[A] SD CARD
Supports SD/SDHC cards up to 2GB/32GB. The card contains the following factory supplied system files:
BEEP.mp3 - alert tone played to the user before recording
PRE.mp3 - alert tone played to the PA before announcement
Plus the following optional user supplied files:
000.mp3 - activated with the built-in PLAY button
001.mp3 ~ 009.mp3 - activated remotely with DTMF keys
User may replace or delete these files without affecting system function. If a file is missing on the SD card, the system
will continue to operate without the corresponding audio.

Connections for optional external PLAY & STOP buttons. The buttons should be the momentary contact closure type. Wiring
polarity is not important. See the [H] PLAY & STOP section for functional descriptions.
[C] LINE
The ADS PA-100 is designed to be used with a two wire analogue telephone system. The device must not be connected to a
public exchange line (PABX).
With a regular telephone cord connect the system via this RJ11 jack to the extension port of an analogue phone system, or an
analogue port on a digital phone system. The PA-100A can be accessed by calling the extension
[D] PAGING OUTPUT
This RCA jack provides a line level audio output. Some PA systems may require a control signal in addition to the audio. See the
[E] RELAY section.
[E] RELAY
NC - Normally Closed
NO - Normally Open
C - Common
This output can be used to control the PA system if necessary. It provides a dry contact closure and can be configured
(via the CONFIG DIP switches) to activate in the following two ways:
During broadcasting only - this is suitable when there is background music playing on the PA system. The music will be
interrupted only during the actual broadcasting, not when the system is recording.
During the whole operation - this is suitable when there is no background music. The PA system is seized as soon as the system
starts recording. This guarantees the availability of the PA system when it’s time for broadcasting.

Power input - use the factory supplied power supply only.
[G] INDICATORS
Indicator lights for power, record and relay.
[H] PLAY & STOP

These buttons are internally connected to [B] EXTERNAL PLAY & STOP terminals.
