General Description
Introduction
The SS2000+ Series C web-enabled controller is Federal Signal’s most advanced stand-
alone control unit. The SS2000+ typically interfaces to an analog or digital radio system to
provide radio activation of sirens across a county, municipal, campus or industrial facility.
The SS2000+ has 24 programmable activation buttons secured with a keylock switch and
20 contact closure inputs for interfacing with remote control systems. The hotkeys can
provide specific types of warnings or test activations to notify residents, employees or
students.
The 24 hotkeys are now accessible from a variety of interfaces using a new web interface.
The new web interface can provide improved redundancy allowing multiple SS2000+
units to be used as online backups. Advanced networking features enable the SS2000+
to be connected to Federal Signal’s Commander®control and status monitoring software.
In addition, the SS2000+ can now connect directly to Federal Signal’s CommanderOne®
cloud service for secure web access to hotkeys, messaging and automated activation
from NOAA® EAS events.
The SS2000+ can be used to as an encoder for one-way siren control. Previously using a
SS2000+ allowed activation only from the front panel hotkeys, the physical interfaces or
from a connected PC. The SS2000+ now provides siren activation from CommanderOne
NOAA EAS events/polygons, from a mobile app, or from a web browser over the Internet.
Features
The SS2000+ has the following features.
• Twenty-four activation buttons on front panel with keylock protection
• Twenty optically isolated remote activation inputs built in (activated by dry contact
closure)
• Integrated web server allows users to activate and configure the SS2000+ from
standard web browsers
• Can be controlled and monitored from multiple Commander®computer control points
over a LAN
• Optional web interface to CommanderOne®for automatic activation by NOAA and
secure remote control from standard web browsers over the Internet
• Modbus interface allows the SS2000+ to be controlled by Industrial Controllers

Web Browser Activation
The SS2000+ has a built-in web interface that you can use to activate and configure
the SS2000+ from a standard Chrome®, Edge®, or Firefox®browser over you local-area
network (LAN). Digest Authentication is used for security.
CommanderOne®Cloud Service
You can configure the SS2000+ to connect to Federal Signal’s CommanderOne® cloud
service for automated activation from NOAA® EAS events. CommanderOne also enables
users to securely activate their SS2000+ devices from a web browser over the Internet.
Modbus Interface
The SS2000+ has a Modbus interface to easily interface with Industrial Control Systems.
Mobbus TCP is used to provide activations into an SS2000+ for specific warning
announcements across an industrial plant. You can activate the system using the
SS2000+ or industrial control systems can activate the hotkeys.
Encoding
Program up to three codes under each activation input. There are sixty programmable
functions available. These codes can be Two-Tone, Single-Tone, EAS, DTMF, Federal
Signal Digital Codes (FSK) and activating the three Relay Outputs, or calling another
activation key. Send each activation code from one to three times.
Modes of Operation
You can set the SS2000+ in either standalone or computer mode. In either mode, any
poll requests or activation commands from Commander Software, updates the clock in
the SS2000+ to match the Commander Software time and date. In computer mode, all
reports, status, and activations are logged within the Commander Software.
The SS2000+ can also receive streamed audio and encode activations from Commander
Software and transmit it out as audio.

