For UDS panels two specific Type ID are reserved, UDS1 and UDS2. 
UDS units can be installed from the tenth starting address with the exclusion of the decade from 0 to 9, and 
occupy from a minimum of 2  to a maximum of 6 addresses. 
The basic installation, compatible with UDS-1N type units ( now obsolete ) , occupies the first two addresses to 
which the  type-ID UDS1 is assigned; the operation is allowed only on the first address but is automatically 
extended to the second address.  
In the subsequent four addresses the optional modules which have been introduced with the UDS-2N and the 
present UDS-3N unit  can be installed; to perform this operation just insert the  type-ID = UDS2. 
For a detailed description of the functionalities associated with the interface modules with UDS units consult the 
relevant manuals. 
 
For UDS modules, the following specific indications are obtained:  
 
   Address    Type ID  Description and signallings 
 
1st  address (X0)*     UDS1    “ALL1” 
2nd  address (X1)*  UDS1    “ALL2” 
3rd  address (X2)*  UDS2    “GEN_FAULT” (General fault on UDS-2N) 
4th  address (X3)*   UDS2    “EXT_FAULT” (Anomaly on the extinguishing line of the UDS-2N  panel) 
5th  address (X4)*   UDS2   “AUT_DIS” (disabling of the UDS-2N  panel) 
6th  address (X5)*   UDS2    “POW_FAULT” (Fault for no 230 Vac  power supply  on UDS-2N panel) 
 
N.B. : 
*  X  can have the values from 1 to 9 
 
UDS unit removal 
The UDS unit is completely removed (including the optional UDS2 modules possibly installed) by re-setting the  
type-ID NONE on the first address.  
This is also the only system to remove the type-ID UDS 1;  UDS2 type modules can be also removed one by 
one. 
 
 Fault event signals from  UDS panels connected to the AM-8000 control unit 
  Key selector on UDS-3N in  “Manual” or “Disabled” position in AM-8000 control unit; there will be the 
following signallings: 
Yellow led “Exclusions” lit. 
The symbol 
“ ! ” is on the control unit state icon. 
In the  system exclusion list display there is the indication “ Excl UDS Addr XX” where  XX is 
 the first address assigned to the UDS-3N panel. 
 
  General Fault on the UDS-3N panel in AM-8000 control unit; there will be the following signallings: 
Yellow led “FAULTS” flashing 
The symbol 
“  ” on the control unit state icon. 
The display shows the indication “UDS XX GEN” where  XX is the third address (with 
description “GEN_FAULT”) assigned to the UDS-3N panel. 
 
  In case of Anomaly on the extinguishing line of  UDS-3N panel in  AM-8000 control unit; there will be 
the following signaling:  
Yellow led “FAULTS” flashing 
The  symbol
“  ” is on the control unit state icon.  
The display shows the indication “US XX : Fault EXTING” where XX is the fourth address (with 
description “EXT_ FAULT”) assigned to the UDS-2N panel. 
In case of no 230 Vac power supply on the USD-3N panel in AM4000 control unit there are the 
following signaling: 
 Yellow led “FAULTS” flashing 
The symbol 
“  ” is on the control unit state icon.   
The display shows two indications: 
“UDS XX : GEN FAULT“ where XX is the third address (description “GEN_FAULT”).  
“UDS XX : POWER FAULT.” where XX  is the sixth address (description “POW_FAULT” )
