Knowledge Base
* The term "wireless" is a branding employed by those BIG retailers from
over 20 years ago. The official product name is Power-line Intercom
System.
* If you cannot insert the 3 pronged plug to your outlet that means the
wiring at your house is not meeting the System Requirement. Do not
attempt to alter the power cord or the plug. Use the 3 prong to 2 prong
adapter and set up the system like a Traditional 2 pronged system (see
Solution 1: Electrical Wirings on page9)
* There are no fixed rules on how to utilize the channels. It can be used
as all paging, monitoring or unit to unit per designated channel
communicating. Combinations can be 2 sets of 3 channel twin sets &
makes it six units, or one twin units 4 channel sets. Some users would
believe the number of channels = to the number of units. This is not
exactly true.
* Power-line Intercom Systems communicate via the power-lines of the
house; therefore, it has further distance than a Radio wave Frequency
intercom, which isfree from buildingmaterial obstruction likeconcrete.
* Power-line Intercom Systems use the AC power line as the medium. It
is subject to any interference already existed in the power-lines, such
as yourAC AMRadio. There is NO defectiveness with the system.
* Static & noise interferences were fed into the power-lines by bad
appliances with characteristics of hums, buzz, sizzle or roar
punctuated by pops & crackles. About 8 to 10% of the households are
affected by these Interferences. Power-line intercoms rely on power-
lines for communication. Interference affects 1 maybe 2 channels on
the whole spectrum of the bandwidth. To meet the challenges, multi-
channel intercoms were created as a solution for users to pick a clean
channel for themonitoring purpose.
* Dual Phase AC wiring is defined as one 220 volts service drop from the
utility company coming in to the building. The 220 volts are divided into
two phases of 110 volts each with half the building wired on one phase
and half on the other to even out the load. In an optimal scenario, the
upper outlet is phase one & the lower outlet is phase two. Dual Phase
wiring affects all buildings in NorthAmerica.
* Power meter: In general utilities supply & billing, one household should
have only one power-meter. Multiple power meter situations is common
in some commercial units, when the tenant rents 2 units & joins them as
one. In a residential situation, multiple power meters are possible with
duplex, shops & multi-units rental businesses. All power-line Intercoms
transmit & receive within one power meter. This is a major security
feature.

READ THIS BEFORE OPERATING YOUR UNIT
Units shipped to North America are designed for operation on
120 VAC only.
Safety precaution withuse of apolarized ACplug.
Improper extension cords are a major cause of fatalities. The
fact that the equipment operates satisfactorily does not imply
that the power source is grounded and that the installation is
completely safe.
For your safety, if in any doubt about the effective grounding of
the power source,consult a qualifiedelectrician.
The power supply cord should be routed so that they are not
likely to be walked on or pinched by items placed upon or
against it.
Never take hold of the plug or cord if your hand is wet, always
grasp the plugbody when connectingor disconnecting it.
To reduce the risk of fire and electric shock, do not expose this
product to water, rain, splashing,dripping or moisture.
Do not use this product near water - for example bathtub, sink
etc.
When the unit is not used for a period, turn the power off and
unplug it fromthe outlet.
Do not attempt to modify this product in any way without written
authorization from Intercom Central. Unauthorized modification
could void theuser's authority tooperate this product
To prevent electric shock, match the wide blade of the plug to
the wide slot ONLY, fully insert.
To ensure safe operation, the three-pin plug supplied must be
inserted only into a standard three-pin outlet which is
effectively grounded throughout the building's wiring.
Extension cords used with the equipment must be three-core,
three prongs and be correctly wired. If the plug should fail to fit
into the socket/outlet, contact a licensed electrician to replace
the old andobsolete outlet. DoNot TAMPER with the plug.

Solution 2: PowerMeter
This is common in business offices when one or more units were
combined as one business. For the ease of management, the property
owner usually employed the "one meter per unit" policy. For the tenants,
they will endup with morethan one meter.
The solution to this problem is to run an electrical wire from one meter to
the other meter, or usethe system in a different location

Interference and Noise
(Recap of thedisclosure from the "Knowledge Base" section of the
on-line sales page)
The Power-line intercomsystem communicates by using the power-line in
the building. It is subject to any interference already existed in the power-
line, just likeyour AC AM radio.
Static, noises and interferences will feedinto power-lines bybad
appliances with characteristicsof hums, buzz,sizzle or roarpunctuated
by pops &crackles. About 8 to10% of the households are affected by
Interference. Interference usuallyaffects 1 ormaybe 2 channelson the
whole spectrum ofthe bandwidth. To meet thechallenges, multi-channel
intercom was createdas a solutionfor users to pick a cleanchannel for
communication. The mostcommon appliances that create interference
are microwave ovens,hair dryers, motors and non compatible electrical
component combinations, likeCFL non-compliance timers.
The only wayto eliminate thenoise is to locate the source.The system is
NOT Defective.

