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
1
Twist the stranded conductor around the solid
conductor at least three times, then crimp them.
2
Overlap more than half of the width and twist them
at least twice.
Soldering
1
Twist the stranded conductor around the solid
conductor at least three times.
2
Bend the tip and solder it. Make sure no lead wire
sticks out.
3
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.
