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.