Provide the wiringin the premiseis properly groundedat the third leg of
the socket & you have only ONE Power meter, the system will works off
the existing electrical wire of the building. There is NO radio wave in
operating the system. Therefore you are no longer limited by building
materials like "thick Walls". There is no need for socket matching (same
line) like theTRADITIONAL 2 pronged system does.
You can use all the wiring at the house vs. just half of the house with
the traditional 2 wire intercoms. Justsimple plug anduse.

Troubleshooting a Bad Unit
For any communication problem ranging from "right out of the box" or
having using the system for a while and changing locations, most of the
problem are caused by electrical wiring problem in the house. However
occasionally, a bad unit could also be the culprit. To isolate the problem,
please follow thefollowing steps.
Solutions:
Solution 1: ElectricalWiring
Although the electrical wiring failed to meet the system requirements, you
can resolve the issue by setting up the system like a Traditional 2 wire
Intercoms by followingthese simple steps.
1) Set all unitsto the SAMEchannel. For example,channel 2
2) Plug the 1stunit to oneof the outlets.
3) Adjust the unit to mid-volume. Feed a radio to the intercom as a sound
source.
4) Leave the 1stunit at its location. Never relocatethe 1st unit.
5) Press the "lock" button on the 1st unit. This will activate the unit to
constant on.
6) Takethe 2nd unitto another location.Make sure itis also on channel 2.
Adjust the unit to mid volume. If you can hear the radio from the 1st
unit, you havefound the right outlet.
7) If you cannot hear the radio from the 1st unit, try plugging the 2nd unit
to other outlets from within the same location, e.g. the upper or lower
socket.
8) Repeat the same procedures for allthe remaining units.
1. Plug all units into one SINGLE POWER STRIP. Set all units to the
same channel, e.g. channel 3. Adjust the volume for all units at mid-
level to avoidfeedback. Trycommunicating all unitswith each other
2. If anyone one of units that is not communicating while on the SINGLE
POWER STRIP, that unit IS defective. Thatunit must bereplaced.
3. If all units are communicating. The system is NOT DEFECTIVE.
4. You can RESOLVE the above issue by following the Installation Steps
in Solutions #1 below. If you have performed the Installation Steps
and the system is communicating while on a power strip, but not at the
outlets throughout the house, please also check if you would have
more than one power meter. If you do, you can resolve the problem
with Solution #2.
** The test mustbe performed ona Single Power strip.
*** Never perform the test on any in-wall electrical outlets. Your test will
be affected bythe dual phasewiring & therefore inconclusive.
** The Power strip is ONLY for TESTING purpose. NOT meant for
operations.

Don't s
Do not operate the system in a shared power meter environment.
Should there are more than one household sharing the power meter,
every households will have the same access to the conversation. There
will be neither privacy nor security if the system is operated in a shared
power meter environment.
No surge protector. It will degrade the system's performance
significantly.
Do not operate the system in an outdoor environment. This system is NOT
designed for outdooroperation.
Do not use 2 prongs extension cord. It will lose connections to the other
half of thehouse.
Do not tamper with this 3 prong plug. Each blade of the plug has a
special purpose for seamless communication. If your socket is not fit with
the plug, you are not meeting the system requirement (see System
Requirement on thesales page). You should
When Thing GoneWrong - Troubleshooting & Solutions:
There are onlyTHREE causes for communicationproblems.
1) Electrical Wirings. ** Power-lineIntercoms rely onelectrical wirings
to communicate witheach other.
1) Set up the system as a Traditional 2 prong system (refer to solution #1
on page 9)
2) Contact a qualify electrician to upgrade the electric wire system in the
building.
Some houses were built before ground
pronged is required.
These old wirings were upgraded; but not
throughout the wholebuilding.
The ground prong in the socket is not
grounded (connected)
All these can easily be identified
(troubleshoot) by using this 3-wire tester.
You can get it from Amazon, Home Depot &
OSH for a few dollars. Please keep the tester
should any of your home appliances fail in the
future. (To resolve wiring problems please
refer to Solution#1)
2) Power Meter: There is morethan one meterin the service area.
(Solution #2).
3) Bad Units: one of theunits is bad.

Provided that thesystem requirements aremet, setupand installation are
just simple plug and play. Simply plug the intercoms into any electrical
outlets and enjoy communications throughout the whole premises.
This power line communication device uses the electrical wiring from
inside the building. It DOES NOT require radio waves as the
communication is no longer limited to building materials, walls, etc. The
system communicates whereverthe electrical wiregoes.

What would happenif my wirings are not GROUNDED???
Can I stilluse this system???
Yes, you can. You do need to set up the Advance 3 Prong as a Traditional 2
pronged system. Please refer to the Troubleshooting and Solution
section on page 9. Without the ground wire, the dual phases of the
electric wires can no longer be bridged. You can only use one of the two
phases in yourelectrical wire.
