Local PA Audio Connections (J1 on the UVRI-B Control board)
For local PA, plug the optional microphone (part number: MNC-MC) into the 1/4 inch jack
(J1) on the UVRI-B control board. Mount the microphone on the microphone clip located
on the access panel. (See “Figure 1 UVRI-B Parts Layout” on page 17.) Use R3 on the
control board for microphone level control.
The UVRI-B also has remote volume control for optimizing sound levels across your
alerting area. The remote volume control also includes an ambient noise monitoring
capability to automatically adjust volume depending on external noise levels. Use the
recommended microphone (X-SM1-FS1) to monitor noise levels and automatically adjust
the volume. The X-SM1-FS1 is a weather resistant omni-directional microphone for use
with the UVRI-B controller. Mount the microphone in a standard 1/2-inch electrical knock
out or 1/2-inch drilled hole in the UVRI-B cabinet or where the noise is needed to be
measured. The microphone has a 6 foot cord for connecting to the UVRI-B controller.
Remote Activation Contact Closure Inputs (JP22 on the UVRI-B Control
board)
Connect any desired remote contact closure inputs to the remote control inputs at
JP22 on the UVRI-B control board. Activating the input requires a connection of less
than 2,000 ohms from pins 1 or 10 to one of the function inputs on pins 2 through 9 for
functions 1 through 8 respectively.
Optional Powering of the UVRI-B with 24 Vdc (JP23 on the UVRI-B Control
board)
Using an optional cable assembly (part number: Q17501999A), configure the UVRI-B to be
powered by a 20 to 28 Vdc, 24 Vdc nominal supply. The unit may draw up to 7 amperes
at full power. See Figures 9 and 10 for the location of JP23.
To power the UVRI-B with 24 Vdc power source:
1. Disconnect the power transformer connection at JP23 and connect cable assembly
Q17501999A.
2. Connect the red (+) lead and black (-) lead of the cable assembly to the 24 Vdc power
source.
To avoid shorting the output of the charger, do not apply the 24 Vdc power to the
UVRI-B before making the battery connections. See “Turning on the Power” on
page 32 and apply the 24 Vdc power in step 4.
600 ohm I/O Connections (JP8 on the UVRI-B Control board)
Control Connections
Use terminal block JP8 on the UVRI-B control board for making connections to 600 ohm
balanced audio equipment such as a direct connection to an or other type of
control and status monitoring equipment. To use the 600 ohm input for control signal
audio, place a jumper across pins 2-3, (600 ohm RCV), of JP11 and across pins 2-3, (TX
Audio), of JP12. Jumper JP2 (the VOX) to provide carrier detect while the incoming audio
is present. The 600 ohm input can receive audio for control and audio amplification as
well as transmit reports to an external unit.
