Important safeguards
1 Read instructions - All the safety instructions for use
should be read before the system is operated.
2 Retain instructions - The safety instructions and
instructions for use should be retained for future
reference.
3 Heed warnings - All warnings on the unit and in the
operating instructions should be adhered to.
4 Follow instructions - All operating instructions and
instructions for use should be followed.
5 Cleaning - Unplug system units from the mains outlet
before cleaning. Do not use liquid cleaners or aerosol
cleaners. Use a damp cloth for cleaning.
6 Attachments - Do not use attachments not
recommended by the product manufacturer as they may
cause hazards.
7 Water and Moisture - Do not use this unit near water, for
example near a bathtub, washbowl, kitchen sink, or
laundry basket, in a wet basement, near a swimming
pool, in an unprotected outdoor installation or any area
which is classified as a wet location.
8 Accessories - Do not place this unit on an unstable stand,
tripod, bracket or mount. This unit may fall, causing
serious injury to a person and serious damage to the
unit. Use only a stand, tripod, bracket or mount
recommended by the manufacturer, or sold with the
product. Any mounting of the unit should follow the
manufacturer's instructions, and should use a mounting
accessory recommended by the manufacturer. An
appliance and cart combination should be moved with
care. Quick stops, excessive force, and uneven surfaces
may cause the appliance and cart combination to
overturn.
9 Ventilation - Openings in the enclosure, if any, are
provided for ventilation and to ensure reliable operation
of the unit and to protect it from overheating. These
openings must not be blocked or covered. The unit
should not be placed in a built-in installation unless
proper ventilation is provided or the manufacturer's
instructions have been adhered to.
10 Power sources - Units should be operated only from the
type of power source indicated on the marking label. If
you are not sure of the type of power supply you plan to
use, consult your appliance dealer or local power
company. For units intended to operate from battery
power, or other sources, refer to the "Installation and
User Instructions".
11 Grounding or polarisation - This unit may be equipped
with a polarised alternating current line plug (a plug
having one blade wider than the other). This plug will fit
into the power outlet only one way. This is a safety
feature. If you are unable to insert the plug fully into the
outlet, try reversing the plug. If the plug still fails to fit,
contact your electrician to replace your obsolete outlet.
Do not defeat the safety purpose of the polarised plug.
Alternatively, this unit may be equipped with a 3-wire
grounding type plug having a third (grounding) pin.
This plug will only fit into a grounding-type power
outlet. This is a safety feature. If you are unable to insert
the plug into the outlet, contact your electrician to
replace your obsolete outlet. Do not defeat the safety
purpose of the grounding-type lug.
Bosch Security Systems | 2003-09 | 3922 988 25012en
12 Power-Cord Protection - Power supply cords should be
routed so that they are not likely to be walked on or
pinched by items placed upon or against them, paying
particular attention to cords and plugs, convenience
receptacles, and the point where they exit from the
appliance.
13 Overloading - Do not overload outlets and extension
cords as this can result in a risk of fire or electrical shock.
14 Object and Liquid Entry - Never push objects of any
kind into this unit through openings as they may touch
dangerous voltage points or short-out parts that could
result in a fire or electric shock. Never spill liquid of any
kind on the unit.
15 Servicing - Do not attempt to service this unit yourself as
opening or removing covers may expose to dangerous
voltage or other hazards. Refer all servicing to qualified
service personnel.
16 Damage Requiring Service - Unplug the unit from the
outlet and refer servicing to qualified service personnel
under the following conditions:
• When the power-supply cord or plug is damaged.
• If liquid has been spilled, or objects have fallen into
the unit.
• If the unit has been exposed to rain or water.
• If the unit does not operate normally by following
the instructions for use. Adjust only those controls
that are covered by the instructions for use, as an
improper adjustment of other controls may result in
damage and will often require extensive work by a
qualified technician to restore the units to their
normal operation.
• If the unit has been dropped or the unit has been
damaged.
• When the unit exhibits a distinct change in
performance; this indicates a need for service.
17 Replacement Parts - When replacement parts are
required be sure the service technician has used
replacement parts specified by the manufacturer or parts
which have the same characteristics as the original part.
Unauthorised substitutions may result in fire, electric
shock or other hazards.
18 Safety Check - Upon completion of any service or
repairs to the units, ask the service technician to perform
safety checks to determine that the unit is in proper
operating condition.
19 Lightning - For added protection of the units during a
lightning storm, or when it is left unattended and unused
for long periods of time, unplug it from the wall outlet
and disconnect the cable system. This will prevent
damage to the unit due to lightning and power-line
surges.

