Broadcast Deactivation – The Desktop Controller is equipped with a "Deactivate" pushbutton that,

when pressed, will immediately deactivate all speakers assemblies and return them to their sleep or rest

state. This will allow for manual deactivation of the speaker assemblies if an erroneous signal is keeping

the speakers' amplifier circuits active (line noise, RF interference, etc.).

The Model ACC2500 Desktop Controller can be programmed to display each zone as an alias on its LCD

display. Alias simply means a "name" for the zone or address. The same can be programmed for each

individual unit. To broadcast a pre-programmed message/alarm to a specific zone or unit, the Desktop

Controller operator will press the Zone UP or DOWN button to locate the desired zone, press the Alarm

UP or DOWN button to locate the desired alarm (evacuate, tornado, all clear, etc.), the press the

TRANSMIT button. The alarm will begin broadcasting only in the selected zones or units. The audio

that will be heard from each speaker or stanchion selected will also be heard over the Desktop

Controller's integral speaker. If the handset if off-hook, this audio will be heard over the handset receiver

(earpiece). The message/alarm will play for the duration it has been programmed to broadcast or until the

DEACT button is pressed to deactivate all units.

If a the Desktop Controller operator desires to broadcast a live voice message while a pre-programmed

message/alarm is in progress, they simply press the transmit button and talk or lift the handset from its

cradle and talk while pressing the handset pressbar. The pre-programmed message/alarm audio level will

be reduced or muted (depending on programming) for the duration of the live voice broadcast

(TRANSMIT button or pressbar must be activated during live voice broadcast).

Releasing the

TRANSMIT or pressbar will allow the pre-programmed message/alarm to return to normal volume.

If the Desktop Controller operator desires to simply broadcast a live voice message, they must select the

zone alias or enter the desired zone code via the keypad, press and hold the TRANSMIT button (or

handset pressbar), and begin speaking when "TALK NOW" appears in the LCD display.

Model 10959-903 Audio Messenger Interface

The Model 10959-903 Audio Messenger Interface (AMI) provides superior quality digital tone/speech

generation and telephone interface and feedback elimination capability. A Compact Flash™ Card Kit

stores the configuration programming, the voice and tone recordings, and provides CD-quality sound

reproduction.

Direct RS232 access from the Model ACC2500 Desktop Controller allows control of up to 125 pre-

recorded tone, speech, or tone/speech messages. Each alarm/message can be programmed for continuous

play, timed duration, or number of repeat cycles. Pre-recorded speech messages can be wave file or MP3

format.

LIVE VOICE TELEPHONE SYSTEM ACCESS

In addition to the head-end controller operation, the system can be accessed via the campus telephone

system. An extension number would need to be provided for telephone access. Upon dialing this

number, the telephone operator would receive verbal instructions followed by a splash tone. Upon receipt

of the splash tone, the operation will dial the DTMF access code of the desired voice broadcast location.

As with the deskset, this can be an individual stanchion assembly, a zone or group, or all stanchion

assemblies. This is a voice broadcast operation only, as no alarms can be activated from the telephone.

The public address system can also be accessed from an existing VHF (154 - 174 MHz) or UHF (450 -

470 MHz) radio system. Radio equipment with integral DTMF keypads (DTMF encode) is necessary to

perform the live voice access. The same DTMF codes utilized by the telephone system operation

previously mentioned will be utilized by the radios. The radio operator would simply select the operating

frequency and, while engaging the PTT, transmit the DTMF code and begin speaking into the radio

microphone. This is a voice broadcast operation only, as no alarms can be activated from a radio.
