Test Tone Generator Module
Test Tone Monitor Module
The Test Tone Generator Module, Model 12393001, is a highly functional option for use on Public
Address systems. It provides the tone signal
generation and a method to mix the tone signal
into the required audio pathways. This tone signal
serves two purposes. First, it provides a test
signal that is injected into the audio pathways and
is monitored at various points throughout the
system. Secondly, if the system is utilizing the
Speaker Master/Remote boards for grouping and
remote tapping, the Test Tone Generator will
provide an inaudible source of power to the
speaker remote boards.
The Test Tone Monitor Module, Model 12399-001,
interfaces with the Test Tone Generator Module in
order to verify its point-to-point line integrity. The
tone monitor has 16 input channels that can be
dedicated to any audio endpoint whether low-level
(0 dB) or high level (100 Vrms).
The tone generator’s output is programmable
and adjusted by the microcontroller.
The tone monitor uses frequency-programmable
filters for the detection of the test tone. The 16
monitoring channels are multiplexed down to 8
detection channels. These are further divided into
2 groups of frequency-programmable channel sets
(channels 1 through 8 and channels 9 through 16).
A detection on any given monitoring channel
results in a relay closure with an integral LED
indicator that is dedicated to that channel. The
closure stays active as long as the tone is present
within a latency of 1 second.
