Interface modules  
1 System description and  
One of two different interface modules can be mount-  
ed in the transmitter housing to connect the transmitter  
to a wide range of conference systems:  
planning  
1.1 System overview  
LBB 3423/20 Integrus DCN interface module to  
connect to the Digital Congress Network (DCN).  
LBB 3222/04 Integrus audio input and interpreters  
module to connect to analogue discussion and  
conference systems (such as CCS 800) or to  
LBB 3422/20 6-channel interpreters desks.  
Integrus is a system for wireless distribution of audio  
signals via infra-red radiation. It can be used in a  
simultaneous interpretation system for international  
conferences where multiple languages are used.  
To enable all participants to understand the proceed-  
ings, interpreters simultaneously translate the speaker’s  
language as required. These interpretations are distrib-  
uted throughout the conference venue, and delegates  
select the language of their choice and listen to it  
through headphones.  
Infra-red radiators  
Three types of radiators are available:  
LBB 3410/05 low power wide beam radiator for  
small conference venues  
LBB 4511/00 medium-power radiator for small/  
medium conference venues  
LBB 4512/00 high-power radiator for medium/large  
conference venues  
The Integrus system can also be used for music distri-  
bution (mono as well as stereo).  
All three types can be switched between full and half  
power use. They can be mounted on walls, ceilings or  
floor stands.  
Infra-red receivers  
Three multi-channel infra-red receivers are available:  
LBB 4540/04 for 4 audio channels  
LBB 4550/08 for 8 audio channels  
LBB 4540/32 for 32 audio channels

1.2 System technology  
The signal processing in the transmitter consists of the  
following main steps (see figure 1.3):  
1.2.1 IR radiation  
1. A/D conversion - Each analogue audio channel is  
converted to a digital signal.  
The Integrus system is based on transmission by mod-  
ulated infra-red radiation. Infra-red radiation forms  
part of the electro-magnetic spectrum, which is com-  
posed of visible light, radio waves and other types of  
radiation. It has a wavelength just above that of visible  
light. Like visible light, it is reflected from hard sur-  
faces, yet passes through translucent materials such as  
glass. The infra-red radiation spectrum in relation to  
other relevant spectra is shown in figure 1.2.  
2. Compression - The digital signals are compressed  
to increase the amount of information that can be  
distributed on each carrier. The compression factor  
is also related to the required audio quality.  
3. Protocol Creation - Groups of up to four digital  
signals are combined into a digital information  
stream. Extra fault algorithm information is added.  
This information is used by the receivers for fault  
detection and correction.

4. Modulation - A high frequency carrier signal is  
phase-modulated with the digital information  
stream.

5. Radiation – Up to 8 modulated carrier signals are  
combined and sent to the IR radiators, which con-  
vert the carrier signals to modulated infra-red light.

1.2.2 Signal Processing  
The Integrus system uses high frequency carrier signals  
(typically 2-8 MHz) to prevent interference problems  
with modern light sources (see section 1.3.2). The digi-  
tal audio processing guarantees a constant high audio  
quality.  
The standard quality mode uses less bandwidth and  
can be used for transmitting speech. For music the pre-  
mium quality mode gives near CD quality.

1.2.4 Carriers and channels  
The Integrus system can transmit up to 8 different car-  
rier signals (depending on the transmitter type). Each  
45  
45  
carrier can contain up to 4 different audio channels.  
The maximum number of channels per carrier is  
dependent on the selected quality modes. Stereo sig-  
nals use twice as much bandwidth as a mono signals,  
premium quality uses twice as much bandwidth as  
standard quality.  
90  
Per carrier a mix of channels with different quality  
modes is possible, as long as the total available band-  
width is not exceeded. The table below lists all possible  
channel combinations per carrier:

1.3.2 The footprint of the radiator  
1.3 Aspects of infra-red  
distribution systems  
The coverage area of a radiator depends on the num-  
ber of transmitted carriers and the output power of the  
radiator. The coverage area of the LBB 4512/00  
radiator is twice as large as the coverage area of the  
LBB 4511/00. The coverage area can also be doubled  
by mounting two radiators side by side. The total  
radiation energy of a radiator is distributed over the  
transmitted carriers. When more carriers are used, the  
coverage area gets proportionally smaller. The receiver  
A good infra-red distribution system ensures that all  
delegates in a conference venue receive the distributed  
signals without disturbance. This is achieved by using  
enough radiators, placed at well planned positions, so  
that the conference venue is covered with uniform IR-  
radiation of adequate strength.  
There are several aspects that influence the uniformity  
and quality of the infra-red signal, which must be con-  
sidered when planning an infra-red radiation distribu-  
tion system. These are discussed in the next sections.  
2
requires a strength of the IR signal of 4 mW/m per  
carrier to work without errors (resulting in a 80 dB  
S/N ratio for the audio channels). The effect of the  
number of carriers on the coverage area can be seen in  
figure 1.5 and figure 1.6. The radiation pattern is the  
area within which the radiation intensity is at least the  
minimum required signal strength.  
1.3.1 Directional sensitivity of the receiver  
The sensitivity of a receiver is at its best when it is  
aimed directly towards a radiator. The axis of maxi-  
mum sensitivity is tilted upwards at an angle of 45  
degrees (see figure 1.4). Rotating the receiver will  
decrease the sensitivity. For rotations of less than  
+/- 45 degrees this effect is not large, but for larger  
rotations the sensitivity will decrease rapidly.

