Some more useful
information about our intercoms.
In our FM wireless intercom system, mainly we have Two/Three type of transmission:
1. Power line transmission. In this type intercom, communication signal
passing via your 230V/110V power supply line.
Advantage: This model intercom will work with in your 110/230V power distribution
transformer on one phase line. (they may have total three phase) and
you will get more range. only required two pin AC outlet for plug the intercom.
Disadvantage. This model work only with in same phase line, not work perfectly
to other phase lines. and some voice disturbance may happen when working
some other domestic electrical/electronic equipment.
2. Transmission via Earth/ground and neutral wire. In this type intercom,
communication signal passing via earth and neutral of your power supply
wiring. Not using phase line.
Advantage: This model intercom will work all three phase line. No voice
disturbance happening when using other electrical/electronic equipment.
Disadvantage. This model will work all three phase line. But Required 3
pin AC outlet with earth connection for working this model intercom. Because
we using 3 core power cable. Not work with out earth/ground connection of
your house wiring.
If power supply neutral wire connected to ground in your building, the Intercom
will not work to out side of the building or in between building.
3. "Single Core Wired" Intercom. You can also convert Earth Line model
to this:
This model will work even if in different transformer or phase. Guaranteed
working. and also you will get up to 100KM range. You can also use any existing
wire like Land Telephone cable or old intercom wiring or Cable TV wire outer
shield etc... Because through this wire only passing RF signal. No any high
Voltage
If you choose earth line model, you can also convert it to power line model
and also single core wired model your self. Price for three models are same.