The Plena BGM/Paging System is the all-in-one solution for making announcements, paging people and play
background music (BGM). It comprises an integrated 120 W mono mixer amplifier, a CD-player that can play
normal audio-CD's as well as long play MP3-encoded CD's and a digitally controlled AM/FM-tuner for accurate
capture of radio stations. Up to three microphones and an auxiliary source signal can be connected to the mixer
amplifier and mixed, with priority or VOX switching available for the main microphone. The output signal can be
switched to two different zones with individual attenuation control. A third zone receives only priority calls and no
music.

Carefully peel off the protective plastic film on both displays. Do not use sharp or pointed objects in order to avoid
scratches. Use your fingernails instead.
The BGM/paging system unit is intended for table-top use. It can also be put on a shelf, provided that there is a free
space of at least 10 cm on both sides of and above the unit to ensure proper ventilation. The unit has a built-in fan
that will switch on when the temperature inside the unit rises. Do not put any other equipment directly on top of this
unit. The ambient temperature should not exceed 45 °C. Mounting of the unit in 19”-racks is not recommended as
often the temperature in these racks will exceed 45 °C.

Microphone 1 has different operating modes:
Priority mode:
Connect the microphone to the DIN-socket at the rear of the unit and enable the priority mode with configuration
switch 1 (set to ON-position). This requires a microphone with a priority switch on contacts 4 and 5 of the 5-pin
DIN-connector, such as the table-top microphone LBB 1950. In this mode, microphone 1 will have priority over
microphones 2 and 3 and the background music. Activating this microphone will mute the other microphones and
the music and will also override zone switching and zone attenuation. Priority announcements will even be heard in
deselected zones. This mode is normally used for important (emergency) announcements. You can select a chime
signal to precede such a priority call with configuration switch 3, a speech filter with configuration switch 4 and
phantom power with configuration switch 5.
VOX mode:
Connect the microphone to the phone jack socket at the front of the unit and enable the VOX mode with
configuration switch 2 (set to ON-position). This mode will attenuate the background music or microphones 2 and 3
to a preset ducking level as long as you speak into the microphone. It is normally used with handheld microphones
like the LBC 2900/15 for making casual announcements, temporarily surpressing the music. Background music and
announcements will be heard in the selected zones. The front connection for microphone 1 does not have phantom
power for electret or condenser microphones, so a dynamic microphone must be used. A chime is not available in
this mode, but you can select the speech filter via configuration switch 4.
When no priority or VOX mode has been selected, microphone 1 will just mix with the background music or the
other microphones to the selected zones.

Connect microphones 2 and 3 to the rear XLR-sockets. Enable phantom power for these microphones with
configuration switches 6 and 7, if you use electret or condenser microphones. These microphones just mix with
the background music.
Connect an auxiliary music source, like a tape/cassette recorder or the audio signal of a DVD player, to the
auxiliary Cinch-sockets on the rear. Stereo signals will be converted to mono.
The tape output sockets may be used for connection to a tape/cassette recorder to record microphone and
background music signals. Both sockets provide the same mono signal.

Loudspeakers are connected via screw terminals, behind a removable plastic cover for safety. This Plena System
Amplifier has a very flexible output configuration, allowing for different groups of loudspeakers.
• Connect 100 V-loudspeakers for zone 1 to the 100 V-/0-terminals of zone 1. The selection button and the output
attenuator for zone 1 (both on the front panel) control this output. If a low impedance loudspeaker is used for
zone 1, connect it to the 8 Ohm- / 0-terminals of zone 1, but now the output level will not be affected by the
attenuator.
• Proceed in the same way for zone 2.
• Connect 100 V-loudspeakers that should receive only priority announcements from microphone 1 to the Call
Only 100 V- /0-terminals. For this, the priority mode must be enabled (see §4.2).
The Call Active terminals provide voltage free relay contacts. This contact is closed as long as a priority call is
active. This contact may be used for overriding remote volume controls or other purposes. It is switched together
with the Call Only loudspeaker zone.
Note
Ensure that the loudspeakers are wired in phase by connecting the 0-terminals of loudspeakers in the same
zone together to the amplifier 0-terminal.
Caution
Connect 100 V-loudspeakers in the same zone just in parallel, but take care that the total power of the
loudspeakers, i.e. the load, does not exceed the 120 W power rating of this Plena unit
Caution
It is not recommended to use both low impedance loudspeakers and 100 V-loudspeakers simultaneously.
Multiple low impedance loudspeakers should be connected in series or parallel so that the total impedance is
more than 8 Ohm.