The cross section of the 3-dimensional radiation pat-  
tern with the floor of the conference venue is known as  
the footprint (the white area in figure 1.7 to figure 1.9).  
This is the floor area in which the direct signal is  
strong enough to ensure proper reception, when the  
receiver is directed towards the radiator. As shown, the  
size and position of the footprint depends on the  
mounting height and angle of the radiator.  
1.3.3 Ambient lighting  
The Integrus system is practically immune for the  
effect of ambient lighting. Fluorescent lamps (with or  
without electronic ballast or dimming facility), such as  
TL lamps or energy saving lamps give no problems  
with the Integrus system. Also sunlight and artificial  
lighting with incandescent or halogen lamps up to 1000  
lux give no problems with the Integrus system.  
When high levels of artificial lighting with incandes-  
cent or halogen lamps, such as spotlights or stage light-  
ing are applied, you should directly point a radiator at  
the receivers in order to ensure reliable transmission.  
For venues containing large, unscreened windows, you  
must plan on using additional radiators.  
For events taking place in the open air a site test will  
be required in order to determine the required amount  
of radiators. With sufficient radiators installed, the  
receivers will work without errors, even in bright sun-  
light.

1.3.4 Objects, surfaces and reflections  
The presence of objects in a conference venue can  
influence the distribution of infra-red light. The texture  
and colour of the objects, walls and ceilings also plays  
an important role.  
Infra-red radiation is reflected from almost all surfaces.  
As is the case with visible light, smooth, bright or shiny  
surfaces reflect well. Dark or rough surfaces absorb  
large proportions of the infra-red signal (see figure  
1.10). With few exceptions it cannot pass through mate-  
rials that are opaque to visible light.

40%  
100%  
80%  
Figure 1.10 The texture of the material determines how  
much light is reflected and how much is  
absorbed  
Problems caused by shadows from walls or furniture  
can be solved by ensuring that there are sufficient radi-  
ators and that they are well positioned, so that a strong  
enough infra-red field is produced over the whole con-  
ference area. Care should be taken not to direct radia-  
tors towards uncovered windows, as most of this radia-  
tion will subsequently be lost.  
Figure 1.12 Infra-red signal not blocked by a person in front  
of the participant  
The figures below illustrate how infra-red radiation can  
be directed to conference participants. In figure 1.13,  
the participant is situated clear from obstacles and  
walls, so a combination of direct and diffused radiation  
can be received. Figure 1.14 shows the signal being  
reflected from a number of surfaces to the participant.  
1.3.5 Positioning the radiators  
Since infra-red radiation can reach a receiver directly  
and/or via diffused reflections, it is important to take  
this into account when considering the positioning of  
the radiators. Though it is best if receivers pick up  
direct path infra-red radiation, reflections improve the  
signal reception and should therefore not be min-  
imised. Radiators should be positioned high enough  
not to be blocked by people in the hall (see figure 1.11  
and figure 1.12).

Figure 1.14 Combination of several reflected signals  
Figure 1.16 Radiator positioning in a conference hall with  
auditorium seating and podium  
For concentrically arranged conference rooms, central-  
ly placed, angled radiators located high up can cover  
the area very efficiently. In rooms with few or no  
reflecting surfaces, such as a darkened film-projection  
room, the audience should be covered by direct path  
infra-red radiation from radiators positioned in front.  
When the direction of the receiver changes, e.g. with  
varying seat arrangements, mount the radiators in the  
corners of the room (see figure 1.15).  
If the audience is always directed towards the radia-  
tors, you do not need radiators at the back  
(see figure 1.16).  
If the path of the infra-red signals is partially blocked,  
e.g. under balconies, you should cover the ‘shaded’  
area with an additional radiator (see figure 1.17).  
Figure 1.17 Radiator for covering seats beneath a balcony  
The figures below illustrate the positioning of the  
radiators:  
1.3.6 Overlapping footprints and multipath  
effects  
When the footprints of two radiators partly overlap,  
the total coverage area can be larger than the sum of  
the two separate footprints. In the overlap area the sig-  
nal radiation power of two radiators are added, which  
increases the area where the radiation intensity is larg-  
er than the required intensity.  
However, differences in the delays of the signals  
picked up by the receiver from two or more radiators  
can result in that the signals cancel each other out  
(multi path effect). In worst-case situations this can lead  
to a loss of reception at such positions (black spots).

