INTRODUCTION
The Model ACM-1 Audio Control Module
from Siemens Industry, Inc. is the master
control module for the MXLV audio system.
The module controls all Voice related func-
tions. It has two yellow LEDs—the TROUBLE
LED indicates ACM-1 troubles and the
TRANSMIT LED monitors network activity.
Refer to Figure 1 for the location of the
LEDs. (These troubles also appear on the
MKB-2 panel.)
ACM-1 has a supervised tone generator
which provides a variety of tones for use
with the system. Each system can have two
of the available tones. The tones are set
with CSG-M. If an application requires tone
backup, use the P6 connector on the
ACM-1 for the BTC-1 Backup Tone card.
(Refer to Figure 1.)
The ACM-1 occupies one network address.
The switch S102 shown in Figure 2 is used
to set the network address that was chosen
in CSG-M for the ACM-1 module.
OPERATIONS
1. The ACM-1 controls and supervises the
preamplifier circuit for the microphone
and wiring for the retractable cord. The
preamplifier circuit controls the volume
of any signal that enters the circuit.
2. When the microphone key is pressed,
the ACM-1 sends the preannounce tone
that was configured in CSG-M, making
the microphone the source for audio
channel 1.
