Eng 1. INTRODUCTION
The Recordable Message Module (RMM) is for use in the SM 25B Booster Frames or Module
Extension Frame (MXF). It is a digital recorder for recording, monitoring and playing back up to
10 messages with a total playing time of 132 seconds. Up to three additional memory modules
(MSM6685AJS from OKI Semiconductor, contact Philips CSI Sales Support for availability) can
be added to the RMM printed circuit board to increase the total playing time to 528 seconds.
Messages are backed up using four NiCd batteries. Messages are recorded using the GMM/MIX
module or CS-B via the SM 25B system bus. Messages can be remotely activated via the
input/output connector on the rear panel. A block diagram is shown in fig. 1.1.
Note: The RMM internal batteries should be replaced after five years. The batteries should be dis-
connected using jumper PC25 (figure 1.13) if the RMM is not to be used for more than six months.
The RMM is delivered with the batteries disconnected. Refer to section 2.2 for information about con-
necting the batteries for the first time.
Note: Refer also to the Installation Instructions and User Instructions for the Booster Frames, MXF,
GMM, MIX, CS-B, CX-B and CSM.

RMM modes
The RMM can operate in three modes:
• Record - for recording messages
• Play - for playing back pre-recorded messages
• Monitor - for listening to messages via headphones connected to the front panel
Note: The default mode is play. If the RMM is in any other mode, and is not recording or monitoring,
it will revert to play after two minutes if no actions are initiated by the user.
Message inputs
Messages can be recorded using a GMM/MIX or CS-B/CX-B that is connected to the SM 25B
system. The GMM/MIX can receive microphone inputs or line inputs (for example, from a CD
player). In this case, configuration settings in the GMM such as speech filters, compression,
priority and chime apply to any messages recorded. Messages recorded using a GMM are routed
to the RMM via the SM 25B system flat-cable connector. In the case of messages recorded using
a CS-B, configuration settings such as zone setting, priority and chimes apply to any messages
recorded. Messages recorded using a CS-B are routed to the RMM via a CSM module and the
SM 25B system flat-cable connector.
Note: Messages recorded using the CS-B contain zoning information that is passed to the RMM.
However, messages recorded using the GMM/MIX are sent to all zones by default. In this case,
zoning information can be specified using the RMM DIL switches.

Eng
Configurable functionality
The RMM can be configured using DIL switches and potentiometers on the PCB. The
following can be configured:
• Priority for each message recorded (from priority 1 to priority 5)
• Zone selection for each message recorded (any combination of 12 zones)
• External indication of message playing for each message input
• Message activation/deactivation properties for each message input
• Overall audio output level and headphone volume level
2. INSTALLATION, CONNECTION AND CONFIGURATION
2.1 Installing the RMM
Installing the RMM in a Booster Frame
WARNING: SWITCH THE EQUIPMENT OFF AND REMOVE THE MAINS PLUG
FROM THE MAINS OUTLET BEFORE OPENING THE EQUIPMENT.
Caution: The RMM is designed to operate safely in a SM 25B Booster Frame or MXF.
Ensure that the Booster Frame or MXF is installed in accordance with the Installation
Instructions supplied with the equipment before installing the RMM.
Supplied with the RMM (LBB 2541/10):
• Installation and User Instructions
Special tools required:
• T10 Torx screwdriver
• T20 Torx screwdriver (for 19-inch rack mounting)
Installation procedure
1. If the RMM is to be mounted in a Booster Frame in a 19-inch rack:
- Switch off and unplug the Booster Frame from the mains (fig. 1.4).
- Loosen the four captive Torx screws 'A' (fig. 1.5).
- Slide the Booster Frame forward until it stops and lift out the cardboard top cover (fig. 1.6).
Note: All positions in the Booster Frame are functionally identical. The RMM may be mounted in any
available position.
Note: At this point, all switches on the PCB are accessible. If the RMM is to be configured, refer to
section 2.3.
2. Insert the RMM and push it completely home (fig. 1.7).
3. Tighten the captive Torx screw on top of the front panel (fig. 1.8, detail A).
4. The SM 25B Booster Frame is connected to the RMM via a flexible 16-pole system cable.
This flat-cable runs from the Booster Frame PCB along the top of the Booster Frame
(fig. 1.9 detail B)
Caution: Unused module positions in the Booster Frame must be covered with a
blanking panel to ensure that the forced air cooling functions correctly (fig. 1.10).
5. Replace the cardboard top cover and slide the Booster Frame back into the 19-inch rack
(or Table-top Housing) and tighten the four Torx screws (fig. 1.11).
Caution: The cardboard top cover must be replaced before sliding the Booster Frame
back into the rack to ensure that the forced air cooling functions correctly.