Figure 1.18 and figure 1.19 illustrate the effect of over-  
lapping footprints and differences in signal delays.  
1.4 Planning an Integrus infra-red  
radiation system  
1.4.1 Rectangular footprints  
Determining the optimal number of infra-red radiators  
required to give 100% coverage of a hall can normally  
only be done by performing a site test. However, a  
good estimation can be made by using ‘guaranteed rec-  
tangular footprints’. Figure 1.20 and figure 1.21 show  
what is meant by a rectangular footprint. As can be  
seen, the rectangular footprint is smaller than the total  
footprint. Note that in figure 1.21 the ‘offset’ X is nega-  
tive because the radiator is actually mounted beyond  
the horizontal point at which the rectangular footprint  
starts.

radiation power

angle of 15°  
H
Figure 1.19 Reduced coverage area caused by differences  
in cable signal delay  
The lower the carrier frequency, the less susceptible  
the receiver is for differences in signal delays.  
The signal delays can be compensated by using the  
delay compensation switches on the radiators  
(see section 1.5).  
Figure 1.21 A typical rectangular footprint for a mounting  
angle of 90°  
The guaranteed rectangular footprints for various num-  
ber of carriers, mounting heights and mounting angles  
can be found in section 7.6. The height is the distance  
from the reception plane and not from the floor.

en | 8  
Guaranteed rectangular footprints can also be calculat-  
ed with the footprint calculation tool (available on the  
documentation CD-ROM). The given values are for  
one radiator only, and therefore do not take into con-  
sideration the beneficial effects of overlapping foot-  
prints. The beneficial effects of reflections are also not  
included. As rule of thumb can be given for systems  
with up to 4 carriers, that if the receiver can pick up  
the signal of two adjacent radiators the distance  
between these radiators can be increased by a factor  
1.4 approximately (see figure 1.22).

When radiators are loop-through connected, the  
cabling between each radiator and the transmitter  
should be as symmetrical as possible (see figure 1.24  
and figure 1.25). The differences in cable signal delays  
can be compensated with the signal delay compensa-  
tion switches on the radiators.

1.4.2 Planning radiators  
Use the following procedure to plan the radiators:  
1. Follow the recommendations in section 1.3 in order  
to determine the positioning of the radiators.  
2. Look up (in the table) or calculate (with the foot-  
print calculation tool) the applicable rectangular  
footprints.  
3. Draw the rectangular footprints in the lay-out of the  
room.  
4. If the receiver can pick up the signal of two adja-  
cent radiators in some areas, determine the overlap  
effect and draw the footprint enlargement(s) in the  
lay-out of the room.  
Figure 1.24 Asymmetrical arrangement of radiator  
cabling (to be avoided)  
5. Check whether you have sufficient coverage with  
the radiators at the intended positions.  
6. If not so, add additional radiators to the room.  
See figure 1.15, figure 1.16 and figure 1.17 for examples  
of a radiator lay out.  
1.4.3 Cabling  
Signal delay differences can occur due to differences in  
the cable length from the transmitter to each radiator.  
In order to minimize the risk of black spots, use equal  
cable length from transmitter to radiator if possible (see  
figure 1.23).

1.5 Setting the radiator delay  
switches  
The next sections describe how to calculate the delay  
switch positions manually for systems with one trans-  
mitter, or two or more transmitters. See the delay  
switch calculation tool for the procedures how to calcu-  
late the delay switch positions automatically.  
As described in section 1.3.6, differences in the delays  
of the signals picked up by the receiver from two or  
more radiators can cause black spots as a result of the  
multi path effect.  
Tip: The delay switch calculation tool eases  
the calculation of the delay switch positions.  
The signals picked up by the receiver are delayed by:  
the transmission from transmitter to radiator  
through the cable (cable signal delay)  
the transmission from radiator to receiver through  
the air (radiation signal delay)  
for systems with two or more transmitters: the  
transmission through the slave transmitter(s)  
1.5.1 System with one transmitter  
1.5.1.1 Determining delay switch positions by  
measuring the cable lengths  
Use the following procedure to determine the delay  
switch position based on cable lengths:  
1. Look up the cable signal delay per meter of the  
used cable. The manufacturer specifies this factor.  
2. Measure the lengths of the cables between the  
transmitter and each radiator.  
3. Multiply the lengths of the cables between the  
transmitter and each radiator with the cable signal  
delay per meter. These are the cable signal delays  
for each radiator.  
To compensate the signal delay differences, the delay of  
each radiator can be increased. These signal delays can  
be set with the delay switches at the back of the radiator.  
The cable signal delays can be determined in the fol-  
lowing two ways:  
by measuring the cable lengths  
by measuring the impulse response time with a  
delay measurement tool  
4. Determine the maximum signal delay.  
5. Calculate for each radiator the signal delay differ-  
ence with the maximum signal delay.  
6. Divide the signal delay difference by 33. The  
rounded off figure is the signal delay switch posi-  
tion for that radiator.  
7. Add delay switch positions for radiators under a  
balcony, if applicable (see section 1.5.3).  
8. Set the delay switches to the calculated switch posi-  
tions.  
In both cases the cable signal delays can be calculated  
manually and with the delay switch calculation tool  
(available on the documentation CD-ROM).  
It is not necessary to calculate the cable signal delay in  
case:  
the radiators are directly connected to the transmit-  
ter with equal cable length;  
radiators are loop-through connected, but with less  
than 5 m distance between the first and last radiator  
in a trunk, and with equal cable length between the  
first radiator in each trunk and the transmitter.  
Caution: Turn the delay switches carefully  
to a new position until you feel that it  
clicks into position, to prevent that a  
switch is positioned between two num-  
bers, which would result in a wrong delay  
setting.  
In these cases set the delay switches on all radiators to  
zero and determine whether to compensate for radia-  
tion signal delay (see section 1.5.3).

