Introduction
The GT1000/5000 Emergency Notification and Communication System is designed for use in harsh
industrial environments. The 69253-001 Audio Generator Interface (AGI) is an integral assembly in this
system. The AGI is responsible for generating the tone messages that are broadcast over the syst em
spea kers du ring emergency condit ions. The 69254 Series Master Control Unit (MCU) and the AGI
maintain const ant communication links. Thes e links ar e continua lly supervised by both the MC U and the
AGI to verify proper working condition.
How to Use the Assembly
The AGI conta ins four tone s ources:
• Primary Alarm Generator • Backup T one G enerat or
• Fa il- safe Tone Generator • Supervisory Tone Generat or
The AGI c ontrols the Fa il- safe Tone Genera tor. The Mast er Cont rol Unit regulates the output of the
Back- up and the Supervisory T one Generat ors. The MCU also controls the Primary Alarm Genera tor.
The following informat ion defi nes the purpose of each tone generator.
Primary Alarm Generator
The P rimar y Alarm Generat or produces alarms from a library of tones u pon command from the MCU. If
multiple alarms are activated, the Primary Alarm Generator plays the alarm tones in the order they are
received according to their priority. The MCU communicates with the Primary Alarm Generator via the
control rack backplane. The MCU uses this communication path to supervise the Primary Alarm
Genera tor. The MCU per f orms this function by periodically c ommanding the Pr ima ry Alarm Genera tor to
play a pre-determined tone.

The MCU monitors the output of the Primary Alarm Generator to detect the presence of this tone. Note
that dur ing this t es t, t his tone is not c onnected to any backp l ane page resources. The Primary Alarm
Genera tor ma y be connected to one of the two backplane page resources on M CU command. The Primar y
Alar m Generat or ca n generat e t ones or p layback digitally recorded and stored speech/audio messa ges with
the opt ional fla sh card memory.
Backup Tone Generator
In the event t hat t he Primary Alarm Genera tor f ails t o respond to an M CU command, the MCU s witches
the ba ckplane page r es ource from the Primar y Alarm Generat or to t he Backup Tone Generator. The
Backup Tone Generator then assumes operation. This event is reported by a printer attached to the control
unit or by an access panel containing a vacuum fluor escent disp lay atta c hed t o the contr ol u nit. During
normal c onditions, the MCU regularly a c tivat es the Bac kup T one G ener ator to t es t the communica tion link
and ensu re proper working order. However, during this test, the Backup Tone Gener ator au dio is not
switched to any backplane page resources.
Fail-safe Tone Generator
The Fail-s afe Tone G ener ator can be act i vated by the AGI if communication wit h the MCU is disr upted.
This oc c urs if the MCU is malfunct ioning. The F ail-safe Tone Gener ator remains active unt il
communicat ion with the MCU is r es tored. This alerts personnel that a t roub le condition exists between the
MCU and the AGI. The Fail-safe Tone Generator is linked directly to the 10457 Series backplane,
allowing the Fail-safe Tone Generator to operate wit hout interference from the MC U.
Supervisory Tone Generator
The Supervisory Tone Genera tor produces a tone that is used by t he M CU to survey central amplifiers and
associated spea ker ru ns. This health check is p erformed periodically at t he command of the MCU. If t his
health check f ails at any point, a message is repor ted by a p rinter att ached to t he control unit or b y an
acces s panel containing a vacuum fluorescent display attached to t he control unit. The message identifi es
the speaker loop at which the failure wa s detected.
Additional Features
In addition to providing the tones above, the audio genera tor also provides the following f eatures:

Align the PCBA into the upper and lower tracks for the slot. Slide the PCBA towards the rear of the card
ra c k until the PCBA comes in contact with a connector on the bac kp l ane. F irmly press on the front b ezel
until the PCBA is seated. Secure the PCBA to the card rack by tightening the two screws located on the
front bezel.
Optional PCMCIA Memory Card Installation
The PCMC I A memory card ma y be used for adding opt i onal speech mess ages. If the P CMCI A is being
installed for t he f irst time or if the s peech messages are b eing changed, complete the following instruct ions.
The 69253-001 AGI does not need to be powered down for insertion or removal of the PCMCIA memory
card. Insert the memory card through the rectangular cut-out of the AGI bezel, ensuring that the label on
the top of the memory card faces to the right. Slide it until fully seated in the PCMCIA socket. Once fully
seated, the memory card should pr otru de approximately ¼ inch from the AGI bezel. Note: The memory
card and it s socket are polariz ed for proper ins ertion – do n o t force card i n t o s o cket .
The AGI s enses the insertion of the P CMCIA memory card and resets the AGI’s CPU. T h e PCMCIA
memory card is then read by the AGI’s CPU. The MCU's software configuration must be configured, if
not previously done, so tha t the AGI c an recogniz e t he s peech files loaded into the PCMCI A memory card.
If new or additional alarm messages are desir ed f or your partic u l ar system, then the PCMCI A memory card
must be updated. In addition, the MUC must be reconfigured. Please contact GAI-Tronics for assistance.
To remove the PCM CIA memory card, s i mply grasp the card and pull it out f rom the AGI. The audio
generator’s CP U resets, and upon restart, it recognizes that the ca rd has been removed and default s to
tone-only a larms. If an alarm message is being broadc ast when the PCM CIA memory card is removed, the
speech message is canceled and t he audio generator resets and defaults to tone- only f or the a l arm.
Operation
Configu ration - T he AG I tones a nd messages are configured by the MCU soft ware configur ation p acka ge.
Refer to the system manual for all operating details.
