Siemens TBM-2 User manual

P/N 315-093782-9
INTRODUCTION
The Model TBM-2 Termination Block module
from Siemens Industry, Inc., is the central
connection point for audio functions in the
MXLV System (See Figure 1). The ACM-1
Audio Control module communicates with
other modules in the system through the
TBM-2. In addition, the TBM-2 has connections
for the recording of telephone and microphone
messages, and the control connections to
activate recording equipment. Refer to the
CSG-M Manual, P/N 315-090381, to select
the Voice Options for your system.
The TBM-2 has two single pole, double throw
(SPDT) dry contacts, AUX CTRL1 and AUX
CTRL2, that control recording equipment.
When the microphone or telephone is active,
the signal goes to the chosen auxiliary output
and the corresponding control output changes
state. The TBM-2 does not include connectors
or cables for connecting the auxiliary outputs
and auxiliary controls.
The TBM-2 has a connection for an external
signal source. Use the AUX IN input and a
VSM-1 function to connect an external signal
source to the MXLV System. See Figure 4 for
information on input signals.
The TBM-2 provides screw terminal blocks
and connectors that interface the internal
wiring and field wiring (See Table 1).
For additional information on the MXL/MXLV
System, refer to the MXL/MXLV Manual, P/N
315-092036.
INSTALLATION
Remove all system power before installation,
first battery and then AC. (To power up, connect
the AC first and then the battery.)
The TBM-2 mounts on the right side of the
backbox next to the MMB or PSR-1, approxi-
mately one-third of the way down from the top
(Refer to Figure 2).
NOTE: In a Remote Extender enclosure the
TBM-2 mounts below the PS-5N7. Refer
to the PS-5N7 Instructions, P/N 315-092729.

WIRING
Refer to Figures 3 and 4.
All wiring must comply with
national and local codes.
For the audio and telephone risers:
Maximum wire size: 14 AWG twisted
pair, shielded
Minimum wire size: 18 AWG twisted
pair, shielded
Maximum loop resistance: 20 ohms for both
wires
Connect the 24 VDC to TB3 using 14 AWG
single conductor wire. Terminal 1 is for +24
VDC; terminal 2 is for 24 VDC return.
Refer to the CSG-M configuration printout to
determine the wiring style (either Style Y or
Style Z) for terminal block TB5.
For Style Z wiring, make the following connec-
tions:
• Connect terminals 1 and 4 in one cable going
out to Riser 1.
• Connect terminals 2 and 3 in another cable
coming back from the last destination of
Riser 1.
• The other audio risers connect in a similar
fashion.
For Style Y connections, use only one cable.
Refer to Figure 3 for details.

Mounting the TBM-2
NOTE:
In a Remote Extender
enclosure, a PS-5N7 is
mounted above the TBM-2.
1. Before installing the module, mount the
PCB assembly to the mounting bracket
supplied using the four No. 6 screws
provided.
2. Place the TBM-2 assembly face up on the
three threaded studs arranged in a triangle
with TB5, the 15 position terminal block at
the top.
3. Secure the TBM-2 with the three No. 10
nuts provided.

3
Connect the riser cables to TB5 in the desired style,
using 18-14 AWG twisted, shielded pair. The other
ends of the risers connect to the OCC-1 terminal
block. Refer to the OCC-1 Installation Instructions,
P/N 315-090918, for further details.
For connections to other connectors and terminal
blocks, refer to the appropriate module installa-
tion instructions. (See also Figure 3 or Figure 4,
as appropriate.)
CAUTION: Keep the riser cables away from the AC power lines, the 24 VDC
supply lines, and the wires carrying the amplified audio signals.
