Description, Specifications, Installation, Operation, and Service Manual
The output voltage is 70 V
RMS
for each of the amplifiers. You may connect up to 400 watts
of speaker loads across the 70 V line for each amplifier.
If multiple separate speaker wire runs must be used for the installation, use an external
speaker wire junction box to simplify field wiring and limit the number of wires in the
UVIC cabinet. (See Installation Instructions for Antennas at the Federal Signal’s website.)
Consult Federal Signal Customer Support with speaker wiring questions. See Getting
Service.
For 25 V speaker operation, install a UV400 in the first amplifier slot. Install a
UVIC25ST in the second slot. Wire the connection between the amplifier and UVIC25ST
using the included cable. Use JP24 Amplifier 2 for all 25 V wiring connections. See the
figure below for wiring details.

PA Audio Connections (JP15)
Connect the optional remote audio input for Public Address to the 600 ohm port on the
motherboard JP12. For best results, use a well-filtered audio source. A contact closure for
remote PTT is required at JP15 to enable the 600 ohm input. Use a shielded audio grade
cable. Keep the cable length as short as possible and away from sources of electrical
noise. See the Level Adjustment Procedures.
For local PA, plug the provided microphone into the 1/4-inch jack on the control module.
Mount the mic on the mic clip located on the access panel. (See “Figure 3 UVIC Parts
