ATG-2 Audio Tone Generator
ATG-2 Overview The ATG-2 provides user-selected tones for single or dual channel output. The ATG-2
provides several ways to page.
•Direct paging – The ATG-2 microphone with a button switch lets you page through
primary and secondary speaker circuits channels. If used with an optional FFT-7,
the ATG-2 also lets you page through the system from telephones installed
throughout the installation.
Note: For more information on
ATG-2 configuration, refer to
the Voice Modules Section of
the Unimode400 Installation
Manual.
•Remote paging microphone – You can also set up the ATG-2 to pass-through an
audio message (or tone) received from an AMG-1 or another ATG-2. In this
configuration, the ATG-2 serves as an alternate (remote) paging location for the
AMG-1 or main ATG-2. The ATG-2 provides override paging capabilities from the
ATG-2 microphone. All communications go through NAC 1 using ACS mode
(Refer to the Unimode400 Installation Manual for instructions.) connected to the
control panel—unless set up for remote paging microphone operation.
