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

Plena Message Manager | Installation and Operating Manual | About the equipment
en | 8
The Plena Message Manager functions as an audio source in the overall Plena PA-system. With this unit it is
possible to play, via other Plena units, pre-recorded messages that are triggered from external sources or the unit's
front panel switches.
These pre-recorded messages (that can be made on a PC in .wav-format) can be used for various purposes, e.g.
routine messages or emergency calls. The messages are stored in solid state memories (Eeproms) and are
continuously supervised on availability.
When the message manager is connected to the Plena System Pre-amplifier (LBB1925), it is also possible to
distribute the messages in pre-programmed zones.
The unit is delivered with the mains voltage selector set to 230 Vac. This selector can be set to 115 Vac.
The unit is not provided with a separate power ON indication. One message LED on the front panel will always be
lit (thus functioning as a power ON indication) as at least one message will be loaded. In case no messages are
loaded, this fault situation is indicated by the fault LED.
1.1 Features
-
Up to 12 different messages can be stored.
Up to 12 message sequences or announcements (each consisting of up to 4 different messages + zone information) can be stored.
Messages can be edited, assembled and uploaded by means of a PC.
The message content is continuously supervised on availability.
The cabling of trigger inputs 1 through 6 can be supervised on cuts and short-circuits.
Mains supply voltage (230/115 Vac) can be supervised.
Pilot tone can be added to supervise the audio connection to an amplifier or the sound system.
Internal pilot tone to supervise the internal audio path.
Support for various sample frequencies to balance audio quality versus message length
1.2 Capacity
The storage device of the messages is a built-in block-erasable EEPROM with fixed storage capacity of 8.38 MByte.
The message manager accepts .wav-files with sample frequencies of 24, 22.050, 16, 12, 11.025 and 8 kHz. The word
length is fixed to 16 bits. This means that the distortion and signal to noise level is of CD quality. Lower sample
frequencies mean a decrease in audio quality (lower bandwidth), but an increase in message length. See the table
below.

The message manager can be used with all Plena amplifiers via the Cinch output (4) or the XLR Output (6). The
level of the messages can be set via the message volume control (2).
To fully benefit from the features of the message manager in the overall Plena system (e.g. to distribute pre-recorded
messages to pre-programmed zones) the unit must be connected via the system pre-amplifier LBB1925. To do this,
use the RS232 cable and the audio cable supplied.
There are several ways to connect the message manager to the system pre-amplifier:
- Connecting the Cinch output (4) of the message manager to the Cinch PC Audio In (R) line input of the system pre-amplifier, as shown in figure 3.2 (in which the LBB1961 functions as a BGM source).
- Connecting the XLR output (6) of the message manager to the points 1 and 3 of the 8-pole DIN socket of the
system pre-amplifier.

It is possible to connect the LBB1965 message manager between a mixer pre-amplifier and a power amplifier.
When the message manager is not active, the mixer pre-amplifier is routed to the power amplifier. However, when
the message manager becomes active, this loopthrough connection is interrupted and the message manager is
switched to the power amplifier.
Figure 3.3 shows this configuration example in which the Plena Mixer Pre-amplifier LBB1920 is used with a Plena
Power Amplifier LBB1938. This is a high priority application, as the message manager has absolute priority.

