).
3. Cable specifications
1. O.65mm0 to 1.2mm0 (22AWG to 16AWG)
2. Vinyl jacket & PE(polyethylene) insulation.
For other types, limit use for distance up to 30m (100 feet).
3. Single core conductor. If stranded, solder conductor edge.
4. KA-DA mounting location

porch light or street light which comes directly into the lens.
