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.
* Simple power-line communication. NO Radio Wave. Therefore NO transmission nor receiving process.
* Do not use any 3 pronged to 2 pronged adapter. do not use this ystem on ANY 2 pronged AC outlet. It will defeat the dual phase wiring bridging feature of the system. In a word, any of those adapter will downgrade the 3 pronged system to a 2 pronged system. You will be facing the Dual Phase wiring problem just like a regular 2 pronged system.
* There are no fix 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 set & make 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-line of the house; therefore it has further distance further distance than a Radiowave Frequency intercom, free from building material obstruction like concrete, and it has no EMF danger.
* Since voice travel via the power-line, all 2 pronged units must be plug into the same phase of the AC supply to communicate.If the system is plugged on to same phase of the wire, they are NOT on the same line, they will NOT communicate
* Power-line Intercom System uses the AC power line as the medium. It is subject to any interference already existed in the power-line, Just like your AC AM Radio. There is NO defectiveness with the system.
* Statics & noises interferences) were feed into power-line 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 Interference. 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 intercom was 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 is 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 building in North America.
* Power meter: In general utilities supply & billing, one household should have only one power-meter. Multiple power meters situation is common in some commercial units, when the tenant rents 2 units & joint them as one. In a residential situation, multiple power meters are possible with duplex. All power-line Intercoms transmit & receive within one power meter. This is a major security feature.