10
2.2 Connecting the RMM
Caution: When wiring inputs to the RMM in a 19-inch rack, ensure that the cables are
of sufficient length to allow the Booster Frame to be withdrawn on its runners (approx.
30 cm, 12 in.).
Connecting RMM inputs/outputs
Inputs from the GMM/MIX or CS-B are connected via the SM 25B system bus. This connection is
made using the 16-pole flat-cable that runs along the top of the Booster Frame or MXF. Each mes-
sage can be remotely activated via the 15-pole connector on the rear panel. This connector has
separate screw fastenings for remote connections, that are labelled for each message (0 to 9).
Galvanically isolated relay contacts are available on the rear panel of the RMM. This relay is acti-
vated during message playback if the message running contact is enabled (refer to figure 1.12).
This can be enabled or disabled for each message using the RMM DIL switches.
Connecting the RMM internal batteries
Before the RMM can be used for the first time, the internal batteries must be connected using
jumper PC25 (figure 1.13). The internal memory of the RMM must now be cleared. To do so:
• Switch the SM 25B system off and on again while pressing the mode button on the front
panel of the RMM.
All the messages will now be empty, and a ‘-’ will flash to indicate this.
2.3 Configuring the RMM

Eng
Note: Changes in configuration settings for each message only take place after pressing the
‘UPDATE’ button (S8, figure 1.13) while the RMM is in record mode. The display will show a ‘U’
when the ‘UPDATE’ button is pressed.
Priority selection for messages
Each message recorded can be assigned a priority from 1 (lowest) to 5 (highest). The priority
settings on the GMM/MIX or CS-B are passed to the RMM via the SM 25B system bus. How-
ever, these settings can be altered on the RMM as follows:
• Select the message using the message select push button in monitor mode
• Set the corresponding switches on DIL switch S2 to ‘ON’
Zone selection for messages
Each message recorded using the GMM/MIX can be routed to any combination of 12
separate, selectable zones. If a message is routed to all zones, this is called an ‘all call’.
Note: Manual zone switching via the MZS provides no zone information to the RMM.
Note: Messages recorded using the CS-B/CX-B already contain zoning information. However, this
information can be changed on the RMM as described below.
To select zones for messages:
• Select the message using the message select push button in monitor mode
• Set the corresponding switches on DIL switch S3 and S4 to 'ON'
The default zone selection setting for each message is ‘all call’ for recordings via the
GMM/MIX module. Recordings via the CS-B contain the corresponding zone information of
the CS-B.
Enabling the external message playing indication
It is possible to activate a setting that enables the ‘Message active contact’ to be triggered
when a remotely activated message is being played. To do so:
• Set switch 7 on DIL switch S4 to 'ON'
Note: Messages are always indicated on the RMM front panel display when they are being played by
the message number flashing on and off. If the ‘Message active contact’ is enabled, the message
number has a full stop (‘.’) beside it.
Message activation/deactivation properties
It is necessary to select whether the messages are activated by a pulse or ON/OFF input. A
pulse input activates the message. The message will run until it ends regardless of the length
of the pulse. In the case of ON/OFF, an ON input activates the message, which lasts, and
repeats, until the input goes to OFF.
To select Pulse or ON/OFF:
• Set switch 7 on DIL switch S3 to 'ON' for pulse, 'OFF' for ON/OFF
The default setting is pulse.
It is necessary to select whether the RMM is activated by closing external switching contacts
which are normally open, or by opening external switching contacts which are normally
closed. This setting will depend on how the input is presented to the RMM. To select
normally open or normally closed:
• Set switch 8 on DIL switch S3 to ‘ON’ for normally open, ‘OFF’ for normally closed
It is necessary to select how the RMM responds when a higher priority message (if present),
microphone or call station overrides a message that is currently playing. Deactivation means
that the first message is skipped. Interruption means the first message restarts when the high-
er priority input ends. To select interruption or deactivation:
• Set switch 4 on DIL switch S4 to 'ON' for deactivation, 'OFF' for interruption
The default setting is ‘interruption’.

