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.