General Description
Description, Specications, SSLoader + Software, and Operation Manual
Federal Signal www.fedsig.com
Standalone Two-way Operation
Use the SS2000+ in standalone mode; that is, without a host computer application. When
in standalone mode, the SS2000+ does not function as a two-way radio modem for the
Commander Software applications.
In standalone mode, the SS2000+ acknowledges and prints incoming status reports and
alarms from remote devices. Acknowledgments confirm message receipt and keeps
remote devices from repeating transmissions.
The SS2000+ is configured with two lists of unit numbers: one for digital units and one
for DTMF units. Both types can exist in the same system. When a Report – All is executed,
the SS2000+ polls the active units in the digital list first, logging each poll and response.
When complete, the SS2000+ polls the units in the DTMF list, logging each poll and
response. The DTMF status or alarm messages are converted to the same format as the
digital information. The incoming DTMF and digital messages are decoded and displayed
on the LCD.
Computer Mode Operation
The SS2000+ keypad and display are still operational in computer mode, but the
SS2000+ does not acknowledge incoming digital messages. It passes all messages to the
host computer application.
Automatic Logging
The SS2000+ displays all incoming and outgoing messages on its LCD display. The
SS2000+ prints all status reports on a line printer if the printer is enabled in the
configuration. If Com Port 2 is configured for printer messages, the statuses and alarms
are sent there as well. The SS2000+ also logs each time it is powered up, all manual
encode activations, outgoing poll requests, and the results of each step in the self test
procedure.
Testing and Alignment
The SS2000+ has a calibrate function and an LED bar graph to aid in setting receive and
transmit levels. It also incorporates a comprehensive built-in test routine to test every
circuit of the unit. The internal monitor speaker allows the user to hear all incoming and
outgoing transmissions to aid in system setup and troubleshooting.
Audio Inputs
The SS2000+ has two line-level inputs, each with its own PTT line, a local mic input with
PTT, and an XLR balanced input incorporating a VOX PTT for balanced or distant mics.
The XLR input can provide a ghost supply for amplified mics. Use amplified or non-
amplified microphone.
Serial Ports
The SS2000+ has two serial ports. Use COM1 for interfacing with Commander Software
or Encoder Software. Use COM2 to send printer messages or receive text messages to
a display or peripheral device. Also, use COM2 to interface with Commander Software,
Encoder Software, or an external radio modem.
Relay Outputs
The SS2000+ has three Relay Outputs that you can program to activate when an
activation button is pressed. Each relay has an o time and an on time. Alternatively,

12
General Description
SS2000+ Series C
Federal Signal www.fedsig.com
configure each relay to activate when the unit has not been polled in 30 minutes, when
an RTU reports a fault, or when PTT or Carrier Detect are active.
Activation Buttons
Located on the front panel of the SS2000+ are twenty-four programmable activation
buttons that activates functions one through twenty-four.
Configure each activation function for Auto Prompt Send or Auto Send. Auto Prompt
Send prompts you to press the SEND button after an activation button has been pressed
before initiating the activation. Auto Send sends the code out when you press the
activation button without being prompted to press SEND. The same method is used with
Auto Prompt Send Auto Report and Auto Send Auto Report modes, which include and
automated system-wide poll after activation. You can print each activation and status
reports to a printer.
Remote Activation Inputs
Located on the back of the SS2000+ are twenty external activation inputs that can be
driven by a momentary contact closure. These inputs are optically isolated and activate
buttons one through twenty. Debounce time for remote inputs is 250 ms. Inputs should be
closed > 250 ms and released after the activation. An input held closed for extended time
will not generate multiple activations but it will prevent other inputs from activating until
the input is released. These twenty external (rear mount) inputs are factory set to activate
activation inputs one through twenty. Modify the jumpers on the internal PCB to allow the
inputs to be used for additional functions. For example, use the remote inputs as inputs
twenty-one through forty or forty-one through sixty. See “Table 5 Input Board Addressing”
on page 18.
Transceiver Interface
The transceiver interface features a balanced 600-ohm input and output (optional
10kilohms) and can accept a wide range of transceiver types and levels. The transmit
audio from other encoding equipment can be interrupted during the transmissions of
the SS2000+ by the PTT relay. The unit also monitors if other equipment is currently
transmitting before attempting to transmit. Carrier detect can work with either polarity or
from a VOX.

Connecting the Transceiver Interface
Unbalanced Interface (TB2)
To connect an unbalanced interface:
1. Connect the PTT relay COM output (TB2 pin 1) to TB10 - Ground.
2. Connect the PTT relay N.O. output (TB2 pin 2) to the transceiver and PTT input.
3. Connect the Carrier detect ground (TB2 pin 10) to the transceiver’s ground.
4. Connect the Carrier detect (TB2 pin 9) to the transceiver’s carrier detect output.
Jumper the unit to accept either active low or active high carrier detect. If the carrier
detect is not available, jumper the unit for VOX.
5. If other equipment is using this transceiver, connect its transmit audio to TB2 pin4.
When the SS2000+ is transmitting, it interrupts this TX audio.
6. Connect the Transmit audio Hi output (TB2 pin 5) to the transceiver’s transmit audio
input.
7. Connect the Transmit audio Low (TB2 pin 6) to TB10 - Ground.
