Applications
The following section describes three applications for the DS100 when connected to
another Federal Signal speaker.
Configuring the RF100 with the DS100 (120 VAC)
To create a multi-directional system, connect the RF100 with up to three DS100s to use
the features of the controlling speaker (RF100), such as prerecorded voice messages and
live PA, through the DS100s. See “Figure 19 RF100 Connected to Three DS100s (120 VAC)
Wiring Power to the Interconnect Board
AC power is brought over from the controlling speaker to the DS100. The power passes to
JP5 to connect to an additional DS100.
IMPORTANT: The total AC current draw from the controlling speaker should not exceed
8.5 amperes. This is the AC for powering the speaker.
To wire power to the DS100:
1. Bring AC power from JP6 on the RF100 to JP4 on the DS100’s Interconnect Board.
The power passes to JP5.
2. Connect JP5 to the next DS100 at JP4.
3. JP6 on the Interconnect Board connects to the DS100’s Power Supply Board.
Wiring AC to the Interconnect Board
To wire AC between the DS100s: connect from JP5 on the DS100 to JP4 on the next
DS100.
Wiring Audio to the Amplifier Board
Audio from JP2 on the RF100 controller board is brought to JP3 on the DS100 amplifier
board. JP3, on the amplifier board, connects to JP7, which can be connected to additional
DS100s.
To wire audio to the DS100:
1. Ensure all audio potentiometers are set to the max by default on both the RF100 and
DS100s by turning the post of the potentiometer all the way up (fully clockwise).
2. Ensure that the jumper JP5 on the DS100 Amplifier Board is set to the 10 V
RMS
position
to make it compatible with the RF100 audio output. The RF100 outputs a 10 V
RMS
signal.
3. Connect JP2 on the RF100 to JP3 on the DS100’s Amplifier Board.
4. Connect JP7 on the DS100’s Amplifier Board to the next DS100 at JP3.
