SAFETY NOTICES
People’s lives depend on your selection of suitable equipment and installation sites and
your safe installation, service, and operation of our products. Federal Signal recommends the
following publications from the Federal Emergency Management Agency for assistance with
planning an outdoor warning system: 1. The “Outdoor Warning Guide (CPG 1-17), 2. “Civil
Preparedness, Principles of Warning” (CPG 1-14), 3. FEMA-REP-1, Appendix 3 (Nuclear Plant
Guideline), and 4. FEMA-REP-10 (Nuclear Plant Guideline). Contact Federal Warning System’s
Customer Care Center at: http://www.federalwarningsystems.com or 1-800-524-3021 for
further information about these publications.
It is important to read, understand and follow all instructions shipped with this product. In
addition, listed below are some other important safety instructions and precautions you should
follow.
PLANNING
•If suitable warning equipment is not selected, the installation site for the siren is not selected
properly or the siren is not installed properly, it may not produce the intended optimum
audible warning. Follow Federal Emergency Management Agency (FEMA)
recommendations.
•If sirens or speakers are not activated in a timely manner when an emergency condition
exists, they cannot provide the intended audible warning. It is imperative that
knowledgeable people, who are provided with the necessary information, are available at all
times to authorize the activation of the sirens or speakers.
•When sirens are used out of doors, people indoors may not be able to hear the warning
signals. Separate warning devices or procedures may be needed to effectively warn people
indoors.
•The sound output of sirens is capable of causing permanent hearing damage. To prevent
excessive exposure, carefully plan siren placement, post warnings, and restrict access to
areas near sirens.
•Activating the sirens or speakers may not result in people taking the desired actions if those
to be warned are not properly trained about the meaning of warning sounds. Siren users
should follow FEMA recommendations and instruct those to be warned of correct actions to
be taken.
•A siren or speaker that doesn’t work won’t provide any warning. After installation, service, or
maintenance, test the mass notification system to confirm that it is operating properly. Test
the system regularly to confirm that it will be operational in an emergency.

•If future service and operating personnel do not have these instructions to refer to, the siren
system may not provide the intended audible warning and service personnel may be
exposed to death, permanent hearing loss, or other bodily injury. File these instructions in a
safe place and refer to them periodically. Give a copy of these instructions to new recruits
and trainees. Also give a copy to anyone who is going to service or repair the siren.
People’s lives depend on your safe installation, service and operation of our products. It is
important to read, understand and follow all instructions shipped with this product. In addition,
listed below are some other important safety instructions and precautions you should follow:
INSTALLATION & SERVICE
•Electrocution or severe personal injury can occur when performing various installation and
service functions such as making electrical connections, drilling holes, or lifting equipment.
Therefore experienced electricians in accordance with national, state and any other
electrical codes having jurisdiction should perform installation. All work should be performed
under the direction of the installation or service crew safety foreman.
•The sound output of sirens or speakers is capable of causing permanent hearing damage.
To prevent excessive exposure, carefully plan siren placement, post warnings and restrict
access to areas near the sirens. Sirens and distributed speakers may be operated from
remote control points. Whenever possible, disconnect all siren power including batteries
before working near the siren.
•After installation or service, test the siren system to confirm that it is operating properly.
Test the system regularly to confirm that it will be operational in an emergency.
•If future service personnel do not have these warnings and all other instructions shipped

SECTION I
1.1 General Description
The UltraVoice Indoor Controller (UVIC) is designed to fulfill the need for an indoor
electronic controller that is smaller and less expensive than the full size UltraVoice
outdoor warning siren controller. It shares the same control board and amplifiers as the
standard UltraVoice but is limited to 800 total Watts of amplifier power, and uses a
single, wall-mountable NEMA1 / UL Type 1 rated enclosure that has a built-in lock.
The use of smaller, sealed VRLA AGM type batteries minimizes battery out-gassing and
makes the controller better suited for indoor operation.
Model UVARM: The UVIC supports an optional Audio and Relay Output Module (model
UVARM) that provides three audio outputs and four relay outputs to enable the UVIC to
be connected to existing PA systems or other auxiliary devices.
Model UVLOC: An optional Local Operation Console (model UVLOC) enables users to
control the UVIC from an easy to use pushbutton control panel. The panel is connected
to the UVIC with a standard CAT5 network cable and may be located up to ½ mile away
from the UVIC controller. The UVLOC is remotely powered from the UVIC and requires
no local power source of it’s own. The panel measures only 10” x 4.75” x 3” (L x W x D)
and is easily wall mounted. The UVLOC provides control for 7 digital recordings: Live
P.A., P.A. Recording from an integrated microphone, Recorded P.A. Playback, and two
Auxiliary user programmable functions.
Model UVIC25ST: An optional 25 volt step-down transformer may be required to
convert 70 volts to 25 volts, depending on location and installation.
Model UVIC25SD: An optional 25 volt step-down transformer may be required to
convert 70 volts to 25 volts, depending on location and installation. The UVIC25SD
includes two step-down transformers in a NEMA 4X fiberglass enclosure.
Model UVIC: The amplifiers and optional equipment are all modularly constructed to
ease removal without disconnecting a large number of wires. In most instances, field
service is limited to replacement of a slide out module, which can be performed by non-
technical personal with only a screwdriver.
Activation codes, command sequences, and operating parameters are uploaded from
an IBM compatible computer through the RS232 port located on the front panel or over
the radio channel with the Federal Commander Digital System. All user information is
stored in non-volatile FLASH memory, immune to power and battery failure.
Refer to Figures 1.1, 1.2, 1.3 and 1.4 for reference.