1.5.1.2 Determining delay switch positions by  
using a delay measuring tool  
Note: For systems with a cable length dif-  
ference of more than 50 meters, it is rec-  
ommended to use a measurement tool to  
determine the delay differences in order  
to calculate the delay switch positions.  
The most accurate way to determine the cable signal  
delays is to measure the actual signal delay for each  
radiator as described in the following procedure:  
1. Disconnect the cable from a radiator output of the  
transmitter and connect this to a delay measure-  
ment tool.  
Figure 1.26 and table 1.1 illustrate the calculation of the 2. Disconnect a radiator from this cable.  
cable signal delay.  
3. Measure the impulse response time (in ns) of the  
cable(s) between the transmitter and the radiator.  
4. Reconnect the cable to the radiator and repeat  
steps 2 to 4 for the other radiators that are connect-  
ed to the same transmitter output.  
5. Reconnect the cable to the transmitter and repeat  
step 1 to 5 for the other radiator outputs of the  
transmitter.  
6. Divide the impulse response times for each radiator  
by two. These are the cable signal delays for each  
radiator.  
7. Determine the maximum signal delay.  
8. Calculate for each radiator the signal delay differ-  
ence with the maximum signal delay.  
9. Divide the signal delay difference by 33. The  
rounded off figure is the delay switch position for  
that radiator.

specified by the manufacturer.

clicks into position, to prevent that a  
switch is positioned between two  
numbers, which would result in a wrong  
delay setting.

4. Add the master-to-slave signal delay to each radia-  
tor connected to the slave transmitter.  
5. Determine the maximum signal delay.  
6. Calculate for each radiator the signal delay differ-  
ence with the maximum signal delay.  
7. Divide the signal delay difference by 33. The  
rounded off figure is the signal delay switch posi-  
tion for that radiator.  
Note: The calculated delay switch posi-  
tions based on impulse response time  
can differ from the calculated delay  
switch positions based on cable lengths.  
This is caused by the accuracy of the  
measurements and the accuracy of the  
cable signal delay factor per meter as  
specified by the manufacturer of the  
cable. If the impulse response time is  
measured correctly, the calculated delay  
switch positions will be the most accu-  
rate.  
8. Add delay switch positions to radiators under a bal-  
cony, if applicable (see section 1.5.3)  
9. Set the delay switches to the calculated delay switch  
positions.