12
Eng Audio gain level and headphone gain level
The audio gain level and headphone gain level can be adjusted using potentiometers on the
RMM printed circuit board. To set the gain levels:
• Adjust potentiometers P1 (audio gain level) and P2 (headphone gain level).
3. OPERATING THE RMM
It is possible to carry out the following operations using the RMM:
• Record a new message
• Delete a message
• Play a message
• Monitor a message
• Monitor the status of the RMM
These operations are described below.
3.1 Recording a new message
Recording a message using the GMM/MIX
To record a message using the GMM/MIX:
1. Ensure that the microphone/line input is connected properly to one of the GMM/MIX rear
connectors.
Note: Microphones can be either condenser types (with phantom power supply) or dynamic types.
For messages without chime tone or priority, a microphone with a 3-pole connector can be used with
the GMM/MIX set to mix mode. In this case, message recording can only be started and stopped
using controls on the front panel of the RMM. Otherwise a microphone with a male 5-pole DIN
connector (with remote switching contacts) should be used with the GMM/MIX set to mix-on-demand
or priority mode. Two Philips microphones are available (LBB 9521/10 and LBB 9518/10) with a ded-
icated LED indicator and switch to show system status. Any messages recorded using the GMM/MIX
will be distributed to the SM 25B system bus, and will therefore be distributed to the selected zones
while recording is taking place. It may therefore be necessary to make such recordings when the pub-
lic address venue is not being used, or with the speaker outputs disconnected.
2. Ensure that the configuration settings for the GMM/MIX, for example priority settings,
chime tone and speech filter, are correctly made. For more information, refer to the
relevant Instructions For Use and Installation Instructions.
3. Press the mode selector push button (item 6) until the yellow indicator LED (item 4) is on
(monitor mode).
4. Press the message select push button (item 8) until the required message number is
displayed on the message indicator (item 5).
Note: A total of 10 messages can be recorded (numbered 0 to 9). Continually pressing the message
select push button will toggle through all 10 messages. Any message number that is empty i.e. has no
recorded message will flash alternately with a ‘-’ symbol.
5. Press the mode selector push button (item 6) until the red mode indicator LED (item 3)
is on (record mode).
Note: If, upon entering the record mode, the message number changes to a continuous ‘-’ symbol,
this indicates that no more memory space is left to record another message. One or more of the exist-
ing messages should first be deleted to clear some memory.
6. Press the start/stop button (item 7) to start recording, if a microphone without remote
switching contacts is being used. Otherwise, activating the microphone switch will start
and stop the recording.

