Configuring the RF100 with the DS100 (24 VDC)
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 20 RF100 Connected to Three DS100s (24 VDC)
Wiring Diagram” on page 32. For a list of options lights, see “Using Optional Warning
Wiring Power to the Interconnect Board
To wire power to the DS100s:
1. Disconnect and remove the wires that connect the power supply board to the
Amplifier Board.
2. Bring DC power from an outside source into JP14 on the RF100 board.
3. Wire to JP1 on the DS100’s Amplifier Board.
4. Connect JP1 to the next board.
Wiring Audio to the Amplifier Board
Audio is brought over from the RF100 at JP2 to the Amplifier Board at JP3. Audio comes
back out of the Amplifier Board on JP7 and can be connected to an additional DS100.
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.
You can attach a light to the RF100 at JP15.
Configuring the 300VSC SelecTone with the DS100 (120 VAC)
The Model 300VSC SelecTone® Command Unit is a central control device that is capable
of generating up to four different tone signals on a line that is connected to remote
speaker/amplifiers in a SelecTone® System. Connect the 300VSC with up to three
DS100s to use the features of the controlling speaker (300VSC). See “Figure 21 300VSC
SelecTone Connected to Three DS100s (120 VAC) Wiring Diagram” on page 33.
Wiring Power to the Interconnect Board
To wire power to the DS100:
1. Connect the power from the power cord connector on the 300VSC to the JP4 on the
DS100’s Interconnect Board. The power passes to JP5.
2. Connect to the next DS100 Interconnect Board at JP1.