1.5.3 System with more than 4 carriers and a  
radiator under a balcony  
Testing during a meeting  
1. Set a receiver in the Test-mode and select the high-  
est available carrier. The quality of the received car-  
rier signal is indicated on the display of the receiver  
(see section 4.3).  
2. Test all positions and directions (see next para-  
graph). The quality indication should be between  
00 and 39 (good reception).  
Figure 1.29 illustrates a situation in which a radiation  
signal delay occurs and which can be compensated for.  
For systems with more than four carriers, add one  
delay switch position per 10 meter (33 feet) difference  
in signal path length to the radiators which are closest  
to the overlapping coverage area. In figure 1.29 the sig-  
nal path length difference is 12 meter. Add one delay  
switch position to the calculated switch position(s) for  
the radiator(s) under the balcony.  
Testing all positions and directions  
With the transmitter and receiver in one of the two test  
modes, go around the conference hall and test the  
reception quality at every position where the infra-red  
signals must be received. When an area is detected  
where there is bad reception or even no reception at  
all, three main causes must be considered:  
16m  
4m  
Bad coverage  
The receiver can not pick-up infra-red radiation of ade-  
quate strength. This can be because the tested position  
is outside the footprint of the installed radiators or the  
radiation is blocked by obstacles such as a column, an  
overhanging balcony or other large objects.  
Figure 1.29 Radiation path length difference for two radiators  
1.6 Testing the coverage area  
Check that you used the correct footprints for the sys-  
tem design, that radiators with enough output power  
are installed and that a radiator is not accidentally  
switched to half power operation. When the bad recep-  
tion is caused by a blocked radiation path, try to  
remove the blocking obstacle or add an extra radiator  
to cover the shaded area.  
An extensive reception quality test must be done to  
make sure that the whole area is covered with IR radi-  
ation of adequate strength and that there are no black  
spots. Such a test can be done in two ways:  
Testing during installation  
1. Check that all radiators are connected and powered  
up and that no loose cables are connected to a radi-  
Black spots  
ator. Switch the transmitter off and on to re-initialise The receiver picks-up IR signals from two radiators  
the auto equalisation of the radiators.  
2. Set the transmitter in the Test-mode (see section  
2.5.7). For each channel, a different test tone fre-  
quency will be transmitted.  
3. Set a receiver on the highest available channel and  
listen via the headphones to the transmitted test  
tone.  
which cancel out each other. The multipath effect can  
be identified by the observation that the bad reception  
only occurs along a specific line and/or when good  
reception returns when the receiver is rotated to anoth-  
er direction. This can be confirmed by keeping the  
receiver in the position and direction with the bad  
reception and then either shading-off the radiation  
from one radiator with your hand or switching off one  
radiator. If this improves the reception quality, then the  
multipath effect is causing the problem. Note that IR  
radiation that is reflected from a surface with a high  
reflectabiliy can also cause multipath problems.  
4. Test all positions and directions (see next para-  
graph).  
Bosch Security Systems | 2005-04 | 3122 475 22015en  
 
INTEGRUS | Installation and User Instructions | System description and planning  
en | 14  
Black spots can occur in case a transmitter is located in  
the same room as the radiators. In that case, disable  
the mini IR radiator of the transmitter with the config-  
uration menu (see section 2.5.16).  
Check that the signal delay compensation switches on  
the radiators are set to the correct value and that a  
switch is not accidentally positioned between two  
numbers. Re-check your system design. When neces-  
sary, reduce the distance between the two radiators  
that cause the problem and/or add an extra radiator.  
Note that due to the physical characteristics of the sig-  
nal distribution, it is not always possible to completely  
avoid multi path effects.  
Interference from IR systems  
IR assistive hearing systems and IR microphones oper-  
ating at frequencies above 2 MHz, can disturb the  
reception at the lowest carriers. If such is the case,  
disable the lowest two carriers (see section 2.5.12) and  
re-check the reception.

The transmitter is the central element of the Integrus  
system. It accepts asymmetrical audio sources from a  
maximum of 32 external channels (dependent on the  
transmitter type) and can be used with the Digital  
Congress Network (DCN) and DCN Next Generation  
conference systems. It can also be used with analogue  
discussion and interpretation systems (e.g. CCS 800  
with up to 12 interpreter desks), or as a stand-alone  
system distributing external audio sources.  
The transmitter is suitable for either table-top or  
19-inch rack-mounted use. Four feet (for table top use)  
and two mounting brackets (for rack mounting) are  
supplied. The mounting brackets can also be used to  
mount the transmitter to a flat surface.  
Note: The mini IR-radiator and the head-  
phone output can also be permanently  
disabled by removing two resistors.

2.3.4 Connecting an emergency signal  
To use the emergency signal function, a switch (nor-  
mally-open) must be connected to the emergency  
switch connector. The reaction of the transmitter on a  
closed switch depends on the configuration of the aux-  
iliary inputs (see also section 2.5.14):  
Figure 2.14 Connecting an emergency signal  
2.3.5 Connecting to another transmitter  
The transmitter can be operated in slave mode to loop-  
through the IR radiator signals from a master transmit-  
ter. One of the four radiator outputs of the master  
transmitter is connected with an RG59 cable to the  
radiator signal loop-through input of the slave transmit-  
ter.  
If the auxiliary input is 'Mono + Emergency', the  
audio signal on the Aux-Right input is distributed  
to all output channels, overriding all other audio  
inputs.  
If the auxiliary input is 'Stereo' or 'Stereo to Mono',  
the audio signals on the Aux-Left and Aux-Right  
inputs are distributed to all output channels, over-  
riding all other audio inputs.  
The Transmission mode of the slave transmitter must  
be set to ‘Slave’ (see section 2.5.7).

ence system is switched off or defective.

dard/premium) can be set in sub-menu 4D. The quali-  
ty can be set the same for all channels or for each  
channel separately. Note that choosing stereo and/or  
premium quality uses more bandwidth and decreases  
the number of available channels (see section 1.2.4).  
In stereo mode, the left signal is always an even num-  
bered input. The next higher input number is used for  
the right signal.  
When the quality is set the same for all channels with  
the All Mono’ or All Stereo’ options, the inputs are  
assigned automatically to the channels as indicated in  
the table below:

First assemble the supplied suspension bracket and  
A radiator consists of two IRED panels. Each IRED  
panel has an amber and a red indicator LED (see  
figure 3.2) which show the status of the radiator panel  
connect it to the radiator (see figure 3.3 and figure 3.4).  
This bracket is attached to the radiator by two bolts  
with washers. There are corresponding holes on the  
back of the radiators. There is also a spring-loaded  
plunger (indicated by a black arrow in figure 3.4),  
located above the bolt hole on the right-hand arm of  
the bracket, which is used for adjusting the angle of the  
radiator (shown in inset in figure 3.4). There are corre-  
sponding holes on the back of the radiator for accept-  
ing this plunger. The mounting angle can be adjusted  
in steps of 15°.

3.1.3 Mounting the radiators  
Radiators in permanent installations can be either fixed  
to a wall, hung under a ceiling or balcony or secured  
to any sturdy material, using the suspension bracket  
supplied with the radiator. The mounting angle can be  
adjusted for optimal coverage.  
For wall mounting a separate bracket (LBB 3414/00) is  
also required. In non-permanent installations, a floor  
stand can be used.  
Figure 3.3 Attaching the plate to the suspension bracket  
Warning: When you install the radiator in  
a ceiling, you must leave at least 1 m3 of  
free space around the back of the radia-  
tor. To prevent the radiator from becom-  
ing too hot, make sure that there is a  
good airflow in this free space.  
Note: When in operation, the radiators  
may feel warm to the touch. This is quite  
normal, and does not indicate a radiator  
fault or malfunction.  
Warning: Always ensure that natural air-  
flow is not obstructed by ceilings, walls  
etc. when determining the position of the  
radiator. Leave plenty of space around the  
radiator to prevent it becoming too hot.

Mounting on a floor stand  
Wall mounting  
For wall mounting, an extra wall bracket (LBB  
The top of the floor stand is screwed into the suspen-  
sion bracket (figure 3.5). The bracket is supplied with  
both metric and Whitworth threaded plates, and is  
therefore compatible with most standard floor stands.  
For floor stands, the mounting angle can be set at 0°,  
15° or 30°.  
3414/00) is required (must be ordered separately).  
This bracket is attached to the wall by means of four  
bolts (see figure 3.8). Four holes of 10 mm in diameter  
and 60 mm in depth must be drilled using the drilling  
pattern (see figure 3.7).  
Note: The four bolts used to attach the  
bracket must each be able to withstand  
a pull-out force of 200 kg (440 lb).  
The bolts and plugs delivered with the  
LBB 3414/00 wall bracket are only intend-  
ed for mounting the unit on a solid brick  
or concrete wall.

INTEGRUS | Installation and User Instructions | Integrus Radiators  
en | 45  
The radiator (plus suspension bracket) is attached to  
the wall bracket by sliding the mounting bolt over the  
slot on the wall bracket and then tightening it (see  
figure 3.9). A split pin is then inserted into a small hole  
in the bolt to stop it from working loose (see inset in  
figure 3.9). The vertical angle of the radiator can be  
adjusted between 0 and 90° in steps of 15°. The hori-  
zontal orientation of the radiator can be adjusted by  
loosening the bolt then turning the radiator to the  
required position.  
Ceiling mounting  
The radiators can be attached to the ceiling using the  
supplied suspension bracket. This ensures enough  
space for a proper air flow around the radiator.  
Mounting a radiator in the ceiling will in most cases  
require a forced air flow by means of a ventilator to  
prevent overheating.  
Mounting on horizontal surfaces  
When the radiator has to be positioned a horizontal  
surface (e.g. on top of an interpreter booth), the dis-  
tance between the radiator and the surface must be at  
least 4 cm (1.5 inch) to enable enough air flow around  
the radiator. This can be achieved by using the suspen-  
sion bracket as a support. If this is not possible, switch  
the radiator to half power. If the radiator is used at full  
power on top of an interpreter booth, the ambient tem-  
perature must not exceed 35° C.  
3.1.4 Connecting radiators to the transmitter  
The transmitter has six BNC HF Output connectors  
labelled 1, 2, 3, 4, 5 and 6 on the rear panel. All six  
outputs are functionally identical. They can each drive  
up to 30 radiators (LBB 4511/00 and/or LBB 4512/00)  
in a loop-through configuration. The radiators are con-  
nected with RG59 cables. The maximum cable length  
per output is 900 m (2970 ft) to the last radiator.  
Automatic cable termination is achieved by a built-in  
switch in the BNC connectors on the radiator.  
Figure 3.8 Attaching the wall mounting bracket to a wall  
Notes:  
For the automatic cable termination to  
work, never leave an open-ended  
cable connected to the last radiator in  
a loop-through chain.  
When connecting infra-red radiators,  
do not split the cable, else the system  
will not function correctly.

