ADDRESSES OF CONTROL PANELS
If two or more control panels are connected to the system, the addresses of the control panels have to be changed.
Example: 3 control panels
- Connect the first control panel to the unit and change its address to 3.
- Connect the second control panel to the unit and change its address to 2.
- Connect the third control panel to the unit and check to see if its address is 1.
If control panels have the same address, they go to bus fault state. In this case, remove the second control panel
and change the address of the second control panel. Such a situation can occur in connection with the later in-
stallation of an additional control panel.
