2.4 Mounting  
The LBB 4141/00 and LBB 4141/50 voting units can  
be snap-mounted and block mounted.  
2.4.1 Snap Mounting  
The snap-mounting method is used to install flush-  
mounting units in panels with a thickness of 2 mm.  
This method uses the ‘click-to-fit’ mechanism to secure  
the units in cutouts in tabletops or the armrest of seats.  
See Figure 2.1 for a close up of the click-to-fit  
mechanism and Figure 2.9 for the dimensions for snap  
mounting.  
Figure 2.6 Changed Voting Button Order LBB 4141/00  
To change the voting button order:  
1
Unscrew the front plate of the voting unit. Keep  
the two screws.  
2
Remove the three buttons in the middle of the  
unit by squeezing the snap fingers of the buttons  
with a pair of tweezers.  
3
Insert the buttons in the correct position. (see

5
Fasten the PCB back to the front plate.  
Set the button order jumper on position 1 (see  
Figure 2.8 Click-to-fit mechanism

The default position of the button order jumper is:  
LBB 4141/00: position 2  
LBB 4141/50: position 1  
Figure 2.9 Dimensions for snap mounting  
2.4.2 Block Mounting  
i
Note  
The block-mounting method is used to install flush-  
mounting units in surroundings of more than 2 mm.  
This method uses couple pieces (LBB 4127/00) to flush  
mount the voting units in cutouts in tabletops, metal  
plates or armrests of seats. The end caps (LBB 4125/00)  
cover the coupling pieces and complete the attractive  
design.  
The voting unit can not be used for audience  
response voting, multiple choice voting, opinion  
poll voting and rating, when the button order  
jumper is set to position 1.  
See Figure 2.10 for the procedure for block mounting a  
voting unit and Figure 2.11 for the dimensions for block

mounting. In stage 3: fasten the screws of the coupling  
pieces, in order to fixate the coupling pieces.  
2.4.3 De-mounting  
Follow the mounting procedure in reverse. Use a  
spatula to remove the end caps and a screwdriver to  
unlock the click-to-fit mechanism of the voting unit.

i
Note  
Take care not to damage the furniture while  
removing the end caps and voting unit. Replace  
the end caps in case those are damaged.  
2.5 Connecting  
The LBB 4141/00 and LBB 4140/50 voting units can  
be directly connected to the trunk line in a loop-  
through chain (see Figure 2.12).  
See the DCN Installation and Operating Manual for  
the system limits and for how to design and install a  
DCN system.

i
Note  
An unused output cable must be terminated by  
an LBB 4118/00 Termination Plug.  
2.6 Initializing  
When all the units in a system have been installed,  
the system must be initialized and made ready for use  
once. The initialization procedure enables all DCN  
units installed to be recognized by the CCU.  
Recognition is given in the form of an address,  
allocated by the CCU to each active unit in the  
system.  
See chapter 11 of the DCN Installation and  
Operating Manual for how to initialize and assign  
seat numbers in a PC-based system.

2.6.1 De-initialization of a System  
Systems, which are powered-up for the first time, are  
de-initialized. All LEDs of the de-initialized units  
illuminate. In case some of the units are not in this  
state, de-initialize these units or de-initialize the  
system. See chapter 11 of the DCN Installation and  
Operating Manual for how to de-initialize a system.  
2.6.2 De-Initialization of Individual Voting Units  
To de-initialize an individual unit, press the de-  
init/init switch shortly (see Figure 2.13). All LEDs of  
the de-initialized unit illuminate. To de-initialize and  
initialize an individual unit at the same time, keep the  
de-init/init switch pressed for a longer time.  
Figure 2.15 Initialization LBB 4141/50  
2.6.4 Replacing a Voting Unit  
Press the de-init/init (see Figure 2.13) switch while  
connecting a replacement unit. The unit will be de-  
initialized and initialized during connection. Once  
the unit is recognized in the system, the unit active  
indicator illuminates.  
2.6.5 Re-installing a Temporary System  
The units hold their addresses when the units are  
disconnected. It is not necessary to de-initialize the  
system, in case the same units are reconnected after  
being stored. In case the units have been used in  
another system in the meantime, follow the  
procedures described in order to de-initialize the  
system and initialize the units.  
Figure 2.13 De-Initialization LBB 4141/xx Voting Unit  
2.6.3 Initialization of Individual Voting Units  
To initialize an individual unit, press the button in  
the middle of the voting unit (see Figure 2.14 and  
Figure 2.15) or the de-init/init switch (see Figure  
2.13). The units LEDs go out. Once the unit is  
recognized in the system, the unit active indicator  
illuminates. Repeat this procedure for all active units  
installed in the system one by one.  
i
Note  
In case the temporary system is a Multi CCU  
system, reconnect the units to the same CCU  
as during initialization in order to eliminate  
address conflicts or de-initialize the system.  
i
Note  
2.7 Commissioning  
To check whether a system with LBB 4141/xx voting  
units works properly:  
Initialize the units one by one (and not  
simultaneously) in order to eliminate address  
conflicts.  
1. Start a voting (see paragraph 2.8.6)  
2. Register presence and vote yes on all units (see  
paragraph 2.8.6). See paragraph 2.9 in case a  
voting unit is not working properly.  
3. Check the voting results. If the voting results are  
incorrect: determine which voting unit causes the  
wrong results. Correct the position of the voting  
button order jumper (see paragraph 2.3).

