Precautions for wiring

Cable

Use a parallel 2-conductor wiring cable for connection of a video door station.

Select a PE (polyethylene)-insulated PVC jacket cable for low voltage wiring.
- A coaxial cable cannot be used.
- A 2-pair quad-type vinyl sheathed cable cannot be used.

For wiring, separate them for audio/video and door release and keep them more than 10 cm (3-15/16") away from each other.

If existing wiring is used, the device may not operate properly. In that case, it will be necessary to replace the wiring.

When using existing cables, check for short circuit and disconnection before installation.

Disconnection check (6Ω or less)
Connect the ends of one side and make a measure at the other side with a tester.

Short circuit check: ∞Ω (Infinity)

To connect low voltage wires, either crimp them with a crimp sleeve or solder them, and then insulate by covering with insulating tape.

How to connect low voltage wires each other

Crimping with a crimp sleeve

Twist the stranded conductor around the solid conductor at least three times, then crimp them.
Overlap more than half of the width and twist them at least twice.

Soldering

Twist the stranded conductor around the solid conductor at least three times.
Bend the tip and solder it. Make sure no lead wire sticks out.
Overlap more than half of the width and twist them at least twice.

ATTENTION

When crimping with a crimp sleeve, if the tip of the lead wire with connector is soldered, cut off the soldered part before crimping it.

After connecting wires, always check for breaking or insufficient connection. Especially when connecting a wire in the middle of wiring, either crimp it with a crimp sleeve or solder it, and then insulate it by covering with insulating tape. Keep the number of connections as low as possible when wiring. Just twisting wires may cause poor connection, or the surface of the wires may get oxidized and cause a loose connection, leading to malfunctioning or failure.