Figure 3.4
Message sequences or announcements are started with make contacts (17). These make contacts are connected to
the trigger input screw terminals (11). The cabling of the first six trigger input contacts (1 through 6) can have
supervision by means of a window comparator. Normal operation of these inputs requires two series connected
resistors of 10 kOhm and 3.3 kOhm, permanently connected to the far end of the cable connected to each trigger
input. Triggering occurs by short-circuiting the 10 kOhm resistor as shown in figure 3.4.
Open or short-circuited cables to such an input result in a fault situation that is detected by the window comparator.
The fault indicator LED at the front will light up and the internal fault relay will be unpowered which gives a
contact change on the screw terminals (10) at the rear.
Via the dipswitches 1 through 6 at the rear of the unit supervision of each individual trigger input (1 - 6) can be
enabled ('ON') or disabled ('OFF'). When disabled these inputs act the same as inputs 7 through 12.
Via dipswitch # 7 it is possible to enable mains failure checking. When enabled ('ON') the fault indicator LED at the
front will light up and the internal fault relay will go to the unpowered state upon mains failure, although the unit
may continue to work on the 24 Vdc battery.
When disabled ('OFF') switching between mains and battery operation is automatic and will not be noticed.
Via dipswitch # 8 it is possible to switch ON a 20 kHz pilot tone to the output signal for supervision of the cable by
connecting equipment. The level of the pilot tone is adjustable (from 'OFF' to -14dB with respect to maximum audio
level) via the pilot tone volume control (1). The default volume level is -20 dB.

Figure 4.1
To upload the messages and to configure the sequence of the messages, a PC must be used that meets the following
minimum requirements:
- Pentium processor with a clock frequency of 100 MHz or higher
- Operating system: Windows 95® or higher
- CD-ROM drive
To prepare and to record the messages the standard available Windows® operating system can be used, but it is
also possible to purchase the messages from a studio. All messages must be stored as .wav files in the PC. Only
mono .wav files with sample frequencies of 24, 22.050, 16, 12, 11.025 and 8 kHz and a word length of 16 bits can be
used. The sample frequency for each separate message can be different. See §1.2.
To create messages or message sequences use the software on the CD-ROM supplied with the unit. To install this
software proceed as follows:
• Close all applications that are open.
• Insert the CD-ROM into the CD-ROM drive.
• In case the Setup-program does not start up automatically, go to the next step. Otherwise follow the instructions
on the screen.
• Choose Run from the Start-menu.
• Type 'd:\setup' (where 'd' is the CD-ROM drive).
• Click OK or press Enter.
• Follow the instructions on the screen.
Upon installation proceed as follows:
• Start the program. A screen similar to the following screen will appear.
Figure 4.2

In the left hand part of the screen the messages (max. 12) can be filled out. Proceed as follows:
• Put the cursor in the File box of message # 1.
• Type the message file name and location (or use the Browse box to go to the folder where the message is
stored).
• Proceed in the same way for all necessary messages. The Time, Size and Sample (sample rate) fields will automatically be filled out. During this process the program software will monitor the required memory capacity
and the overall capacity that is available.
In the right hand part of the screen the sequence of the messages can be determined per trigger input. Proceed as
follows:
• Click on the first [▼]-box to invoke a pull-down menu that contains all message numbers that have been filled
out before.
• Select one of the messages.
• Select the next message, using the box to the right hand side of the first [▼]-box,. In this way up to four messages can be selected, thus creating a programmed message sequence. The total time (in s) for this message
sequence will be displayed in the Time field.
• If required click on the appropriate Zone number boxes in order to activate the corresponding zone(s). This
option is only of interest when the message manager is connected to a system pre-amplifier LBB1925.
• Proceed in the same way for the other message sequences.
• By clicking on the Play boxes in both the (left hand) Message screen and the (right hand) Trigger screen, the programmed messages or message sequences will be audible over the PC's loudspeakers. Click again to stop this
action.
The menu bar at the top of the screen provides access to the File menu, the Setup menu and the Help menu.
Upon selection of File a pull-down menu appears with the following options:
- Open: Opens the dialog box to select a configuration file
- Save: Saves the configuration file; it is recommended to create a separate folder for this purpose
- Save as: Opens the dialog box to save the current configuration file
- Save as text file: Opens Notepad for saving the configuration file as a .txt file or for printing; it is recommended
to select font type Arial for optimum alignment
- Exit: Closes the program
Upon selection of Setup a pull-down menu appears with the options to:
- Select the RS232 Com port on the PC
- Select the language on the screen
Upon selection of Help you can select About Plena message manager to display the program release number.
•
•
•
Connect the supplied RS232 cable between the PC and the message manager. Use the RS232 female socket at
the rear of the unit.
Use the Com port selection button (in the pull-down menu under the Setup box) to select Com port 1 or 2 of the
PC.
Click the Send messages and configuration button to transfer the file to the message manager. During this file transfer
-which, depending on the file size of the messages, may take up to 45 minutes (at 115 kbps)- the percentage ready
bar on the screen indicates the progress of the uploading process. During uploading the program mode indicator
LED (5) on the front is lit.The message indicator LEDs (7) on the front of the unit will be continuously lit for
each message that is present and available in the message manager.
Bosch Security Systems | 2003-09 | 9922 141 50502en