3.2 Low Power Wide Beam Radiator  
3.2.1 Description  
This radiator is designed for small or medium-sized  
conference venues. The radiator has an infra-red out-  
put of 3 Wpp and they have a built-in power supply  
and are switched on automatically when the transmitter  
is switched on. A mains cable is provided. When not  
receiving carrier waves, the radiators switch to standby  
mode. They can be mounted on walls and ceilings or  
on a floor stand. Figures 3.11 and 3.12 show front and  
rear views of the radiators.  
Figure 3.11 LBB 3410/05 Radiator (Front view)  
Figure 3.10 Loop-through connection of radiators  
3.1.5 Using the output power selection  
switch  
The radiators can be switched to half power. This can  
be used when full power is not required, e.g. when a  
mobile system is used in a small conference venue.  
Also switch a radiator to half power when an adequate  
air flow can not be guaranteed, e.g. when the radiator  
is mounted on top of an interpreters booth. Reducing  
the power when possible saves energy and increases  
the lifetime.

The following are found on the radiator printed circuit  
board: (Figure 3.13):  
Don’t use this radiator in combination with LBB  
4511/00 and LBB 4512/00 radiators in one system,  
as the internal signal delay of these radiators are  
different.  
No automatic cable termination: the termination  
plug has to be connected to the last radiator in a  
trunk.  
No communication of the radiator status to the  
transmitter.  
Using this radiator at 105 to 125 V requires internal  
adjustments.

3.2.2 Radiator Status Indication  
When the radiator is transmitting, a green LED mount-  
ed internally on a printed circuit board illuminates. If  
there is a failure in the radiator, a red LED illuminates  
on the printed circuit board.  
5. Green LED - indicates that the radiator is switched  
on and is receiving carrier waves from the transmitter.  
6. Red LED - indicates that the radiator output is 70%  
or less of the normal output level.  
3.2.3 Mounting the Radiator  
Mains voltage selection of 115 V or 230 V is internally  
selectable. On delivery the radiator is set for 230 Va.c.  
operation. To alter the mains voltage selection for the  
LBB 3410/05 radiators, it is necessary to solder two  
leads to contacts on the printed circuit board (PCB)  
inside the radiator. To locate the PCB, remove the four  
securing screws at the rear of the radiator and remove  
the unit from its housing. Remove the PCB from its  
mounting by removing the PCB’s six securing screws  
and the small connector X1 (figure 3.13). To select  
115 V operation, solder two small leads, one connect-  
ing X4 to X6 and one connecting X5 to X7. Then  
remove the small SMD resistor R3. When this is com-  
pleted replace fuse F1 (160 mA) with a fuse rated at  
350 mA.  
Radiators in permanent installations can be fixed to a  
wall, hung under a ceiling or balcony or secured to  
any sturdy material using the unit’s built-in bracket and  
mounting adaptor supplied with the radiator (figure  
3.14). In non-permanent installations, a floor stand can  
be used. The mounting adaptor enables the radiator to  
be positioned for optimum performance.  
Limitations:  
Not more than the first 4 carriers can be transmit-  
ted.  
Not more than 100 m cable length from transmitter  
to last radiator.  
Directly connection of the radiators to the transmit-  
ter with equal cable length. In loop-through con-  
nection, the total cable length from the first to the  
last radiator may not exceed 5 meters. Reason:  
there are no facilities on this radiator for compen-  
sating the cable signal delay.

