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 page 9)

* 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 is free from building material obstruction like concrete.

* 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 your AC AM Radio. 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 powerlines for communication. Interference affects 1 maybe 2 channels on the whole spectrum of the bandwidth. To meet the challenges, multichannel intercoms were created as a solution for users to pick a clean channel for the monitoring 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 North America.

* 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.
