must be used for transient protection (UL 1459).
Refer to LLM-1 Installation Instructions, P/N 315-
093530.
Modes of Operation
The RCM-1 can operate in the following modes:
Local Mode The audio from the local MXL
(ACM) will be switched to local
speaker zones (OCCs). The
global audio riser will be
switched to Port C, the Style 4
output riser.
Global Mode 1 The audio output from the local
MXL is disconnected. The
audio from the global riser is
connected to the local speaker
zones and to Port C, the Style
4 output riser.
Global Mode 2 The audio from the local
system is connected to both
the local speaker outputs and
the global risers.
For additional information on the MXL/MXLV
System, refer to the MXL/MXLV Manual, P/N
315-092036.
Diagnostic LEDs
The RCM-1 has two yellow diagnostic LEDs and
six green diagnostic LEDs along its top edge.
Their functions are described in Table 1 (Refer to
Figure 2 for their location).
PORT STYLE FUNCTION
A6 Audio signal input
B4/7 Audio signal input/output
C4 Audio signal output
D6 Audio signal output
The RCM-1 supervises Port B for open and
short circuits, reports by exception to the MXL,
and isolates the fault.
INTRODUCTION
The Model RCM-1 Riser Control module from
Siemens Building Technologies, Inc.provides
control and supervision of global paging risers
in MXL voice networks. The RCM-1 is a double-
width card and has 4 ports (See Figure 1) with
the following inputs and outputs:
Figure 1
RCM-1 Ports
A D and B C
B C and D
A B, C and D
Only one RCM-1 may be connected to the
MXL. The module communicates with the MXL
using the RS-485 MNET. If the RCM-1 detects
that supervision is lost with the MXL, it will
automatically switch to Local Mode.
If any copper wire pair leaves the building

Description of the RCM-1 Terminals
The RCM-1 can be connected in many different ways. Table 2 describes the various applications. The
block diagrams below show the possible configurations.
Note:
Polarity must be observed
with all riser connections.
Odd pins are hi side while
even pins are lo side. See
the separate wiring
connections for the ACM/
TBM and the OCC shown
in Figure 12.

INSTALLATION
Remove all system power before
installation, first battery and then AC.
(To power up, connect the
AC first, then the battery.)
The RCM-1 has two configuration dipswitches,
S1 and S2. Set the dipswitches before install-
ing the RCM-1 into the OMM-1/2. (See NOTE
following Table 4 for the operation of
dipswitches.)
The RCM-1 takes up one of the 255 possible
network addresses. Use switch S1 to set the
MXL network address. Set this switch according
to the address where the RCM-1 is installed in
the MXL’s network map. Refer to the AccuLINK
(CSG-M) configuration printout for the address of
the module. See Table 3 for settings.
In addition to S1 which is used to set the network
address, the RCM-1 has a second bank of
dipswitches, S2, which must be correctly config-
ured for the RCM-1 to operate properly. Refer to
Table 4 for a description of the functions for each
of the switches in S2.

To close a dipswitch, press down on the side of the dipswitch opposite the side marked OPEN.
To open a slide switch, push the slide to the side opposite the side marked ON.
To close a slide switch, push the slide to the side marked ON.
Use switch S2 to set the correct module configu-
ration for the application you have selected. Refer
to Table 4 and Application Diagrams 1-8 to
determine the setting for your application.
After setting the switches, install the RCM-1 into
the OMM card cage according to the following
instructions. Make sure that the module is in the
card guides and the card edge is firmly seated in
the connectors on the OMM.
CAUTION
At all times handle all plug-in cards with
extreme care. When inserting or removing a
card, be sure the position of the card is kept
at right angles to the OMM board. Other-
wise, the plug-in card can damage or
displace other components.

RCM-1
OMM-1
or
OMM-2
The RCM-1 mounts in the OMM-1 or OMM-2
inside the MXL cabinet. Note that the RCM-1 is a
double-width card that requires the removal of the
middle card guides on the OMM-1 and OMM-2
before the card can be installed. On early ver-
sions of the OMM-1 and OMM-2 this was not
possible. Make sure that the OMM-1 and OMM-2
assemblies have date codes later than 3/1/95.
If the OMM-1 or OMM-2 is already installed in
the MXL, follow these steps:
1. Unfasten the screws that secure the
OMM-1/2 and remove it from the MXL
cabinet.
2. Remove the screws on the rear of the
OMM-1/2 which secure the two middle card
guides and remove the guides.
3. Re-install the OMM-1/2 into the MXL
backbox.
4. Install the RCM-1 into the OMM-1/2.
CAUTION
INSERT THE RCM-1 MODULE IN THE
OMM-1/2 WITH THE ELECTRONIC
COMPONENTS FACING OUTWARD
TOWARDS THE OMM SCREW TERMINALS.
INSTALLATION IN ANY OTHER WAY WILL
CAUSE DAMAGE TO THE RCM-1.
Typical Style 4 Connections - Application 1
(See Figure 4)
This is the basic configuration of the RCM-1. It
allows multiple networked MXL voice systems to
be connected together to act as one large
integrated voice evacuation system.
Figure 4
Typical Style 4 Connections
Notes:
1. Use 18AWG minimum wire.
2. Limit the maximum resistance of loop total from the first RCM to
the last RCM to 100 ohms. Maximum line capacitance = 1µF.
3. The wiring is power limited to NFPA 70 per NEC 760.
4. Maximum voltage is 1.5V RMS.
5. Maximum current is 50mA.
6. Refer to Figure 12 for proper EOLR placement.
7. Refer to Wiring Specification for MXL, MXL-IQ and MXLV
Systems, P/N 315-092772 revision 6 or higher, for additional
wiring information.
8. Positive and negative ground fault detected at <50K ohms for

The RCM-1 provides a Style 4 output which
can be used to connect to other systems which
require global paging capability. A Style 4
output only (PORT C) extension is also
supported.

1. Use 18AWG minimum wire.
2. Limit the maximum resistance of loop total from the first RCM to
the last RCM to 100 ohms. Maximum line capacitance = 1µF.
