General Description
Introduction
The Directional Speaker (DS100) is an outdoor or indoor amplified speaker that can be
used as a warning and alerting device. The DS100 contains an internal Interconnect Board
to simplify wiring to additional DS100s and optional visual alerting devices. Use the DS100
to connect to another Federal Signal speaker (the controlling speaker) to broadcast
high-quality, high-powered tones, prerecorded voice messages, and live PA. In addition,
connect to other 10 or 25VRMS audio generation equipment such as amplifiers and tone
generators. Add a Federal Signal light to the speaker to include visual indicators. The
DS100 has an internal 100-watt amplifier/driver to deliver tone warnings and intelligible
voice messages from the controlling speaker’s stored memory.
The DS100 is powered from either 120/240 Vac or 24 Vdc. When the DS100 is powered
from AC, it can use the Interconnect Board to activate AC-powered visual alert devices.
When the DS100 is powered from DC, it brings power in from an outside source. The
DS100 has a 1/2-inch NPT opening on the top of the speaker for simple installation of
pipe mount devices such as strobes. The bottom of the speaker has three 3/4-inch NPT
openings to allow access to power, relay outputs, and activation inputs.
The DS100 comes with an adjustable stainless steel wall mount bracket that allows the
angle of the speaker to be adjusted. Optional pole mount brackets are available for small
and large diameter poles.
Features
The DS100 has the following features:
• Outdoor or indoor speaker that contains an internal Interconnect Board to simplify
wiring to additional DS100s and optional visual alerting devices.
• Combine with a controlling speaker such as an RF100 for a multi-direction system.
• Combine with a 10 or 25 VRMS audio signal from a distributed amplifier, for example,
Federal Signal 300VSC SelecTone®Command Unit
• Speaker rated at 120 dBa for tones and 114.5 dBa for voice at 10 feet
• Broadcasts live voice, text-to-speech, and prerecorded voice or tone files by
connecting to a controlling speaker such as an RF100 or Informer100. Contact
Technical Support for details.

unit, you need to wire power and relays to the Interconnect Board. For the DC-powered
unit, you need to wire a 24 Vdc input to the Amplifier Board.
Wiring the Audio to the Amplier Board for AC and DC Units
Audio is brought over from the controlling speaker or another audio source to JP3 on
the Amplifier Board. Audio comes back out of the Amplifier Board on JP7 and can be
connected to an additional DS100 if used.
AC Units Only
Wiring Power to the Interconnect Board
AC power is brought over from the controlling speaker or another source to JP4 on the
DS100’s Interconnect Board. The power passes to JP5 to connect to an additional DS100
is used. Verify that the switch on the Power Supply Board is set correctly.
IMPORTANT: The total AC current draw from the controlling speaker should not exceed
8.5amperes. This is the AC for powering the speaker.
Wiring the Relays to the Interconnect Board
Relay outputs from the controlling speaker are connected to JP1. They pass on to JP2
and can be connected to an additional DS100 if used. You can attach a light to the DS100
and connect it to one of the four relay outputs on JP3. Each relay output can handle a
maximum total load of 1 ampere.
DC Units Only
Wiring 24 Vdc Power to the Amplier Board
To wire 24 Vdc power to the Amplifier Board:
1. Disconnect and remove the wires that connect the power supply board to the
Amplifier Board. See “Figure 13 DS100 Wiring Schematic for DC Powered Unit” on
page 22.
2. Bring 24 Vdc from an outside source to JP1 on the Amplifier Board.
