ACTIVATING THE SYSTEM
Perform the following operations in order after wiring the devices:
1. Set up the line terminations.
2. Confi gure the devices using the dip-switches.
3. Switch on power and check voltage.
4. Check the system.
5. Associate door unit button to users or program calling module name directory.
6. Run basic functional test.
7. Program the door units and/or the apartment stations when required after the steps above.
1 LINE TERMINATION SETTINGS (Z)
Refer to the previous chapter for correct Z line termination settings.
Default settings
All door phones are confi gured by default with line termination on.
All brackets are confi gured by default with line termination on.
All distributors are confi gured by default with line termination off.
All column interfaces are confi gured by default with line termination on (jumper between Z terminal
present).
The line terminal on/off jumper (Z) is not present on some video door phones (e.g. 1750/1, 1750/5,
1750/6).
In this manner, in the typical case of system with calling station connected directly to the power supply unit
and apartment stations connected as fl oor extensions to a column, only the jumper of the termination of the
last distributor needs to be changed to the ON position.
2 DEVICE CONFIGURATION
The confi guration can be made also when the system is not powered because dip-switches on the door unit
and apartment stations and interface columns are used.
