Installation
UltraVoice Indoor Controller (UVIC)
The connector is rated for 50 A. The combined load of the UVIC and the external 24 Vdc
load must not exceed 50 A. Wire gauge and fusing must be selected appropriately for the
load.
600 Ohm I/O Connections
Control Connections
Use terminal block JP12 at the bottom of the system motherboard for making connections
to 600 ohm balanced audio equipment (such as, a direct connection to a 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 of JP8. JP8 is located on the main controller
card. The 600 ohm input can receive audio for control and audio amplification as well as
transmit reports to an external unit.
Audio Connections
To use the 600 ohm input for audio from an external audio source, place a jumper across
pins 1-2 of JP8. Use R123 to control the volume level when used in this mode. Provide
a contact closure at JP15 pins 10 and 11 (PTT: Push To Talk) to turn on the amplifiers
and route the 600 ohm audio to the amplifiers. For best results, use a well-filtered audio
source. Use a shielded audio grade cable and keep the length of the audio cable as short
as possible. Keep away from sources of electrical noise.
Turning on the Power
To turn on the UVIC:
1. Verify all wiring is completed in the previous sections and that the connections are
tight and secure. After the battery connections and antenna connections are made
and the battery disconnect connector is plugged in, the UVIC is running on battery
power.
2. The UVIC control board clock LED begins to blink approximately 3 seconds after
power is applied.
3. Connect AC power and verify that the battery charger LEDs turn on indicating the
charger is charging the batteries.
4. Turn on the radio transceiver power (if applicable) and verify the radio power LED
turns on.