13
Eng
Note: The red mode indicator LED (item 3) will flash while a message is being recorded.
7. When the message is complete, stop the recording using the start/stop button (item 7) or
the microphone switch. The red mode indication LED will stop flashing (but remains on).
Note: If the memory for the message being recorded becomes full, the RMM automatically stops
recording, and the red mode indicator LED stops flashing (but remains on).
Recording a message using the CS-B/CX-B
To record a message using the CS-B:
1. Ensure that the configuration settings for the CS-B/CX-B and CSM, for example priority
settings and chime tone are correctly made. For more information, refer to the relevant
Instructions for use and Installation Instructions.
Note: It is not possible to make a recording using the CS-B unless zone selection is carried out. If no
zones have been selected, the CS-B will generate an error message. Any messages recorded using the
CS-B will be distributed to the SM 25B system bus via the CSM, and will therefore be distributed to
the selected zones while recording is taking place. It may therefore be necessary to make such record-
ings when the public address venue is not being used, or with the speaker outputs disconnected.
2. Press the mode selector push button (item 6) until the yellow indicator LED (item 4) is on
(monitor mode).
3. Press the message select push button (item 8) until the required message number is dis-
played on the message indicator (item 5).
Note: A total of 10 message can be recorded (numbered 0 to 9). Continually pressing the message
select push button will toggle through all 10 messages. Any message number that is empty i.e. has no
recorded message will flash alternately with a ‘-’ symbol.
4. Make the required zone selection settings using the CX-B.
5. Press and hold the PTT button to start recording.
Note: The red mode indicator LED (item 3) on the RMM will flash while a message is being recorded.
6. Record the message.
7. When the message is complete, release the PTT button to stop the recording. The red
mode indication LED (item 3) will stop flashing (but remains on).
3.2 Deleting a message
To delete a message:
1. Press the mode selector push button (item 6) until the yellow indicator LED (item 4) is on
(monitor mode).
2. Press the message select push button (item 8) until the required message number is
displayed on the message indicator (item 5).
3. Press the mode selector push button (item 6) until the red indicator LED (item 3) is on
(record mode).
4. Press and hold the mode selector push button for at least 2 seconds. The message
number on the pre-selected message indicator will flash.
5. Press the start/stop button (item 7) to delete the message.
Note: If the mode selector push button is pressed instead of start/stop, the delete is cancelled.

Eng Note: If a message is empty, the message number flashes alternately with a ‘-’ symbol.
3.3 Playing back a message
Playing a message remotely
To play back a message remotely:
1. Ensure that the remote connections for the required message(s) is made on the connec-
tor (item 1, figure 1.3) on the rear panel of the RMM. A connection is available for each
message, as well as two common connectors (see figure 1.12).
2. A message can now be played back by activating the remote switch.
Note: While a message is being played, the green indicator LED (item 2) flashes (playing mode).
Once the message stops, the indicator stops flashing (but remains on). A full stop (.) beside the mes-
sage number indicates that the ‘Message active contact’ is enabled.
Note: If the remote message contact on the rear panel is activated, and the message activation set-
ting is set to ON/OFF (switch 7 on DIL switch S3), the selected message will continually repeat until
the remote message contact is deactivated.
3.4 Monitoring recorded messages using a headphone
To monitor a recorded message using a headphone:
1. Connect a headphone to the 3.5 mm headphone jack socket (item 9).
2. Press the mode selector push button (item 6) until the yellow selector indicator LED
(item 4) is on (monitor mode).
2. Press the message selector push button (item 8) until the required message number is
displayed on message indicator (item 5).
3. Press the start/stop button (item 7).
4. The selected message plays to the headphone output only (not to selected zones via the
SM 25B system bus).
The volume of the headphones may be changed using P2.
3.5 Monitoring the status of the RMM
The following table gives an overview and explanation of the LED indications on the front
panel of the RMM.
State Mode indication LED Message display
Playback mode Green continuous Last selected message number*
Playing Green flashing Message number
Record mode Red continuous Last selected message number
Recording Red flashing Message number
Monitor mode Yellow continuous Last selected message number
Monitoring Yellow flashing Message number
*Note: If the ‘Message run contact’ is activated for playback, a full stop (.) will appear beside the
message number.
Note: The message select button is only enabled in monitor mode. This helps to avoid accidental
recordings being made.

3.6 Trouble-shooting the RMM
To trouble-shoot the RMM, it is recommended that the following points be investigated:
• If the audio gain level or headphone gain level is too high or low, adjust the gain level using
gain controls P1 and P2.
• Ensure that the connections at the back of the RMM have been properly made.
• Ensure that the connections and configuration of any units used with the RMM (e.g. GMM,
MIX, CS-B, CSM or microphones) are correct.
• Ensure that the settings on the DIL switches (e.g. zone assignment or message
activation/deactivation properties) of the RMM are correct.
