To understand how we obtain this compatibility, remember that almost all electronic door-entry systems in the world have used similar designs for their 4+n telephones.
In general terms, there are two different operating types for the audio system. These types are:
- COMMON NEGATIVE SYSTEM
- SEPARATED NEGATIVE SYSTEM
and two different types of call generators:
- RING CALLING SYSTEM
- ELECTRONIC CALLING SYSTEM
These telephone’s circuits allow you to, by changing the position of some incorporated bridges or switches (depending on the model), configure the telephones as:
- Electronic Call or Ring call
- Common Earth or separated Earth
Besides detailing it in the included instructions, there is a table of compatible telephones from other brands and their connection.
