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.
