Introduction
This document discusses installing, operating, and maintaining the 12580-001 Amplifier Distribution/
Monitor Module (ADM), which provides the following features:
• Distributes audio to central amplifiers
• Verifies the integrity of speaker loops
• Monitors amplifier failure contacts
• Communicates with the Master Control Unit
How to Use the Assembly
This section describes applications for the Amplifier Distribution/Monitor Module, its hardware
configuration, block diagram, interfaces, and installation. Because this assembly is controlled by a 69254
Series or 69440 Series Master Control Unit (MCU) and is set up in the MCU’s configuration software,
there are no operating controls or software configuration for the ADM. Refer to the MCU Configuration
details in your system manual for all operation information.
Application
The Amplifier Distribution/Monitor Module is used to distribute audio to up to six central amplifiers. It
is also used to verify the integrity of the related speaker loops and to monitor up to six amplifier failure
contacts, reporting their status to the MCU. The ADM’s speaker loop inputs allow it to detect various
fault conditions on any of up to six speaker loops. These fault conditions include ground faults, cable
breaks*, wire-to-wire short circuits*, and amplifier failures.
