Wiring
1. Cabling Keep audio/video wires at least 30cm, 1' away from any AC power lines, fluorescent and
dimmer switches to avoid noise interference.
2. Type of cable Use a parallel cable for connecting door station KA-DAR. Do not use coaxial cable,
individual wires, or shielded cable.
3. Existing cable When existing cable for chime is used, be sure to locate and disconnect the bell
transformer. If unused wires exist in the cable, terminate each extra pair with
a 120W resistor at each end (also in the cable to audio only station).
4. Cable specifications
(1) 0.65mm to 1.2mm (22AWG to 16AWG)
(2) Vinyl jacketed and PE(polyethylene) insulation.
For other types, limit use for distance up to 30m, 100'.
(3) Single core conductor. If stranded, solder the end of conductor.
5. KA-DAR mounting location
(1) KA-DAR door station employs CCD video camera, which is affected by strong light,
such as direct sunlight, porch light or street light which come directly into camera lens.
(2) 30° Angle Box KAW-D
KAW-D surface-mounts on wall (single-gang size). KAW-D can be used to angle the
KA-DAR 30° toward the door. Reversible design allows KA-DAR on either side of door.