see paragraph 2.9.1 for troubleshooting.  
Figure 2.19 Presence Registration LBB 4141/50  
In case the option “registration at entrance/exit unit”  
is selected, the voting unit will stay inactive until the  
delegate assigned to that unit is registered present  
(e.g. registered with a chip card).  
Figure 2.16 Unit Active Indication LBB 4141/00  
2.8.5 Voting Authorization and Access Control  
A PC is required for voting authorization and access  
control. The operator specifies whether individual  
delegates are allowed to take part in electronic voting  
and initiates access control. See the manual of LBB  
3580 Delegate Database and LBB 3578 Attendance  
Registration and Access Control.  
In case access control is enabled for voting, the  
voting unit will stay inactive if the delegate assigned  
to that unit has no voting authorization.  
Figure 2.17 Unit Active Indication LBB 4141/50  
2.8.4 Attendance Registration  
2.8.6 Voting  
A PC is required for attendance registration. The  
operator initiates attendance registration. See the  
manual of LBB 3578 Attendance Registration and  
Access Control.  
The user interaction of the voting units in a stand-  
alone system is described in this paragraph. See the  
manuals of LBB 3575 Parliamentary Voting and LBB  
3576 Multi Voting for other options.

If the unit active indicator does not illuminate:  
1. Check whether the unit is connected.  
2. Follow the general trouble shooting procedure  
(see paragraph 2.9.4).  
2.9.2 Address Conflict  
In some cases the voting unit cannot detect an  
address conflict. Symptoms of a voting unit with an  
address conflict:  
The number of units detected by LBB 3585  
System Installation software is less than the  
actual number of units installed.  
The voting unit does not respond.  
The voting unit responds to key presses on  
another unit.  
Figure 2.20 Parliamentary Voting LBB 4141/00  
In case a voting unit is not responding correctly:  
1. De-initialize and initialize the unit (see paragraphs  
2. Follow the general trouble shooting procedure (see  
Figure 2.21 Parliamentary Voting LBB 4141/50  
2.9.3 Disconnect Indication via a PC

Software displays which unit is disconnected (see  
To vote, press the yes, no or abstain button. The  
LED above the pressed button illuminates. To  
change your vote, press one of the other buttons.  
The voting unit is represented as if it is a delegate  
unit.  
When the chairman holds the voting, the voting unit  
becomes inactive and the LEDs go out. When the  
chairman restarts the voting, the LEDs return to their  
previous state.  
Once the chairman stops the voting session, the  
voting session is finished and the LEDs go out.  
2.9 Troubleshooting  
2.9.1 Fault Indication on a Voting Unit  
The unit active indicator flashes in case the unit  
detects a communication fault.  
If the unit active indicator flashes:  
1. Press the button in the middle of the voting unit  
shortly (see Figure 2.14 and Figure 2.15). In case  
all LEDs of the unit illuminate, the unit is de-  
initialized and the problem was caused by an  
address conflict. Press the button in the middle of  
the voting unit in order to initialize the voting  
unit. Once the unit is recognized in the system,  
the unit active indicator illuminates and the  
address conflict is solved.
