2001-6030 MICROPHONE AND ENCLOSURE MODULE DESCRIPTION
INTRODUCTION (Refer to Fig. 1)
The 2001-6030 Microphone and Enclosure Module contains a microphone, a microphone enclosure and two
positions for daughter cards (usually the oscillator control module and the dual pre-amp monitor module). The
microphone is used to transmit voice messages over the 2001 Voice Communications System’s speakers.
The microphone contains a “Push-to-Talk’ switch which, when pressed, deactivates tape player, music and all
oscillators, and allows any output signals from the voice coil cartridge (Fig. 2) to transmit to the primary and
secondary preamplifiers via the mike interface transformer.
DRAWING REFERENCE
The enclosure module circuitry is shown on the following drawing:

TONE OSCILLATOR MODULES DESCRIPTION
INTRODUCTION (Refer to Fig. 5)
The tone oscillator modules generate audio-frequency signals for the 2001 Voice Communications System. The
audio signal generated by the tone oscillator modules produce specific tones when amplified and fed to the
system’s speakers. The following list identifies the tone oscillator modules that are available to the voice
communications system:
2001-6032 Slow Whoop (tone ascends from 200 to 830 Hz in 2.5 seconds).
2001-6033 Wail (tone ascends and descends from 600 to 900 Hz).
2001-6034 Beep (470-Hz tone).
2001-6035 Horn (continuous 470-Hz tone).
2001-6036 Stutter (470-Hz tone, .OOl seconds on and .OOl seconds off).
2001-6051 Chime (700-Hz tone with a 1.5 second delay time).
2001-6052 Coded Horn (pulsing 470-Hz tone).
2001-6057 Hi/Lo (554-Hz hi tone and 550-Hz lo tone. Hi tone on 100 ms and lo tone on 400 ms).
Four positions on the audio control module are dedicated for the oscillator modules. The positions are designated
as follows:
Alarm Osc 1 (required)
Alarm Osc 2 (required)
Auxiliary Osc 1 (optional)
Auxiliary Osc 2 (optional)
Under normal conditions, the alarm oscillators are
constantly running and the auxiliary oscillators are off. All
oscillators are controlled automatically by the audio
control module or manually by the switches located on
the oscillator control switch module.

2001-6052 WD No. 841-400 (Coded Horn Oscillator)
2001-6057 WD No. 556-467 (Hi/Lo Oscillator)
MODULE FUNCTION (Refer to Fig. 6)
The operating voltage for the tone oscillators is fed to pins PC1 (+ 12V) and PC3 (-OV). The oscillator’s circuitry
generates an audio frequency signal and sends it out PC2 for preamplification. When - OV is fed to pin PC1 , the
oscillator stops generating its frequency (osc stop).
When two oscillator modules are interconnected at pin PC7 (as is the case with alarm oscillators 1 and 2 when
no tape player is used), their tone signals must be synchronized or else a trouble condition will occur.