5.1.1 Source selection
•
•
Use the input volume controls (30, 28, 27 and 25) to balance the sound level of the microphone inputs and the
background music.
Use the music source selection button (26) to select the built-in CD-player/tuner or an auxiliary source. If the
auxiliary source is selected, the CD-player and the tuner are switched off. If the CD-player/tuner is selected, the
CD-player will be active as long as it is playing. If the CD-player stops, the tuner will take over automatically.
5.1.2 Volume and tone control
•
•
Use the master volume control (22) to control the volume of the music/microphone mix.
The bass and treble tone controls (23 and 24) affect the microphones as well as the music.
5.1.3 Zone selection
•
•
Use the output attenuators (20 and 18) to balance the sound level in zones 1 and 2, respectively.
Use the zone selection buttons (21 and 19) to switch a zone on or off. The priority microphone active LED (17)
indicates that a priority call is active. Such a priority call overrides the zone selection and attenuation settings. A
priority call addresses all zones with 0 dB attenuation.
5.2 Operation of tuner
5.2.1 Station selection
•
•
Use the tuner FM/AM selection key (13) to choose between FM and AM reception.
Use the tuner frequency up/down keys (12) to step up or down in frequency. Prolonged pressing makes the tuner
search for the next station.

5.2.2Programming
•
•
Save the selected radio station as a preset by pressing the tuner program key (15).
Press the tuner memory keys M1/6 to M5/10 (10) for memory position 1 to 5.
Or
•
•
Press the tuner program key (15), the tuner shift key (16) and the tuner memory keys M1/6 to M5/10 (10) for
memory position 6 to 10.
The tuner display (11) shows 'MEMORY' during this process. Both for AM and FM, 10 presets are available.
Saved presets are selected by pressing the tuner memory keys M1/6 to M5/10 (10) or by pressing the tuner shift key
(16) followed by M1/6 to M5/10. For easy selection, pressing the tuner scan key (14) monitors the presets by
selecting all 10 presets sequentially for 5 seconds.
5.3 Operation of CD-player
5.3.1 Track selection
Note
After inserting a new CD, the CD-player detects the type of CD and shows it on the CD display (7): 'CD' for
an audio-CD or 'MP3' for a disc containing MP3-files.
Note that loading of MP3-CD's may take longer, depending on the number of tracks and subdirectories, as an
internal table of contents is made. The MP3-files in the root directory and in the subdirectories are all put in
separate folders for easy track selection. The folder number is indicated on the display, followed by the track
number and the time.
For track selection on audio-CD's proceed as follows:
• Shortly press the CD previous key (5) and/or the CD next key (8) to select the track. Prolonged pressing results
in fast reverse or fast forward.
• Use the CD pause/play key (6) to pause or to play (resume playing).
• Use the CD stop/eject key (9) to stop playing (press once) and/or to eject the CD (press twice).
For track selection on MP3-CD's first select the folder that contains the track. Proceed as follows:
• Press the CD MP3 folder selection key (2).
• Press the CD previous key (5) and/or the CD next key (8). The display shows 'FOLDER' during this process.
Pressing the CD MP3 folder selection key once more resumes the track selection mode in the selected folder.

By repeatedly pressing the CD repeat key (4) you select the following modes:
- Playing all tracks (MP3: in all folders) and stop.
- Repeating the current track. The display shows '1'.
- Repeating all MP3-tracks within the current folder. The display shows ' '.
- Repeating all tracks (MP3: in all folders). The display shows '
'.
- Random playing of tracks (MP3: in all folders). The display shows 'RANDOM'.
Plena BGM/Paging System | Installation and Operating Manual |Operation
en | 19
If a MP3-CD is stopped and loaded again, the player will resume playing where it was stopped. In this way it is
avoided that only the first part of a very long MP3-CD is played over and over again each day. If, however, an
audio-CD is stopped and loaded again, it just starts with track 1.
5.3.2Programming
To program a playlist selection:
• Press the CD program key (3).
• Select a track by pressing the CD previous key (5) and/or the CD next key (8). In the case of a MP3-CD folder
selection is possible, as described above.
• Press the CD repeat key (4) to store the first track and step to the next track of the playlist, open for selection.
• Repeat this process until the playlist is finished.
• Finally press the CD pause/play key (6) to start playback of the playlist.
5.4 Creation of MP3 CD-R's
You can make your own MP3 CD-R's (CD-ROM's) on a normal PC with a CD-burner. Numerous programs for this
purpose are available as freeware or shareware. Some websites to download from are: www.mp3.com,
www.download.com, www.shareware.com and www.zdnet.com.
Search there, or in a general search program as www.google.com, for 'CD-ripper'. You can collect your MP3-files in
different subdirectories or folders on your PC and transfer these files to the CD-R. Always use the file name
extension .mp3. Constant MP3-bit rates (CBR) of 32 - 320 kbps are supported, as well as variable bit rate (VBR) files.
Note
As the reflectivity of a CD-RW (CD-Rewritable) is far below that of a CD and a CD-R, playback of CD-RW's
is not guaranteed. On the CD-R the ISO-9660 file system should be used. Do not use the UDF file system.