The status bar at the bottom of the screen contains three fields:
- The STATUS field shows the progress of the uploading process.
- The RS232 PORT shows the RS232 data during uploading.
- The rightmost box of the status bar shows the actual upload time.
On the supplied CD-ROM you can find a copy of the program R8brain (r8brain.exe, available as freeware at
www.voxenga.com).
With the help of this program the sample rate of the .wav files can be changed, if required. It is recommended to use
the lowest sample rate that does not degrade the audio quality.
Proceed as follows:
• Start the program r8brain.exe.
• Browse to the .wav file that must be modified.
• Browse to the folder in which the modified file must be placed.
• If required, change the message file name in the Browse menu.
• Enter the output sample rate in the appropriate field or click on the output sample rate in the pull-down menu
(sample rates like 12 kHz are not in the list, but can be entered from the keyboard).
• Select 16-bit for Output bit depth and High or Very High for Conversion quality.
• Click on Perform r8brain. A progress bar shows the progress of the conversion.
• To convert from stereo .wav files to mono use the program Sound Recorder that comes with Windows®.
Generally, you can find this program via Start > Programs > Accessories > Entertainment > Sound Recorder.
4.2 Play-back messages
When an announcement is started via a trigger contact, the corresponding trigger indicator LED (8) will light up.
Single-shot triggering and repeating mode is provided. After pressing a trigger switch the announcement is played
completely. If the trigger switch is still ON upon completion of the announcement, this announcement will be
repeated until the trigger switch is released. Then it will complete the running announcement and stop.
Within an announcement there is no possibility for repetition loops of individual messages. However the same
message may be programmed in the sequence more than once (max. 4).
Trigger inputs have serial priority, i.e. input 1 has priority over trigger input 2, 2 over 3, etc.
When an announcement is overridden with an announcement with a higher priority, the first indicator LED will
extinguish and the new LED will light up. Lower priority triggers will be ignored.
The LED of the running message is flashing (2 Hz). If the current announcement is interrupted via RS232 by a
higher priority call from the connected system pre-amplifier, the LED will stop flashing and light up continuously.
The front panel of the unit contains six pushbuttons (9) to activate announcements 7 to 12, effectively in parallel
with the trigger inputs 7 to 12.
If the unit is connected to the LBB1925 via RS232, trigger inputs 1 through 6 will be processed with a priority equal
to the high-priority setting of a connected LBB1946 call station. Trigger inputs 7 through 12 are processed with a
priority equal to the low-priority setting of a connected LBB1946 call station.
This priority level affects only the priority of the announcements compared to other sources connected to the system
pre-amplifier, e.g. call stations. It does not affect the priority between the trigger inputs of the message manager,
which is serial.
If a repeating announcement is interrupted by a higher priority call via the system pre-amplifier LBB1925 or by a
higher priority trigger input (lower contact number) and if, after the interruption, the original trigger input is still
Bosch Security Systems | 2003-09 | 9922 141 50502en
Plena Message Manager | Installation and Operating Manual | Operation
en | 20
active, this announcement will start again from the beginning. Non-repeating single-shot announcements are just
cancelled without finishing.
4.3 Monitoring
The message manager comprises a 6.3 mm headphone output socket (2) with a momentary monitor pushbutton (3).
When the unit is not active it is possible to select messages for monitoring. Note that memory supervision
(checksum) is disabled during monitoring.
If during monitoring any trigger input contact for starting an announcement is made, the monitoring process is
cancelled immediately and the normal play-back mode is resumed.
To select messages for monitoring simply press the momentary monitor pushbutton. A single push starts message
#1. If the pushbutton remains pressed, message #2 will be played automatically upon completion of message #1, #3
after #2, etc., up to and including the last available message. Then it stops.
If during play-back of a message the monitor pushbutton is repeatedly pressed, the next message is started without
finishing the previous one. During this monitoring process the corresponding message indicator LEDs are flashing.
Running messages, triggered manually or started via the trigger contacts, can be heard on the monitor headphone as
well. There is no monitor volume control.
4.4 Supervision
In conformity with the major standards for emergency sound systems like IEC 60849, the following features of the
message manager are or can be supervised:
- Content of the message memory. The micro controller adds a checksum to the messages. This supervision
requires no user intervention. If no messages are played the processor will read out the complete audio memory to compare its content to the checksum, automatically and continuously within a 100 s cycle.
- Availability of any message in the audio memory.
- Presence of mains supply.
- Trigger contacts and involved wiring of trigger inputs 1 to 6 (see also §1.4).
- Resetting of the internal processors by the 'watchdog' circuitry. The processors have a watchdog circuit to
reset the processor if the normal program flow is halted or deviated from.
- Supervision of the DAC using a 1 Hz pilot tone.
- Supervision of audio connections using a 20 kHz pilot tone.
If during supervision a fault is pointed out, the fault indicator LED (6) will light up and the internal fault relay, which
is normally activated when the power supply is connected and the unit is ON, will be switched to its unpowered
state.
Potential free fault contacts (SPDT) and potential free message active relay contacts are provided at the rear of the
unit.
4.5 Manual editing of messages
The program mode pushbutton (4) can be used to manually change the message sequence of trigger inputs 7 to 12
and the corresponding zone set-up. Manual editing is not possible for the trigger inputs 1 to 6; these input
configurations must be uploaded from the PC to avoid abuse.
Manual editing of trigger inputs is done as follows:
• Press the program mode pushbutton (4) and keep it depressed for more than 3 s. The program mode indicator
LED (5) will light up to indicate that the message manager is in the program mode.

