Operations
UltraVoice Remote Interface (UVRI-B)
Relay Output
The UVRI-B provides five high-powered relays for control of external hardware.
Sensor Inputs
Terminal block JP24 is located on the left edge of the UVRI-B control board. Use sensor
inputs to detect and notify conditions occurring at an RTU location.

Common
Spare 1 (JP24: pins 1 and 2)
Use for user-defined application.
Intrusion (JP24: pins 1 and 3)
Alerts the UVRI-B control board when the unit’s door is open. When the door is closed,
the normal operation is for the intrusion switch to be closed.
Solar Sense (JP24: pins 1 and 4)
Use to sense operation of solar charging system.
AC Power/Solar (JP24: pins 1 and 5)
If using AC, 1 and 5 are connected to AC power sensor. Jumper JP24 pins 1 and 5 when
using solar only.
600 ohm PTT (JP24: pins 6 and 8)
Shorting pins 6 and 8 puts the UVRI-B control board in local PA mode.
Solar Mode (JP24: pins 7 and 8)
Jumper JP24: pins 7 and 8 when using solar. This jumper enables solar mode, which
causes the system not to report a failure during low-light conditions or at nighttime. This
is done by locking in a power pass until a master reset. For solar panel testing during the
day, initiate a master reset, wait 15 seconds, and then poll.
Status Monitoring
The UVRI-B uses a variety of sensors to communicate its status back to the Federal
Signal Commander System. This alerts personnel of potential issues at the UVRI-B unit.
The UVRI-B monitors power, battery, door opening, amplifier status and other important
system components. The UVRI-B includes an external fault indicator when any of the
following occur: battery voltage, charger fault, AC power, intrusion, amplifier/line faults,
