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.

The ADM’s contact closure inputs are typically used to monitor the amplifier failure contacts of the
central amplifiers to determine amplifier failure. Figure 1 illustrates a typical application for one paging
zone. Figure 2 illustrates an alternate application for one central amplifier and twelve speaker loops.
OTE: (*) indicates that fault detection occurs only while the associated amplifier is not in use.

Figure 1. Single Page Zone - Typical Application
The ADM is comprised of two subassemblies: the 69250-xxx Distribution/Monitor printed circuit board
assembly (PCBA) and the 69248-xxx Central Processing Unit (CPU) PCBA. The ADM mounts in a
Snaptrack™, a grooved plastic channel that allows a PCBA to securely ‘snap’ into place. The
Snaptrack™ provides flexible installation because it may be installed in an equipment rack wherever it is
convenient.
The ADM communicates with the MCU via the CPU PCBA over a bi-directional RS-485 link. The CPU
PCBA monitors the status of the module’s contact clo sure inputs and speaker loop inputs and reports
them to the MCU via this communication link.
The MCU periodically interrogates the ADM to determine its status. The MCU identifies a particular
module on this RS-485 link by its address. (The ADM’s module address is set by rotary hex switch S1,
located on the CPU PCBA.)

WARNING
Incorrect connection of the power source to TB19 or TB20 may cause damage to this assembly.
N
OTES:
• Although power may be daisy-chained between Snaptrack™ modules, the preferred method of
delivering power to these modules is to provide a dedicated cable run from the power supply to each
module.
• The auxiliary power supply is not part of the 10457 Series Card Rack Assembly nor does the card
rack assembly power supply provide power to Snaptrack™ modules. An additional power supply
must be included in the cabinet to support these modules.
• For proper operation, connect the auxiliary power supply return leg to earth ground at the auxiliary
power supply.
• The ground reference for this assembly must be identical to that of the card rack assembly.
• The ADM does not provide any current-limiting for input power. An external fuse of the Slo-Blo
variety, with the appropriate voltage and current ratings, should be provided.

Equipment. GAI-Tronics warrants for a period of one (1) year from the date of shipment, that any
GAI-Tronics equipment supplied hereunder shall be free of defects in material and workmanship, shall
comply with the then-current product specifications and product literature, and if applicable, shall be fit

to be defective in workmanship and/or material under normal and proper usage, or unfit for the purpose
specified and agreed upon, and (b) Buyer’s claim is made within the warranty period set forth above,
Buyer may return such goods to GAI-Tronics’ nearest depot repair facility, freight prepaid, at which time
they will be repaired or replaced, at Seller’s option, without charge to Buyer. Repair or replacement shall
be Buyer’s sole and exclusive remedy. The warranty period on any repaired or replacement equipment
shall be the greater of the ninety (90) day repair warranty or one (1) year from the date the original
equipment was shipped. In no event shall GAI-Tronics warranty obligations with respect to equipment
exceed 100% of the total cost of the equipment supplied hereunder. Buyer may also be entitled to the

of any such third-party warranty will be determined by GAI-Tronics.

shall be performed in accordance with the standard of care with which such services are normally
provided in the industry. If the services fail to meet the applicable industry standard, GAI-Tronics will
re-perform such services at no cost to buyer to correct said deficiency to Company's satisfaction provided
any and all issues are identified prior to the demobilization of the Contractor’s personnel from the work

provided hereunder.

hereunder shall be deemed waived unless such claim is made in writing within the applicable warranty
periods as set forth above. Provided, however, that if the defect complained of is latent and not

be deemed waived unless it is made in writing within a reasonable time after such latent defect is or
should have been discovered by Buyer.
Limitations / Exclusions. The warranties herein shall not apply to, and GAI-Tronics shall not be
responsible for, any damage to the goods or failure of the services supplied hereunder, to the extent
caused by Buyer’s neglect, failure to follow operational and maintenance procedures provided with the
