GENERAL
The proposed GAI-Tronics Public Address/Alarm System consists of the following items:
Model ACC2500 Desktop Controller
Model 10959-903 Audio Messenger Interface
Model GTG08081 PA Interface Assembly (if applicable)
RF Stanchion Broadcast Assemblies (if applicable)
RF Addressable Amplified Speakers (if applicable)
Audio Distribution Cabinet (Model GTG08071), if required
Appropriate Radio Equipment (provided by others)
The communication medium between the ACC2500 Desktop Controller and the 10959-903 Audio
Messenger Interface will be via customer-provided Cat 5e/6 cable with RJ-45 connections.
maximum distance allowable between the ACC2500 and the 10959-903 cannot exceed a total of 50 feet.
The audio output of the Audio Messenger Interface connects to an appropriately sized Audio Distribution
Cabinet (96, 48, or 24 circuits) via a twisted pair. An audio connection between Audio Distribution
Cabinets or between each distribution cabinet and its associated speakers or stanchion assemblies is also
via a twisted pair. Note that wiring for the telephone is not indicated on the Interconnection Diagram;
only broadcast wiring is displayed.
The Model GTG08071 Audio Distribution Cabinet is designed to accept a 600 Ohm, audio signal input
and provide up to 96 balanced outputs. Additionally, a single dry contact closure output is available when
audio is received from the AMI. This output can be used for external device activation such as a strobe,
bell, etc. It can also be used as a PTT control for a base radio. Each audio output can connect to any
device requiring a balanced, 600 Ohm, 0 dBM input. These include:
GAI-Tronics' RF Addressable Amplified Speakers (13363, 13373)
GAI-Tronics' RF Stanchion Broadcast Products (234SBA, 234SBM)
Radio Base Station (audio and dry contact closure connection required)
Central Amplifier Equipment
GAI-Tronics' RF PA Interface Assembly (GTG08081)
The Public Address speaker system will be capable of being accessed from the Model ACC2500 Desktop
Controller with pre-recorded alarms and voice messages, from the existing telephone system (live voice
access only), or from the existing radio system (live voice access only). Note that access from the radio
system requires radios that are equipped with DTMF keypad (DTMF encode).
OPERATION
RF Addressable Amplified Speakers, RF Stanchion Broadcast Products, and RF PA Interface
Assemblies
Each Addressable Amplified Speaker (13363 or 13373) and Stanchion Broadcast Product (234SBA or
234SBM) includes an addressable (via DTMF), integral amplifier and built-in RF receiver. The Model
GTG08081 Public Address Interface Assembly includes addressable circuitry and a built-in RF receiver.
Each device is capable of being programmed for up to eight (8) DTMF access codes. The first
programmed access code will always be the individual unit's address. This address will be used not only
to broadcast specifically from that unit, but also to remotely adjust that unit's output volume level
(volume adjustment pertains to stanchion broadcast products and amplified speakers only).