Briefly press one of the pushbuttons (9), e.g. #11. The corresponding trigger indicator LED (8) will flash and the
(upper) trigger indicator LEDs 1 to 6 will indicate the stored zones for pushbutton #11. The message indicator
LEDs (7) will only indicate the messages related to pushbutton #11. Their place in the sequence is not indicated.
Use the pushbuttons (9) to toggle the zones 1 to 6 ON and OFF, thus indicating the new zone selection.
Press the monitor pushbutton (3) briefly to clear the present message sequence for the selected pushbutton (9).
Pressing the monitor pushbutton (3) once more causes the message indicator LED #1 to flash; subsequent pressing causes the message indicator LEDs #2, 3, 4, etc. to flash. If the monitor pushbutton is pressed for more than
3 s the message indicator LED that flashed is selected as the first message of a new sequence for the selected
pushbutton (9). In this way up to four messages can be selected in a random order to be part of that announcement. After the fourth message no more messages will be accepted.
Press the program mode pushbutton (4) once again for more than 3 s to enter the new configuration data and to
exit the program mode.
Repeat the above procedure for any of the other pushbuttons (9).
If during this manual editing process a trigger input is activated, the unit will quit the program mode and the
requested announcement will be started.
If in the program mode no pushbutton is pressed for approx. 25 s, the unit will automatically resume its normal
working mode, without storing the new configuration data.
