Control
Module
The Audio Control Module is a dual channel electronics package, which
interfaces with the paging microphone operator interface (2-MIC) and
the firefighter telephone (2-TEL). Two integral tone generators provide
alert and evacuation signaling. Two auxiliary pre-amp level (1 V) inputs
handle pre-recorded messages or other external sources. Each of the
two audio output channels has a Class B or Class A, pre-amp level (1
V) output, to feed the audio amplifiers.
The Audio Control Module mounts on the rear of the enclosure and
provides terminals for the external audio inputs, two audio risers, and
RS-485 data.