1.4 Motherboard Description
The Motherboard for the UVIC is a scaled down 800 Watt version of the 3200 Watt
UltraVoice product. The board is primarily a passive back plane that provides the
electrical connections between the Microprocessor Control board, the Audio and Relay
output board, and the UV400 amplifiers. In addition, it provides connections for field
wiring and a relay output.
The UVIC Motherboard is limited to two amplifier slots. It uses the same style
connectors as the UltraVoice except for the removable fused 50A, 24VDC power input
and the 50A, 24VDC output connector.
The Motherboard has a fused normally open relay output. The relay is normally
programmed to close while a control function is active. An LED indicator turns on when
the relay is active.
Capacitor C1 and inductor T1 are used to filter the 24VDC power source. This filtered
power is fused by F2 and is routed to JP1, JP2, JP6 and JP7.
1.5 Configuration
Each modular UltraVoice siren contains the following configuration parameters, which
are configured by the user:
1. Unit Type
2. Unit Address (see below)
3. RF Frequency
4. Single-Tone or Two-Tone Timing (A-time, B-time, S-time)
5. EAS Location Codes
6. 128-bit Encryption Key
7. Security Key

Federal Signal UltraVoice
Installation and Operation Manual
GENERAL DESCRIPTION
18
Unit Type
The Unit Type is set to the type of siren this unit is controlling, and is usually determined
by the number of cells in the speaker array. When setting up the unit type, the user
selects from a menu with the following choices:
UV1 1 - UV400 Amplifier, 400 Watts total power
UV2 2 - UV400 Amplifiers, 800 Watts total power
Unit Address
Address Switch
The Unit Address is a three-digit number with a range of 001-255. The unit address is
set via dipswitch S1. S1 Off position indicates active position. Add binary active switch
positions to get ID address.
Switch
number 1 2 3 4 5 6 7 8
Binary
number 1 2 4 8 16 32 64 128
Example: Switch number 1, 2 & 3 is binary number 1, 2 & 4, which when added, would
equal unit address 7.
Programming details are in the software manual. The ID address is stored at power up
of the controller. If the ID address is changed, the power (battery and AC) must be
turned off and then on.

Federal Signal UltraVoice
Installation and Operation Manual
GENERAL DESCRIPTION
19
RF Frequency
For units equipped with the optional integral radio receiver, the RF Frequency
configuration parameter sets the frequency of the radio channel. Changing this
parameter from its factory setting may require re-alignment of the radio for maximum
performance. The value entered must fall within the range specified for the receiver
band equipped.
Single-Tone, Two-Tone Timing
For Two-Tone activated units, the Two-Tone Timing parameters set up the time
duration of the activation tone codes. The three parameters, A-Time, B-Time, and S-
Time; sets the time duration for the A-tone, B-tone, and Single-Tone respectively. Note:
The Two-Tone timing parameters are minimum values only. The actual tone times may
be longer than the specified times.
EAS Location Codes
Up to three location codes may be assigned for EAS activation. For activation to occur,
the location code of the received EAS message must match one of the three assigned
codes.
Units cannot be programmed for both Tone and EAS activation at the same time.
Therefore, when using EAS decoding, the A-Time, B-Time, and S-Time parameters
above must be set to zero. The UVIC is capable of being programmed for EAS, DTMF
and Federal Digital decoding at the same time. Refer to www.fcc.gov for further
information about EAS messages.
128-bit Encryption Key
For MSK activated units, 128-bit data encryption provides security against malicious
operation or monitoring. The 128-bit key is programmed during the flashing of the
microprocessor and must match the encoder (SS2000D or SFCDWARE) being used to
activate the unit. A key value of zero disables 128-bit encryption and must be used if the
encoder does not support 128-bit encryption. All sites in the system must use the same
encryption key.

Federal Signal UltraVoice
Installation and Operation Manual
GENERAL DESCRIPTION
20
Security Key
For MSK activated units, the Security Key is a unique number assigned to the system
that prevents nearby systems operating on the same RF frequency from interfering. Like
the 128-bit encryption key, the Security Key is programmed during the flashing of the
microprocessor and must match the encoder. The exception is a key value of 65535
(the default), defined as an “open” system and will communicate with all encoders
regardless of the encoder’s key setting.
User Programs
The UVIC has the capacity to store up to fifty (50) user programs. Each user program
contains the following elements:
1) Optional DTMF Activation Code
2) Optional Two-Tone Activation Code
3) Optional EAS Event Code
4) List of up to 20 functions
The ability to assign more than one function to each activation code or user program is
a new feature not previously found in electronic sirens. This allows the user to run a
sequence of functions without sending additional activation commands, greatly
enhancing flexibility while reducing operator involvement and communication channel
traffic.
