Publications
Federal Signal recommends the following publications from the Federal Emergency
Management Agency for assistance with planning an outdoor warning system:
• The “Outdoor Warning Guide” (CPG 1-17)
• “Civil Preparedness, Principles of Warning” (CPG 1-14)
• FEMA-REP-1, Appendix 3 (Nuclear Plant Guideline)
• FEMA-REP-10 (Nuclear Plant Guideline).
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 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, be
available at all times to authorize the activation of the sirens.
• 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
eectively 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. Review and comply with any local or state noise
control ordinances as well as OSHA noise exposure regulations and guidelines.
• Activating the sirens may not result in people taking the desired actions if those to
be warned are not properly trained about the meaning of siren sounds. Siren users
should follow FEMA recommendations and instruct those to be warned of correct
actions to be taken.

Installation
ELECTROCUTION HAZARD: Electrocution or severe personal injury can occur
when making electrical connections, drilling holes, or lifting equipment. Therefore,
experienced electricians, in accordance with national and local electrical codes,
acting under the direction of the installation crew safety foreman, should perform
installation.
EXPLOSION HAZARD: Explosive gases and corrosive materials may be present.
To prevent explosion or severe personal injury, installation technicians must be
experienced with the safe installation of lead-acid type batteries.
SOUND HAZARD: The output level of high-powered speakers is capable of
causing permanent hearing damage. To prevent excessive exposure, carefully
plan placement of siren and post warnings. To prevent excessive exposure to
installers and service personnel, adequate measures must be taken to ensure that
the sirens are not activated while they are within 150 feet of the speaker array or
provide proper ear protection.
This section contains reference drawings to assist with installation.
Control Unit Location
Select a suitable mounting location that is secure, and away from high-voltage wiring and
high-power RF systems. The UVRI-B is available for indoor configurations.
Refer to the specification section to obtain the weight of the UVRI-B. Ensure that the
mounting surface and fasteners can safely sustain the weight of the assembly.
When interfacing to a fire panel or PA system, place the UVRI-B near the panel or PA
system in order to reduce the possibility of introducing noise in the audio path.
Locate the control unit out of the reach of vandals. The UVRI-B is supplied with locking
mechanisms.
The UVRI-B requires a 120 Vac or 240 Vac 50 to 60 Hz power source to power the
UVRI-B and charge the internal 12 V battery. You can configure the UVRI-B to be powered
from 24 Vdc.
You can use several methods to activate the UVRI-B. Use the manual activation buttons
and a hand-held microphone to activate the UVRI-B locally. Use landline control through
