Description
wwir1810s * 5345FE 6.92
18 AWG, 10-conductor stranded copper
wire with overall shield and common
ground (PVC Insulation)
wwir1804s * 9418 6.92
18 AWG, 4-conductor stranded copper wire
with overall shield and common ground
(PVC Insulation)
wwir1802s 8760 6.92
18 AWG, 2-conductor stranded copper wire
with overall shield and common ground
(PVC Insulation)
wwir2210s 9946 17.5
22 AWG, 10-conductor stranded copper
wire with overall shield and common
ground (PVC Insulation)
* Denotes standard recommended wire.
Never use wire smaller than 22 AWG for installing LEF or NEM intercoms. We recommend
that 18 AWG be used in most installations for best results. Do not exceed 1600 feet in
linear distance when using 18 AWG or 600 feet in linear distance using 22 AWG.

** 1802S can be used for power by many types of cameras.
*** 2450 or 2210 can be used for interior video signal using Baluns (see Application Note).
Baluns are video signal
converters that allow
twisted pair cable to be used to
carry video signals up to 1200
feet. Two baluns are required
for each camera connection
(one at the camera end and
one at the DVR end). This is an
efcient way to run video signal
on sites with a lot of cameras.
Contact a PTI Security Systems
Sales Representative for more
information on Baluns.
When retrotting an
existing facility, we do
NOT recommend that you use the
existing wiring. New wire should
be pulled and all new connections
made. Old wiring is often the
source of many problems in a
system and the initial investment
to install new wire will make the
overall retrot experience much
better as there is less likely to be
problems in the new wiring if it is
installed correctly.
