Description
The following modules are required to
integrate voice into the MXL.
ACM-1 Audio Control Module
The ACM-1 Audio Control module is
the master control module for the
MXLV audio system.
The 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.
There is a microphone preamplifier
circuit with backup preamplifier which
controls the volume of any sound that
comes into the circuit. The module also
has a circuit that monitors the micro-
phone key. Both the preamplifier circuit
and the retractable cord are supervised.
The ACM-1 also controls a small local
speaker in the MMM-1 module.
Three supervised riser circuits provide
low power audio signals to the OCC-1
to be sent to power amplifiers.
The Audio Control module communi-
cates with the VSM-1 Voice Switch
modules, the VLM-1 Voice LED mod-
ules and the VFM-1 Voice Fan Control
modules that are part of the system.
The VSM-1 modules provide firefighters
with a means of controlling nonauto-
matic functions of the MXLV System.
The ACM-1 controls the wardens
page that comes from the TMM-1
Telephone Master module. When
activated, the wardens page becomes
the audio source for selected speaker
zones.