4.2 Operation  
Note: Disposable batteries and battery  
packs at the end of their technical lives  
should be discarded with due care for  
the environment. When possible, take  
batteries to a local recycling station.  
The receiver cannot operate when no headphone is  
connected. After connecting the headphone the receiv-  
er switches to stand-by mode. Push shortly on the  
on/off button to switch the receiver on.  
The channel number is shown on the LCD display.  
The channel can be changed with the channel selector.  
Push it to the up- or down-position to increase or  
decrease the channel number. The highest channel  
number is automatically matched to the number of  
channels that has been set on the transmitter (see sec-  
tion 2.5.9).  
4.3 Reception test mode  
The receivers can be switched to a test-mode to get an  
indication of the reception quality for each carrier sep-  
arately. To activate the test-mode: Push the channel  
selector to the Up-position, press the on/off button and  
hold both for ca. 2 seconds. When in test-mode,  
switch between carriers by using the channel selector.  
The receiver’s display will shortly show the carrier  
number (0-7) and then a quality indication (00-90).  
A battery symbol is visible on the display when the  
batteries or the battery pack is almost empty.  
An antenna symbol is visible when the receiver picks  
up a modulated infra red signal of adequate quality.  
During short interruptions in the reception, the receiv-  
er mutes the headphones output. When no adequate  
IR signal is detected for more than 1 minute (e.g.  
when a delegate leaves the conference room), the  
receiver automatically switches to stand-by mode.  
The volume can be changed by moving the volume  
control up or down.  
Note: When the receiver does not receive  
the selected carrier, it keeps displaying  
the carrier number and does not display  
its quality.  
The receiver can be manually switched to stand-by  
mode by pressing the on/off button for more than 2  
seconds.  
When the headphone is disconnected, the receiver is  
automatically switched off. (A switch in the headphone  
connector disconnects the batteries.)  
The reception quality can be assessed as follows:  
Indication  
Quality  
00-39  
40-49  
50-90  
Good reception. Very good audio quality.  
Weak reception. Ticks in the audio.  
The infra-red receivers can operate with disposable  
batteries (2x AA-size alkaline cells) or with a recharge-  
able battery pack (LBB 4550/00).  
No or bad reception. Poor audio quality.  
Insert the batteries or the battery pack in the receiver  
with the correct polarity as indicated in the battery  
compartment. The battery pack has a separate connec-  
tion cable which must be connected to the receiver.  
When this connection is not present, the charging cir-  
cuitry in the receiver will not work. This also prevents  
the unwanted charging of disposable batteries. The bat-  
tery pack has a temperature sensor which prevents  
overheating during charging.  
The test mode is deactivated when the receiver is  
switched off.  
4.4 Receiver headphones  
The headphones connect with the receivers via a 3.5  
mm (0.14 inch) stereo jack connector. Suitable head-  
phone types are:  
LBB 3441/10 Under the chin stereo headphones  
LBB3442/00 Single earphone (mono)  
LBB3443/00 Stereo headphones (recommended)  
Or any other compatible type (see chapter 7,  
Technical Data).  
For more information about charging the battery pack  
see chapter 5.

5.2 Wall mounting the charging  
cabinet  
5.3 Charging procedure  
Ensure that the charging unit is connected to the mains  
and that it is switched on. Place the receivers firmly in  
the charging compartments. The charging indicator  
LEDs on all receivers should illuminate. These LEDs  
indicate the charging status of each receiver:  
LBB 4560/50 is suitable for either table-top or wall-  
mounted use.  
It can be wall-mounted using 5 mm (0.19 inch) screws,  
with a head diameter of 9 mm (0.35 inch). The screws  
and plugs delivered with the LBB 4560/50 are  
designed to mount the unit on a solid brick or concrete  
wall. Two holes, 8 mm in diameter and 55 mm in  
depth, must be drilled 500 mm apart (see figure 5.2).

Warning: To comply with UL and CSA  
regulations, the charging cabinets must  
be mounted in such a way that they can  
be easily removed by hand in case of  
emergency.  
Notes:  
It is preferred to switch on the charg-  
ing unit before inserting the receivers.  
Receivers can be inserted or removed  
without damage while the charging  
unit is switched on.  
Charge the battery pack to full capaci-  
ty before using them for the first time.  
The charger always applies fast  
charge during the first 10 minutes  
after inserting a receiver. Inserting the  
receiver multiple times with a fully  
charged battery pack should therefore  
be avoided, as this will damage the  
battery pack.  
Figure 5.2 Charging cabinet mounting dimensions  
Continuously charging the receiver  
will not damage the receiver or bat-  
tery pack. Receivers can therefore  
safely be left in their charging posi-  
tions when they are not used.  
When the rechargeable battery pack  
is used, it is advisable to check regu-  
larly after three years that the batter-  
ies are not leaking. If there is any sign  
of leakage or corrosion, replace the  
battery pack. Ensure that only the bat-  
tery pack LBB 4550/00 is used. The  
battery pack has to be replaced at  
least every five years.

Check that the emergency contact is connected correctly.  
Check that the audio is connected according to the selected auxiliary input  
mode (menu 4I).  
Red LED flashes and amber LED is on of one  
or both IRED panels of a radiator:  
IRED panel is in temperature protection mode. Check that the natural air-  
flow around that radiator is not obstructed. If not so, replace the radiator.  
Both red LED and amber LED are on of one or  
both IRED panels of a radiator:  
IRED panel malfunctions and the radiator should be replaced.  
Infra red receiver fails to function properly:  
If disposable batteries are used, check whether the batteries have suffi-  
cient capacity and whether they are inserted with the correct polarity.  
If a battery pack is used, ensure that the battery pack is fully charged.  
Ensure that the headphone is connected properly.  
Switch the receiver on and check whether the display indicates a channel.  
Ensure that the receiver picks up sufficient IR signal and check whether  
the antenna symbol becomes visible.  
Enable the mini radiator (menu 4M) and check the receiver by holding it in  
front of the mini radiator of the transmitter.  
Ensure that the volume control is turned up.  
Set the transmitter in test mode and check whether the test tone is audible  
on the receiver.  
If the test tone is not audible, do the same test with other receivers.  
If all receivers do not work properly at that spot, check the coverage of the  
system (see section 1.6).
